Jeiotech VDR-20 Round Vacuum Desiccator – 6L Transparent Model

The Jeiotech VDR-20 is part of the Round Type Vacuum Desiccator series, engineered for reliable dehumidification in vacuum state. With a maximum permissible vacuum of 1.33 × 10⁻⁴ MPa (1 Torr) maintained for up to 72 hours, it is ideal for sensitive samples requiring moisture removal without heat exposure.

Its compact 6L internal volume makes it particularly suitable for small batch laboratory applications, routine drying, and vacuum storage of hygroscopic materials.

Round Type Design – Compact and Laboratory Friendly

The round geometry ensures uniform stress distribution under vacuum and provides a highly space-efficient footprint. The VDR-20 features:

• Transparent polycarbonate (PC) construction for full visual inspection

• Solid integral molded body to minimize leakage

• UV-protection version available (U model)

• Dedicated PP desiccant tray included

• Useful 3-way valve for vacuum formation, removal, and gas substitution

Unlike the cubic VDC series, the VDR models prioritize compactness and lightweight handling.

Vacuum Performance up to 1 Torr

The VDR-20 maintains vacuum down to 1 Torr (1.33 × 10⁻⁴ MPa), making it suitable for:

• Moisture removal under reduced pressure

• Drying of hygroscopic compounds

• Sample stabilization prior to analysis

• Vacuum storage applications

This specific version is delivered without vacuum gauge, allowing laboratories to use external vacuum monitoring systems where required.

For applications requiring integrated monitoring, the VDR-20G (G-type) is available with built-in vacuum gauge.

Transparent and Durable Construction

The VDR-20 is manufactured from high-clarity polycarbonate (PC):

• Shatter-resistant

• Lightweight

• Chemically resistant

• Easy to clean

• RoHS compliant

The integral molded structure prevents warping even under repeated vacuum cycles.
