If you are drying, softening, curing, or sterilizing a product you have a choice of vacuum ovens to get the job done in your laboratory environment. Cascade offers both vacuum ovens and laboratory ovens to remove moisture, solvents, and other contaminants from a product. Which oven is right for your application? There are several key differences between vacuum and forced-air drying, but the main takeaway is that vacuum ovens are ideal for products that are temperature sensitive. A vacuum oven removes unwanted compounds using a change in pressure at a temperature that won’t harm the product. Laboratory drying ovens, on the other hand, use heated air to remove unwanted compounds, and, because they do not need to withstand the pressures of vacuum, laboratory drying ovens can be more cost-effective and drying can be done on a larger scale. The guide below will help you determine whether you need one of Cascade’s vacuum ovens or Laboratory Drying & Decarboxylation Ovens that offer forced-air or convection style drying.
Vacuum Ovens For Drying
Ideal Drying For:
- Temperature-sensitive products that will be adversely affected by heat
- Where gas, moisture, or material is trapped in the product.
Vacuum ovens are ideal for the removal of trapped water, solvents, or other volatile compounds from a product that is temperature-sensitive. Vacuum ovens remove unwanted molecules by reducing the pressure (creating a vacuum) in the oven. When the oven pressure reaches the desired vapor pressure of the contaminant, those contaminant molecules volatilize, turning into a vapor, and are removed from all regions of the product. This outgassing or purging is done without the use of excessive heat. Industries such as biopharma, aerospace, PCB, and medical device manufacturers use vacuum ovens as a part of a finishing process in the manufacture of materials. Surfactants, water or gas bubbles that become trapped in between product layers, or “nooks and crannies”, during the manufacturing process need to be removed before the product is ready. A vacuum oven will liberate these compounds with a change in pressure at a temperature that won’t harm the final product. Unlike other mass-produced vacuum ovens, Cascade’s Vacuum Ovens provide superior temperature control to minimize overshoot and maintain temperature stability during purging, and vacuum outgassing. Cascade’s control logic understands how our customers use the oven and makes sure the controller responds to certain process events to keep the temp on track. To that end the temperature probe is INSIDE the oven, providing accurate, even, stable temps throughout – making accurate use of every inch of shelf space. Clients use Cascade’s line of vacuum ovens to help products achieve the desired consistency, or pass inspection for cleanliness. In bio-pharma applications, the removal of medical-grade solvents using Cascade’s vacuum ovens can help make a product fit for human ingestion. Cascade vacuum ovens are also used to simulate the vacuum of space for aerospace and satellite applications.
Vacuum Ovens With Vacuum Pumps
As you’re selecting a vacuum oven keep in mind that vacuum ovens require a vacuum source, typically a vacuum pump, or in-house vacuum. Cascade offers a wide variety of vacuum pumps, each type having it’s own ideal use for specific applications. Learn more on our Vacuum Pumps page.

Laboratory Drying Ovens
Ideal Drying For:
- Cost-effective drying, curing, baking using higher temperatures (up to 300C)
- Products that do not heat sensitive
- Curing or setting up epoxies, coatings, resins
- Lab-scale research
- Decarboxylation – using heat to cause a chemical conversion/reaction in a compound
- Largest scale capacities
Laboratory drying ovens fall into many categories. When you see the term “forced-air” or “convection” in the description, it means that air is heated and directed (typically with a fan motor assembly) across or around the product. Terms such as “gravity”, or “gravity-convection” mean that the ovens do not have a fan motor and simply rely on the principle that heat rises to move heat inside the oven and around the product. Cascade only offers forced-air or convection style drying with horizontal airflow that enables a more consistent distribution of air. Our ovens are designed to have uniform temperatures and airflow across the shelf space from right to left. Forced air drying is typically utilized in larger-scale industrial drying applications such as curing or setting up epoxies, resins, and potting materials where the product is not temperature sensitive. Because they do not need to withstand the pressures of vacuum, laboratory drying ovens can be more cost-effective and drying can be done on a larger scale. Cascade’s Laboratory Drying & Decarboxylation Ovens can be used in a variety of industries and applications such as agriculture, R&D facilities, and university research labs. Clients use Cascade’s line of Laboratory Drying & Decarboxylation Ovens to dry soil samples or decarboxylate plant material. In smaller lab-scale environments our ovens are used in R&D facilities and at universities for research purposes.
