Liquid Withdrawal Device (LWD)

For Liquid Nitrogen LD25, LD35 and LD50 Dewars 

 The Liquid Withdrawal Device (LWD) provides convenient pressure transfers of liquid nitrogen from LD25, LD35 and LD50 Dewars. The device clamps directly to the special neck flange that is found under the plastic trim collar around the neck of these containers. 

Enhanced Safety Benefits for Cryogenic Operations

Our liquid nitrogen withdrawal device eliminates the need for manual access to the internal freezer, which significantly reduces occupational cryogenic hazards. By automating liquid nitrogen dispensing, this cryogenic liquid withdrawal system protects laboratory personnel. Some advantages include:

• Reduced exposure: Each device eliminates close-proximity contact with extremely cold materials, protecting staff from cryogenic burns and frostbite.
• Controlled pressure management: The equipment helps prevent sudden vapor release and boil-off, which are major sources of worker injury.
• Regulatory compliance: The investment demonstrates a commitment to occupational safety standards and employee well-being.

Seamless Integration With Existing Freezer Systems

This LN2 dispensing system offers straightforward compatibility, designed to work seamlessly with your existing cryogenic infrastructure. The implementation offers many benefits, including:

• Minimal downtime: The installation requires minimal disruption with no system shutdown or sample transfer.
• Cost-effective upgrade: Retrofit existing liquid nitrogen handling equipment to avoid costly replacement expenses.
• Flexible deployment: Many biobanks implement this liquid nitrogen dispensing equipment incrementally to test the integration before a facility-wide adoption.

Liquid Withdrawal Devices FAQs

Learn more about our liquid withdrawal devices.

How much time does LWD save compared to manual withdrawal?

Manual liquid nitrogen withdrawal is a labor-intensive process that requires safety preparation, extraction, monitoring and cleanup. Automated withdrawal systems streamline these steps, which significantly reduces the time per freezer and frees your technical staff for higher-value laboratory activities.

For facilities maintaining multiple freezers on weekly refilling schedules, the time savings translate to substantial annual labor cost reductions.

Is the LWD compatible with my existing cryopreservation equipment?

Yes, the LWD is engineered specifically for LD25, LD35 and LD50 dewars. At IC Biomedical, our straightforward retrofit process allows biorepositories to upgrade without disrupting your sample storage. We can offer guidance on testing the device at your facility and implementing a smooth rollout.

What safety advantages does the LWD provide?

By automating extraction, this device eliminates hazardous manual processes. The controlled pressure management prevents sudden boil-off and vapor release, which can expose workers to oxygen-deficient atmospheres and cause cryogenic burns. As a result, organizations can enhance their operational safety and reduce the risk of injury.

Will LWD protect samples during maintenance operations?

Each low-pressure liquid nitrogen transfer maintains consistent temperatures throughout the withdrawal. Rapid fill times minimize the freezer lid-open duration, protecting the sample integrity. Controlled dispensing ensures stable cryogenic conditions, which are crucial for biobanking applications where sample viability relies on uninterrupted storage at ultra-low temperatures.
