Life Science Diamond Knives
SPI offers the electron microscopist and ultramicrotomists the ultimate in Life Science Diamond Knives. On a "blind" test, it is just not possible to tell even the slightest difference between the SPI Supplies Life Science Diamond Knife and those carrying a "name brand" and costing far more.
When an SPI Supplies life science diamond knife is ordered, unless otherwise specified, will be shipped with boat Style "S". Unless otherwise specified, it will also be shipped with the "default" angle of 45°. Please be sure to read our section on
Other life science options are as follows:
Cryomicrotomy wet style Diamond Style CW 45° standard: For use with frozen specimens sectioned wet with liquids like ethylene glycol BE SURE TO SELECT RECOMMENDED BOAT STYLE "W".
Cryomicrotomy dry Diamond Style CD 45° standard: For use with frozen specimens sectioned dry BE SURE TO SELECT BOAT STYLE "D".
Thick/Thin sectioning Diamond Style TS 55° standard: For thick sections or alternating thick/thin sections Be sure to select boat Style "TS"
Each SPI Supplies Life Science Diamond knife is rigorously inspected before final package sealing and shipping. This testing involves a TEM inspection of sections cut with the new knife because SPI wants to make sure that we ourselves are conducting a rigorous quality assurance program on our own end and are not going to be relying on our customers to serve as our quality control laboratory!
