LKB Microtome Glass KnifeMaker

  • Model 7801B
  • 18.5”W x 12.25”D x 10.5”H
  • 90-day warranty 

Glass knives for ultramicrotomy are made from sheet glass supplied in selected strips of preferably 25 or 38 mm width, and 6-7 mm thick. After being cleaned in a detergent, e.g. Teepol, the strips are scored transversely in the KnifeMaker and broken off into a number of squares or rhombi, sufficient for current needs. The glass pieces are inserted in the KnifeMaker where they are scored diagonally and broken into two pieces one of which has a straight and sharp edge of high quality, provided the recommended glass quality is used and the instructions are carefully followed.

All of our equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
