GMP Model Stainless Steel Precision Laboratory Vacuum Oven (TI-VO Series)
GMP Model Stainless Steel Vacuum Oven
The Tempo Instruments Precision Laboratory Vacuum Oven is designed for moisture removal, solvent evaporation, and heat-sensitive material drying under reduced atmospheric pressure. Heavy SS 316 hermetically sealed vacuum chamber with high-grade silicone gasket door, toughened safety viewing window, direct conductive shelf heating, and optional 7-inch color touchscreen PLC with 21 CFR Part 11 audit compliance.
Validation Packages & Auxiliary Hardware
Add mandatory validation documentation, vacuum pumps, and cold traps for your facility.
IQ, OQ & PQ Validation Documentation
Full operational qualification binder with calibrated PT-100 temperature and Pirani vacuum gauge trace certificates.
Rotary Vane / PTFE Diaphragm Vacuum Pump
Direct-drive oil-sealed double-stage rotary pump or chemically resistant PTFE diaphragm pump for solvents.
Sub-Zero Refrigerated Cold Trap Condenser
Protects the vacuum pump by trapping evaporated solvent vapors at temperatures down to -40°C.
Low-Temperature Vacuum Evaporation & Drying Technology
TEMPO Instruments Vacuum Ovens enable rapid drying of active pharmaceutical ingredients (APIs), heat-sensitive organic compounds, electronic components, and powder samples by reducing the boiling point of liquids under high vacuum conditions up to 760 mmHg.

Vacuum Oven Operation & Purging Walkthrough
Frequently Asked Questions & Vacuum Safety
Vacuum drying significantly reduces the boiling point of solvents and water, permitting rapid moisture evaporation at lower temperatures. This prevents thermal degradation, active ingredient breakdown, and oxidation under inert nitrogen gas backfill.
For non-corrosive aqueous applications, a double-stage oil-sealed rotary vane vacuum pump is ideal. For aggressive organic solvents or acidic vapours, a chemically resistant PTFE diaphragm pump along with a sub-zero cold trap is recommended.
