BioCoool YC-1PLUS Chromatography Refrigerator

Overview

The BioCoool YC-1PLUS Chromatography Refrigerator is an engineered environmental control system designed specifically for biomolecular separation workflows requiring stable, low-temperature operation. It operates on a precision-controlled refrigeration cycle optimized for chromatographic applications—particularly those involving AKTA systems, FPLC/HPLC column packing and elution, affinity purification, size-exclusion chromatography (SEC), and ion-exchange protocols where thermal stability directly impacts resolution, binding kinetics, and sample integrity. Unlike general-purpose laboratory refrigerators, the YC-1PLUS integrates structural, thermal, and ergonomic features aligned with ISO 15190:2020 (laboratory safety) and ICH Q5C (stability testing of biotechnological/biological products) principles. Its 1–10°C operating range—with ±3°C uniformity across the full 800 L chamber—ensures reproducible retention times and minimizes conformational drift in temperature-sensitive proteins, enzymes, antibodies, and nucleic acid complexes during extended runs.

Key Features

• Stainless steel interior chamber (AISI 304 grade) with seamless welds and rounded corners for easy cleaning and compliance with GLP/GMP cleanroom-compatible maintenance protocols.
• Double-glazed, low-emissivity tempered glass door with integrated mechanical lock—provides visual monitoring without compromising thermal integrity or risking accidental door opening during critical runs.
• Rear-mounted condenser fan assembly eliminates internal moisture accumulation; no condensate drip forms on shelves or columns—critical for preventing cross-contamination and preserving column bed integrity.
• Dual-layer thermal insulation (polyurethane foam, ≥80 mm thickness) ensures minimal heat ingress and energy-efficient long-term operation at target setpoints.
• Two vertically adjustable stainless steel column mounting rods (M10 threaded, height-adjustable from 300–1700 mm) accommodate standard 1.5 m preparative columns and modular fraction collectors.
• Two heavy-duty open-grid shelves (650 × 345 mm, load-rated to 50 kg each) with optional motorized sliding rails (635 × 635 mm, 125 kg capacity) for seamless AKTA tubing routing and system integration.
• Integrated LED task lighting + UV-C disinfection lamp (254 nm, 15 W) enables safe post-run decontamination without chemical residues—validated per ISO 15858 for surface microbial reduction.
• 7-inch industrial-grade capacitive touchscreen HMI with real-time temperature curve visualization, event logging, and parameter configuration (setpoint, alarm thresholds, fan speed).

Sample Compatibility & Compliance

The YC-1PLUS supports a broad spectrum of chromatographic hardware and consumables—including GE Cytiva AKTA pure/avant systems, Bio-Rad NGC platforms, and custom-built FPLC rigs—as well as prepacked and self-packed columns (HiTrap, HiPrep, Tricorn, XK series). Its internal height of 1700 mm accommodates vertical column orientation up to 1.5 m without tilting, reducing hydrodynamic dispersion and backpressure fluctuations. The cabinet meets electrical safety requirements per IEC 61010-1 and electromagnetic compatibility per EN 61326-1. Optional RS-485 interface enables integration into centralized lab infrastructure for audit-ready temperature traceability under FDA 21 CFR Part 11-compliant data management systems when paired with validated third-party software.

Software & Data Management

Data acquisition and reporting are handled via embedded firmware supporting continuous temperature logging at user-defined intervals (1–60 min). All records—including setpoint changes, alarm events, door openings, and UV lamp cycles—are timestamped and stored internally (≥30 days) and exportable via USB 2.0 to CSV format for offline analysis in Excel or statistical packages (e.g., JMP, Minitab). Remote supervision is available through a secure web-based dashboard (PC) or native iOS/Android application—both providing real-time status alerts, historical trend graphs, and configurable SMS/email notifications for out-of-spec conditions. Audit trails include operator ID (via login), action type, and parameter values—supporting ALCOA+ data integrity principles.

Applications

• Preparative protein purification under cold-chain conditions (e.g., monoclonal antibody capture, His-tag elution at 4°C).
• Storage and operation of temperature-sensitive resins (e.g., Protein A, Ni-NTA, Q Sepharose) to extend ligand stability and binding capacity.
• Long-duration gradient elutions (>24 h) requiring consistent thermal environment to prevent baseline drift or peak broadening.
• Cold-room alternative for small-to-midsize labs lacking architectural HVAC integration—reducing infrastructure cost while maintaining ISO 14644-1 Class 8 air cleanliness via closed-loop air filtration.
• Stabilization of labile metabolites, co-factors (e.g., NADH, ATP), and enzyme inhibitors during assay development.

FAQ

What is the recommended calibration frequency for the YC-1PLUS temperature sensor?
Annual verification using NIST-traceable thermistors is advised; internal sensor drift is typically <±0.5°C/year under continuous operation.
Can the YC-1PLUS be installed in non-air-conditioned rooms?
Yes—its condenser is rated for ambient temperatures up to 35°C and relative humidity ≤80% RH (non-condensing); however, sustained operation above 30°C may reduce compressor lifespan.
Is the UV disinfection cycle programmable?
Yes—duration (5–60 min), intensity level, and activation schedule can be configured via touchscreen or remote interface.
Does the sliding shelf option require additional power supply?
No—the rail mechanism is manually operated; motorized version (optional) uses 24 V DC input and draws <1.2 A peak current.
Are replacement parts such as door gaskets or UV lamps available separately?
Yes—BioCoool provides OEM-certified spare parts with documented shelf life (UV lamps: 8,000 hr typical service life; silicone door seals: 5-year warranty).
