About Scientific Industries

Scientific Industries is an American benchtop laboratory equipment manufacturer, incorporated in 1954 as a Delaware corporation to design, manufacture and market benchtop instruments, most notably inventing the vortex mixer. The company is headquartered in Bohemia, New York, and trades independently on the OTCQB under the ticker SCND, with no parent company. Its catalogue spans vortex mixers, benchtop mixers and shakers, rotators and rockers, refrigerated and shaking incubators, magnetic stirrers, pharmacy and laboratory balances and scales, force gauges, moisture analysers and bioprocessing systems. The best known product lines are the Vortex-Genie mixers, the Genie range of shakers and rotators, the Torbal balances and scales, and specialised units such as the Roto-Shake Genie, the Magstir Genie and the MicroPlate Genie. Much of this equipment supports molecular biology and cell culture work, where sample mixing, incubation and weighing are routine steps. On Questpair, 190 of the 226 listings for this maker are used, offered by 12 verified suppliers and distributors across 5 countries.

Scientific Industries product lines

The Vortex-Genie line is the instrument the company is known for, and vortex mixing underpins sample preparation across molecular biology and microbiology, from resuspending a pellet to homogenising a lysate. The MicroPlate Genie extends the same action to multiwell plates, which matters for immunoassay and high-throughput screening where every well must be agitated evenly. The Roto-Shake Genie and the Magstir Genie cover rotation and magnetic stirring, both standard in reagent preparation and protein purification, where gentle continuous mixing keeps a solution homogeneous without foaming. Refrigerated and shaking incubators serve cell culture and bacterial growth, holding a controlled temperature while agitating a flask, and they are also used for enzyme reactions that need steady conditions over hours. Torbal balances and scales handle the weighing side, from pharmacy compounding to gravimetric analysis in an analytical lab. Force gauges and moisture analysers round out the range, covering mechanical testing and moisture content determination. The bioprocessing systems reach further into biomanufacturing, where single-use mixing and monitoring support cell culture at larger scale. Across these lines the common thread is benchtop format: instruments sized to sit on a lab bench and run a routine step reliably rather than occupy a dedicated room.

What Scientific Industries equipment is listed on Questpair?

The listings concentrate where the used supply is deepest, which for this maker means the mixing and shaking lines. Among the listings that specify a type, the Genie family and the vortex mixers appear most often, with incubators, stirrers and Torbal balances filling out the rest. Prices run from EUR 26 to EUR 4.733. The average sits around EUR 407, which places most of the catalogue well below the cost of a large shaking incubator and above that of a bare mixer. 85 percent of the listings are used. Used and refurbished units are listed below new pricing, and that price gap is the clearest reason a buyer looks at the secondary market for a brand whose mixers turn over steadily. Where a warranty matters, it is arranged in consultation for the specific listing rather than set centrally, so the condition and the terms are read at the level of the individual unit. Parts can be sourced via Questpair, and for manuals or documentation a buyer can contact Questpair, where specialists respond within the hour. The equipment itself comes from 12 verified suppliers and distributors in 5 countries, so a buyer comparing two listings of the same Vortex-Genie is often comparing sellers as much as instruments.

Questpair review of Scientific Industries

Our take based on listings data and supplier feedback

Scientific Industries occupies a specific place in the laboratory equipment market: it is the firm that invented the vortex mixer, and that single instrument class still anchors its catalogue. For a buyer, the practical consequence is depth in one area rather than breadth across unrelated fields. The Vortex-Genie line, and the wider Genie family of shakers and rotators, covers the kind of sample mixing that recurs in almost every wet lab, which is why used examples circulate in volume. On Questpair, 190 of the 226 listings are used, so a lab buying a second mixer or replacing a worn one is buying into a well-supplied secondary market rather than a thin one.

The benefit that follows from the company's range is the ability to fit out a bench from one maker. The catalogue is not confined to mixing. It reaches into rotators and rockers, refrigerated and shaking incubators, magnetic stirrers, Torbal pharmacy and laboratory balances, force gauges, moisture analysers and bioprocessing systems. A procurement manager equipping a new bench can therefore source a shaking incubator for cell culture, a stirrer for reagent preparation and a balance for gravimetric work without juggling several manufacturers. Whether that consolidation matters depends on the lab, but for anyone who values a single point of familiarity across instrument classes, the breadth is real. On Questpair the equipment comes from 12 verified suppliers and distributors across 5 countries, which spreads the sourcing rather than tying it to one seller.

The third point a buyer weighs is price, and here the spread is wide. Listings range from EUR 26 to EUR 4.733, with an average around EUR 407. The low end reflects standalone vortex mixers and small accessories; the high end reflects shaking incubators and bioprocessing instruments, which are larger and more complex. That range means the brand is not a single price tier but a set of them, and a buyer should read the condition and the specification of an individual listing rather than the brand average. 85 percent of the listings are used. Used and refurbished units sit below new pricing, which is the one firm claim worth making when comparing the two; beyond that, warranty is arranged in consultation on the specific listing, so the comparison is best made listing by listing rather than across the brand as a whole.

Taken together, the three benefits point to the same buyer: one who needs reliable benchtop instruments, values a well-stocked used market for the mixing lines, and wants to compare condition and price at the level of the individual unit. The Torbal balances and the shaking incubators extend that logic beyond mixing into weighing and incubation, so the brand supports more than the instrument it is known for. For a lab building out a general-purpose bench, that combination of a deep used supply and a range that covers several routine tasks is what makes Scientific Industries worth checking against its competitors.

Vortex mixers from the inventor

Scientific Industries incorporated in 1954 and invented the vortex mixer, and the Vortex-Genie line remains on Questpair where 190 of the 226 listings are used units priced below new.

One maker, the full benchtop range

The catalogue runs from magnetic stirrers and rotators to refrigerated shaking incubators and Torbal balances, so a lab fitting out a bench can source several instrument classes from a single manufacturer across 12 verified suppliers and distributors.

Prices that span entry to instrument

Listings range from EUR 26 to EUR 4.733, covering a standalone vortex mixer at one end and a shaking incubator at the other.
