1. The vacuum environment greatly reduced the liquid point which needs to drive out, therefore the vacuum is dry may with ease apply to the heat sensitivity material.
2. For the sample that does not be dry easily, such as powder or other pellet form sample, using vacuum
3. Use more safety--Under vacuum or inertia condition, eliminate oxide completely to meet the possibility of hot explosion.
4. With dependence air cycle ordinary drying oven compare, powder form sample will not be flowed, air blows or moves. 
Though, vacuum dry technology has more numerous advantages, but it is stricter that the workmanship of drying oven compares with the relatively complex requirement for product quality with ordinary oven, our company use accurate temperature control technical and advanced manufacturing process, so our products will satisfy your needs. 
The overall vacuum cycle controller can supply programmable vacuum cycle & reduce the drying time. You can only set highest and lowest vacuum value, such as 50Pa & 900Pa, and set cycle times is 6 times, machine will auto control the vacuum & cycle times. Along with each cycle go on, humidity reduces constantly, dry speed accelerates obviously. Maximal cycle times are 99 times.
 
Summary of Functions:
1. Cuboid chamber maximizes the effective cubage. Microprocessor controller for temperature ensures a precise and reliable control.
2. Dual-layer bulletproof toughened glass door ensure absolutely clear observe on objects in chamber.
3.  Shutting extent of oven door is adjustable. Closed-cell silicon gasket ensures a high vacuum degree in oven.
4. The chamber is made of stainless steel (or wire-drawing sheet) which allows a durable service and cleaning easily.
5. Store, heating, testing and drying are all in an environment without oxygen or filled with inert gases, which ensures no oxidation.
6. Minimum heating time is over 50% less than that of traditional vacuum drying oven.

Vacuum LCD Display and Control
Vacuum drying oven adopts the digital technical control vacuum degree of simulated engineering science. "Control By Hand" becomes historical long ago. The products has full automatic LCD Dispaly controller to control electromagnetism valve. You can adjust the vacuum from 1.0E5 Pa to 1.0E-1 Pa. Control precision is 1%. Vacuum sensor is located in different position of import and export that can guarantee stabilize pressure value, not be bullied the influence that supply most steady pressure value to the operation manual.
