Cryostat Microtome - Frozen Section Cryostat - Chamber to -50°C - 0.5-100 µm Sections

The Master Science Cryostat Microtome freezes and sections fresh tissue for rapid examination. A microcomputer control panel sits on top, the freezing chamber with the microtome is in the middle, and the compressor unit is housed below.

Dual compressors cool five points separately: the chamber, freezing shelf, knife holder, sample chuck and tissue presser. Chamber and chuck temperatures reach -50 °C, and an added semiconductor stage takes the fast-freeze position to -60 °C. Sections are cut from 0.5 to 100 µm.

Common Problems and How This Cryostat Helps

How the Master Science Cryostat Microtome handles frozen-section challenges:

• Tissue freezing too slowly: semiconductor stage reaches -60 °C.
• Sections curling or sticking: anti-adhesive flattening plate.
• Condensation on the window: heated glass door.
• Energy use between cases: sleep mode with fast recovery.
