Bench-top Vacuum Freeze Dryer
Bench-top Vacuum Freeze Dryer
The Bench-top Vacuum Freeze Dryer is a compact, high-efficiency dehydration instrument engineered for laboratory-scale research, biotechnology, and small-batch sample preservation. By freezing samples and subsequently sublimating ice under a deep vacuum (<10 Pa), this equipment removes moisture while strictly preserving the biological structure and chemical composition of sensitive compounds.
Designed for benchtop placement in R&D laboratories, academic institutions, and quality control (QC) facilities, it bridges the gap between basic sample preparation and full-scale industrial production.
Condenser Temperature Options: Available in standard <= -50 deg C or high-performance <= -80 deg C cascade refrigeration models.
Ultimate Vacuum Integrity: Reaches <10 Pa for standard units and <5 Pa for high-performance systems, verified via helium leak detection.
Batch Capacity: Ice condenser capacity ranging from 3 kg/24h (BT-50) to 4 kg/24h (BT-80).
Configurations: Tailored options including Standard Bell Type (Series A), Top-Pressing Stoppering Type (Series B), and Multi-Manifold Type (Series C).
Control & Automation: Powered by PLC or Embedded Linux systems with high-definition touch screens for real-time curve monitoring.
Product Configurations & Series
We offer three distinct configurations tailored to specific container types and thermodynamic workflows:
Standard Bell Type (Series A)
Suited for flasks, ampoules, and bulk trays, featuring a transparent acrylic chamber for full visual monitoring of the sublimation process.
Top-Pressing / Stoppering Type (Series B)
Engineered specifically for pharmaceutical vials and serum bottles, equipped with a pneumatic or manual stoppering mechanism to seal vials under vacuum prior to release.
Multi-Manifold Type (Series C)
Integrated with external valves for flasks and round-bottom flasks, allowing simultaneous bulk drying on shelves and rapid drying of individual flasks.

Target Applications & Laboratory Value
Life Sciences & Biotechnology
Safe preservation of proteins, enzymes, DNA/RNA samples, antibodies, and live vaccines without thermal or structural denaturation.
Pharmaceutical R&D
Formulation development for injectable drugs, antibiotics, and multi-peptide compounds requiring extended shelf life at room temperature.
Material Science & Chemistry
Controlled synthesis of porous nanomaterials, aerogels, and recovery of high-purity organic synthesis extracts.
Food Science & Agriculture
Precise lyophilization of probiotics, nutraceutical ingredients, botanical extracts, and reference food samples for nutrient analysis.
Technical Selection Guidelines
Condenser Temperature Selection: Specify <= -50 deg C for standard aqueous solutions, general biological samples, and standard plant extracts. Select <= -80 deg C for complex formulations with low eutectic points or high sugar/solvent concentrations (e.g., cell cultures) to prevent structural collapse during primary drying.
Capacity Sizing: Calculate the total water weight per batch. Ensure the total ice mass remains under 70% of the maximum condenser capacity (kg/24h) to guarantee stable vapor capture efficiency and prevent overloading.
Solvent Compatibility Warning: Processing samples containing organic solvents (e.g., acetonitrile, methanol, acetone) requires an auxiliary cold trap or a corrosion-resistant diaphragm pump configuration to protect vacuum pump oil and refrigeration coils from rapid degradation.
Container Integration: Choose the Stoppering Model (Series B) if your protocol demands sealing pharmaceutical vials under vacuum.
Customization & Engineering Integrations
Electrical & Plug Standards: Factory-configured options for North America (NEMA 5-15P / 6-20P), UK (BS 1363), EU (Schuko), and Australia.
Sensor Upgrades: Optional high-precision Pirani vacuum sensors or PT100 resistance temperature detectors for advanced data logging.
Data Connectivity: RS485 or Ethernet communication ports supporting SCADA software integration for real-time curve tracking and historical data export (CSV/PDF).
Chamber Upgrades: 316L stainless steel condenser chambers available for enhanced resistance against corrosive acids and organic solvents.
Quality Control, Compliance & Factory Testing
Regulatory Standards: Manufactured under ISO 9001 certified quality management systems. Electrical safety strictly complies with CE Directives (Low Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU), with optional UL/CSA-compliant components available for North American markets.
Vacuum Integrity Testing: Verified via helium mass spectrometer leak detection, ensuring leak rates down to 10^(-9) Pa m^3/s.
Thermal Uniformity: Validated through 9-point temperature mapping across all shelves using calibrated thermocouple arrays (+/- 1 deg C).
Traceability Documentation: Every unit ships complete with an individual Factory Acceptance Test (FAT) report, calibration certificate, and material compliance documentation.
