Lightweight, Nearly Unbreakable Vacuum Desiccator with Airtight Silicone O-Ring Seal (250 mm)
Thermo Scientific™ Nalgene™ Transparent Polycarbonate Classic Design Desiccator is a durable, cost-effective alternative to traditional glass desiccators, designed for safe moisture-free storage and vacuum drying applications. Constructed from high-strength transparent polycarbonate, this classic desiccator provides excellent visibility, superior impact resistance, and reliable vacuum performance without the need for vacuum grease.
A silicone O-ring ensures an airtight seal, reducing contamination risks associated with grease while maintaining a stable vacuum for extended periods. Suitable for both vacuum and non-vacuum conditions, this desiccator is ideal for laboratories requiring a lightweight, nearly unbreakable solution for drying hygroscopic samples and protecting sensitive materials from humidity.
Key Features and Benefits
Airtight Seal Without Vacuum Grease
Silicone O-ring provides a secure seal, eliminating the need for vacuum grease that can introduce contaminants into laboratory workflows.
Transparent Polycarbonate Construction
Lightweight and nearly unbreakable, offering excellent safety and durability compared with glass desiccators.
Suitable for Full Vacuum and Non-Vacuum Use
Designed to withstand full vacuum conditions safely when used according to instructions.
- Holds vacuum of 28 in.Hg (71.1 cm) for up to 24 hours
Wide Base for Superior Stability
Broad footprint enhances stability on laboratory benches and in drying workstations.
Convenient Vacuum Ports on Cover and Base
Ports on both the cover and base provide flexible vacuum connection options.
Replaceable Stopcock Assembly
Removable stopcock can be replaced or removed entirely, with a cap included if the port is not used.
Cost-Effective Alternative to Glass
Similar dimensions to glass desiccators but more economical and resistant to shattering or implosion.
