2.0 ml Round Bottom Cryo Tubes (100 pcs.)

Alpha is designed for the safe storage of biological material and human or animal cells at extremely low temperatures, with three ranges of CE marked cryogenic storage vials.
All products in this range are certified RNase, DNase, Pyrogen and DNA free. Alpha Laboratories cryovials are available in either a self-standing or round bottom format. All types feature an internal rounded base for easy sample retrieval.

Robust vial and closure – a special grade of polypropylene is used to manufacture all our vials, chosen for its consistent strength. This means both the vial and cap will withstand the harsh temperature of vapor phase liquid nitrogen at -196°C and the thick wall makes the vial virtually unbreakable.
Please note they are not suitable for use in the liquid phase.
Secure Seal – the cap and tube are manufactured from the same material, ensuring they will shrink and expand at the same rate to give an equally secure seal at both ambient and ultra-low temperatures.
Quick open/close – 1 ¼ turns is all that is required to securely seal the cap. This is important when large numbers of vials are being used, saving time and reducing the risk of the cap not being securely sealed.
Easy one handed operation – all self-standing vials, when used with a workstation (LW3400B or LW3400R) allow one handed unscrewing of the vials. Vertical ribs make the cap easier to remove
Clear graduations – at 100l intervals, to assist in reading your sample volume.

Large white marking area – for sample identification and labelling.
Tubes can be colour coded with a cap insert (LW3339 range) and are compatible with most storage systems. Cap inserts are available in 11 different colours. Cap inserts are not compatible with LW3439.
Only round bottom vials can be centrifuged at up to 17,000 x g.
Sterile – all vials are gamma irradiated to ensure absolute sterility.
Certified free from RNase, DNase, Pyrogen, human DNA and metals
Supplied in tamper evident, re-sealable bags – clean and sterile.
