Frequently Asked Questions
1. Why use an aluminium vial holder instead of a standard plastic rack?
Aluminium holders from Thermo Nalgene are designed to be submerged directly into liquid nitrogen; they provide superior thermal conductivity and won't become brittle like many standard plastics at -196°C.
2. What is the purpose of a Cryonos phase separator?
A phase separator is used during LN2 transfer to vent nitrogen gas while allowing only the liquid to enter the receiving vessel, preventing dangerous splashing and ensuring a more efficient fill.
3. Are Cryonos transfer hoses compliant with safety standards?
Yes, the Cryonos transfer hoses (1.2m and 1.8m) are compliant with EN12434 and PN40 standards, making them suitable for high-pressure cryogenic liquid transfer in professional labs.
4. How many vials can the Thermo Nalgene aluminium holders accommodate?
LabFriend stocks versions designed to hold either 5 or 6 cryogenic vials, allowing for flexible batch processing or storage depending on your freezer rack configuration.
