About Julabo

JULABO is a German temperature control instrument manufacturer founded by Gerhard Juchheim in Seelbach, Germany in 1967. The company was established to design and manufacture complete liquid temperature control instruments for science and research. It remains a privately held, Juchheim family-owned business, with no acquisition by an outside parent reported. Its primary categories are temperature control systems, refrigerated circulators, heating circulators, recirculating coolers, water baths and highly dynamic temperature control systems. On Questpair, these systems are listed by verified suppliers and distributors. The catalogue spans 297 units across 7 countries.

What JULABO circulators do in the lab?

A circulator moves temperature-controlled liquid through a bath or an external loop, holding a sample or a reactor at a set point. Refrigerated circulators cool and hold below ambient, heating circulators drive above it, and recirculating coolers remove heat from an instrument or a process. This work sits at the centre of a great deal of life sciences laboratory practice. Temperature control is the quiet requirement behind cell culture incubation loops, behind the thermal regulation of reactors in bioprocessing, and behind the cold chain that protects reagents during protein purification. A refrigerated circulator holding an enzyme reaction at a fixed temperature is doing the same work whether the field is called molecular biology or synthetic biology. Highly dynamic temperature control systems, which ramp quickly across wide windows, are also used for process development in biomanufacturing, where a reactor jacket must follow a programmed temperature profile. Water baths serve the everyday side of the same discipline, from sample thawing to the controlled incubations that immunoassay and microbiology work depend on. Across these uses the equipment is specified first by its temperature range and its stability, and the field it serves follows from that specification.

JULABO product lines on Questpair

The Questpair catalogue groups JULABO stock by the classes the company builds. Refrigerated circulators and heating circulators make up the core, and these are the units most buyers arrive looking for. Recirculating coolers appear for buyers cooling an instrument rather than a bath. Water baths cover the simpler heating and incubation tasks, and the highly dynamic temperature control systems sit at the high-performance end for fast, wide-range work. Among the listings that specify a type, these are the groups that recur. A buyer sourcing a matched pair, or replacing a known model, can filter within a class rather than reading the whole catalogue. Where documentation or a part is needed for a listed unit, it can be sourced via Questpair.

Condition, price and suppliers

The catalogue carries both new and used equipment. 57 percent of the listings are used. Used and refurbished circulators are listed below new pricing, and the practical question is condition rather than age, since the heater, pump and cooling assemblies are the parts that determine remaining service life. Prices run from EUR 150 to EUR 18.452. The lower figure reflects smaller baths and accessories; the upper figure reflects the dynamic temperature control systems. The average listing sits near EUR 4.637. Stock comes from 15 verified suppliers and distributors across 7 countries, so a buyer comparing two listings of the same model is often comparing two sellers as well. Warranty is often possible and is arranged in consultation for the specific listing, so the terms belong to the individual unit rather than to the catalogue as a whole.

Questpair review of Julabo

Our take based on listings data and supplier feedback

JULABO occupies a well-defined position in laboratory temperature control, and the Questpair catalogue reflects the breadth of that focus. The first thing a buyer notices is depth of stock: 297 listings from 15 verified suppliers and distributors across 7 countries. That volume matters because temperature control is rarely a one-off purchase. A lab running synthesis, crystallisation or reactor cooling often needs matching units, and a catalogue of this size makes it realistic to source more than one circulator from the same class without waiting on a single seller. The spread across suppliers also means a buyer is not locked into one availability window, which is a practical advantage when a failed bath halts a protocol.

The second benefit is the price range. Listings run from EUR 150 to EUR 18.452. That gap is not noise; it reflects the actual span of the product family. At the lower end sit smaller water baths and replacement accessories, and at the upper end sit the highly dynamic temperature control systems built for fast ramping across wide temperature windows. A buyer comparing a basic heating circulator against a presto-class dynamic system can see both in the same catalogue and judge the step up for themselves. The average listing sits around EUR 4.637, which gives a sense of where the bulk of refrigerated and heating circulators fall. Because that figure is refreshed against live stock, it tracks the current mix rather than a fixed list.

The third benefit is condition choice. 57 percent of the listings are used. Used and refurbished circulators are listed below new pricing, and for temperature control that trade-off is often reasonable: a well-maintained refrigerated circulator with intact cooling capacity can serve for years, and the pump and heater assemblies are serviceable components. A buyer weighing new against used should read the individual listing, since warranty is arranged in consultation for the specific unit rather than set centrally. New units carry no advantage here beyond being new; the deciding factors are the documented condition and the fit to the application.

What the catalogue does not tell you is reliability by model, and no marketplace figure substitutes for checking a unit's temperature stability specification against the protocol it will run. JULABO publishes stability figures for its circulators, and those are the numbers that decide whether a given system suits sensitive viscometry or routine bath heating. The Questpair listing is where condition, price and supplier meet; the specification is where the match to the work is confirmed. Taken together, the breadth of stock, the price span and the condition mix make the JULABO catalogue a workable starting point for sourcing temperature control, provided the buyer carries the application requirement into the individual listing.

**Deep stock of temperature control systems across conditions**

Questpair lists 297 JULABO units from 15 verified suppliers and distributors in 7 countries, covering refrigerated circulators, heating circulators and recirculating coolers.

**Price range spanning accessories to high-end systems**

Listings run from EUR 150 to EUR 18.452, so both a replacement bath and a highly dynamic temperature control system fall within the same catalogue.

**A mix of new and used units**

57 percent of the listings are used, which gives buyers a choice between lower-priced pre-owned circulators and new equipment.
