What Are Gravity Convection Ovens, and Why Do You Need One?

 

Gravity convection ovens for laboratories have a unique design that works without using any blowing fan. It works on the principle of thermal expansion of hot air, which proves to be a cost-efficient alternative. They're also better at retaining heat and drying chemical compounds to yield better results in any thermal expansion.

These gravity convection ovens prove to be of great help in certain sensitive experiments, temperature control, and evaporation of chemicals. However, a brief introduction to the basics of gravity convection ovens is essential to make the best of use.

Gravity Convection Ovens For Lab                 

Gravity convection ovens work by air currents that form due to thermal expansion. The hot air rises, hit the ceiling, and then falls back down continuously, resulting in uniform heating of the material within the oven. Gravity convection ovens are designed with a separate entrance and exit to ensure that items placed within do not get burnt or damaged due to direct contact with hot air.

The working mechanism of Gravity Convection Ovens is similar to that of forced convection ovens; they differ only because they don't use any blower fan or circulating pump. Instead, the heated air inside the oven rises upwards by buoyancy while cool air flows in from the bottom, which in turn helps heat the material inside.

Why Do You Need One?

In addition to saving cost and energy, gravity convection ovens are ideal for drying chemical compounds. The air within is heated along with the material placed in them, and the convection currents lead to an even distribution of heat.

Temperature can be easily maintained at the desired level by controlling the flow of coolant from the bottom. This allows you to adjust the temperature per your required field and get optimum output. Take a look at these pointers to understand the importance of these ovens in your lab:

ü  Control Temperature

Since these ovens work without electricity, they allow easy temperature control. You can easily adjust the heat and maintain it at the desired level. In addition, the flow of coolant from the bottom can be adjusted as per requirement, which further helps to keep the temperature at an optimum level.

ü  Uniform Heating

The heating in gravity convection ovens is uniform throughout because the air currents induced are balanced and don't end up affecting a particular area within the oven, like in forced convection ovens where heated air rises. However, hot air tends to hit one side of the material placed due to a lack of airflow.

Thick glass makes up the walls of these ovens, which helps retain heat for a long duration; this proves helpful in temperature-sensitive experiments that require heating or cooling at a constant rate over a long period. For example, it can help dry different chemical compounds by evaporation.

Four Features of a Premium Quality Cleanroom Table

 If you're in the market for a new cleanroom table made of high-quality materials and advanced functionality, you've come to the right place. Unfortunately, with different companies selling different cleanroom tables, finding the best pick for the bench is not always easy.

However, there are a few things you can look for while buying cleanroom tables for your laboratories. Below are some features of a premium quality cleanroom table that will make your work easier, more efficient, and safer than ever.

1.      Heavy-Duty Steel

A premium quality cleanroom table is made of heavy-duty steel to withstand the repeated use and abuse of working in a lab or industrial setting. The thick metal legs are designed so they can't be accidentally knocked over, while the round edges will avoid awkward collisions when they inevitably happen. The table must be made from heavy duty steel with long shelf life. 

2.      Noise-Absorbing Foam Cushions

While buying Cleanroom Tables, make sure they have soft and comfortable foam padding to keep the surface of your workstation and your equipment in pristine condition. These noise-absorbing cushions prevent excess vibration, which can damage sensitive equipment. The foam is also sealed so it won't absorb water, oil, or other chemicals that may splash onto the cleanroom table.

3.      Casters with a High Grip Surface

Casters are essential to a high-quality cleanroom table because they provide balance and mobility for your workstation. A premium quality cleanroom table will have a smooth, solid surface to enhance your working grip. Additionally, the wheels are made of heavy-duty steel to ensure they won't be easily knocked over.

4.      High-Quality Safety Locks

A premium quality cleanroom table is made with safety locks so your workstation can remain in place while you're working or when a spill or spillage happens. The safety locks are designed to prevent accidental falls and keep the workstation stationary. A premium quality cleanroom table will protect your employees from hazardous spills and leaks and keep your sensitive equipment in pristine condition to maximize productivity in all areas of your business.

5.      Easy Assembly

We all know it is hard to assemble a cleanroom table and its components, but a premium quality cleanroom table will have straightforward assembly. In addition, the parts are already pre-packaged, so you don't have to be concerned about installing them incorrectly or making mistakes while building your cleanroom table. A premium quality cleanroom table will also require minimal maintenance, which can prevent unnecessary costs down the road.

Conclusion

Many types of cleanroom tables are available to the manufacturing, biotechnology, and testing industries. However, not all cleanroom tables are created equally. That's why purchasing a high-quality workstation will provide stability, safety, and comfort for your employees and workers is important. 

Why are Laboratory Ovens Essential for Every Lab?

Laboratories are essential for all types of experiments, and a standard lab should have a range of equipment. Laboratory ovens are an indispensable part of every lab because they can be used for many different things. In addition, a laboratory oven is more accurate than an ordinary kitchen oven at very low or high temperatures.

These laboratory ovens are important to a laboratory because they can heat substances to test how certain temperatures affect the properties and reactions, i.e., thermal analysis. Consider these below-shared points to understand the importance of laboratory ovens:

Ø      Supports Heat Related Experiments

A laboratory cannot work without ovens because they can complete different experiments, such as melting and crystallization, with caution, heating, and mixing up compounds. It can also be used for drying solvents so that they will be able to evaporate more easily from solutions when needed, making it easy for labs that need a lot of samples dried quickly.

Ø    It fits Different Types of Sample Sizes

These Laboratory Ovens are the perfect tool for labs because they can dry different types of samples in different sizes, such as catalysts, ceramics, and glasses. It can also heat any item that needs to be heated up, but it has a smaller diameter than the kitchen oven. Additionally, these ovens are more accurate at lower and higher temperatures than conventional forced air ovens.

Ø     Saves Time and Money

It is essential to know that the rates at which samples are heated in a lab are much faster than what you will find in an ordinary oven. This is because these ovens have thicker walls, allowing them to retain more heat than what you will find from other types of kitchen ovens. Also, using a lab oven doesn't cost to lose of the quality of the substances after being heated, making it an important material for all types of labs.

Ø     Can be Used for all Types of Experiments

Many experimenters find that laboratory ovens are crucial to their experiments because they can heat all kinds of samples so that they can be done in a short time. This will lead to getting the desired results faster, leading to more accuracy and precision in their experiments. In addition, it is also important to know that a lab oven is not only used for heating substances; its potential applications also include drying solvents and other materials like glassware, ceramics, and catalysts.

A laboratory is incomplete without an oven because it is a critical piece of equipment for all types of experiments, and there will not be any other way to heat or test temperatures properly. Furthermore, an oven is essential for laboratories because it helps achieve the most accurate results in experiments.
