Advantages

Lab ovens have become more energy and work efficient. Laboratory ovens with easy programming, automation, and greater drying efficiency can get you up and running quickly. Whether your lab oven is for drying, aging, softening, or sterilizing, we have a variety of the latest heating technologies. Choose from a wide selection of temperature and capacity ranges. Our ovens are manufactured to the strictest quality standards and are recognized industry-wide for their outstanding performance and reliability.

Applications

Ovens are among the most universal pieces of equipment found in laboratories and can be divided into three general types: gravity convection, mechanical convection, and vacuum. Cole-Parmer offers all three types of ovens.

Gravity convection ovens are used in applications where close temperature tolerances are not essential. Mechanical convection ovens, on the other hand, provide a more sensitive response for better temperature control, uniformity, and stability. Vacuum ovens are used for applications which require an airless environment. Vacuum is also used to enhance evaporation of solvents by lowering the evaporation temperature of the solvents. Vacuum ovens are thus used to extract volatile material from heat-sensitive samples.

The type of laboratory oven best suited for a particular application will depend on several factors, including maximum temperature required, temperature uniformity, sample size, and budget.

Cole-Parmer ovens are suitable for a wide range of general laboratory, biomedical, and industrial applications.

Choosing the Correct Oven for Your Application

Cole-Parmer Laboratory Ovens are available in a wide range of sizes, features, and performance characteristics. Here are some factors to consider to help you choose the Cole-Parmer oven best suited for your specific applications.

How will the oven be used?

Chamber loading - If the chamber will be loaded to more than 50% of capacity, mechanical convection is recommended to ensure optimal heat distribution.

Importance of temperature uniformity - Mechanical convection generally provides better temperature uniformity.

Types of materials being dried or heated - Gravity convection ovens are best suited for drying powders, loose materials, and delicate samples.

What is the maximum temperature at which you will operate the oven?

Oven temperatures generally range from 200°C to over 300°C respectively. If the maximum temperature required is right at the upper limit of the oven’s temperature range, an oven with a higher temperature range may be more suitable.

What type of controller do you need?

The Cole-Parmer oven product groups offer a PID controller for accurate and reliable temperature control. This is far superior to old analog controllers. Our PID controller also offers flexibility for temperature and time input with delay start and other convenient options for input.

What size chamber is needed?

What is being loaded in the oven is most important. Tall glassware or pipette holders (which are 24" high) may require a larger chamber than small weighing dishes, crucibles, etc. The type of material being loaded will also influence the need for additional shelves.

The amount of available bench space is also important. All Cole-Parmer ovens are designed to require very little benchtop space.
