Vacuum Oven: 5 Things You Need to Know



Reliability, affordability, and efficiency are common problems with ovens. You might decide to experiment with different brands and models. However, it’s impossible to take that gamble without incurring massive losses. 


But have you heard of the vacuum oven? Below you’ll learn all about the machine, its usefulness in the laboratory, and its features.

Why Do Laboratories Need a Vacuum Oven?

Scientists need accurate analysis techniques to make breakthroughs in their work. And that process means maintaining high-quality samples because any slight impurity can change the results significantly. Moreover, those analysts need top-tier equipment that doesn’t blow away their powdered samples.


What’s the solution? The researchers use vacuum ovens for experiments that need drying. Those machines help them create an environment with high heat and low pressure. Consequently, they can process delicate or heat-sensitive samples and prevent their degradation.

How Does a Vacuum Oven Work?


Oven creators use the hydrostatic pressure principle to help you save time, energy, and the integrity of your samples or microchips. To elaborate, the boiling point of any solvent in a vacuum reduces from its standard temperature to a lower point. The liquids then convert to a gaseous form quickly.


Why is the low pressure essential? The low tension is vital because vapor molecules disperse more easily and collide less, thus allowing them to escape without heat wastage. Consequently, the oven will save you energy costs by running your reactions effectively.


The oven maintains a stable vacuum environment by regulating the amount of air going in and out of the chamber. A pump helps the machine achieve that effect fast.


Vacuum ovens maintain balanced temperatures where the chamber isn’t too hot to damage your sample or too cold to cause vapor condensation. Therefore, the machine heats your samples at the ideal temperatures and removes the vapor produced quickly by maintaining constant entry and exit of the gases. Examples of inert gases used include xenon, nitrogen, or helium, as those molecules don’t cause oxidation.

What are the Benefits of a Vacuum Oven?

Dry Heat-Sensitive Materials

The vacuum oven is ideal for drying delicate samples because it doesn’t store up the heat. And as soon as temperatures rise above the required level, there’s a pump that expels away the hot air. Additionally, you’ll remove excess moisture from your substances by reducing the solvent’s boiling point.


You’ll vacuum dry porous samples, complicated electronic parts, and granular substances that don’t dry quickly. And the fast vacuum creation and cooling system allow you to carry out multiple procedures seamlessly.

Enhanced Safety and Durability

Inert gases present in the vacuum chamber prevent explosion accidents in your laboratory. And in case of any mishap, technicians fortify the machine with a stainless steel double wall supported by thick glass. Moreover, you’ll protect your lab personnel’s health when heating toxic samples because the oven has an outlet to expel those fumes.


The oven is easy to clean because of the stainless steel walls. Moreover, your appliance won’t get damage caused by rust because there’s no air access from the outside, which could cause oxidation.

Preserve Sample Integrity

Do you want to dry powdered samples but are afraid they’ll blow away? Don’t worry. The oven works in a vacuum chamber with no airflow, meaning your substances will be as you left them. And that mechanism is unlike the traditional ovens using the air circulation method.

What are the Features of a Vacuum Oven?

  • A vacuum range of -750mmHg ensures maximum efficiency.
  • It has a high temperature of up to 200 °C.
  • The PT100 temperature sensor helps regulate the temperature.
  • It has a digital PID temperature controller displaying set value (SV) and process value (PV).
  • The oven has a high-temperature silicone gasket.
  • You’ll get removable shelves and an oven capacity of 21 liters or more. 
  • An oil-free pump to hasten vacuum creation and maintenance.
  • It has a recorder, timer, and alarm to help you monitor your procedures.
  • The oven has a built-in cooling system to improve the speed of your procedures.
