Unlocking Peace of Mind: The Safety Value of the VitroStash MAX Canister
In the delicate world of sample preservation in an IVF lab, maintaining optimal conditions and ensuring safety during handling are paramount. Coldstash has developed 12 large canisters (150mm diameter), designed specifically to fit in their VitroStash MAX dewar, offering significant advancements in sample storage volume and improved safety over other systems. Each canister acts as a valuable asset for safe sample manipulation when accessing specimens in an IVF cryostorage dewar.
Engineered for Stability: The Solid-Bottom Advantage
One of the most crucial safety features of the VitroStash MAX canister is its innovative design. Unlike typical canisters, it boasts a solid bottom with no openings on its base, functioning as a dedicated liquid nitrogen container. This solid construction is key to ensuring temperature stability when manipulating specimens. It allows for the safe handling of samples even when the canister is temporarily removed from the dewar. Furthermore, the "LN2 Lock™ drainless canister provides a continuous liquid nitrogen level immersion for all samples during transfer of specimens," enhancing sample security. The design also incorporates higher side vents for safer handling.
Unparalleled Stability in the Dewar's Neck
For the utmost temperature stability, the studies showed that hanging the canister from the dewar’s neck offers the best environment. When manipulated in this position, the temperature both at 3 cm (the sample point) and 7 cm from its base remained stable and did not rise above -150 degrees Centigrade at any point. ColdStash offers a HALO device that allows the user to suspend the canister in the dewar’s neck at the “sweet spot,” which maintains the canister at optimal cryogenic temperatures for extended periods. This is very beneficial when auditing specimens in an IVF lab.
In Conclusion
The new canister designed for the VitroStash MAX dewar represents a significant step forward in the safe handling and manipulation of cryogenic samples. Its solid-bottom design, capacity to maintain liquid nitrogen for extended periods outside the dewar, and the enhanced stability offered when working within the dewar's neck provide valuable peace of mind. By following recommended handling practices, especially regarding surface placement, users can confidently leverage the safety value of the VitroStash MAX canister.
