Purpose-Built Cold Storage for Instrumentation, Not Just Samples
A chromatography refrigerator solves a problem that a standard laboratory refrigerator was never designed for: housing an active HPLC system, its columns, and its tubing inside a temperature-controlled enclosure while the instrument runs. That requires pass-through provisions for tubing and cabling, mast options to support column hardware, and enough interior clearance to arrange a working system rather than shelved sample boxes. MediDepot carries 58 chromatography refrigerator configurations from VWR, True Scientific, and American BioTech Supply spanning 16 to 72 cu. ft.
The distinction is worth emphasizing because it drives the entire specification. Labs occasionally try to adapt a standard reach-in refrigerator for chromatography work and run into the same obstacles: nowhere to route tubing without compromising the door seal, no mounting point for column hardware, and interior shelving that cannot be reconfigured around an instrument. Chromatography-specific units address these from the design stage.
Laboratories That Depend on These Units

Product Lines Available in This Collection
MediDepot’s chromatography refrigerator selection is organized across three manufacturers and several distinct series.
VWR Plus Series (VWR-HCCP) Glass door chromatography refrigerators with a digital display and alarm module, available in 16, 23, 26, 33, 36, 47, 49, 69, and 72 cu. ft. capacities. This series covers the broadest capacity ladder in the collection, letting a lab match footprint to the number of instruments being housed.
VWR Performance Series (VWR-HCCP-TS) The same capacity ladder (16, 23, 26, 33, 36, 47, 49, 69, and 72 cu. ft.) upgraded with a touchscreen interface and data logging. For laboratories operating under quality systems that require documented temperature history, the logging capability is typically the deciding factor.
VWR Standard Series (VWR-HCCS) Glass door chromatography refrigerators in 16, 23, 26, 33, 36, 47, 49, 69, and 72 cu. ft., available with either swing doors or sliding doors depending on the model. Sliding door versions suit installations where door swing clearance is constrained.
VWR GDM Basic Chromatography Refrigerators Natural refrigerant units in white or white exterior with stainless steel interior finishes, available in 23, 41, 47, 49, and 72 cu. ft. capacities. These are offered in configurations with and without a mast (designated 1P1D1M, 2P1D1M, and 1P1D), and in both swing door and sliding door variants, giving labs direct control over whether column mounting hardware is included.
VWR TS Series Basic Reach-In Stainless steel glass door laboratory refrigerators in 23, 49, and 72 cu. ft. capacities, positioned as basic reach-in units within the chromatography category.
True Scientific The TSCI-600CR-SWG chromatography refrigerator offers 22.13 cu. ft. of capacity with a glass door, a 2°C to 10°C range, an HPLC mast option, and R290 natural refrigerant.
American BioTech Supply Additional chromatography-suitable refrigerator configurations complement the VWR and True Scientific offerings within this collection.

Building Your Specification
Selecting a chromatography refrigerator involves a few decisions that standard lab refrigerator purchases do not require.
- Mast requirement. Determine whether you need integrated column mounting hardware. GDM models are offered both with a mast (1P1D1M, 2P1D1M) and without (1P1D), and the True Scientific TSCI-600CR-SWG offers an HPLC mast option.
- Interior capacity versus instrument count. Size the unit to the number and footprint of the chromatography systems it will house, not to sample volume. A 16 cu. ft. unit suits a single system, while 49 to 72 cu. ft. units accommodate multiple instruments.
- Documentation requirements. If your laboratory operates under a quality system requiring temperature records, choose a Performance Series unit with touchscreen and data logging rather than a display-only model.
- Swing versus sliding doors. Sliding doors, available on several Standard Series and GDM models, reduce the clearance needed in front of the unit, which matters in dense instrument rooms.
- Temperature range. This collection includes ranges of 2°C to 8°C, 1°C to 10°C, 3°C to 5°C, and 2°C to 10°C on the True Scientific model. Confirm the range against your method requirements.
- Interior finish. Stainless steel interiors, available on several VWR models, offer greater durability and chemical resistance than painted interiors in a solvent-adjacent environment.
- Refrigerant considerations. Several GDM models and the True Scientific unit use natural refrigerants, including R290, which may align with institutional sustainability targets.

Buyers should confirm interior dimensions, pass-through port provisions, mast compatibility with their specific chromatography hardware, electrical requirements, and any applicable certifications directly on each product page before ordering. MediDepot does not represent that any unit satisfies a specific laboratory’s regulatory, validation, or quality system requirements; laboratory managers should verify equipment against their own institutional standards and validate performance before placing instruments or samples into service.
Getting the Purchase Right the First Time
A chromatography refrigerator often gets installed around an instrument that is already in service, which makes advance planning particularly valuable.
- Measure the instrument, not just the room. Confirm interior clearance against your chromatography system’s actual dimensions, including any hardware that must sit inside with it.
- Plan tubing and cable routing before delivery. Confirm how lines will pass into the unit and that the arrangement will not compromise the door seal or temperature stability.
- Match control sophistication to your quality system. Adding external monitoring later to a display-only unit is possible but usually less convenient than specifying data logging at purchase.
- Consider door clearance in dense instrument rooms. Sliding door models eliminate the swing arc, which can be the difference between a workable layout and a crowded one.
- Coordinate with facilities early on electrical capacity and heat rejection, particularly for the larger 49, 69, and 72 cu. ft. units.
Frequently Asked Questions
How is a chromatography refrigerator different from a standard laboratory refrigerator?
A chromatography refrigerator is designed to house an operating HPLC or similar system inside the cabinet, with provisions for routing tubing and cabling into the unit and, on many models, a mast for mounting column hardware. A standard laboratory refrigerator is built for shelved sample and reagent storage and generally lacks those provisions.
What is a mast and do I need one?
A mast is mounting hardware inside the refrigerator that supports chromatography columns and associated components. Models in this collection carry designations such as 1P1D1M and 2P1D1M for units with a mast, and 1P1D for units without. Whether you need one depends on how your chromatography hardware is configured and whether it requires vertical mounting support inside the cabinet.
What is the difference between the VWR Plus and Performance series?
Both cover the same 16 to 72 cu. ft. capacity ladder. Plus Series units (VWR-HCCP) use a digital display with an alarm module, showing current conditions and alerting on excursions. Performance Series units (VWR-HCCP-TS) add a touchscreen interface with data logging, capturing temperature history over time for laboratories that require documented records.
Should I choose swing doors or sliding doors?
Sliding doors, available on several Standard Series and GDM models, require no clearance in front of the unit, which helps in dense instrument rooms or narrow aisles. Swing doors provide unobstructed full-width access to the interior, which can be easier when installing or servicing an instrument inside the cabinet.
What capacity do I need for a single HPLC system?
Capacity should be sized to the instrument footprint rather than sample volume. Smaller units in the 16 to 23 cu. ft. range typically suit a single system, while 47 to 72 cu. ft. units accommodate multiple instruments or systems with extensive associated hardware. Confirm interior dimensions against your specific equipment before ordering.
Why do some models use natural refrigerants like R290?
Natural refrigerants such as R290 have lower global warming potential than many conventional alternatives, and laboratories frequently select them to meet institutional sustainability targets. Several GDM models and the True Scientific TSCI-600CR-SWG in this collection use natural refrigerants.
