BioCoool YC-2APLUS Chromatography Refrigerator

Overview

The BioCoool YC-2APLUS Chromatography Refrigerator is an engineered environmental control system designed specifically for low-temperature chromatographic workflows in life science laboratories. It operates on a precision air-cooled refrigeration principle, utilizing a hermetically sealed compressor and rear-mounted condenser fan to maintain stable thermal conditions between 1 °C and 10 °C — a range optimized for preserving column integrity, minimizing buffer crystallization, and ensuring reproducible elution profiles during protein purification, affinity chromatography, and size-exclusion applications. Unlike general-purpose laboratory refrigerators, the YC-2APLUS integrates structural and functional adaptations for chromatography systems: its 1960 mm total height complies with standard elevator and doorway clearances, while its internal height of 1500 mm accommodates vertical column assemblies up to 1.5 m without disassembly. The cabinet’s architecture supports modular integration with AKTA, ÄKTA avant, or other FPLC/HPLC platforms via dedicated sliding rails and reinforced load-bearing shelves.

Key Features

• Stainless steel interior chamber with seamless welds and rounded corners for easy decontamination and compliance with GLP cleaning protocols.
• Dual-layer tempered glass door with mechanical lock, providing visual monitoring without thermal disturbance or condensation buildup.
• Two adjustable stainless steel column support rods and two open-frame heavy-duty shelves (605 × 525 mm), rated for static loads up to 125 kg when equipped with optional sliding trays.
• Integrated LED task lighting and UV-C disinfection lamp (254 nm), enabling routine cabinet sanitation without external equipment.
• 7-inch industrial-grade capacitive touchscreen interface with real-time temperature curve visualization, historical data overlay, and parameter adjustment capability.
• Dual-stage alarm system: independent over-temperature and differential-temperature alerts (e.g., sensor drift detection), configurable via HMI or remote interface.
• Low-humidity cooling design eliminates condensate drip, preventing moisture-related degradation of electrical connections, tubing, and column hardware.
• Built-in AC power outlets (IEC 60320 C13), positioned to avoid interference with fluidic routing and compatible with standard lab-grade pumps and detectors.

Sample Compatibility & Compliance

The YC-2APLUS supports a broad spectrum of chromatographic configurations, including gravity-fed, peristaltic-pump-driven, and high-pressure FPLC systems. Its interior geometry accommodates columns up to 100 cm in length and 5 cm in diameter, as well as multi-tiered fraction collectors, buffer reservoirs, and inline degassers. All materials in contact with the internal environment meet ISO 8573-1 Class 3 purity requirements for non-corrosive, non-particulate surfaces. While not certified to UL/EN 61010-1 for hazardous location use, the unit conforms to IEC 60068-2 environmental stress testing standards for operational stability under continuous 24/7 duty cycles. Optional RS-485 communication enables integration into centralized facility monitoring systems compliant with ASTM E2047 and ISO/IEC 17025 documentation frameworks.

Software & Data Management

Data acquisition and configuration are managed through embedded firmware supporting time-stamped logging at user-selectable intervals (1–60 min). Temperature readings from dual NTC sensors (working + redundant) are stored locally on internal flash memory and exportable via USB 2.0 to CSV-compatible formats for audit trail reconstruction. Remote access is enabled through TCP/IP-enabled Ethernet or Wi-Fi modules (optional), allowing authenticated web-based parameter modification, real-time status viewing, and alarm acknowledgment from any authorized workstation or mobile device. The system logs all configuration changes with timestamp and operator ID, satisfying FDA 21 CFR Part 11 requirements for electronic records when deployed with institutional identity management infrastructure.

Applications

• AKTA-based protein purification workflows requiring consistent 4 °C column equilibration and fraction collection.
• Ion-exchange and hydrophobic interaction chromatography where temperature-induced resin swelling must be minimized.
• Long-duration gradient runs (>24 h) necessitating uninterrupted thermal stability and uninterruptible power support (via external UPS).
• Cold-chain storage of pre-packed columns, ligand-coupled resins, and temperature-sensitive eluents prior to use.
• Multi-user core facilities deploying shared FPLC infrastructure across departments, where access control and usage logging are essential.
• Academic and contract research labs conducting method development under ISO 13485 or GMP-aligned quality systems.

FAQ

What is the maximum column height supported inside the YC-2APLUS?

The internal usable height is 1500 mm, permitting installation of vertical columns up to 150 cm in length without removal of top fittings.
Is the unit suitable for use with organic solvents commonly used in HPLC?

The cabinet is not rated for flammable vapor environments; it is intended for aqueous and low-volatility buffer systems only. Solvent-resistant modifications require factory consultation.
Can the sliding shelf be retrofitted to an existing YC-2PLUS unit?

Yes — the sliding rail assembly and reinforced tray are available as field-installable kits, subject to mechanical compatibility verification.
Does the system support 21 CFR Part 11-compliant electronic signatures?

The base firmware provides audit-trail-capable logging; full Part 11 compliance requires integration with third-party identity management and digital signature services.
What maintenance intervals are recommended for the refrigeration system?

Compressor oil and refrigerant levels should be verified annually by certified service personnel; condenser coil cleaning is advised every six months in dust-prone environments.
