Diamond knives for low temperature EM and LM applications

Available for sale in U.S.A. only


cryo 25°

The 25° angle of the cryo 25° diamond knife produces sections of frozen hydrated specimens with the least compression and the best structural preservation possible. It is recommended that sectioning be done in a low humidity glove box and the sections should be attached by electrostatic force. Section thicknesses range from 30 to 150nm. Triangular holder. Blade width, 3.0mm.

cryo 35°

The cryo 35° knife has demonstrated its usefulness as a standard knife for the low temperature sectioning of polymers, rubber, paints, etc. The 35° angle represents a balanced compromise between section quality and durability. Two styles (wet and dry) are available. Mounted in the triangular holder cryo 35° is suitable for dry cryo sectioning. The 35° knife mounted in the trough are used for sectioning with fluids such as a DMSO/water mixture. Section thicknesses range 30 – 300nm. Triangular holder (dry) or small boat (wet). Blade widths 1.5 to 4.0mm.

cryo 45°

The cryo 45° knife is well suited for routine cryo sectioning. Like the cryo 35° it is available in two styles (wet and dry). Mounted in the triangular holder cryo 45° is suitable for dry cryo sectioning. The 45° knife mounted in the trough are used for sectioning with fluids such as a DMSO/water mixture. Section thicknesses range 30 to 300nm. Triangular holder (dry) or small boat (wet). Blade widths 1.5 to 4.0mm.

DiATOME® Cleaning Procedure for Cryo Knives

This procedure serves for the cleaning of our cryo immuno and cryo 25° knives. We are at your disposal for any further assistance you might require.

1. Remove the knife stage from the cryo
chamber, leave the knives in the stage,
wash under tap water for warming up.
2. Bevel a polystyrene stick with a
perfectly clean razor blade.
3. Clean the knife with 50% ethanol,
keep wet.
     
 
4. Rinse with 100% ethanol. 5. Dry with a dustblower or canned air.
