How to choose a perfect Laboratory Muffle Furnaces?

When choosing laboratory muffle furnaces, your first concern should be to understand the purpose of buying. Muffle furnaces are ideal for testing materials during any research. It helps to maintain quality control and heat. 

But, every lab has a specific requirement, and there are certain parameters that should not be overlooked. However, it can get confusing to settle for the perfect one with so many different varieties. So, let's get to know the factors that can help you select the best-fitted furnace.

 

Space allotted

You must designate a place in your lab where you are going to keep the muffle furnace. If you have a small lab, then buying a Laboratory Muffle Furnaces can take up all the space making it difficult to move around. 

Dimension of the furnace

If you want to test a polymer sample, then there is a specified size of the chamber for that. But, if you want to test food samples, then you need to pick a different sized chamber. There is a wide range of sizes available, pick the one that supports the purpose.

Temperature control facilities

If you know the working process, then it is a known fact that these furnaces are used for burning a specific sample within the chamber. And, for that, the heating rate matters. Thus, there should be a provision for testing temperature so that you can set it based on the sample being used.

Safety protocols

Always try to test the standards if you are clueless. Further, you must be very much cautious about safety matters. Choose the one that provides an auto-cut off sensor. Thus, preventing the chances of overheating of the coils and averting major accidents. 

Keep away from damaging chemicals

You must maintain a strict precaution not to use toxic or explosive gases along with the furnace. Also, keep away acidic gases and the ones that are marked as hazardous. This not only damages the internal components but also increases the chance of casualties.

Conclusion

If you want a disruption-free working environment, then you need to take keen note of the conditions mentioned above. Global Lab Supply has been offering high-quality muffle furnaces for years, along with expert guidance.

What Is An Laboratory Autoclave & How Does It Work

Every laboratory in the world is likely to have an autoclave to sterilize lab media. Laboratory media must be sterilized to carry out difficult scientific research, regardless of whether the lab is a tiny pharmaceutical startup or a huge institution.

 

A Sterilizing Autoclave Requires 3 Components

Temperature (heat), pressure, and steam are the main components of an autoclave, a popular piece of Science Lab Equipment.

Extremely Hot Autoclaves

The ability of an autoclave to generate steam and increase pressure relies heavily on maintaining precise autoclave temperatures. An autoclave's chamber temperature typically ranges between 121°C and 125°C.

Secondly, A Lot Of Pressure Rises.

Laboratory autoclave use high pressure to get the same results as a regular pressure cooker. The high pressure of a food pressure cooker is used to prepare food rapidly.

Produces Sterilizing Steam

The genuine autoclave sterilization process starts when the steam created by the increase in chamber pressure and temperature comes into contact with the media within.

Autoclave Types and Their Operation

Pre-vacuum autoclaves, often known as pre-vac, are the second most common form of autoclave sterilizer. Glass, liquid media, and laboratory waste may all be sterilized in these two kinds of autoclaves by using various methods of moving steam.

An Overview of Gravity Autoclave Operation

The sterilizing procedure of gravity autoclaves is pretty simple. To generate steam and pressure, the water at the bottom of the chamber is heated directly. As a result of the pressured steam, all previously present ambient air is expelled. The autoclave is set to seal the required valves after the chamber volume has been filled with steam, preventing any further air from escaping. Continuous pressure and temperature building is the method used by the autoclave. In this method, sterilization occurs as soon as the cycle starts.

Autoclaves that use a vacuum system

Gravity autoclaves are more prevalent in labs, while vacuum autoclaves are more challenging to construct. Using a vacuum pump, vacuum autoclaves remove the air from within, enabling steam to enter. Once the chamber has been entirely emptied of ambient air and filled with steam, the procedure is repeated multiple times. The steam can penetrate the medium because of the vacuum function "drawing" the ambient air out of the chamber. Fabrics wrapped goods and sterilization pouches are more suited to vacuum autoclaves.

Things to know about Horizontal Laminar Flow Hood

A complete laminar hood setup describes the airflow pattern. If you're setting up a lab, you may need to adjust the airflow in the space. This mobility is critical in a cleanroom environment as well. The experiment may fail if the airflow direction is not accurate during testing. Laminar flow hoods are used in most labs because of this.

A horizontal or vertical setup is an essential sort of flow hood. The setup aids in ensuring that the airflow remains in the proper direction. Laminar hoods are required if you wish to control airflow in a specific direction. Laminar flow hoods are used in cleanrooms when essential procedures are being carried out.

There Are So Many Reasons Why The Hood Is Very Helpful.

The purpose of the hood in the workstation is more like this. Bench configuration is referred to as the "hood" in this context. The workstations on the bench may be divided into many sections. Lower workstations and higher workstations are the two primary divisions of this space. It's easy to keep things moving, which makes for a cleaner working atmosphere.

Using the Laminar Flow Hood in Action

Sterilized airflow is the primary function of laminar hoods. The airflow's direction is also critical. The equipment will aid in the creation of the air streams. The air streams are produced using specialized HEPA filter devices. The airstream continues to flow in the same direction.

Units That Are Well-Designed

There is no flaw in the hood's construction. The hood's quality may be determined by the engineering methods it employs to guide the airflow. An effective air handling system is a must.

Maintenance Is Easy To Do.

Your workstation's airflow hood device has to be easy to use. In addition, it should be simple to care for and clean. There shouldn't be too many moving parts in the filter. Cleaning the filter unit regularly may be difficult if the design is complicated.

HEPA Filtration Systems

A high-quality HEPA filter is incorporated into the Horizontal Laminar Flow Hood unit. A 95% success rate is guaranteed with this filter unit. It also aids in air purification by trapping many kinds of bacteria. Quality and certified HEPA filters should be placed in the machine you choose.

The Importance of Knowing Your Analytical Lab Equipment

Pharmaceutical, chemical, oil refinery, clinical, and food processing labs all use various types of analytical equipment. Using these tools, the composition and analysis of materials may be determined. There are several kinds of analytical instruments, including refracting meters, spectrophotometers and electrochemical instruments, and titrators, fiberscopes and demagnetizers.

It is possible to modify settings and perform resolution, sampling, analysis and collecting in a more efficient manner with the help of scientific equipment and computers. Global demand for scientific equipment is projected to rise as a result.

• Accuracy
• Sensitivity
• Signal/Noise
• Resolution
• Portability
• The ability to test several variables at once

Analytical instrumentation has advanced tremendously in the last several years. Using personal computers and microcontrollers in analytical devices has become increasingly common in the current age. A substantial number of these devices also serve a crucial role in environmental pollution management and monitoring. Suppliers, exporters and manufacturers of analytical equipment should be trusted.

Conclusion

Analytical tools are becoming more popular due to several variables. These factors contribute to the rise in life expectancy: population expansion, an ageing population, an increase in disposable income, and an increase in chronic illness rates. As more US-based life sciences companies want to expand their regional presence in South America and Africa, prominent players in the industry will have more investment and growth prospects in the coming years. Analytical Lab Equipment are expected to rise in value due to mergers, acquisitions, and divestitures.

Why is a UPS required for a pharmacy refrigerator?

Concerns over vaccine cold chain sustainability are once again being raised after three Covid-19 vaccines were licensed in the USA, and two more are expected to be approved soon.

In A Pharmaceutical Refrigerator, Why Is It Necessary To Have A UPS?

The UPS (uninterruptible power supply) may be used for various purposes beyond those often connected with backup power requirements. Power outages in pharmacy refrigerators and laboratory freezers, on the other hand, restrict medical professionals from opening the refrigerator and retrieving vaccines, which may lead to data loss or other operational concerns. Medicine fridges may keep their temperature for up to four hours after a power outage, as long as the door isn't opened.

As a result of recent news about the development of a Coronavirus vaccine, pharmaceutical refrigerators have come to public attention. It's important to point out the fact that many medications and medical supplies must be stored at a specific temperature range (usually between 2 and 8 degrees Celsius) to ensure their safety and efficacy (35.6F to 46.4F). After 8 degrees Celsius, the NHS Green Book declares that the "cold chain" has been broken, and the contents of the refrigerator must be treated as damaged or destroyed as necessary.

What UPS protects data?

Vaccines must be stored according to tight requirements, which means that a medical fridge outage may not only be an expensive annoyance, but it may also violate laws. For the CDC (Centre of disease prevention), the minimal criteria for acceptable refrigeration conditions:

"Measures have been made to limit the likelihood of an electrical supply being accidentally interrupted."

As previously stated, switchless connectors and unambiguous labelling are common approaches. Although reducing the risk of human mistakes, a switchless socket does not offer an additional source of power to the fridge in the event of a mains power outage.

Conclusion

It is recommended that vaccines and medications stored in laboratory freezers be maintained at a temperature of –15 to 50 degrees Celsius to ensure optimal shelf life. The first Covid-19 vaccination requires a temperature of -70 degrees Celsius (-94F) and can only be thawed four times before it degrades and denatures. Unlike other frozen vaccines, it has a five-day shelf life after thawing.

How to Specify an Ultra-Low Freezer for Lab

To more complex things like cells and tissues, biomolecules such as oligonucleotides and proteins have thermal sensitivity. Ultralow temperature (ULT) freezers must be utilized to keep these materials at -80°C so that they may be examined and characterized. Cryogenic freezers, which can maintain temperatures as low as -150°C, may be used to retain samples for long periods in some instances.

There are a slew of considerations to be made while making your final decision on a ULT freezer

• There are a few things to think about before investing in ULT freezers. In addition to the price, consider the freezer's size, footprint, and energy efficiency.
• The capacity of the ULT freezer is critical because it affects how many biological materials may be stored in the Laboratory Freezer. The larger the freezer's capacity, the more costly it will be to buy and operate.
• It is preferred if the ULT freezer takes up as little space as feasible, enabling the lab to utilize more of the available space for other purposes. ULT freezers that are upright rather than chest-shaped take up less shelf space.
• ULT freezers must keep a stable temperature because biological samples, such as patient tissue, are critical and challenging to obtain.
• The following components make up the user interface: Wi-Fi-enabled ULT freezers of modern models may be controlled from afar. This function might be helpful, for example, if you need to monitor the freezer temperature outside of regular working hours or if the pandemic prohibits you from going to the lab in person.

Because of technology developments, ULT freezers have improved

Biotechnology research relies heavily on the use of Ultralow Freezer. Consequently, their designs have become more imaginative to enhance their reliability and sample integrity while simultaneously reducing operating expenses and enhancing ergonomics.

Manufacturers are upgrading their designs to lower their carbon footprints as consumers become more aware of the carbon footprints generated by research institutions. Some compressors are also equipped with learning algorithms to optimize their energy consumption, making them even more energy-efficient as they become more common.

To reduce the formation of difficult-to-remove frost and ice, manufacturers have created new materials with anti-frost properties that improve temperature uniformity while also making maintenance easier.

How to Properly Calibrate Your Moisture Analyzers

Laboratory-scale To ensure that products meet federal and industry regulations, the moisture content is measured using halogen or other infrared heaters. Like any different exact analytical scale or balance, a moisture analyzer must be accurate to function correctly. To ensure the accuracy of moisture analyzers, two independent calibration processes must be completed: one to ensure temperature and another to ensure weight. If you want to know how to calibrate your moisture balance accurately, keep reading!

Why Do Moisture Analyzers Need to Be Calibrated?

Only a few interruptions may substantially impact the overall accuracy of a moisture balance. The gravitational pull in various locations of the globe necessitates that newly acquired analyzers be calibrated on the spot before they can be utilized. When moisture analyzers are being utilized in the lab or at a different location, even if it's only in a new place of work, changes in ambient conditions might impact accuracy. The workspace should be adequately soundproofed and heated or cooled to prevent noise and temperature fluctuations brought on by moving carts over the floor.

It is necessary to calibrate the weighing system

It is necessary to do external calibration on moisture analyzers to be as accurate as possible. These adjustments are made by combining a particular moisture balance test with predetermined adjustment weights like 50 grammes. The operating instructions accompanying the devices provide information on how to calibrate different models of moisture analyzers. The calibration weight is placed on the sample pan once the device has been set to suit the importance of the pan. For example, if the moisture analyzer shows an incorrect number for the real weight, the analyzer will automatically correct itself, and the exercise will be completed without additional input.

Temperature Testing And Determination

Heating systems may be calibrated using temperature calibration kits, which can be purchased separately. However, your moisture analyzer must be cooled down for three hours before any tests can be carried out. Insert the temperature probe as close to the sensor as possible, following the instructions in the instruction manual.

In comparison to the weight calibration technique, the temperature checks are more time consuming and require the use of two independent pounds. A moisture balance can only offer accurate findings if it is calibrated regularly in your laboratory. All laboratory employees must be aware of the calibration procedure and its timeframes.
