This page of the SPI Supplies website is devoted to the subject of ultramicrotomy, not the ultramicrotome itself, but the diamond knifes, and the products needed to care for an expensive high precision diamond knife. First and foremost we want to publicize the SPI Supplies® Brand of diamond knives.

User after use tells us that when it comes to sectioning and ease of use, no knife in the world is better than the SPI Supplies knives. Now we are not saying that the SPI Supplies knives are better than anyone else's, but we are saying that they are indistinguishable in performance from knives that seem to carry prices that are far higher. Of course, sophisticated customers realize that when the US dollar is low and European currencies are strong and high, what makes the European made knives more expensive has nothing to do with productions methods or manufacturing technology, it has only to do with exchange rates!

We also want to point out that one needs to give a lot of thought about the maintenance of the knife, and how it is cleaned after use. The diamond knife cleaner is designed to prolong the useful lifetime of your diamond knife.

Last but not least, we want to call attention to our products for those who work with glass knives, perhaps to face off a black before turning to the much more expensive diamond knife for the thin sectioning. The Ralph knife maker is used all over the world for making glass knives for histology and the Messer Type C Sunkay Knife Maker is designed for making the ultimate glass knife for ultramicrotomy (e.g. TEM thin sections). The quality of the SPI Supplies brand of microtome knife glass is second to no one's and is certainly better than some other less known brands of glass.
