Overview
The BIOCOOL FD-1B-50 is a compact, benchtop freeze dryer engineered for reliable, small-batch lyophilization under controlled low-temperature and high-vacuum conditions. It operates on the fundamental principle of sublimation—removing water or volatile solvents directly from the frozen solid phase to vapor without passing through the liquid state. This process preserves thermolabile molecular structures, making the system particularly suitable for stabilizing biologics such as enzymes, monoclonal antibodies, vaccines, plasmid DNA, serum proteins, and microbial cultures. Unlike spray drying or air drying, lyophilization minimizes conformational denaturation, oxidation, and hydrolytic degradation—critical for maintaining biological activity, structural integrity, and long-term storage stability. The FD-1B-50 features a dedicated stoppering mechanism that enables in-chamber vacuum sealing of pharmaceutical-grade serum vials (22 mm diameter), supporting GMP-aligned secondary packaging workflows commonly required in preclinical formulation development and reference standard preparation.
Key Features
- Benchtop footprint (380 × 600 × 345 mm) optimized for limited laboratory space without compromising performance.
- Stainless-steel condenser chamber with smooth, coil-free interior surface—enhancing cleanability, corrosion resistance, and ice release efficiency.
- Patented baffle-guided airflow design increases effective condenser surface area and improves vapor capture kinetics during primary drying.
- Imported hermetic scroll compressor delivering stable ≤ −50 °C condenser temperature and consistent sub-13 Pa ultimate vacuum (<10 Pa typical under load).
- Transparent acrylic bell jar with reinforced safety shielding—enabling real-time visual monitoring of sublimation front progression and cake morphology.
- Digital dual-display interface showing real-time condenser temperature and chamber pressure (vacuum level) with ±0.5 °C and ±1 Pa resolution.
- Integrated inert gas backfill valve (standard N₂; optional Ar compatibility) for controlled reconstitution atmosphere and oxygen-sensitive sample handling.
- Pre-freezing capability within the condenser chamber eliminates need for external ultra-low temperature freezers prior to loading.
Sample Compatibility & Compliance
The FD-1B-50 accommodates standard 22 mm serum vials across three stacked Φ180 mm stainless steel shelves—supporting up to 155 vials per batch. Its manifold configuration allows simultaneous processing of heterogeneous samples in varied container formats (vials, flasks, ampoules), while the integrated stoppering function ensures hermetic seal formation under vacuum—meeting USP and ISO 20977:2018 requirements for sterile barrier integrity in lyophilized pharmaceutical intermediates. The unit complies with IEC 61010-1 for electrical safety and meets CE marking directives for laboratory equipment. All wetted surfaces are electropolished 316L stainless steel or FDA-compliant polymers. Data logging (optional) supports 21 CFR Part 11–compliant audit trails when paired with validated software packages.
Software & Data Management
While the base FD-1B-50 operates via intuitive front-panel controls, it is compatible with BIOCOOL’s optional PC-based LyoControl Suite—a Windows application enabling protocol-driven cycle programming, time-stamped parameter logging (Tcond, Pchamber, Tshelf), trend visualization, and CSV export for QC documentation. The system supports configurable alarm thresholds (e.g., vacuum breach >25 Pa, condenser overload >95% capacity), automatic shutdown sequences, and password-protected user access levels. When integrated with enterprise LIMS or ELN platforms via Modbus RTU or RS-485, the FD-1B-50 contributes to fully traceable, ALCOA+–aligned data governance frameworks essential for GLP and GMP environments.
Applications
- Lyophilization of diagnostic reagents, enzyme conjugates, and immunoassay standards.
- Stabilization of bacterial and fungal cultures for long-term strain banking (ATCC/DSMZ compliance).
- Preparation of sterile drug product intermediates in early-phase API development.
- Drying of tissue extracts, plant metabolites, and forensic biological samples requiring structural fidelity.
- Routine dehydration of calibration standards used in mass spectrometry and HPLC reference material preparation.
- Academic research in protein folding studies, cryopreservation optimization, and amorphous solid dispersion characterization.
FAQ
What is the maximum batch capacity for 22 mm vials?
The FD-1B-50 holds approximately 155 standard 22 mm serum vials across three Φ180 mm shelves.
Does the system support shelf temperature control?
No—the FD-1B-50 is a manifold-style unit without heated/cooled shelves; sample freezing occurs in the condenser chamber prior to primary drying.
Can the unit be connected to an external vacuum pump?
Yes—it features standardized KF-16 and ISO-KF25 vacuum ports compatible with oil-free diaphragm pumps and two-stage rotary vane systems.
Is the condenser drain port accessible for manual defrosting?
Yes—a bottom-mounted quick-release valve enables safe, tool-free ice removal after each cycle without disassembly.
What certifications does the FD-1B-50 carry for international use?
CE-marked per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); RoHS-compliant materials; factory-calibrated against NIST-traceable pressure and temperature references.
