Floor Freeze Dryer

Freeze dryer (lyophilizer) for vacuum sublimation drying of biological and pharmaceutical samples. Features: Secop compressor (international brand) with hybrid refrigeration technology, ensuring low-temperature stability and environmental compliance. 7-inch color LCD touchscreen with user-friendly HMI, lock screen function, and optional remote control via PC/mobile. Industrial-grade embedded OS with isolated power supply design (strong/weak current separation) for enhanced safety. Auto-save function for freeze-drying parameters, supporting data review, export (USB), deletion, and anti-loss protection. Transparent high-pressure corrosion-resistant PE chamber (460mm height, one-piece injection molding) for real-time material observation. Stainless steel vacuum line with KF25 quick-connect clamp; corrosion and low-temperature resistant. Vacuum pump delay start (activates below set temperature) to extend lifespan. Real-time display of vacuum level, cold trap/material temperatures, and freeze-drying curves; supports multi-curve storage and USB data extraction. Vacuum alarm, power-off auto-inflation (prevents moisture ingress), and inert gas filling port. One-click auxiliary heating/defrost for rapid recovery. Axial cooling fan with dual-ball imported bearings for ultra-stable operation and extended durability. Magnetic maintenance panel for easy cleaning and dust management. Automated reminders for pump oil replacement and system upkeep based on operational hours. Biologics: Vaccines, antibodies, proteins, peptides, enzymes, hormones, and other highly temperature-sensitive active substances—freeze-drying is the gold standard process for maintaining their long-term activity. Antibiotics: Such as penicillins and cephalosporins, which can address the issue of potency decline in humid and hot environments. Diagnostic reagents: Products that require the preservation of activity, such as enzyme-linked immunosorbent assay (ELISA) kits and nucleic acid detection kits. Freeze-drying stabilizes drugs at the molecular level through a dual mechanism of water removal and low-temperature processing: Inhibiting hydrolysis reactions: Water serves as both a medium and a reactant in many degradation reactions. Freeze-drying reduces water content to 1%–3%, physically blocking chemical degradation pathways such as hydrolysis and oxidation, thereby preserving the drug’s chemical integrity. Inhibits microbial growth: Extremely low water activity creates an environment where microorganisms cannot survive, preventing biological spoilage. Protects heat-sensitive molecular structures: Processing at low temperatures throughout (typically below -40°C) prevents structural damage—such as protein denaturation and antibody inactivation—caused by high temperatures. Forms a stable physical form: Freeze-drying produces a loose, porous, sponge-like “cake” with a large specific surface area and stable physicochemical properties, capable of maintaining efficacy for several years at room temperature. Rapid Rehydration: The porous structure allows for complete rehydration within seconds upon contact with a solvent, restoring the original therapeutic efficacy. Equipment Performance and Compliance: Do core parameters—such as cold trap temperature, shelf uniformity (temperature difference ≤ ±1°C), and vacuum level—meet standards? In the pharmaceutical sector, confirm that IQ/OQ/PQ validation documents are provided and comply with GMP/FDA requirements.
