Jouan equipment

About Jouan

Jouan SA was a French manufacturer of centrifuges and laboratory sample preparation equipment, headquartered in Saint-Herblain, France. The company served academic, pharmaceutical, biotech, and clinical laboratories. In January 2004 it was acquired by Thermo Electron Corporation, which later became Thermo Fisher Scientific, and the Jouan name was folded into that larger organisation. Its primary categories were centrifuges, biological safety cabinets, ultra-low temperature freezers, and incubators. Associated product lines include Precision, NAPCO, Heto, Holten, and ALC. On the secondary market the equipment remains in regular use, which is why it appears as a defined group in the Questpair catalogue rather than as a handful of stray units.

Jouan centrifuges and sample preparation lines

Centrifuges were the core of what Jouan built, and centrifugation is the work most of its listed equipment does. The range covered benchtop models sized to sit alongside a bench and larger refrigerated and floor-standing systems built for higher volumes and temperature-sensitive work. These instruments spin samples to separate components by density, the step that stands behind cell culture harvesting, protein purification, and the clarification of samples ahead of molecular biology and proteomics workflows. A refrigerated centrifuge holds a set temperature through a run, which is what makes it suitable for the handling of live cells and labile proteins in a cell culture or protein purification setting.

The sample preparation equipment extends past the centrifuge itself. Jouan's categories reached into biological safety cabinets, ultra-low temperature freezers, and incubators, the surrounding hardware a laboratory needs to prepare, process, and store biological material. Biological safety cabinets support work in microbiology and cell culture by containing aerosols during handling. Ultra-low temperature freezers hold samples for long-term biobanking in genomics and molecular diagnostics, where the integrity of stored nucleic acids depends on a stable deep-cold environment. Incubators maintain the controlled conditions that cell culture and microbiology both require. The product lines carried through acquisition, Precision, NAPCO, Heto, Holten, and ALC, each sat within this broader life sciences range rather than in centrifugation alone.

Because the line is discontinued, matching an existing instrument matters more than it does for a current product. Rotors, buckets, and chamber accessories were specific to the model they were built for, so the practical question for a returning Jouan user is whether a given listing carries the configuration already in service. Parts, where a unit needs them, can be sourced via Questpair.

What the Jouan listings on Questpair cover

The catalogue holds 72 Jouan items supplied by 8 verified suppliers and distributors, reaching buyers across 6 countries. That geographic spread widens the pool of models and conditions available at any given moment, which is useful for a line no longer in production.

Prices run from EUR 89 to EUR 3.835. The average listing sits at EUR 708, with the lower end covering small benchtop units and the upper end covering larger refrigerated and floor-standing systems. Every unit is used; 100 percent of the listings are used. That condition is the direct reason the prices sit below those of comparable new equipment, and it is the main thing a buyer weighs when choosing a used Jouan over a current instrument from another maker.

Condition and configuration vary from one seller to the next, so the individual listing is where the real detail lives. Where a warranty is wanted, it is often possible and is arranged in consultation for the specific listing. For documentation or parts, a buyer can contact Questpair, and specialists respond within the hour.

Questpair review of Jouan

Our take based on listings data and supplier feedback

Jouan equipment appears on the secondary market as a legacy line rather than a current catalogue, and the way it is listed reflects that. The first thing a buyer sees is the breadth of centrifugation hardware on offer. The Questpair catalogue holds 72 Jouan items, and the bulk of them are centrifuges in the benchtop and floor-standing formats that defined the company before its 2004 absorption into Thermo Electron. For a lab that already runs Jouan rotors and buckets, or that wants a known spin profile without paying for a current-generation instrument, this depth of a single discontinued maker is worth noting. Sourcing matters here because parts and accessories were format-specific, and a catalogue that groups the maker in one place makes it easier to match a replacement to an existing setup. Parts, where they are needed, can be sourced via Questpair.

The second point is price. Listings range from EUR 89 at the low end to EUR 3.835 at the top, with an average of EUR 708. That spread covers bare units and small benchtop models at the bottom and larger refrigerated or floor-standing systems at the top. Every unit in the catalogue is used, which is the whole explanation for prices that sit below what a comparable new instrument costs; 100 percent of the listings are used. A buyer weighing a used Jouan against a new equivalent is trading the price difference against the fact that this is older, discontinued hardware, and the sensible way to assess any single unit is to read the individual listing. Where a warranty is a concern, that is arranged in consultation for the specific listing rather than set centrally.

The third point is supply. The 72 items come from 8 verified suppliers and distributors spread across 6 countries. For a discontinued line this spread is more useful than it looks, because it raises the chance that a specific rotor, chamber size, or configuration is actually in stock somewhere rather than available only in theory. It also means condition varies between sellers, so comparing two listings of nominally the same model is a real exercise rather than a formality.

Taken together, the Jouan listings serve a specific buyer: one who knows the line, needs a centrifuge or a sample preparation unit that behaves the way a Jouan does, and is comfortable buying used hardware from a maker that no longer produces under its own name. The catalogue does not pretend otherwise. It presents the instruments, the prices, and the sellers, and leaves the judgement on any individual unit to the listing itself.

**Centrifuge depth from a single maker**

The catalogue carries Jouan centrifugation equipment across benchtop and floor-standing formats, with 72 items drawn from 8 verified suppliers and distributors.

**Prices set well below new**

Listings run from EUR 89 to EUR 3.835, with the average sitting at EUR 708, because every unit is offered used rather than new.

**European supply spread**

Stock reaches the buyer from suppliers across 6 countries, which widens the pool of available models and conditions.
