BINDER UF V Series Ultra Low Temperature Freezer

Overview

The BINDER UF V Series Ultra Low Temperature Freezer is an engineered solution for long-term, high-integrity cryogenic storage of biological specimens—including primary cells, stem cell lines, genomic DNA, RNA, tissue biopsies, and temperature-sensitive reagents—in academic research laboratories, biobanks, clinical diagnostics centers, and pharmaceutical development facilities. Operating within a stable temperature range of –40 °C to –86 °C, the UF V leverages a dual-stage cascade compressor system to achieve deep-cold performance while maintaining thermal uniformity (< ±2.5 °C at –80 °C, per IEC 61000-4-2 validation protocol) and minimal temperature fluctuation during door openings. Its refrigeration architecture uses environmentally compliant, non-ozone-depleting refrigerants R-404A (low-stage) and R-508B (high-stage), fully aligned with EU F-Gas Regulation (EU No 517/2014) and EPA SNAP program requirements. The unit’s structural integrity is reinforced by a stainless steel (AISI 304) inner chamber and robust external housing, ensuring resistance to corrosion, condensation ingress, and mechanical stress over extended operational lifecycles exceeding 15 years under GLP-compliant usage conditions.

Key Features

• Multi-layer insulation combining vacuum insulation panels (VIPs) and high-density polyurethane foam—reducing heat transfer by >40% compared to conventional PU-only designs
• Electromechanical door lock with programmable access control; optional RFID reader integration supports role-based user authentication and audit-trail generation per 21 CFR Part 11 Annex 11 guidelines
• Redundant alarm architecture: battery-backed audible/visual alerts, dry-contact relay outputs (zero-voltage), 4–20 mA analog signal for building management systems (BMS), and real-time hour meter logging
• RS 422 serial interface for direct connection to laboratory information management systems (LIMS); optional Ethernet module enables remote monitoring via SNMP or Modbus TCP
• Configurable hinge orientation (left/right) and field-installable accessories—including water-cooling kits for ambient environments >30 °C and CO₂ backup cooling modules for power-failure resilience
• Three stainless steel pull-out shelves with load-rated capacity of 25 kg per shelf; interior optimized for standard cryobox formats (e.g., 100-cell polypropylene boxes, 50/75 mm depth)

Sample Compatibility & Compliance

The UF V series accommodates standard cryogenic sample carriers including ISO/IEC 17025-accredited cryovials (1.0–5.0 mL), Nunc™-format freezing racks, and ANSI/SLAS-compliant 96-well plates stored in insulated carriers. Internal cavity geometry supports vertical stacking of up to four 100-cell polypropylene boxes per shelf without obstructing airflow pathways. All models comply with IEC 61010-1 (Safety Requirements for Electrical Equipment), IEC 60068-2-1/2 (Cold/ Dry Testing), and EN 60335-2-89 (Particular Requirements for Refrigerating Appliances). Optional configurations meet FDA 21 CFR Part 11 requirements when paired with BINDER’s validated PDF data logger and electronic signature workflow. Units are CE-marked and certified to DIN EN ISO 9001:2015 quality management standards at the German manufacturing facility.

Software & Data Management

While the UF V operates as a standalone instrument, its digital interface ecosystem supports traceable, compliant data handling across regulated environments. The optional USB PDF data logger records temperature, door status, alarm events, and compressor runtime at user-defined intervals (1–60 min), generating time-stamped, digitally signed PDF reports compatible with eDMS archives. When equipped with the Ethernet module, the freezer integrates into centralized monitoring platforms using open protocols (Modbus TCP, SNMP v3). Audit trails—including user logins, parameter changes, and alarm acknowledgments—are retained for ≥12 months onboard and exportable via secure FTP. All firmware updates undergo version-controlled release cycles with full change documentation available upon request for GxP validation support.

Applications

• Long-term archiving of human biospecimens in biorepositories accredited to ISBER Best Practices and CAP Biorepository Standards
• Cryopreservation of induced pluripotent stem cells (iPSCs) and primary neuronal cultures requiring uninterrupted –80 °C stability
• Storage of mRNA vaccine intermediates and cold-chain-sensitive monoclonal antibody drug substances
• Backup cold storage for liquid nitrogen dewars during maintenance or supply interruption
• Environmental simulation labs requiring stable ultra-low baseline temperatures for material property testing (e.g., polymer embrittlement studies per ASTM D746)

FAQ

What is the typical recovery time after a 30-second door opening at –80 °C?
Recovery to ±1 °C of setpoint typically occurs within 8–12 minutes under standard lab conditions (22 °C ambient, 50% RH), verified per ISO 23993:2021 Annex C test methodology.
Can the UF V be validated for IQ/OQ/PQ in GMP environments?
Yes—BINDER provides factory-issued validation templates, sensor calibration certificates (traceable to DKD/DAkkS), and on-site qualification support through authorized service partners.
Is water cooling mandatory for operation above 25 °C ambient?
Not mandatory, but strongly recommended above 28 °C ambient to maintain compressor longevity and energy efficiency; water-cooled variants reduce electrical load by ~22% versus air-cooled equivalents.
Does the unit support remote alarm notification via SMS or email?
Yes—when integrated with the optional GSM remote alert box, configurable thresholds trigger SMS/email alerts to up to five designated recipients with timestamped event logs.
Are replacement parts and service manuals available globally?
All spare parts—including VIP panels, compressor assemblies, and control boards—are stocked in regional distribution hubs (USA, Germany, Singapore), with technical documentation accessible via BINDER’s secure customer portal under NDA.
