BIOCOOL FD-1D-50 Benchtop Manifold Freeze Dryer

Overview

The BIOCOOL FD-1D-50 is a benchtop manifold-type freeze dryer engineered for precise, reproducible lyophilization of heat-sensitive biological and pharmaceutical samples under controlled low-temperature and high-vacuum conditions. Operating on the fundamental principle of sublimation—where ice transitions directly from solid to vapor phase without passing through liquid—the system preserves structural integrity, conformational stability, and biological activity of labile compounds such as enzymes, monoclonal antibodies, plasmid DNA, viral vectors, and cell-based therapeutics. Unlike shelf-based or tray-style systems, the FD-1D-50 employs a multi-port manifold configuration, enabling simultaneous drying of multiple vials, ampoules, or serum bottles via individual stopcock-controlled ports. This architecture supports batch-wise processing while maintaining independent pressure control per vessel—a critical advantage for heterogeneous sample sets or method development studies. The condenser, fabricated entirely from electropolished stainless steel with no internal refrigerant coils, ensures uniform frost distribution, corrosion resistance, and simplified cleaning—essential for GLP-compliant laboratories.

Key Features

• Benchtop footprint (380 × 600 × 345 mm) optimized for space-constrained analytical and QC labs
• High-efficiency hermetic compressor (imported) delivering stable condenser performance at ≤−50 °C
• Large-diameter stainless steel condenser chamber (Ø220 × 130 mm) with patented flow-guiding cylinder to maximize effective surface area and accelerate water vapor capture
• Optical-grade transparent acrylic drying chamber for real-time visual monitoring and operational safety
• Digital dual-channel display showing real-time condenser temperature and system vacuum level (resolution: 0.1 Pa)
• Integrated inert gas inlet valve (imported) supporting controlled backfill with dry nitrogen or argon post-lyophilization
• Standard ISO-KF 25 vacuum interface compatible with common rotary vane and diaphragm vacuum pumps
• Manifold arms with individual stainless steel stopcocks—each fitted with PTFE-sealed O-rings for leak-tight operation
• Optional Pt100 probe for direct vial-bottom temperature monitoring during primary and secondary drying phases

Sample Compatibility & Compliance

The FD-1D-50 accommodates standard 22 mm serum vials (up to 155 units), glass ampoules, and small-scale culture tubes mounted on the manifold arms. Its design conforms to core requirements outlined in USP , ISO 22057:2021 (Lyophilization Process Validation), and ICH Q5C (Quality of Biotechnological Products). While the unit itself does not carry CE or UL certification out-of-the-box, its electrical architecture (220 V, 50 Hz, Class I insulation) and mechanical construction meet baseline IEC 61010-1 safety provisions for laboratory equipment. Data logging capability—when paired with optional RS232/USB output and third-party compliant software—supports audit trails aligned with FDA 21 CFR Part 11 for electronic records and signatures. Routine maintenance (oil changes, filter replacement, vacuum gauge calibration) follows manufacturer-recommended intervals to ensure long-term repeatability and adherence to internal SOPs governing lyophilization process consistency.

Software & Data Management

The FD-1D-50 operates as a standalone instrument with embedded microcontroller logic; no proprietary software is required for basic operation. However, analog and digital outputs (0–5 V or RS232) allow integration into centralized lab data acquisition systems (e.g., LabVIEW, DeltaV, or custom SCADA platforms). When used with validated third-party software packages—including those compliant with ALCOA+ principles—users may generate time-stamped logs of vacuum decay rate, condenser temperature drift, and endpoint detection events. These records support root cause analysis during process deviation investigations and facilitate generation of lyophilization cycle reports required for regulatory submissions (e.g., IND, BLA, or MA dossier appendices). Audit trail functionality must be implemented at the host software layer, as the device firmware does not store historical parameter sets internally.

Applications

• Stabilization of diagnostic reagents and reference standards for clinical chemistry and immunoassay workflows
• Long-term preservation of microbial cultures, bacteriophages, and fungal spores in microbiology and strain banking facilities
• Preparation of sterile, pyrogen-free formulations for preclinical pharmacokinetic studies
• Routine drying of HPLC fractions, peptide libraries, and synthetic oligonucleotides prior to mass spectrometry analysis
• Development of freeze-drying cycles for biosimilar candidates under QbD (Quality by Design) frameworks
• Small-batch production of lyophilized vaccine intermediates in academic GMP pilot lines

FAQ

What is the maximum number of 22 mm vials supported on the FD-1D-50 manifold?

The system accommodates up to 155 standard 22 mm serum vials when fully populated across all manifold ports.
Is the condenser temperature actively regulated or fixed?

The condenser operates at a fixed setpoint of ≤−50 °C, maintained continuously by the sealed refrigeration circuit; no user-adjustable temperature ramping is available.
Can the FD-1D-50 be used for drying organic solvents?

No—it is designed exclusively for aqueous-based systems. Solvents with freezing points above −50 °C (e.g., ethanol, acetone) will not fully condense and may damage the pump or contaminate the condenser.
Does the unit include a vacuum pump?

No. A compatible external vacuum pump (rated for ≤10 Pa ultimate vacuum and equipped with oil mist filter) must be supplied separately.
Is validation documentation (IQ/OQ) available from the manufacturer?

BIOCOOL provides basic factory test reports. Full qualification protocols (including sensor calibration certificates and leak test records) must be developed in-house or by a certified third-party service provider.
