EYELA FDM-2010 Benchtop Freeze Dryer (Successor to FDU-2200)

Overview

The EYELA FDM-2010 is a benchtop freeze dryer engineered for reproducible, low-moisture lyophilization of small- to medium-batch laboratory samples. As the designated successor to the widely deployed FDU-2200, it integrates refined thermal management, enhanced process autonomy, and robust compliance-ready architecture. Its core operation follows the standard three-stage lyophilization principle—freezing, primary drying (sublimation under vacuum), and secondary drying (desorption)—with precise coordination between the dual-compressor cold trap (−80 °C) and integrated digital vacuum monitoring. Designed for use in regulated research environments—including pharmaceutical development, biologics stabilization, and analytical sample preparation—the FDM-2010 supports method development aligned with ICH Q5C, USP , and ISO 22057 (freeze-drying terminology and performance criteria). The system operates without onboard condenser heating or shelf temperature control, positioning it as a dedicated condensation-focused unit optimized for vial-based or flask-based drying when paired with optional manifold or chamber configurations.

Key Features

• Dual 500 W eco-friendly refrigeration system using R290/R170 hydrocarbon blend—provides stable −80 °C cold trap performance with reduced global warming potential (GWP) versus legacy R404A systems
• High-efficiency condensation capacity of 1 L/24 h, suitable for routine drying of ≤500 mL total aqueous volume per cycle across multi-flask or multi-vial configurations
• Real-time digital Pirani vacuum monitoring (0.0–533 Pa range) with on-screen trend display—enables correlation of pressure decay rate with ice load and sublimation progress
• Hot-gas defrost mechanism with cylinder-cooled cold trap geometry—facilitates complete ice removal and simplifies SUS304 surface cleaning between cycles
• Automated operational logic: detects flask installation status via vacuum rise rate and cold trap temperature stabilization; initiates pump sequencing accordingly
• Integrated timer logs cumulative vacuum pump runtime—supports preventive maintenance scheduling per ISO 21508 and manufacturer-recommended oil change intervals
• Fail-safe vacuum break function with 0.2 µm hydrophobic particulate filter on inlet line—prevents ambient contamination during repressurization
• Self-diagnostic control panel with fault-code display and configurable alarm thresholds for vacuum, temperature, and electrical anomalies

Sample Compatibility & Compliance

The FDM-2010 accommodates standard 10–50 mL glass vials, round-bottom flasks (up to 1000 mL), and serum bottles via optional stainless-steel manifolds or a dedicated freeze-drying chamber. All wetted surfaces contacting condensate or vapour paths are constructed from electropolished SUS304 stainless steel, ensuring corrosion resistance and cleanability per ASTM A967 standards. While the unit itself does not carry CE marking for medical device use, its electrical safety design complies with IEC 61010-1:2010 (measurement, control, and laboratory equipment). When operated within validated protocols—including documented IQ/OQ procedures and calibrated vacuum/temperature sensors—it meets foundational requirements for GLP-compliant sample archiving and GMP-aligned pre-formulation studies. Data integrity is supported through non-volatile runtime logging and manual export capability via USB (optional accessory).

Software & Data Management

The FDM-2010 operates via an embedded microcontroller with no proprietary software dependency. All operational parameters—including vacuum setpoints (if enabled via external controller), cycle timers, and alarm thresholds—are configured directly on the 3.4-inch monochrome LCD interface with tactile membrane keys. Real-time values for cold trap temperature, chamber pressure, and pump runtime are continuously displayed. For laboratories requiring electronic record retention, the system supports integration with third-party data loggers via analog output (0–5 V) for vacuum and temperature signals. Audit trail functionality is maintained manually via operator logbooks; however, when paired with compliant LIMS or ELN platforms, the logged runtime data satisfies basic FDA 21 CFR Part 11 traceability requirements for equipment usage history.

Applications

• Stabilization of heat-labile biologics (e.g., monoclonal antibodies, enzymes, plasmid DNA) prior to long-term storage or transport
• Preparation of reference standards for chromatographic analysis (HPLC, GC-MS) where residual solvent or water content must be minimized
• Drying of microbial cultures, tissue extracts, and botanical concentrates for metabolite profiling and stability testing
• Lyophilization of diagnostic reagents, including ELISA kits and lateral flow assay components
• Method development for scalable freeze-drying processes—serving as a platform for parameter screening (e.g., shelf temperature ramping, vacuum modulation) prior to pilot-scale trials

FAQ

Does the FDM-2010 include a vacuum pump?
No. A separate vacuum pump rated at ≥50 L/min is required and must be connected via the dedicated 125 V/6 A outlet. Oil-free scroll pumps are recommended for applications requiring low hydrocarbon backstreaming.
Can the cold trap temperature be adjusted?
No. The dual-compressor system maintains a fixed −80 °C operating point optimized for high-efficiency water vapour capture across common solvents (e.g., water, tert-butanol, acetonitrile mixtures).
Is the unit compatible with inert gas purging?
Yes. The vacuum break inlet accepts nitrogen or argon supply lines via standard 1/4″ NPT fittings; the 0.2 µm filter remains effective under inert gas flow.
What maintenance intervals are recommended?
Vacuum pump oil replacement every 500 hours of operation; cold trap cleaning after each 5–10 cycles depending on sample load; annual verification of Pirani gauge calibration and refrigerant charge integrity.
How is power failure handled?
The system retains all settings and resumes operation from the last known state upon power restoration—provided the interruption duration is ≤15 minutes and the cold trap remains below −60 °C.
