About Gram
Gram BioLine is the life science division of a Danish cold storage manufacturer. The BioLine division was founded in 2006 by Gram Commercial, a cooling solutions company whose origins trace back to 1901, and it is headquartered in Vojens, Denmark. Since 1 January 2023 the brand has been held by Gram Scientific ApS as an independent owner, having previously sat under Gram Commercial, filial af Hoshizaki Europe BV. The company makes laboratory refrigerators and laboratory freezers, including ultra-low temperature freezers, ATEX-certified cold storage for flammable material, and biostorage cabinets for biological samples. Its catalogue is organised into named product lines rather than individual models. On Questpair, these cabinets are listed by verified suppliers and distributors across several countries.
Gram BioLine product lines
The brand's range is built around cold storage at defined temperature bands. The BioCompact II line covers smaller refrigerators and freezers, sized for a bench or an under-counter position. BioPlus and BioMidi move up to larger upright cabinets for higher storage volumes. The BioUltra line addresses ultra-low temperature freezing, used for the long-term storage of biological material where samples must be held well below standard freezer temperatures. The HELIX line and the BioLine range more broadly extend these into dedicated laboratory and clinical configurations. Separate from the temperature-band lines sits ExGuard, an explosion-protected range engineered for storing flammable substances in laboratory environments where ordinary refrigeration construction is not permitted.
Cold storage of this kind does real work in the life sciences, and the line a buyer picks usually follows the material being kept. Refrigerated and frozen cabinets hold the reagents, media and consumables that cell culture depends on, so the daily routine of a molecular biology or a cell biology laboratory runs through them. Ultra-low temperature freezers preserve the cell lines, enzyme stocks and nucleic acid libraries that proteomics and genomics work accumulates over years, where a stable storage temperature protects sample integrity between experiments. Biostorage cabinets support biobanking and molecular diagnostics, where patient-derived material and controls must be held under documented conditions. This class of equipment is also used for vaccine and biologic storage in clinical and pharmaceutical settings, where the cold chain has to be maintained without interruption. The explosion-protected cabinets, in turn, serve laboratories handling solvents and other flammable reagents as part of sample preparation and formulation.
What is listed on Questpair?
The current catalogue is entirely in the used segment: 100 percent of the listings are used. That makes the practical question for a buyer one of condition and fit rather than new versus old, since every cabinet here is priced below new. Prices run from EUR 65 to EUR 3.250. The spread is wide because it covers both small benchtop refrigerators near the lower end and large upright or ultra-low freezers near the upper end, and the average of EUR 940 sits between the two without describing any single class.
Listings come from 5 verified suppliers and distributors, spread across 4 countries. Where a cabinet needs replacement shelving, seals or other components, parts can be sourced via Questpair. A warranty is often possible and is arranged in consultation for the specific listing, so the terms attach to the individual cabinet rather than to the brand as a whole. For documentation on a particular model, a buyer can contact Questpair, where specialists respond within the hour. The sensible order when reading these listings is to settle the temperature band and the storage volume first, since that choice separates a refrigerator from an ultra-low freezer, then weigh the specific cabinet's condition and price against the work it has to do.
Questpair review of Gram
Our take based on listings data and supplier feedback
Gram BioLine occupies a narrow and well-defined segment: temperature-controlled storage for laboratories and clinical settings, rather than general-purpose cooling. That focus is worth weighing against the alternatives, because a laboratory refrigerator differs from a domestic one in the things that matter for stored material, namely temperature uniformity, recovery after a door opening, and the logging a facility needs for its records.
The first benefit, that these cabinets are engineered for a specification rather than a kitchen, is visible in how the range is organised. The BioCompact II line covers smaller refrigerators and freezers for bench and under-counter use, the BioPlus and BioMidi lines move up to larger upright cabinets, and the BioUltra line addresses ultra-low temperature freezing for long-term sample storage. Separate from these sits the ExGuard range, which is built for storage of flammable material and carries explosion-protection construction. A buyer choosing between them is really choosing a temperature band and a volume, and the distinction between a laboratory refrigerator holding reagents at a few degrees and an ultra-low freezer holding material far below zero is the first thing to settle before price enters the picture.
The second benefit concerns condition. The present catalogue shows 100 percent of the listings as used, so every Gram BioLine unit currently on Questpair sits in the used segment. For a buyer this has a practical consequence. Used cold storage is listed below new, which is the price advantage to plan around, and warranty on any individual cabinet is arranged in consultation for that specific listing rather than assumed. Where a unit's internal temperature stability and door-seal condition matter to the work, those are questions to put against the individual listing.
The third benefit is the spread of the catalogue. Prices run from EUR 65 to EUR 3.250. That range is wide because it spans two quite different things: a small benchtop refrigerator sits near the bottom, while a large upright freezer or an ultra-low cabinet sits near the top. The average, at EUR 940, gives a rough sense of where the bulk of the smaller and mid-size cabinets land, though it should not be read as a typical price for any one class, since the mix of sizes pulls it in both directions.
Taken together, the three points describe a manufacturer whose value on a marketplace lies in matching a storage specification to a budget. Gram BioLine is not a broad instrument maker; it is a cold storage specialist, and the sensible way to read its listings is to fix the temperature band and the volume first, then read condition and price against the specific cabinet. Listings come from 5 verified suppliers and distributors, and parts for a cabinet can be sourced via Questpair where a unit needs them.

Frequently asked questions
Where can I find manuals and documentation for a Gram BioLine cabinet?
Documentation for a specific model can be requested through Questpair, where specialists respond within the hour. Because the catalogue is organised by product line rather than individual model, giving the exact cabinet you are looking at helps narrow down the right paperwork.
How much does a Gram BioLine refrigerator or freezer cost?
Listings range from EUR 65 to EUR 3.250, with an average of EUR 940. The low end covers small benchtop refrigerators and the high end covers large upright or ultra-low temperature freezers, so the price tracks the temperature band and storage volume.
What is the difference between refurbished and used Gram units?
Both are listed below the price of new equipment, which is the main distinction on Questpair. The practical difference comes down to the condition of the individual cabinet, so read the specific listing for its state before buying.
Is there a warranty on a used Gram cabinet?
A warranty is often possible and is arranged in consultation for the specific listing. Terms attach to the individual cabinet rather than to the Gram brand as a whole.
Are Gram BioLine cabinets suitable for clinical and research use?
Yes. The refrigerators and freezers hold reagents, media and consumables for molecular and cell biology, the BioUltra ultra-low freezers preserve cell lines and nucleic acid libraries for long-term storage, and biostorage cabinets support biobanking and molecular diagnostics where samples need documented conditions.
How long does a Gram laboratory refrigerator last?
Cold storage cabinets of this class are built for continuous operation over many years, and lifespan depends on how hard the compressor and door seals have been worked. When assessing a used unit, weigh its condition and any wear on shelving and seals against the work it has to do.
Can I get replacement parts for a Gram cabinet?
Parts such as replacement shelving and seals can be sourced via Questpair. Name the specific cabinet when enquiring so the correct components can be matched.
What are the alternatives to Gram for laboratory cold storage?
Other manufacturers of laboratory refrigerators, laboratory freezers and ultra-low temperature freezers cover the same temperature bands. What separates them is the configuration they specialise in, such as ATEX-certified storage for flammable material versus standard upright cabinets, so the comparison depends on the temperature band and volume you need.
How long is the lead time on a Gram listing?
Lead time depends on the individual listing and the supplier holding the cabinet, since availability varies across the 5 verified suppliers and distributors on Questpair. Contact Questpair for the status of a specific cabinet.
What is the difference between parts and spares for these cabinets?
The terms are used interchangeably here, both referring to components like shelving, seals and other replaceable items for a cabinet. All of these can be sourced via Questpair.
Do Gram cabinets ship internationally?
Listings come from verified suppliers and distributors across 4 countries, so cross-border supply is possible. Shipping arrangements depend on the individual supplier and listing.
Which product lines does Gram BioLine make and how do they differ?
BioCompact II covers smaller bench or under-counter refrigerators and freezers, while BioPlus and BioMidi are larger upright cabinets for higher volumes. BioUltra handles ultra-low temperature freezing, HELIX and the broader BioLine range extend into dedicated laboratory and clinical configurations, and ExGuard is an explosion-protected range for storing flammable substances.
Which types of Gram equipment are listed on Questpair and in what condition?
The listings cover laboratory refrigerators, laboratory freezers, biomedical freezers, refrigerated storage units, cold storage units and medical refrigerators. The catalogue is entirely used: 100 percent of the listings are used, so every cabinet is priced below new.
Why do some Gram listings cost so much more than others?
The gap follows the temperature band and the storage volume. A small benchtop refrigerator sits near EUR 65, while a large upright or an ultra-low temperature freezer sits near EUR 3.250, and the condition of the individual cabinet moves the price within that range.
