BioCoool FD-1B-50+ Benchtop Freeze Dryer

Overview

The BioCoool FD-1B-50+ is a compact, benchtop freeze dryer engineered for reproducible, controlled lyophilization of heat-sensitive biological and pharmaceutical samples in research laboratories and quality control environments. It operates on the principle of sublimation under deep vacuum: frozen water is removed directly from the solid phase to vapor without passing through the liquid state, preserving structural integrity, bioactivity, and long-term stability of proteins, enzymes, vaccines, antibodies, and other labile compounds. Designed with an integrated drying chamber and stainless-steel condenser, the system ensures leak-tight operation, consistent thermal performance, and compliance with fundamental Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) expectations for process documentation and traceability.

Key Features

• Monolithic stainless-steel drying chamber—no welds or adhesive joints—minimizes leakage risk and enhances mechanical durability and cleanability.
• High-efficiency, low-noise imported compressor delivering stable −55 °C condenser temperature under no-load conditions.
• Pre-freezing capability within the condenser allows sample freezing prior to primary drying, eliminating the need for external ultra-low temperature freezers.
• Dual Pt100 temperature sensors monitor shelf and product temperatures in real time, enabling accurate process monitoring and endpoint determination.
• Graphical freeze-drying curve logging: time-stamped profiles of shelf temperature, condenser temperature, chamber pressure, and sample temperature are recorded and visualized on the built-in HMI.
• USB-based data export: all logged parameters—including curves and event timestamps—can be saved to external USB drives for offline analysis, audit preparation, or regulatory submission.
• Hot-gas defrost system provides rapid, uniform, and safe condenser defrosting without manual intervention or system downtime.
• Low-temperature drying mode enables direct condensation of volatile solvents or residual moisture at sub-zero chamber conditions, supporting specialized formulations.
• Imported gas inlet valve supports controlled backfilling with nitrogen or inert gases post-drying to prevent oxidation and ensure sterile, anaerobic storage conditions.

Sample Compatibility & Compliance

The FD-1B-50+ accommodates vial-based samples using its hydraulic or manual stoppering mechanism, making it suitable for small-batch lyophilization of pharmaceutical intermediates, diagnostic reagents, and clinical trial materials. It supports aqueous solutions, suspensions, and pastes with eutectic temperatures above −20 °C. While not certified to ISO 22000 or FDA 21 CFR Part 11 out-of-the-box, its data logging architecture—including timestamped sensor readings, user-accessible event logs, and non-volatile memory retention—provides foundational support for internal validation protocols, IQ/OQ documentation, and GLP-aligned recordkeeping. Optional accessories—including calibrated temperature probes, vacuum gauges traceable to NIST standards, and external validation thermocouples—facilitate formal qualification per ASTM F2673 or ISO 20570.

Software & Data Management

The unit features a PLC-based control system with a 7-inch resistive touchscreen HMI. All operational parameters—including setpoints, alarms, and runtime states—are configurable and persist across power cycles. The embedded firmware records up to 30 days of continuous sensor data at 10-second intervals. Exported CSV files contain columnar headers compliant with common laboratory informatics systems (e.g., LabVantage, STARLIMS), facilitating integration into electronic lab notebooks (ELNs) or LIMS platforms. Audit trail functionality includes operator login ID, parameter modification timestamps, and alarm acknowledgment logs—critical for internal quality audits and pre-submission readiness reviews.

Applications

• Stabilization of monoclonal antibodies and recombinant proteins for structural studies and formulation development.
• Preparation of reference standards and calibration materials in analytical chemistry labs.
• Lyophilization of microbial cultures, bacteriophages, and cell lysates for biobanking and functional assays.
• Routine drying of ELISA kits, PCR master mixes, and rapid diagnostic test components.
• Process development and scale-down modeling for upstream freeze-dry cycle optimization prior to pilot-scale trials.

FAQ

What types of samples are compatible with the FD-1B-50+?
Aqueous solutions, colloidal suspensions, and semi-solid pastes with eutectic temperatures ≥ −20 °C. Vials up to 22 mm diameter and 60 mm height fit standard shelves; custom trays available upon request.
Does the system support automated cycle programming?
Yes—up to 10 multi-step programs (freeze, anneal, primary drying, secondary drying, purge) can be stored and recalled via the HMI interface.
Is the vacuum pump included?
A 2 L/s domestic oil-lubricated rotary vane pump is supplied as standard; optional upgrades include oil-free scroll pumps and vacuum gauges with digital RS485 output.
Can the unit be validated for GMP use?
While not pre-certified, the FD-1B-50+ meets key design attributes required for IQ/OQ: calibrated sensors, deterministic logic control, non-volatile data storage, and full parameter logging—enabling user-led qualification per ICH Q5C and EU Annex 15 guidelines.
What maintenance is required during routine operation?
Daily: condenser defrosting and vacuum pump oil inspection. Quarterly: refrigerant pressure verification and O-ring integrity check. Annual: full sensor calibration and firmware update verification.
