[Nhcoll-l] Tissue subsampling scissors

[Bentley, Andrew Charles]

Hi all

I am interested in knowing what others are using for subsampling tissues for tissue gift purposes in their cryo collections.  I know some people use scalpel blades but I prefer fine dissection scissors as they not only provide a finer manipulation but also (in most cases) negate having to remove the tissue from the original tube an thus avoid additional contamination possibilities.

We have been having issues however with the regular dissection scissors we have been using as frozen tissue (especially at cryo temps) causes a large amount of wear and tear (both dulling and bending) of these scissors.  So, we are considering purchasing ceramic coated tungsten carbide scissors such as these:  https://urldefense.proofpoint.com/v2/url?u=http-3A__www.medicalresources.com_shopping_proddisplay.asp-3Fcatalogid-3D18330&d=AwIFAw&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=CLFZJ3fvGSmDp7xK1dNZfh6uGV_h-8NVlo3fXNoRNzI&m=YH6kgdVNvngaC4BvStezXfuEIUtApvrk-vEQfUz0Y1M&s=hvDxlayAy9zEc7ZCtwus8kvPYWZbParjjK-l_WuSmdw&e=  - which are purported to be six times more durable than regular stainless steel varieties.  They are however VERY expensive and so, before diving in I thought I would ask around to see what others are using.

Any assistance would be greatly appreciated.
