Laboratory Ovens with Controlled, Uniform Temperatures and with Energy-Efficiency
You have to know your laboratory ovens because they’re not all the same. You get high temperature ovens, wax melting ovens, heavy duty ovens, vacuum ovens, standard digital ovens, materials testing ovens, drying ovens, soil drying and aggregate ovens, hot air sterilizers, dual purpose ovens and energy efficient ovens among others. The energy efficient ovens are popular now because of the global energy crisis. Laboratories need to be cost-effective because they’ve got experiments going and equipment running continuously. Typical sizes of these laboratory ovens are from one cubic foot to as much as 32 cu ft. With the smaller ovens, they can sometimes be stacked one on top of the other.
The laboratory oven is an invaluable appliance because it enables temperature stability for safety while drying glass and plastic. These ovens are used principally for drying glassware as well as heat-resistant equipment.
Laboratory ovens are perfect for many purposes and environments. There’s an oven for every use, from removing moisture to changing chemical and physical properties.
Just some of the characteristics people look for when considering purchasing a laboratory oven –
● good fair pricing
● good safety features
● simplicity and ease of installation and use
● generous warranty
● smallest footprint possible
● low operating- and low maintenance costs
● broad temperature ranges
● controlled airflow so as to ensure uniform temperature
● good support services after purchase
The ovens maintain temperatures from ambient to about 300°C and are used in many different industries as well as environmental labs. Those units which operate at temperatures above 300° C are usually used for specialized electronics applications. Laboratory oven applications are expanding beyond just drying, and you’ll find chemists who use these ovens for other things such as determining moisture content in foods, for die-bond curing, polyimide baking and sterilizing.
Precise Air Flow Pattern
Airflow patterns increase drying and curing efficiency. Laboratory ovens suit the needs of those who require precise temperature control, heat distribution as well as safety features. Safety is always important and you’ll want to look at an oven that has an automatic turnoff for when the unit overheats as well as flaps for venting chemical fumes. Temperature control- and distribution are sought after features in a laboratory oven.
You can say that the most important consideration when buying an oven is the type of temperature controller available. Controllers work through a thermostat to turn the oven on and off when desired temperatures are reached. A PID controller or proportional integral derivative controller is a popular choice for applications where precise temperature control and uniformity is required.
Do research and choose the right oven from a well known brand. Lab ovens have many capabilities and configurations to meet your specific thermal-processing applications.
