Vacuum ovens with dual layer tempered glass door for clear observation. They are suitable for drying thermo-sensitive material. The short duration drying is possible for samples which doesn’t dry easily. The fully automatic electromagnetism valve controls vacuum degree which makes the vacuum degree control more exact. It adopts the digital technique of simulated engineering to control vacuum degree. The outer of the oven is made using steel sheets that are enamel and painted to prevent from corrosion.
