Forced Convection Oven
JSOF-Series Forced Convection Ovens utilize a motorized fan to force air circulates across heating element to supply hot air into the chamber. The fan allows more consistent temperature distribution of the chamber for applications in which good temperature uniformity or faster heat up and short drying time are needed.
Natural Convection Oven
JSON-Series Natural (Gravity) Convection Ovens heat up chamber by mild gravity air convection with heating element located on the chamber bottom. Ideal for drying fine powders, general and conventional laboratory drying applications.
Upright Convection Oven
Upright Forced Convection Oven provides a big volume of chamber for large scale laboratory or industrial purpose. Nevertheless its large volume, dual heating system on upper and lower compartment with two separate heating elements and blowers provide better air circulation throughout the chamber to achieve excellent temperature uniformity and faster heat up time.
Compact Oven
Compact Oven is a common and universal instrument to be used to drying, heating and sterilizing objects by heating air up to 250°C with gravity or forced convection system
Vacuum Oven
Vacuum Drying Oven is suitable for drying out liquids or solvents contained in a samples or materials in vacuum environment to achieve low heat of vaporization or sublimation point. Ideal for Vacuum Distillation, Vacuum Sublimation or Vacuum Drying application of material science or electronic parts and assemblies. Also suitable for drying out fine powders in vacuum environment without air convection to prevent diffusion of such samples. Drying, curing, de-gassing, aging, removing moisture or solvent from fine powder or solid material, accelerating drying time, drying temperature sensitive material, drying in anaerobic condition, remove solvent from DNA, RNA or protein, drying unidentified material characteristic.
350°C Hi-Temp Oven
High-Temp. Forced Convection Ovens provides higher temperature up to 350°C than conventional ovens for special application for material research or testing laboratory. Motorized fan to force air circulation across heating elements and circulates into the chamber. The fan allows more consistent distribution of air and optional inert gas (Nitrogen Gas) purge system allows control oxidation of samples at high temperature treatment
HEPA Filter Clean Air Oven
Clean Air Oven is mechanical convection oven equipped with HEPA Filter Class H14 in laminar air path to remove particles up to 99.995% to keep oven chamber as clean room condition. Designed for applications drying or curing dust sensitive materials such as electronic components or medical parts, semi-conductor chip cleaning, display panel and wafer baking which needs particle free environment during heat treatment.
Dual Chamber Industrial Oven
Dual Chamber Industrial Drying Oven is ideal for a laboratory and industrial application needs a large number of sample treatment such as sample drying, heat treatment or thermal testing. Independent temperature controller for each chamber to set and run at different temperature according to requirement. Nevertheless it's large volume, dual heating system on upper and lower compartment with two separate heating elements and blowers provide better air circulation throughout the chamber to achieve excellent temperature uniformity and faster heat up time.
Heavy Duty Industrial Oven
Durable and Rugged Large Capacity Industrial Oven for industrial production line such as drying printed circuit panel, glass panel and stability test of electronic parts and components. Horizontal air flow with adjustable damper system on each shelf level allow to maintain optimum air circulation throughout the chamber which provides excellent temperature uniformity and operational condition
