Foam Cryo Dewars & Liquid Nitrogen Pitchers
The Safer Alternative to Glass: Our range of foam dewar liquid nitrogen vessels, including the PELCO foam cryo pitcher, offers a lightweight, shatterproof cryogenic vessel solution. Featuring low thermal mass foam, these containers minimize boil-off and are ideal LN2 transfer vessels for Vitrobot dewar filling and clipping station LN2 maintenance.
Material: Chemically Inert Closed-Cell Foam
Safety: Shatterproof & Frost-Resistant
Efficiency: Low Thermal Mass (Less Boil-off)
Available in 130ml, 500ml, 800ml, 1000ml & 1800ml
PELCO® Foam Cryo Pitcher: Precision Pouring
The PELCO foam cryo pitcher is specifically engineered for precision nitrogen pouring. Unlike standard glass dewars which can be heavy and slippery, this 1000ml cryo pitcher features an easy-grip LN2 handle and a dedicated pour spout. It is the perfect tool for grid clipping LN2 transfer and topping off small reservoirs like the Vitrobot dewar without spillage.
The unit includes a bi-directional lid that can be rotated to cover the spout (reducing evaporation) or open it for pouring, making it a superior glass dewar alternative.
Foam Cryo Cups & Vessels
For general benchtop cryo cup applications, our foam cryo cup series (available in 500ml, 800ml, and 1400ml) provides a convenient protruding handle design for safe handling. We also offer specialty sizes like the mini cryo vessel 130ml for small samples and the tall cryo vessel 1800ml for longer immersion tasks.
Material Advantages
Manufactured from a patented chemical inert foam, these vessels are durable foam construction that will not leak or degrade over time. Key benefits include:
- Frost-Resistant Cryogenic: The outer surface stays dry and easy to hold, unlike glass which accumulates thick frost.
- Low Thermal Mass: The vessel cools down instantly, resulting in significantly less LN2 boil-off during filling compared to glass or ceramic.
- Safety: A true polystyrene dewar replacement that is robust and won't shatter if dropped.

Frequently Asked Questions
1. Is this better than a glass dewar?
For transfer and short-term benchtop use, yes. The cryogenic foam vessel is lighter, shatterproof, and has a lower thermal mass, meaning less liquid nitrogen is wasted cooling down the container itself.
2. Can I use the pitcher for the Vitrobot?
Yes, the PELCO foam cryo pitcher is the ideal tool for Vitrobot dewar filling. The spout allows for controlled pouring into the small annular gap of the Vitrobot coolant container without splashing.
3. Will the foam degrade over time?
No. These are made from a specialized cross-linked, closed-cell foam that is chemically inert and designed for repeated exposure to liquid nitrogen. It is a durable, long-term cost-effective cryogenic storage solution.
4. Does it come with a lid?
The Cryo Pitcher models (500ml and 1000ml) come with a specialized bi-directional lid. The Cryo Cups and Vessels typically come with a plug-style lid or cover depending on the specific model.
5. Is it safe to touch the outside?
Yes. The foam acts as an excellent insulator. While the inside is at -196°C, the outside remains safe to touch and relatively frost-free, unlike glass or metal dewars.
