High-precision laboratory vacuum drying ovens with stainless steel chambers, LCD vacuum monitoring and uniform four-wall heating for heat-sensitive materials and advanced thermal processing applications.
The Cell Lab Precision Vacuum Drying Oven Series is designed for highly efficient vacuum drying, thermal processing and low-oxygen heating applications in laboratories, research institutes and industrial environments.
Featuring a four-wall heat conduction system, intelligent PID temperature control and a high-accuracy LCD vacuum display, these vacuum ovens provide stable and uniform heating performance while reducing oxidation and contamination risks during drying.
The oven chamber is manufactured from high-quality stainless steel (SUS) and equipped with an advanced sealing system for reliable vacuum retention. The double-layer explosion-proof observation window enhances operational safety while allowing clear monitoring of samples during operation.
Available in capacities from 25L to 215L, this series is suitable for drying powders, battery materials, pharmaceuticals, chemicals, electronics, biological samples and heat-sensitive materials requiring controlled vacuum environments.
• Four-wall heating conduction system — Provides uniform heat transfer throughout the chamber for efficient and consistent drying results.
• High-precision LCD vacuum gauge — Displays vacuum degree in multiple units with stable and accurate monitoring performance.
• PID intelligent temperature controller — PT100 sensor and intelligent PID algorithm ensure precise temperature stability and rapid response.
• Explosion-proof double-layer observation window — Tempered glass with protective outer layer improves laboratory operational safety.
• Excellent vacuum sealing performance — Integrated silica gel sealing structure and inflatable port maintain stable vacuum conditions during operation.

Q1: What materials are suitable for vacuum drying?
This oven is ideal for heat-sensitive, easily oxidised or moisture-sensitive materials including powders, chemicals, pharmaceuticals and battery materials.
Q2: What is the advantage of vacuum drying?
Vacuum drying reduces oxidation risk, lowers boiling points and enables efficient drying at lower temperatures.
Q3: Does the oven include vacuum monitoring?
Yes. All models feature an LCD vacuum gauge for real-time vacuum pressure monitoring.
Q4: Is a vacuum pump included?
Vacuum pumps are optional accessories and can be supplied separately.
Q5: What safety protections are included?
The system includes over-temperature alarm protection, explosion-proof observation glass and intelligent PID temperature control.
