Labtron Cryostat Microtome offers efficient thin sectioning of frozen biological tissues. They include integrated cooling system that maintain low temperature for cryogenic sample preservation. Their cold storage feature prevents sample degradation, enhancing integrity of biological specimens. They offer customizable settings, allowing users to adjust cutting thickness for various tissue types. Our Cryostat Microtome is versatile for Immunohistochemistry, In Situ Hybridization, Electron microscopy, and tissue engineering.





Labtron’s Cryostat Microtome LCRY-A21 is specifically designed for rapid and precise slicing of frozen biological tissue samples. It is primarily used in clinical pathology, intraoperative diagnostics, and histological research to prepare ultra-thin sections of tissues. These sections are then examined under microscopes for immunohistochemistry, molecular studies, or disease diagnostics, such as cancer evaluation. Its ability to maintain ultra-low temperatures ensures sample integrity and preserves tissue morphology.
Our Cryostat Microtome LCRY-A21 integrates a semi-automatic microtome system with a high-efficiency refrigeration system, ensuring consistent sectioning at low temperatures. It offers adjustable section thickness from 1 to 100 µm, with trimming up to 600 µm. Fine controls allow users to set thickness increments based on their needs. Its blade ejector mechanism, smooth handwheel, and specimen clamp with multi-angle adjustments ensure ergonomic, accurate, and reproducible cutting, vital for histological and clinical precision.
The Cryostat Microtome LCRY-A21 uses a powerful 690 W refrigeration system with dual compressors, R4490 refrigerant, and semiconductor (Peltier) cooling elements. These systems provide temperatures as low as -60°C (±5°C) at critical points like the specimen holder and freezing shelf. Additionally, mechanical and semiconductor-based freezing points enhance temperature uniformity across the chamber. This advanced cooling setup enables stable freezing of tissue, preventing ice crystal formation that can distort cellular structures.
Cryostat Microtome LCRY-A21 offers both manual and automatic defrost modes, giving the user flexibility to clear frost build-up when necessary. The defrost cycle lasts about 15 minutes, and it helps in maintaining consistent cooling efficiency. Automated defrosting enhances convenience during extended usage while manual control gives precision when needed. This ensures that the observation window and internal chamber remain clear and effective during long procedures.
Our Cryostat Microtome LCRY-A21 is equipped with UV sterilization to minimize the risk of contamination and maintain sterile working conditions. It also has a hibernation mode, which conserves power while keeping the system in a ready state. These features are especially important in medical and research labs handling sensitive or infectious samples. The enclosed design and noise level below 70 dB(A) also ensure a safe and quiet operating environment.
