Laboratory Desiccators and Vacuum Desiccators
Labman Instruments is official distributor for Jeiotech desiccators and vacuum desiccators for Europe.
Secure and Controlled Sample Storage with Desiccators
Desiccators are essential laboratory solutions for protecting moisture-sensitive materials under controlled storage conditions. By maintaining a dry internal environment, they prevent degradation, contamination, and instability caused by ambient humidity. Depending on the required level of humidity control and drying performance, laboratories can choose between standard atmospheric desiccators, vacuum desiccators for accelerated moisture removal under reduced pressure, or electronic auto-desiccator cabinets with active humidity regulation.
The Jeiotech portfolio offers reliable and durable solutions for research laboratories, quality control environments, electronics manufacturing, and industrial applications. These systems are suitable for the storage of electronic components, chemical reagents, optical instruments, reference standards, and other hygroscopic materials. With robust construction, transparent viewing panels, airtight sealing systems, and precise humidity management options, Jeiotech desiccators ensure stable, reproducible, and contamination-free storage environments for critical materials.
Vacuum Desiccators
Vacuum desiccators are the optimal solution for rapid moisture removal under reduced pressure. By evacuating air down to 1 Torr, samples can be efficiently dried and protected from humidity-sensitive degradation. These units are ideal for hygroscopic chemicals, electronic components and research samples requiring controlled vacuum conditions. Choose between round, cubic or cylindrical formats depending on capacity and workflow needs.

Frequently asked questions about desiccators
What is the difference between a desiccator and a vacuum desiccator?
A standard desiccator maintains a low-humidity environment using desiccant material, while a vacuum desiccator uses a vacuum pump to remove air and moisture completely. Vacuum desiccators offer more effective protection for highly sensitive samples.
What is the difference between a vacuum desiccator and an auto desiccator?
A vacuum desiccator removes moisture by evacuating air and creating reduced pressure, making it ideal for rapid drying or solvent removal. An auto desiccator, by contrast, does not use a vacuum pump. Instead, it actively regulates the internal humidity to a defined setpoint (for example 20–60% RH), making it better suited for long-term controlled storage of moisture-sensitive samples. Vacuum models are typically used for process drying, while auto desiccators are designed for stable, repeatable humidity control.
Which desiccator is best for storing light-sensitive samples?
UV-blocking models such as the VDR-UG, VDP-UG, or VDC-U series are designed for light-sensitive materials. They feature UV-resistant polycarbonate windows that prevent light degradation during storage.
How long can vacuum be maintained in these desiccators?
Jeiotech vacuum models can maintain a vacuum of 1 Torr for up to 72 hours, thanks to their high-quality sealing and leak-resistant construction.
Do I need a vacuum pump to use a vacuum desiccator?
Yes, an external vacuum pump is required to evacuate air from the chamber. Some models also support inert gas purging via a 3-way valve system.
Are your desiccators stackable?
Yes, many models such as the VDR and VDC series feature stackable designs, which save bench space and increase storage capacity in compact labs.
Can I monitor humidity levels inside the desiccator?
Standard non-vacuum models (SDC series) are equipped with built-in hygrometers. Vacuum models can also be fitted with optional vacuum gauges or external sensors.
When should I choose an auto desiccator instead of a standard desiccator cabinet?
A standard desiccator cabinet relies on passive desiccants such as silica gel, which require regular replacement and do not provide precise humidity control. An auto desiccator electronically controls and maintains the internal humidity, offering greater stability and reduced maintenance. It is recommended when consistent humidity levels are critical, such as for electronic components, reference standards, hygroscopic chemicals, or long-term laboratory storage.
