HH-3658C Computerized Cryostat & Paraffin Microtome
Product Introduction
The HH-3658C Computerized Cryostat & Paraffin Microtome is a dual-purpose tissue sectioning system that integrates the HHQ-3658 Computerized Microtome with the HH-III Intelligent Rapid Freezing System. Designed for both rapid frozen sectioning and routine paraffin sectioning, it provides laboratories with two essential histology techniques in one compact instrument.
Built with advanced nanomaterial technology, an intelligent LCD control system, and a high-precision stepper motor, the HH-3658C offers accurate thickness adjustment, stable cutting performance, and user-friendly operation. Automatic temperature control, rapid refrigeration recovery, automatic defrost, and quick-change specimen holders significantly improve laboratory efficiency while ensuring high-quality tissue sections for pathology and histological analysis.

Features
•   Dual-purpose design for frozen sections and paraffin sections.
•  Combines a computerized precision microtome with an intelligent rapid freezing system.
•   Intelligent LCD display for intuitive operation and real-time status monitoring.
•   Displays preset temperature and actual operating temperature.
• Automatic temperature control with intelligent constant-temperature regulation.
•   Automatic alarm and automatic defrost functions.
•   Rapid cold-stage defrost allows quick tissue replacement.
•   Refrigeration automatically resumes after defrosting.
•   High-precision stepper motor ensures smooth and accurate sectioning.
•   Patented trimming adjustment allows thickness setting via control panel or fine handwheel.
•  Quick-change specimen holder for easy switching between frozen and paraffin applications.
•   Excellent section quality suitable for routine and intraoperative pathology.

Working Principle
The HH-3658C combines precision mechanical sectioning with rapid cryogenic cooling. For frozen section applications, the intelligent refrigeration system rapidly cools the specimen and knife to the required cutting temperature while maintaining stable thermal conditions throughout the procedure.
The computerized microtome uses a precision stepper motor to accurately control specimen feed and section thickness. Users can perform routine sectioning or trimming using either the electronic control panel or the fine adjustment handwheel. Automatic defrost and rapid refrigeration recovery reduce downtime, enabling continuous, efficient tissue processing.
