Chromatography Refrigerators

Chromatography Refrigerators for Pharmaceutical, Clinical, and Research Laboratories

Chromatography refrigerators are purpose-built laboratory refrigeration units designed to support chromatographic workflows by maintaining precise 1°C to 10°C temperature control while accommodating heat-generating equipment such as protein purifiers, HPLC pumps, and fraction collectors inside the cabinet. The ARES Cool line offered through ARES Scientific cold storage includes seven configurations across two series, all engineered for pharmaceutical research, clinical chemistry, blood banking, and FDA/GMP-regulated sample storage. Each unit pairs a microprocessor temperature controller with forced-draft air circulation and R290 hydrocarbon refrigerant, providing energy-efficient operation suitable for continuous-duty laboratory deployments. The ARES Cool series fits within the broader laboratory refrigerators assortment, complementing upright general-purpose models and undercounter units for facilities requiring chromatographic-grade temperature management.

Each unit features a microprocessor temperature controller with integrated digital display and alarm functions, eight to twelve adjustable shelves on ½" increments, and self-closing glass doors with keyed locks. Capacity options span 36 cu. ft. (dual-door), 49 cu. ft. (dual-door, Energy Star certified), and 72 cu. ft. (triple-door). Basic series units carry a one-year parts and labor warranty plus a five-year compressor warranty, supporting research benches, clinical chemistry workspaces, and general laboratory refrigeration deployments.

Plus Series Configurations
The Plus series chromatography refrigerator (ARS-HC-CP-26, ARS-HC-CP-36, ARS-HC-CP-49, ARS-HC-CP-72) adds a temperature display and alarm module that operates 100% independently of the microprocessor controller, providing redundant monitoring for GMP, GLP, and CLIA-regulated environments. Plus series units include two side wall port holes versus one on Basic series, supporting more complex chromatographic equipment integration. Capacity options span 26 cu. ft. (single-door, Energy Star), 36 cu. ft. (dual-door), 49 cu. ft. (dual-door, Energy Star), and 72 cu. ft. (triple-door with locking casters). Plus series units carry a two-year parts and labor warranty and the same five-year compressor warranty.

Features and Technology in ARES Cool Chromatography Refrigeration

Temperature Control and Air Circulation
Each ARES Cool chromatography refrigerator uses a microprocessor temperature controller with 0.1°C resolution to maintain a stable 1°C to 10°C internal environment. An interior fan-driven, forced-draft air circulation system distributes cooled air uniformly across all shelf levels, delivering rapid recovery after door openings — a critical performance parameter when laboratory staff access the cabinet frequently for chromatographic sample loading or fraction collection. The combination meets temperature uniformity requirements for pharmaceutical reagent storage, biological sample preservation, and chromatographic method development.

Refrigeration System and Insulation
All seven units use a hermetic compressor paired with R290 hydrocarbon natural refrigerant — an EPA-compliant choice with significantly lower global warming potential than hydrofluorocarbon refrigerants. Cabinets are foamed-in-place with high-density urethane insulation and finished in white powder-coated steel inside and out. Cycle defrost handles ice management automatically without chart-recorder intervention. Three units (CB-49, CP-26, CP-49) carry Energy Star certification for efficiency-focused multi-unit installations.

Monitoring, Alarms, and Compliance Integration
Every ARES Cool chromatography refrigerator includes audible and visual high/low temperature alarms, sensor error detection, power failure alerts, alarm validation, and alarm mute with ring back. RS-485 MODBUS digital communication and remote alarm contacts integrate units into facility-wide monitoring systems for GLP and GMP documentation requirements. All seven SKUs are ETL and C-ETL listed and certified to UL471. Plus series units add an independent alarm module that operates separately from the microprocessor — a redundancy buyers in FDA-regulated and clinical environments routinely specify.

Applications and Regulatory Context

Pharmaceutical and Clinical Workflows
Chromatography refrigerators serve pharmaceutical research and development, clinical chemistry, hospital pharmacy compounding, and pharmaceutical manufacturing quality control. Typical contents include chromatographic samples, buffer solutions, protein purification media, reagents, biological standards, and temperature-sensitive pharmaceuticals. Facilities operating under FDA 21 CFR Part 211 (pharmaceutical cGMP) and USP <797> (sterile compounding) frequently specify redundant temperature monitoring of the type provided by ARES Cool Plus series units. The product line supports pharmaceutical manufacturing environments as well as pharmacy and nursing compounding operations.

Blood Bank, Research, and Testing Environments
Beyond pharmaceutical use, chromatography refrigerators serve blood bank operations for plasma and reagent storage, university research laboratory equipment deployments, and contract testing facilities. The two-outlet electrical requirement — one for the unit and one for the interior duplex outlet — enables researchers to operate protein purifiers, fraction collectors, and HPLC equipment inside the cabinet without external cord routing. The 3/4" probe access port supports validation studies and continuous temperature mapping required for ISBER best practices and CLIA-certified clinical laboratories.

Frequently Asked Questions About Chromatography Refrigerators

What is a chromatography refrigerator?
A chromatography refrigerator is a laboratory refrigeration unit designed to maintain a precise 1°C to 10°C internal temperature while accommodating heat-generating chromatographic equipment inside the cabinet. Chromatography refrigerators include features absent from general-purpose laboratory refrigerators, including interior duplex outlets for equipment power, side wall port holes for tubing and probe pass-through, and forced-draft air circulation sized to compensate for internal heat loads from protein purifiers, HPLC pumps, and fraction collectors.

What is the difference between a chromatography refrigerator and a general-purpose laboratory refrigerator?
A chromatography refrigerator is engineered to operate equipment inside the cabinet — it includes an interior duplex electrical outlet, one or two side wall port holes for tubing pass-through, and a forced-draft refrigeration system sized to handle internal heat loads. General-purpose laboratory refrigerators store materials only and lack the internal power and pass-through accommodations chromatographic workflows require. Both refrigerator types share microprocessor temperature control and 1°C to 10°C ranges.

What is the difference between Basic series and Plus series ARES Cool chromatography refrigerators?
The Plus series adds a temperature display and alarm module that operates 100% independently of the microprocessor controller, providing redundant monitoring for GMP, GLP, and CLIA-regulated environments. Plus series units also include two side wall port holes (versus one on Basic) and a two-year parts and labor warranty (versus one year on Basic). The five-year compressor warranty and 1°C to 10°C temperature range are identical across both series.

What temperature range do ARES Cool chromatography refrigerators maintain?
ARES Cool chromatography refrigerators maintain an adjustable temperature range of 1°C to 10°C with 0.1°C controller resolution. The microprocessor temperature controller and forced-draft air circulation system together provide temperature uniformity across shelf levels and rapid recovery after door openings. The range covers standard requirements for chromatographic sample storage, reagent preservation, buffer storage, and pharmaceutical materials requiring controlled refrigerated conditions.

Do ARES Cool chromatography refrigerators meet GMP and CLIA monitoring requirements?
ARES Cool chromatography refrigerators provide the monitoring infrastructure required for GMP and CLIA compliance: audible and visual high/low temperature alarms, sensor error detection, power failure alerts, RS-485 MODBUS digital communication, and remote alarm contacts for facility monitoring integration. Plus series units add an independent alarm module operating separately from the primary controller — a redundancy facilities operating under FDA 21 CFR Part 211 and CLIA frequently specify in procurement documents.

What electrical service do chromatography refrigerators require?
ARES Cool chromatography refrigerators operate on 115V, 60 Hz facility power with amperage ranging from 3 Amps (CP-26, 1/5 HP) to 7.5 Amps (CB-72 and CP-72, 1/2 HP). All seven units require two separate facility electrical outlets — one for the refrigerator itself and one for the interior duplex outlet that powers chromatographic equipment inside the cabinet. Each unit ships with a NEMA 5-15 plug.

What refrigerant do ARES Cool chromatography refrigerators use?
ARES Cool chromatography refrigerators use R290 hydrocarbon natural refrigerant, an EPA-compliant choice with significantly lower global warming potential than hydrofluorocarbon refrigerants.
