Description

HM 450 Sliding Microtome

The Thermo Scientific HM450 consists of distortion-free basic construction with zero-backlash and maintenance-free cross roller bearings. The enclosed housing protects the interior feed mechanism and stepping motor.

Section thickness feed is from 0 to 10 µm in 1 µm increments, up to 20 µm in 2 µm increments, up to 60 µm in 5 µm increments, and up to 100 µm in 10 µm increments. Section thickness range is from 1 to 100 um. It provides automatic and manual feed from 0 to 100 µm. The automatic feed is independent of specimen size via reversing the sledge (can be turned off). It provides specimen retraction during knife return travel (can be turned off).

Specifications:

• Total specimen stroke: 40 mm Max.
• Sledge travel: 190 mm.
• Specimen orientation via coaxial one-hand adjustment.
• Compensation for heat extension via stepping motor: 2 µm.
• Quick change system of the specimen clamping.
• Co-axial knife angle adjustment without having to open the knife clamping.
• Integrated knife guard.

Multiple Setting Options:

• Automatic or manual sectioning
• Retraction (may be turned off)
• Three different speed settings for motorized coarse feed
