A Comprehensive Guide to Vacuum Desiccators

Desiccators are sealed containers that are used for drying samples under atmospheric pressure or vacuum pressure. These can also protect chemicals that are hygroscopic, as well as protect samples from dust and moisture in the air. Desiccators can be made of glass, polypropylene and polycarbonate, or acrylic in cabinet form.

Desiccators:

Glass Glass desiccators are made from borosilicate glass which makes the desiccator more robust. However, these desiccators can shatter and it is recommended that these desiccators are placed behind a screen when under vacuum.

Polycarbonate And Polypropylene Polycarbonate desiccators are shatterproof and implosion proof, giving them high impact resistance and allowing them to withstand high vacuum pressures.

Vacuum Vacuum desiccators can dry samples in two ways under vacuum or by using a desiccant. Drying under vacuum uses a vacuum pump to remove any air from the system. Inert gases, such a nitrogen gas, can be used to achieve ultra-dry environments. Desiccants can help induce or sustain dry environments depending on the moisture content of the air and sample.

Non-vacuum Non-vacuum desiccators can also dry samples in two ways using desiccants or by purging. Purging of a desiccator uses either an inert gas, such as nitrogen, or compressed dry air to reduce oxygen levels. This desiccator uses atmospheric pressure to dry the chemicals.

Acrylic Cabinet Desiccator Cabinets can lower humidity levels and prevents moisture and [dust from damaging samples. These cabinets use a desiccant or an inert gas to remove moisture. The cabinet is preferred when drying bigger samples or a large quantity of samples at the same time. The shelves are adjustable to accommodate taller samples, and most cabinets are clear to easily see samples inside.

Stopcock

Stopcocks are used on vacuum desiccators to help evacuate the liquid or gas from inside the desiccator. This helps to reduce the chances of the desiccator from imploding as the stopcock can reduce the pressure inside the desiccator if opened.

The Best Vacuum Glove Boxes: A Comprehensive Guide To Choosing the Right Product

A vacuum glove box is a fairly simple piece of equipment consisting of a vacuum chamber with gloves extending into it. A vacuum pump pulls the air out of the chamber, creating a low-pressure, low-moisture environment, and the gloves allow the operator to manipulate anything inside in the chamber.

Often this is combined with the re-introduction of inert gases into the chamber such as nitrogen or argon, allowing the operator to do experiments or perform other operations on the contents of the chamber in an inert atmosphere that prevents contamination with reactive gases like oxygen or liquids like water. This also adds an element of safety because an inert atmosphere is non-combustible. Most vacuum glove boxes are made out of acrylic, allowing the operator to easily see inside the chamber while they’re working on the chamber contents.

Vacuum Gauges for Vacuum Glove Boxes

Most vacuum glove box operates in rough vacuum (10-3 Torr up to 760 Torr or atmosphere), so any of our rough vacuum gauges are an excellent fit for a wide variety of vacuum glove boxes. For a standalone active gauge, check out the MX2A thermocouple or MX4A convection active vacuum gauges. If you’d prefer a rack mountable controller, check out the MV2A controller and the 2A passive thermocouple vacuum gauge.

What Are the Advantages of an Ultralow Freezer?Benefits Of Using An Ultrasonic Cooler!

Ultra-low temperature freezers (ULT) are used by laboratories for storing drugs, enzymes, biological materials, tissue samples etc. Maintaining a temperature between -30° to -40° Fahrenheit, the low temperature is ideal for storing sensitive materials that have high perishability. Today they are useful for storing the COVID-19 vaccine and are significant to public health. The freezers are essential in labs that work with and analyse a variety of bio specimens and enzymes.

 

Ultra-Low temperature freezers are not only reliable for storing sensitive substances but also provide other advantages like energy conservation, noise reduction and many other such features that impact the regular workflow in the laboratory and operational cost.

There are two basic types of ULT freezers —upright freezers and chest freezers. The latter is more efficient than the former, but is generally not preferred because of usual space limitations. In fact, chest style freezers account for less than 5% of ULT freezer sales. Yet, these freezers have a longer service because they have an efficient design which requires only minimum usage of compressor. The same efficiency makes it possible to reach temperature set points more rapidly and this is maintained continuously.

Intact sample health

The Ultralow Freezer is a safe sample freezer that provides a stable deep-freezing temperature for essential microbiological samples that require stability and ultra-cooling. Scientists and technicians can rest assured that the specimens are well preserved despite power failure. The seven-point contact silicon gasket maintains the temperature and prevents leaks. The temperature recovery system is also instantaneous in these deep-freezing systems. Deep freezing in microbiology is essential and with a ULT freezer, you can rest assured that optimum temperature will be maintained.

Highly energy efficient

Expending 25% less energy than any standard equipment, the energy consumption in these freezers is remarkably low. Choosing the right freezer will ensure that the equipment emits less heat within the lab atmosphere and functions with less noise helping scientists to focus on their work. You do not have to worry about an additional increase in power bills with the inclusion of an Ultra-low temperature freezer in your lab, this cost-efficient deep freezer in microbiology labs adds effectively to research. They are highly valued in hospitals for preserving blood samples.

Security added value

Ensuring the safety of the specimens inside the lab, the freezer requires an access authorization key card. Unauthorized entry will activate the alarm raising an alert of spurious infringement. Fingerprint scanners are also a feature supported by many Ultra-low temperature freezers.

What Exactly is an Incubator? The Complete Guide To Understanding Microbiological Incubators

A laboratory incubator is a crucial equipment in any laboratory. They provide a controlled, contaminant-free environment for safe, reliable work with cell and tissue cultures by regulating conditions such as temperature, humidity, and CO2.

What is a laboratory incubator?

It is a heated, insulated box used to grow and sustain microbiological or cell cultures. The laboratory incubator does this by maintaining optimal temperature, humidity, and gaseous content of the atmosphere inside. The microbiological incubators differs in size from compact table-top units to large systems, the size of a cupboard.

The simplest incubators offer only a little more than being temperature-controlled ovens, that are capable of reaching temperatures of 60 to 65°C, but generally used at about 36 to 37°C. A large amount of modern incubators can also generate refrigerated temperatures, and control humidity and CO2 levels.

What is a laboratory incubator used for?

The primary function of an incubator is to endow a controlled, contaminant-free environment for safe and reliable work with cell and tissue cultures by regulating conditions such as temperature, humidity, and CO2. Laboratory incubators are fundamental for the growth and storage of bacterial cultures, cell and tissue culture, biochemical and haematological studies, pharmaceutical work and food analysis.

Incubators are often deployed in modern research laboratories to preserve a stable atmosphere for processes such as growing cells and microbiological cultures and incubating antibodies and cells for fluorescence microscopy.

A common misconception is that ovens can be used in place of incubators because they both produce heat. However, they are not the same, as an oven produces temperatures typically ranging from 93.3 to 316 degrees Celsius, while an incubator typically ranges from 15.6 to 48.9 degrees Celsius. Therefore, an oven cannot be used as an incubator because most ovens will not have a low enough temperature that is suitable for using as an incubator.

Laboratory Incubators are used for growing cell cultures, reproduction of germ colonies with subsequent germ count in the food industry, reproduction of germ colonies and subsequent determination of biochemical oxygen demand in wastewater monitoring, reproduction of microorganisms such as bacteria, fungi, yeast or viruses; breeding of insects and hatching of eggs in zoology, controlled sample storage and in growing of crystals/protein crystals.

Types Οf Transport Carts That Can Be Used In Laboratories

Transportation carts or goods carts are becoming more common in industrial laboratories. These laboratories need a ton of supplies regularly and moving a huge amount of supplies can become a daunting task for humans. So, these carriers are used to move things efficiently and faster. There are different types of laboratory transport carts that can be used in a laboratory.

Some of the most used carts are:

Hand Trucks- These are off of the most common and most used carts. Hand trucks are affordable and easily available. It is basically a cart with one pair of wheels and operated manually, this cart has a toe plate to store the equipment of goods and a long frame supports the weight of the goods. This cart is pulled backward during transportation. Hand trucks are often modified to move barrels of liquids or jars with safety. Some carts also have a latch to keep the goods secured in places during transportation.

Pallet trucks-   Pallet trucks or jacks are used if a laboratory needs to move palletized loads from one place to another. It comes with a parallel platform that lifts things and moves things. These carts can also be used to unload a larger supply. It is more common in pharmaceutical labs which need to send many batches of goods per day.  It has a fork under a pallet. The cart driver lifts a hydraulic jack to move the platform upwards to downwards, there are manual pallet trucks, gas-powered trucks, and electric jacks.

Go carts- Go carts are small versions of a four-wheel car. These carts are automatic and can carry a lot of loads. Go Laboratory Carts carts can be electric, gas-powered. The go-carts often have a load area where materials are stored for transportation.  But, they do not have any suspension.

A-Frame trucks- It is another cart that is used to transport panelled goods. These have flatbed trucks. The trucks have some vertical dividers. The panels of products are liquid in between the panels. Some carts have a larger load capacity.

A Simple Guide To Lab Moisture Analysis: Everything You Need to Know About It

Moisture analyzers, also known as moisture meters or moisture balances, measure the moisture content in samples. They can analyze gases, liquids, and solids and are particularly important pieces of equipment when it comes to testing certain types of products such as pharmaceuticals, food, plastics, fuel, and hydrocarbons. In this post, we reveal how moisture analyzers work and best practices for using them.

How Moisture Analyzers Work

The premise behind lab moisture analyzer is quite simple. They work using a Loss On Drying (LOD) or thermo gravimetric method to determine how much moisture is in the sample. Here are the basic steps:

• The moisture analyzer weighs the sample and records the initial weight.
• A heating element radiates infrared heat to dry the sample. (A few different types of heating element may be used in moisture analyzers, including halogen lamp, quartz lamp, metal, or ceramic.)
• The sample is weighed periodically until the weight no longer changes (this means the sample is fully dried).
• The final weight is subtracted from the initial weight to determine the moisture content.

If you need to find out the solid content of a sample, you simply subtract the moisture content from the initial weight.

Note that moisture doesn’t only refer to water. It includes any substance that will evaporate as a result of infrared heating, for example, alcohols and organic solvents.

Best Practices for Using Moisture Analyzers

Here are some tips to help ensure you get accurate results when using a moisture analyzer:

• Position the analyzer correctly. Make sure the unit is placed away from any sources of draft or vibration such as air vents or refrigerators. It should also be in a non-harsh, clean environment. High humidity, extreme temperatures, or excess dust could affect the accuracy of results.
• Take safety precautions. Assess the risk involved in heating your particular sample. Work in a fume hood where necessary and never try to dry explosive or combustible substances.
• Use clean sample pans. Used pans should be disposed of and you should only use clean, intact pans.
• Ensure an even sample spread. You should cover the entire surface area of the pan with a thin, even coating of sample.
• Don't overload the unit. Be sure to note the maximum capacity of the analyzer as overloading it could damage the internal weighing mechanisms.
