Ohaus equipment

About Ohaus

Ohaus is an American precision weighing and laboratory equipment manufacturer founded in 1907, when Gustav and Karl Ohaus began as a scale repair business in Newark, New Jersey, before incorporating as Newark Scale Works in 1914. The company is headquartered in Parsippany, United States, and has been part of Mettler-Toledo International Inc. since its acquisition in 1990. Its core output is balances and scales across the full precision range, from analytical models reading to four decimal places down to rugged portable and industrial platforms. Alongside the weighing instruments, Ohaus produces moisture analysers, laboratory centrifuges, lab mixers and vortexers, hotplates and stirrers, and pH and water analysis meters. The balances anchor gravimetric analysis, the quantitative weighing step that sits under almost every analytical protocol. On Questpair, Ohaus equipment is listed by verified suppliers and distributors across 7 countries.

Ohaus balance and scale series

The weighing range is organised into named series that map onto distinct levels of precision and duty. The Explorer and Pioneer lines cover analytical and precision balances for the laboratory bench, where readability to four decimal places supports gravimetric analysis and the preparation of standards and buffers. The Adventurer sits a step below as a general precision balance, while the Scout and Navigator lines are portable units built for field and teaching use. At the heavier end, the Ranger and Defender series are industrial scales, and the Frontier name covers centrifuges rather than balances. Older mechanical weighing survives in the Triple Beam, still listed where a laboratory wants a balance with no electronics to maintain. These families recur throughout the catalogue, so a buyer who knows the series name can filter directly to the duty class they need.

Ohaus in biotechnology and life sciences work

Within life sciences, the weighing instruments do the gravimetric analysis that underpins molecular biology and cell culture: an analytical balance reading to four decimal places is what weighs out reagents, media components and the salts behind every buffer. The moisture analysers determine solids content by loss on drying, a routine check in formulation and in quality control of biological preparations. The laboratory centrifuges handle sample preparation, pelleting cells and spinning down lysates ahead of protein purification. The vortexers and mixers resuspend those pellets and homogenise samples, and the hotplate stirrers hold and heat solutions during the same preparation steps. An Ohaus analytical balance for reagent weighing and an Ohaus benchtop centrifuge for cell pelleting are two instruments a molecular biology bench uses daily, which is why this maker appears across general wet-lab setups rather than in one specialism.

What is listed on Questpair?

Ohaus accounts for 2001 listings on the Questpair catalogue, offered by 18 verified suppliers and distributors across 7 countries. 56 percent of the listings are used. Prices range from EUR 1 to EUR 14.032. That spread reflects the span of the range itself, from basic portable scales and accessories at the low end to new analytical and industrial models at the high end, so the brand average of EUR 1.711 says less than the condition and series of an individual advert. Where a manual or documentation is needed for an older model, that can be requested through Questpair, and replacement parts can be sourced the same way. Warranty is not set centrally; it is arranged in consultation for the specific listing, which is the detail a buyer weighing a used against a new unit should check on the advert itself.

Questpair review of Ohaus

Our take based on listings data and supplier feedback

Ohaus occupies a clear position on the Questpair catalogue: a weighing specialist whose range reaches well beyond the balance into general bench equipment. That breadth is the first thing the listings bear out. Analytical balances from the Explorer and Pioneer lines, reading to four decimal places, sit in the same brand catalogue as the Scout portable models and the Defender and Ranger industrial scales. A laboratory standardising on one maker can therefore cover microgram analytical work and heavy platform weighing without crossing brands, and the moisture analysers, centrifuges, vortexers and stirrers extend that into sample preparation and routine bench work. For a buyer who values a single point of familiarity across an instrument fleet, that span is the practical argument.

The condition split is the second point worth weighing. Of the listings, 56 percent are used. That is a substantial second-hand pool for a brand whose balances are long-lived instruments, and it matters because a used Scout or Adventurer carries most of its working life ahead of it when the mechanism is sound. Used and refurbished units are listed below new prices, so the condition field is where a fixed budget does its real work. A buyer should read each listing on its own terms rather than the brand average, since a bare portable scale and a fully specified analytical balance sit at opposite ends of what Ohaus makes.

Price is the third, and it follows directly from that range. Listings run from EUR 1 to EUR 14.032. The low end reflects accessories and basic portable scales; the high end reflects top analytical and industrial models in new condition. The average sits at EUR 1.711, which is less useful than the spread itself, because the catalogue is not one product with a central price but a dozen series at very different points. What the number does tell a buyer is that an entry-level mechanical Triple Beam and a loaded Explorer are not competing for the same budget line.

Supply underpins all three. 18 verified suppliers and distributors list Ohaus equipment across 7 countries, which gives a buyer more than one source for a given model and some room to compare condition and price between near-identical listings. Where documentation or a manual is needed for an older Ranger or Defender, that can be requested through Questpair, and parts can be sourced the same way. Warranty is not fixed centrally; it is arranged in consultation for the specific listing, which again points the buyer back to the individual advert rather than a brand-wide promise. Taken together, the Ohaus presence on Questpair reads as a broad, condition-varied catalogue best navigated listing by listing rather than by reputation alone.

**Balances across every precision class**

The Ohaus listings span analytical balances reading to four decimal places alongside portable and industrial scales, so a single maker covers bench weighing from microgram work to heavy platform loads.

**A catalogue weighted toward used stock**

Of the listings on Questpair, 56 percent are used, which gives a buyer working to a fixed budget a genuine second-hand pool rather than new units alone.

**A wide price spread from 18 suppliers**

Prices run from EUR 1 to EUR 14.032 across verified suppliers and distributors, so an entry-level Scout and an Explorer analytical model sit in the same catalogue.
