Lab-Scale Vacuum Lyophilizer for Biological Samples The lab-scale vacuum lyophilizer is a compact, high-precision instrument designed for research institutions, biotech labs, and universities, used to preserve biological samples like cells, proteins, enzymes, and tissue sections. With a small footprint (600×500×800mm), it fits easily in fume hoods or cleanrooms. Its core components include a -80℃ ultra-low temperature cold trap (to capture water vapor) and a rotary vane vacuum pump (achieving ≤1Pa vacuum degree), ensuring rapid sublimation without sample denaturation. The touchscreen control system allows real-time monitoring of shelf temperature, chamber pressure, and lyophilization time, with data export via USB for experiment records. It supports batch processing of 1-5L samples in vials, ampoules, or petri dishes, with a freeze-drying cycle of 8-24 hours. A key feature is its programmable pre-freezing function, which prevents ice crystal formation that damages cell membranes—tests show it maintains 95% cell viability for stem cell samples, 20% higher than conventional freezers. Equipped with a defrosting system and easy-to-clean chamber, it simplifies maintenance and ensures sample purity, making it indispensable for life science research.
