Hoefer equipment

About Hoefer

Hoefer is an American life science instrumentation manufacturer specialising in gel electrophoresis, blotting and imaging equipment. The company was founded in San Francisco in 1967 by Peter and Jacqueline Hoefer, who built it as a pioneer in gel electrophoresis instrumentation. Since November 2003 it has been part of Harvard Bioscience. Its primary categories are gel electrophoresis equipment, protein and nucleic acid blotting systems, power supplies, imaging and visualisation systems, and laboratory consumables and reagents. Electrophoresis separates proteins and nucleic acids by size and charge through a gel matrix, and the blotting step that follows transfers those separated molecules onto a membrane for detection. This places Hoefer's hardware at the centre of molecular biology and proteomics, where protein electrophoresis and Western blotting are everyday steps, and where nucleic acid electrophoresis underpins much of genomics sample analysis. On Questpair, 76 Hoefer items are listed by verified suppliers and distributors across 4 countries.

The vertical electrophoresis units are the backbone of the range. The SE250 and SE260 are compact mini formats for fast protein runs, the SE600 is the large-format tank for preparative and high-resolution gels, and the MiniVE and Chroma systems sit alongside them for routine protein work. These units are the ones most often reached for in protein electrophoresis and in the gel step ahead of a Western blot.

Horizontal, or submarine, electrophoresis is covered by the HE33 and HE99 tanks, which run agarose gels for nucleic acid separation, the standard method behind restriction analysis and much of molecular diagnostics sample work. The transfer family, the TE22, TE42, TE62, TE70 and TE77 units, handles the blotting that follows a gel, moving proteins or nucleic acids onto a membrane for immunoassay-based detection and hybridisation. The IEF100 covers isoelectric focusing, a first-dimension separation used in proteomics, and the ULTima systems provide imaging and visualisation of the finished gel or blot. Power supplies run the whole set, and consumables and reagents, plates, combs, buffers and membranes, keep an existing bench supplied. A buyer fitting out a complete workflow can match a separation unit, a transfer unit, a power supply and an imaging system from within one maker's range.

How does condition break down across the Hoefer listings?

41 percent of the listings are used. Used and refurbished Hoefer units are listed at lower prices than new ones, and that price difference is the main thing separating the two on the catalogue. Prices run from EUR 51 to EUR 30.143, with an average near EUR 1.706. The low end reflects consumables, replacement plates and smaller power supplies, while the high end reflects complete imaging setups and large-format systems. Because these are largely electromechanical instruments, a used tank or transfer unit is a practical choice; the judgement sits with the specific listing. Warranty is often possible and is arranged in consultation for the individual listing rather than as a fixed term.

Where can Hoefer parts and support be arranged?

Parts for Hoefer equipment, replacement plates, combs, electrode assemblies and buffers, can be sourced via Questpair. Manuals and documentation can be requested through Questpair as well, where specialists respond within the hour. Buyers weighing a new unit against a used one should compare the individual listings directly, since warranty on either is set per listing rather than centrally. The 7 verified suppliers and distributors offering Hoefer across 4 countries make it worth checking current stock for a specific model before committing to a particular configuration.

Questpair review of Hoefer

Our take based on listings data and supplier feedback

Hoefer occupies a specific corner of the laboratory: the separation and transfer of proteins and nucleic acids by electrophoresis. For a buyer the first benefit worth testing is the depth of the range, and the Questpair listings bear it out. The vertical slab units appear in their familiar forms, from the compact SE250 and SE260 through the SE600 large-format tanks, alongside the MiniVE and Chroma systems. Horizontal units and the HE33 and HE99 submarine tanks cover nucleic acid work, and the TE22, TE42, TE62, TE70 and TE77 transfer units handle the blotting step that follows a gel. This is not a maker that sells a single device under many names; the catalogue reflects a product family built out over decades around one method, which matters when a lab wants matching components rather than a mixed bench.

The second benefit is the split between new and used stock. 41 percent of the listings are used. That share gives a lab two genuine routes to the same equipment. A group standardising on the SE250 for routine mini-gels can often find a used unit, while a facility that needs a documented new instrument for a regulated workflow has that option in the same catalogue. Because Hoefer units are largely electromechanical, tanks, combs, plates and electrode assemblies, a used unit is a reasonable proposition where it would be riskier with a complex analyser. Warranty on any individual listing is arranged in consultation for that listing rather than set as a blanket term, so the condition judgement sits with the specific unit in front of the buyer.

The third benefit is price spread. Listings run from EUR 51 to EUR 30.143, with an average around EUR 1.706. The lower end reflects consumables and reagents, replacement plates and the smaller power supplies; the upper end reflects complete imaging and visualisation setups and large-format systems with their power units. A buyer can therefore approach Hoefer either as a source of parts and consumables to keep an existing bench running, or as a supplier of a full electrophoresis and blotting workflow, and the catalogue supports both without forcing a jump to new-only pricing.

Two practical notes temper the picture. The number of verified suppliers and distributors offering Hoefer on Questpair is 7, spread over 4 countries, so availability of a specific model is worth checking against current stock rather than assumed. And the imaging side of the range, built around the ULTima systems, is a smaller presence than the electrophoresis and blotting hardware, so a lab looking primarily for documentation and visualisation may find fewer options than one buying tanks and power supplies. For the core task Hoefer was built for, protein and nucleic acid separation and transfer, the listed range is coherent and well matched to the method.

**Deep bench in gel electrophoresis instrumentation**

Hoefer has built vertical slab units, blotting tanks and power supplies since 1967, and the SE, TE and HE series that defined protein and nucleic acid separation show up across the 76 items currently listed.

**Both new and used routes to the same series**

With 45 new units alongside 31 used ones, a buyer can fit out a mini SE250 bench or an SE600 large-format run without committing to new-only pricing.

**Priced across the full range of a Hoefer workflow**

Listings run from EUR 51 to EUR 30.143, which spans a single consumable up to a complete imaging and power setup from verified suppliers and distributors in 4 countries.
