[Histonet] block scrapers

Sakura has purpose-made scrapes. Otherwise you can use plastic scrapers from  a hardware store.

However, we moved away from scrapers and now use a heating block trimmer made for the purpose. Several vendors offer these. 


We do all block trimming at a central location so it does not need to be done at the microtome.

It is very quick and does not damage the print on the block. That is especially important for barcoded blocks.

Hi all,

My lab is in need of some tools to scrap the paraffin off the edges of the blocks after embedding. Does anyone have any recommendations for me?
