Jeiotech VDC-31 Cubic Vacuum Desiccator – 35 L with Integrated Vacuum Gauge

The Jeiotech VDC-31 is designed for laboratories requiring increased vacuum storage capacity and stable low-pressure conditions.

With a generous 35-liter internal volume, it supports larger sample loads while maintaining a compact cubic footprint. The integrated vacuum gauge allows continuous pressure monitoring, ensuring vacuum performance down to 1 Torr (1.33 × 10⁻⁴ MPa) maintained for more than 72 hours at room temperature.

Cubic Geometry for Maximum Space Efficiency

Unlike round vacuum desiccators, the cubic VDC-31 offers superior internal space utilization:

• Three perforated shelves standard (expandable to five)

• Efficient vertical sample organization

• Improved storage capacity per footprint

• Stackable housing for laboratory space optimization

• Front-opening transparent door for easy access

This makes the VDC-31 particularly suitable for laboratories handling larger sample volumes or multiple trays simultaneously.

Integrated Vacuum Monitoring and Airtight Construction

All VDC models are equipped with a built-in vacuum gauge as standard.

The VDC-31 includes:

• Integrated vacuum gauge (0 to -0.1 MPa)

• Viton® 3-way valve for vacuum formation, release, and gas substitution

• Pore plug for controlled pressure equalization

• Silicone gasket for reliable greaseless sealing

• One-piece molded polycarbonate chamber to minimize leakage

These features ensure long-term vacuum stability and operational reliability.

Typical Applications

The VDC-31 is ideal for:

• Vacuum drying of hygroscopic materials

• Degassing and solvent removal

• Moisture-sensitive storage

• Sample preparation prior to analytical testing

• Chemical and pharmaceutical research

• Microbiological and material science applications

Its 35 L capacity supports medium-to-high throughput laboratory workflows.
