WHAT IS VACUUM OVEN?
Vacuum Oven is a high temperature technology equipment and fully sealed chamber that heat samples in the presence of air or other gaseous atmosphere. They work over a wide temperature range, and that’s why they are also called high temperature ovens. It can be used in various applications, such as hardening, casting, material testing and chemical analysis of complex substances or in the quantification of metals, whether in laboratories or industries.
Vacuum Ovens are available in a wide variety of configurations and temperature ranges. The vacuum oven has a simple and conservative design, which makes this type of oven very versatile and trouble-free. These are constructed with a heavy gauge steel housing and low density heating elements, plus lightweight ceramic fiber insulation, making these ovens suitable for any industrial or laboratory application.
FEATURES TO CONSIDER WHEN LOOKING FOR A VACUUM OVEN:
Types of Vacuum Oven
Vacuum Oven can have different applications: incubation, sterilization, drying: conventional, vacuum or forced ventilation and development with emphasis on several characteristics that can be controlled inside the chamber: humidity, photo stability, gases, temperature.
Look for a model with a maximum temperature higher than that required for testing. This ensures greater accuracy and uniformity during operation, as well as longer service life, as the thermostat, controller and heating elements do not have to work as often or as often.
Heat is distributed throughout the chamber of a laboratory Vacuum Oven, either by gravity convection or forced ventilation.
Gravity convection ovens depend on differences in temperature and density in the air for circulation in the chamber, and this can result in dead spots. These ovens are ideal for simple drying applications or in cases where strong drafts can displace light sample materials. They are generally cheaper to buy and operate.
Forced ventilation stoves have fans that actively distribute air through the Vacuum Oven chamber to produce uniform heating.
The internal dimensions of the chamber are an important factor to consider.
Uniformity in a laboratory oven is a measure of how consistent the temperature remains at various points in the chamber. Hot or cold spots affect overall accuracy and may affect test results.
You must know the capacity and configuration of your electrical supply and the type of connection required to the stove before purchase.
Opening the oven door frequently to add or remove samples puts an additional load on the system while trying to compensate for heat loss. A short temperature recovery time is a desirable performance feature, but it requires additional power. If your specifications demand a high level of uniformity and accuracy, a shorter recovery time will be important to you. Otherwise, heat loss can be satisfactorily controlled by limiting the door opening frequency and maintaining an adequate sample charge in the chamber.
Many laboratory greenhouses feature stainless steel interiors and shelf construction to resist corrosion and deterioration. If your materials aren’t particularly corrosive, you could consider a model that has a galvanized or galvanized steel interior as an economical option. Double wall construction and good insulation make the oven more economical to operate, more uniform and operate with a cooler outer surface for greater safety.
Many controller options are available in Vacuum Oven, from simple analog dial controllers with bi-metal thermostats to highly accurate programmable digital models with self-diagnostic, logging and calibration functionality, some even with remote web access. Cool stuff, but you’ll have to balance the cost of the features with the benefits. If your laboratory is understaffed, it will be helpful if your stove has set points for temperature protection and remote, automatic, or time-definite operation.
