1) 28 segments temperature profile programmable, 2) Maximum Heating Rate: 4~6C/min, 3) +/- 5C accuracy - details see: https://www.machineto.com/400c-high-temp-vacuum-drying-oven-with-vacuum-system-25l-10297439

The JY-25VO series vacuum drying oven is CE certified. It can be heated up to 300-400C. A 50-500ml flow meter is installed in the front panel for user to simply control and create a gas environment in the chamber. All necessary accessories are in the package including vacuum pump, hoses, etc.

Features of Vacuum Drying Oven:

1) Radiant warm wall heating system provides optimal uniformity and conserves chamber space for drying, curing, vacuum embedding, and plating applications.

2) 3" (7.6 cm) glass wool insulation prevents heat loss from working chamber

3) Silicone door gasket and positive latch door maintain seal at all vacuum levels

4) Exclusive polycarbonate safety shield protects door glass

5) 28 segments programmable digital temperature controller with +/- 1.5°C accuracy

6) Maximum Heating Rate: 4~6 ºC/min

7) Vacuum fittings require .25" (6.35 mm) I.D. tubing

8) Easy-to-clean #304 stainless steel chamber interior

9) 2 stainless steel shelves were included for immediate use

10) Vacuum and air lines constructed with corrosion-resistant stainless steel tubing for optimum chamber cleanliness and long term performance.
