[Histonet] Shedding biopsies

[Davis, Cassie]

Hi Diana,
RE: "In the past when we receive these samples there has been no issues cutting them.  Over the past few months there has been a tendency for these blocks to shred into fine strips when cut.  Almost like there was sand in the blocks.  Mollifex, decal, warm or cold, doesn't matter they still shred.  Getting levels is such a challenge.  I have inquired at the collection site to determine if there is a change in the process of collecting that could cause this.  I have ensured the samples are not left on gauze or something to allow them to dry out. Even blocks with lots of blood and/or mucous will shred as well as blocks with only a scanty amount present."



There was a problem a few/many years ago with a paraffin manufacture using a cardboard conveyor belt for the pellets. Apparently, small pieces of cardboard making it's way in with the paraffin. You can check your melting tub and see if there is a tan residual in the bottom this will let you know if "foreign" material may be responsible for your problem.
