BIOCOOL FD-1E-110+ Laboratory Freeze Dryer

Overview

The BIOCOOL FD-1E-110+ is a high-performance, manifold-type laboratory freeze dryer engineered for reproducible lyophilization of heat-sensitive biological, pharmaceutical, and chemical samples containing volatile organic solvents. It operates on the fundamental principle of sublimation—removing water or solvent from frozen samples under deep vacuum while maintaining product integrity through precise thermal control. Unlike standard freeze dryers limited to aqueous systems, the FD-1E-110+ integrates a −110 °C ultra-low temperature condenser capable of efficiently trapping low-boiling-point organic solvents (e.g., acetone, ethanol, ethyl acetate) at concentrations up to 95 vol%, thereby preventing solvent backstreaming, pump oil contamination, and system corrosion. Its monolithic drying chamber eliminates seam-related leakage risks, and the integrated pre-freezing function enables direct sample freezing within the condenser—reducing handling steps and minimizing thermal shock.

Key Features

• Ultra-low temperature condenser (−110 °C, empty load) with high-efficiency capture of volatile organic solvents
• Manifold configuration with independent valve-controlled ports for simultaneous drying of multiple external flasks (e.g., serum bottles, scintillation vials)
• Patented airflow-guiding cylinder design to enhance vapor flow uniformity and reduce primary drying time
• Dual Pt100 sample temperature probes for real-time monitoring and logging of product thermodynamics during lyophilization
• PLC-based control system with 7-inch touchscreen HMI supporting programmable freeze-drying cycles, curve visualization, and parameter recall
• Pulse-controlled inert gas backfill system with factory-installed solenoid valves for nitrogen or argon purging post-drying
• Automatic defrost cycle with condensate drainage management to minimize downtime between batches
• Hermetically sealed drying chamber fabricated from seamless stainless steel (AISI 304), pressure-tested to 0.2 MPa

Sample Compatibility & Compliance

The FD-1E-110+ accommodates a broad range of sample formats including liquid solutions, suspensions, pastes, and gels with eutectic temperatures above −20 °C. It supports lyophilization of organic-aqueous mixtures commonly encountered in small-molecule API processing, natural product extraction, and analytical reference standard preparation. The system complies with general laboratory safety requirements per IEC 61010-1 and meets mechanical integrity benchmarks aligned with ISO 22870 (Good Lyophilization Practice). While not certified for GMP production, its architecture supports audit-ready operation when paired with optional accessories such as GLP-compliant data loggers, electronic signatures, and 21 CFR Part 11–enabled software modules (available upon request).

Software & Data Management

The embedded control interface records time-stamped process data—including shelf/condenser temperature, chamber pressure, and sample thermocouple readings—at user-defined intervals (1–60 s). All freeze-drying profiles and historical runs are stored internally and exportable via USB flash drive in CSV format for offline analysis. Curve plotting functionality allows overlay comparison of multiple cycles, facilitating optimization of hold times, ramp rates, and pressure setpoints. Optional firmware upgrades support audit trail generation, user access levels (admin/operator), and password-protected parameter modification—features critical for method validation and regulatory documentation.

Applications

• Lyophilization of organic-solvent-based extracts (e.g., plant alkaloids, lipid nanoparticles, polymer micelles)
• Stabilization of enzymes, antibodies, and plasmid DNA prior to long-term storage
• Preparation of calibration standards for GC-MS and LC-MS analysis
• Drying of forensic evidence samples where solvent retention must be minimized
• R&D-scale formulation development for parenteral and inhalation drug products
• Removal of residual solvents from synthetic intermediates without thermal degradation

FAQ

What types of organic solvents can the FD-1E-110+ safely handle?
It is validated for solvents with boiling points below 100 °C and vapor pressures compatible with −110 °C condensation, including methanol, ethanol, acetone, acetonitrile, dichloromethane, and ethyl acetate—up to 95% concentration by volume.
Is the system suitable for GMP manufacturing environments?
No—it is designed for laboratory-scale R&D and pilot studies. For regulated production, supplementary validation documentation, IQ/OQ protocols, and enhanced software compliance packages must be commissioned separately.
Can I monitor sample temperature during primary drying?
Yes. Two calibrated Pt100 sensors are included; one monitors chamber ambient temperature, the other interfaces directly with user-supplied thermocouple probes inserted into representative vials.
Does the manifold configuration support automatic stoppering?
No—the FD-1E-110+ is a non-stoppering manifold model. Stoppering capability requires the FD-1D-110+ (manifold + hydraulic stopper) variant.
What vacuum pump is recommended for optimal performance?
A 2 L/s dual-stage oil-sealed rotary vane pump (e.g., KNF NRP series or equivalent) is supplied; optional upgrades include oil-free scroll pumps and hydrocarbon-free diaphragm units for solvent-sensitive applications.
