About Stuart

Stuart is a British benchtop laboratory equipment manufacturer headquartered in Stone, United Kingdom. The brand is operated under Cole-Parmer, a subsidiary of Antylia Scientific formerly known as Cole-Parmer Instrument Company. Antylia Scientific is owned by Brookfield Asset Management and CDPQ, which acquired it in 2025. The product portfolio centres on the thermal, mechanical, and sample-handling steps of bench work rather than on analytical instrumentation. Much of the range carries a BioCote-protected finish, an antimicrobial surface treatment applied to the benchtop housings. On Questpair, 200 Stuart items are listed from 12 verified suppliers and distributors across 6 countries.

Stuart product lines and instrument classes

The Stuart range groups into a handful of functional families. Hotplate stirrers and magnetic stirrers handle heating and mixing at the bench, while shakers and rockers provide the agitation step for cultures and staining protocols. Laboratory incubators and block heaters cover controlled-temperature work, and water baths supply the wet thermal environment for sample conditioning. These heating and agitation instruments are also used for cell culture work, where controlled temperature and gentle mixing are routine, and the shakers and rockers support electrophoresis gel staining and membrane washing in molecular biology workflows.

Melting point apparatus determines the melting range of a solid sample, a standard check in organic synthesis and in quality control for pharmaceutical and chemical labs. Water stills, including the Aquatron and Merit lines, produce purified water for reagent preparation. Rotary evaporators remove solvent from a sample under reduced pressure, a core step in sample preparation across analytical chemistry and natural-product work. Blood tube rotators keep blood and other suspensions mixed to prevent settling, a task common in haematology and in clinical sample handling. Colony counters assist the enumeration step in microbiology, where visible bacterial colonies on a plate are tallied after incubation.

Several of these classes carry direct relevance to life sciences work. The incubators and shakers support cell culture and microbiology; the block heaters serve the denaturation and ligation steps that precede molecular diagnostics and sample preparation for genomics; and the rotary evaporators handle solvent concentration in protein purification and metabolite extraction. A buyer searching for a Stuart orbital shaker for bacterial culture, a Stuart block heater for sample incubation, or a Stuart melting point apparatus for purity testing will find the equipment described in terms a specialist uses day to day.

On Questpair: condition, price and supply

The Stuart listings on Questpair are overwhelmingly second-hand. 99 percent of the listings are used. That shapes how a purchase works in practice: the equipment is bought as listed, from a verified supplier or distributor, with terms set per item rather than across the brand. Warranty is often possible and is arranged in consultation for the specific listing.

Prices range from EUR 47 to EUR 6.939, with an average near EUR 569. The lower end covers simple devices such as blood tube rotators and basic stirrers, while the upper end reaches the water stills and rotary evaporators. Used and refurbished units are listed below the price of new equivalents, which is the practical reason this equipment circulates on the marketplace.

Supply is spread across 12 verified suppliers and distributors in 6 countries, so a buyer seeking a particular instrument class usually has more than one listing to compare. Where a listed unit needs a component, parts can be sourced via Questpair, and documentation requests reach specialists who respond within the hour. The Questpair catalogue for Stuart is the place to compare the available benchtop units across these categories, from the smallest rotator through to the larger distillation and evaporation equipment.

Questpair review of Stuart

Our take based on listings data and supplier feedback

Stuart occupies a specific niche within laboratory supply: benchtop instruments that handle the routine mechanical and thermal steps of bench work rather than the analytical measurement itself. The catalogue on Questpair reflects that scope. Rather than a single flagship product, the listings spread across hotplate stirrers, incubators, block heaters, water baths, and melting point apparatus, which is the first thing worth weighing when assessing the brand through this marketplace.

The breadth matters because it changes how a lab buyer approaches the listings. A procurement decision for Stuart is rarely about one device in isolation. A lab fitting out a wet bench may need a magnetic stirrer, a block heater, and a water bath from the same maker, and the Questpair catalogue carries all three classes under one brand. 200 items are currently listed, which gives enough depth across categories that a buyer comparing, say, two incubator options against a shaker purchase can do so within a single supplier search. These systems share the benchtop footprint and the BioCote-protected finish that runs through much of the Stuart range, so a lab standardising on one brand gains consistency in form factor and cleaning protocol.

On pricing, the figures give a clear picture of what the marketplace offers. Listings range from EUR 47 to EUR 6.939, with an average near EUR 569. That spread reflects the gap between a simple blood tube rotator or a basic stirrer at the low end and a water still or rotary evaporator at the upper end. The wide band is useful for a buyer with a fixed budget, because it means the brand is represented at several price points rather than clustered at one. Used and refurbished units are listed below new prices, and that price difference is the practical reason most of this equipment reaches a second lab.

Condition is the third point, and here the catalogue is weighted heavily one way. 99 percent of the listings are used. For a lab buyer, that concentration is neither good nor bad in itself, but it does shape expectations: a Stuart purchase on Questpair is almost always a second-hand transaction, and the sourcing, inspection, and warranty questions that come with used equipment apply. Warranty is often possible and is arranged in consultation for the specific listing, so the terms are set per item rather than uniformly across the brand.

Supply is distributed rather than concentrated. The 200 items come from 12 verified suppliers and distributors across 6 countries, which gives a buyer more than one route to a given instrument class. For a lab in continental Europe seeking a Stuart water bath or incubator, that cross-border supply base reduces dependence on any single seller. Parts can be sourced via Questpair where a listed unit needs a component, and documentation requests reach specialists who respond within the hour. Taken together, the brand reads on this marketplace as a practical benchtop choice with a deep used inventory and a price range that accommodates both the smallest rotator and the larger distillation and evaporation equipment.
