SPI Supplies Light Microscopy Knives

Ideal for the high volume/high through put histology laboratory!


SPI Supplies offers the busy histologist or others working in light microscopy areas an outstanding range of diamond knives for light microscopy and all histology related work.

When an SPI Supplies diamond knife is ordered, there is a two step selection process, first the selection of the diamond, and then the selection of the boat.

For work on frozen specimens, to be examined by light microscopy, we recommend the diamond style of LC. The default angle is 45°, and is our recommendation for most customers. Always select cryo boat styles "D" (for dry) or "W" (for wet) depending on the type of sectioning you are doing.

For room temperature sectioning, select diamond style "LH". Depending on the diamond length, we would recommend boat style "P" or "S". Be sure to specify your boat style when ordering.

Send us your "old" knives for resharpening! We can do any brand, not just those purchased from SPI Supplies. SPI can return your worn out knives in need of resharpening, to you, just like they were the day they were new! And you can save a bundle of money over the price of new knives as well. If that should be your decision, don't return the knives until you apply for a Return Authorization number and you hear back from us with the special return number.
