Microm HM 450 Sliding Microtome

Microm HM 450 Sliding Microtome

Cambridge ID #: 22758

Description:

The sliding microtome HM 450 from Thermo Scientific is a highly efficient instrument with specimen retraction during return travel. It can be used for sectioning paraffin in the routine lab. The main applications are in human and veterinary medicine. Moreover, the sliding microtome can be used for the specimen preparation in the medical and industrial research. Large and hard specimens from pharmaceuticals industry or from quality assurance labs can also be sectioned. The cross roller bearings on sledge and block allow non-tiring working and a smooth sliding movement with optimal stability. The HM 450 will cut sections from 0 µm to 100 µm. The specimen clamping can be moved up and downwards via the two arrow-shaped coarse feed buttons on the left side of the instrument. This way, specimen and knife edge distance can be adjusted quickly. The knife carrier is designed so the knives can be easily clamped in place and adjusted. The coaxial specimen orientation allows orientation with one hand.

Krumdieck MD6000 Live Tissue Microtome

Krumdieck MD6000 Live Tissue Microtome

Cambridge ID #: 18864

Description:

The instrument provides samples of uniform and reproducible thickness, minimizes damage to surfaces of slices and thereby eliminates the main sources of error in tissue slice work. Slices from approximately 100 to 500 microns in thickness can be prepared at a maximum rate of one slice every 3 to 4 seconds. The slicer operates submerged in a buffer selected by the operator as most appropriate in terms of composition, tonicity, pH, temperature, oxygenation and lubricating properties to maintain the viability of the tissues being sectioned. The microtome and the reservoir with the glass trap are sterilizable to allow the preparation of aseptic slices suitable for prolonged organ culture. The actual slicing is done by a rapidly reciprocating disposable blade oscillating at 1000 to 2500 rpm driven by a motor that also powers the impeller.  The tissue slicer contains a cooling block which allows the temperature of the buffer solution in the slicer’s reservoir to be maintained.
