Vessels for Cryo Storage of Sample Material

Laboratory vessels made of PFA ensure the integrity and safety of your samples even at low temperatures

The preservation of valuable samples by cryo storage is becoming more and more standard in science and research as well as in medicine. In these areas, biological sample material is frozen at sometimes very low temperatures in order to maintain the vitality of whole cells or functional cell structures over a longer period of time. Sample vials made of the fluoropolymer PFA are particularly well suited for the storage and transport of sensitive samples. PFA is an ultra-pure, high-end polymer that is stable at temperatures as low as -200°C. These properties ensure the integrity and safety of valuable samples, which has led to a widespread use of these vessels in many laboratories.

Outstanding Material Properties

• Temperature stable from -200° to +260° C: making it suitable for cryogenic storage/cryopreservation, autoclaving and hot sterilization.
• Extremely smooth surface: Thus, hydrophobic and anti-adhesive.
• No adhesion of sample material to the vessel wall: Thus, ideally suited for biomolecules.
• Free of catalyst or stabilizer additives (plasticizers and fillers): This prevents cross-contamination and ensures sample integrity.
• Good transparency: Therefore, also suitable for volume measurements.
• Chemically inert to almost all chemicals.
• Reusable after cleaning: thus, sustainable and cost-saving.

Innovative Vessel Design

AHF analysentechnik offers sample vessels in different volumes. The well considered vessel design has a rounded inner bottom, allowing the contents to be completely withdrawn again. As standard, the vessels can be closed with a screw cap. In addition, a closure tool is available that can be used to close the vials even tighter, making unintentional or unauthorized opening very difficult.

Unique Identification

On request, AHF can also laser mark PFA tubes according to your specifications. The laser marking is permanently integrated into the vessel surface. It does not wear off due to external influences, so that clear identification remains guaranteed even after many years of storage. This simplifies the allocation and management of your samples in the laboratory and helps you with quality assurance and workflow automation.
