Vial holder for freeze drying

简介

Simple clip for connecting up to 8 vials together to allow them to be easily fished out of the liquid nitrogen and inserted into the freeze dryer. Allows access to the vial caps to allow them to be compressed shut in the dryer and allows contact of the vials with the metal shelves in the freeze dryer allowing thermal transfer. I've printed this in PLA (maybe not the best but its all I have at hand) and it survives quite a few cycles of clipping and unclipping before breaking (although this may also depend upon temperature). Designed to work with vials with a outer neck diameter of around 15.5 mm diameter and ≥ 4 mm depth at its waist and a lip on top with an outer diameter > 16 mm.
