Expand your LN₂ tank capacity up to 3× — without buying a new dewar.

VitriStack is a color-coded, all-metal canister insert for storing vitrified embryos and oocytes. It drops into the canisters of the dewars your lab already uses, such as the MVE XC 47/11 and IC Biomedical Worthington 35, and replaces conventional cane-and-goblet loading with a high-density grid. Each carrier gets its own traceable address. The double-layer model holds 4,200+ carriers in a single standard tank, about three times what traditional loading allows.
