2.0 ml self-standing cryo tubes (100 pcs.)

Alpha is designed for the secure storage of biological material, as well as human or animal cells at extremely low temperatures, and features 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 self-standing or round bottom formats. All types feature an internal rounded base for easy sample retrieval.

Robust vial and cap – a special grade of polypropylene is used in the manufacture of all our vials, chosen for its consistent strength. This means both the vial and cap can withstand the harsh temperature of liquid nitrogen vapour phase of -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 – cap and tube are manufactured from the same material, ensuring they will shrink and expand at the same rate to maintain an equally secure seal at both room temperature and low deep freeze temperatures.
Quick open/close – 1 ¼ turns is all that is needed to securely close the cap. This is important when large numbers of vials are used as it saves time and reduces the risk of the cap not being securely closed.
Easy one-handed operation – all self-standing vials, when used with a workstation (LW3400B or LW3400R), allow vials to be unscrewed with one hand. Vertical ribs make removing the cap easier.
Clear graduations – at 100µL intervals, to aid in reading your sample volume.

Large white marking area – for sample identification and identification.
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 up to 17,000g.
Sterile – all vials are gamma irradiated to ensure absolute sterility.
Certified RNase, DNase, Pyrogen, human DNA and metal free.
Supplied in tamper-evident, resealable bags – clean and sterile.


Various cryo-boxes are available for the organized storage of samples in cryo-tubes. Further details can be found in the "Racks" section of our catalog or on our website.


The Classic Range
- designed for basic safety
The internal thread with silicone washer between cap and vial ensures a leak-proof seal at all temperatures. Designed to improve safety compared to standard screw-cap microcentrifuge tubes.
The "Classic" uses a square cross-section washer that is tightly compressed between the cap and the top of the tube wall, ensuring a secure, leak-proof seal at all temperatures.
