Small Laboratory Freeze Dryer

Laboratory freeze dryers (lyophilizers) utilize controlled vacuum sublimation to safely remove water or organic solvents from heat-sensitive biological, chemical, and pharmaceutical formulations. Engineered for university laboratories, biotechnology R&D centers, and pilot facilities, these benchtop and compact floor-standing systems deliver precise cycle repeatability, rapid batch protocol transitions, and strict adherence to analytical standards.

Condenser Temperature Options: Available in -50°C (standard aqueous solutions) and -80°C (deep freeze for low eutectic point solvents) configurations.

Capacity Range: Rated condenser ice-holding capacities from 3 kg/24h up to 4 kg/24h.

Shelf Performance: Temperatures ranging from -40°C to +60°C, supporting optional silicone oil circulation control for precise ramp rates.

Vacuum Performance: Ultimate vacuum of less than 5 Pa achieved via a direct-drive rotary vane vacuum pump.

Control Architecture: 7-inch industrial PLC touchscreen interface featuring real-time curve plotting, USB data export, and 30-segment programmable recipe storage.

Defrost Method: Rapid electric defrost and hot gas bypass systems.

Refrigeration: Hermetic Danfoss/Secop or Embraco units utilizing CFC-free mixed refrigerants (R404A/R23).

Materials of Construction: 304 stainless steel condenser chambers and shelves, complemented by food-grade silicone door sealing gaskets.

To prevent process bottlenecks and sample loss, evaluate your requirements against these four parameters:

Condenser Temperature: Select -50°C for aqueous solutions with high eutectic points; choose -80°C for samples containing organic solvents (e.g., tert-butanol, acetonitrile) or low eutectic points.

Condenser Capacity: Ensure your maximum daily sample output does not exceed 70% of the rated condenser ice-holding capacity.

Chamber Configuration: Choose the Manifold (T-type) for round-bottom flasks and ampoules, or select stoppering configurations if vials must be vacuum-sealed under a nitrogen blanket before releasing chamber vacuum.

Control Needs: Opt for silicone-fluid heated shelves with programmable ramp rates over passive electric heating plates when executing multi-step thermal treatments.

Vacuum Pump Integration: Edwards or Leybold oil-sealed rotary vane pumps, alongside dry scroll pump options for oil-free operation.

Eutectic Point Test Sensor: Resistance probe kit designed to determine critical freezing points directly inside the product vial.

PC Supervisory Software: Ethernet/RS485 communication modules supporting remote monitoring and 21 CFR Part 11 compliant audit trail logging.

Chamber Dimensions: Custom rectangular product chambers and manifold ports tailored to specific glassware volumes.

Helium Leak Detection (MSLD): Every stainless steel vacuum chamber and refrigeration loop undergoes Mass Spectrometer Leak Detection testing to maintain vacuum integrity below 10⁻⁶ Pa·m³/s.

Pressure Testing: Hydrostatic pressure testing applied to all refrigeration coils at 2.5 times operating pressure.

Factory Acceptance Testing (FAT): 72-hour continuous burn-in tests verifying temperature pull-down rates, ultimate vacuum stability, and sensor calibration accuracy.

Compliance Standards: CE certified, ISO 9001 manufacturing quality management, and RoHS compliant electrical assemblies.

Export Packaging: Fumigation-free plywood crates compliant with ISPM 15 standards, lined with moisture-barrier film and high-density shock-absorbing foam. Component protection includes separate inner carton packing for glass condensers and fragile vacuum gauges, with compressors secured on anti-vibration mounts.

Lead Times: Standard configurations ship within 15 to 20 working days, while custom voltage variants (e.g., 110V/60Hz, 220V/60Hz) require an additional 5 working days.

Warranty & Documentation: Backed by a proven manufacturing track record and a 12-month standard warranty on all mechanical and electrical components (including globally trusted Danfoss/Secop or Embraco compressors and vacuum pumps). Shipments include a comprehensive English operations manual, electrical schematics, validation guides ([Download IQ/OQ Protocol Sample]), and calibration certificates.

Troubleshooting: Supported by remote video diagnostics and spare parts dispatch within 48 hours for critical sub-assemblies.
