JEC Tori Siebel 5L Liquid Nitrogen Dewar Vessel JEC-5L

The JEC Tori Siebel 5L Liquid Nitrogen Dewar Vessel (Model JEC-5L) is a cryogenic storage container designed for secure containment of liquid nitrogen with controlled evaporation rates. Its vented cap is non-hermetic, allowing continuous evaporation at approximately 4% per day under ambient 15℃ conditions, suitable for cryogenic applications in molecular diagnostics and bioprocessing.

Key Specifications:

• Capacity: 5 liters liquid nitrogen volume
• Neck Diameter: 19 mm facilitating insertion of cryogenic tools
• Outer Diameter: 260 mm and height of 510 mm for benchtop use
• Weight: Lightweight at 3.40 kg for easy handling in lab environments
• Seal: Non-tight cap which prevents pressure buildup, optimized for vapor release
• Storage Orientation: Designed for vertical storage only; internal vessel stabilized by neck support, horizontal placement not recommended to avoid liquid nitrogen spillage or damage

This liquid nitrogen Dewar flask is critical for biotechnology laboratories requiring long-term cryogenic preservation, biomanufacturing workflows, and live-cell imaging sample storage. The durable design with attention to evaporation rates and handling guidelines makes it widely adopted in synthetic biology and molecular biology research requiring precise cryogenic environment maintenance.

Sold used, the unit shows minor surface blemishes but remains fully functional for biotechnology and medical research applications. Ideal for labs conducting gene editing, molecular diagnostics, or bioprocessing needing reliable cryogenic storage vessels.

This equipment is essential for researchers focusing on cryogenic sample preservation integral to molecular cloning workflows and biopharmaceutical production pipelines.
