Teledyne Isco equipment

About Teledyne Isco

Teledyne ISCO is an American laboratory and environmental instrument manufacturer specializing in chromatography, syringe pumps, water and wastewater samplers, and flow meters. The company was founded in 1958 as ISCO, Inc. by Dr. Robert Allington, who grew it from his garage in Lincoln, Nebraska into a major instrument maker. In June 2004 it was acquired by Teledyne Technologies Incorporated and became Teledyne ISCO, retaining its Lincoln base. Its primary categories span flash chromatography systems, preparative HPLC, syringe pumps, reciprocating pumps, water and wastewater samplers, open-channel flow meters, and fraction collectors. The best-known product families are CombiFlash, RediSep, ACCQPrep, Foxy, ReaXus, and the D-Series. The brand is unusual in serving both the analytical bench and the environmental field from a single catalogue. On Questpair, its instruments are listed exclusively as used units by verified suppliers and distributors.

The chromatography side of the range begins with CombiFlash, the automated flash chromatography platform, used with RediSep disposable cartridges that set the stationary phase for a given separation. Flash chromatography is the routine purification step in synthetic chemistry, where a crude reaction mixture is resolved into its components, and the automated form removes the manual fraction-watching that the technique once demanded. The ACCQPrep line carries the same logic into preparative HPLC, the higher-resolution chromatography used to isolate milligram-to-gram quantities of a single compound. Foxy fraction collectors sit at the end of either workflow, directing the eluent into individual vessels as each peak comes off the column. Together these support small-molecule purification, natural-product isolation, and the compound libraries that feed medicinal chemistry and proteomics sample preparation.

The pumping lines serve a different need. D-Series syringe pumps deliver a continuous, pulse-free flow at high pressure, which makes them suited to supercritical fluid chromatography and extraction, to pump calibration, and to any molecular biology or formulation protocol that cannot tolerate a pressure ripple. ReaXus reactant feed pumps are built for metering reagents into continuous-flow and automated reaction systems, a pattern now common in flow chemistry and in bioprocessing feed control. Reciprocating pumps round out the delivery range for higher-throughput, lower-pressure duties.

The environmental lines stand apart from the laboratory instruments. Water and wastewater samplers collect timed or flow-proportional samples autonomously in the field, feeding molecular diagnostics and microbiology workflows that test for contaminants and pathogens, and the open-channel flow meters measure discharge in sewers, culverts, and natural watercourses. These instruments are the backbone of regulatory water monitoring and are also used for wastewater-based epidemiology, where sampled effluent is screened for genetic markers of disease across a population.

What Teledyne ISCO equipment is listed on Questpair?

The Questpair catalogue holds 74 listings for this maker, offered by 6 verified suppliers and distributors across 4 countries. 100 percent of the listings are used. Prices run from EUR 65 to EUR 26.754, with an average near EUR 10.273. That range mirrors the breadth of the product families: the low end covers cartridges, fraction-collector racks, and accessories, while the high end reflects complete preparative HPLC and automated flash systems. A buyer comparing two listings of the same model can weigh condition, configuration, and included accessories across more than one source.

Where a unit needs replacement parts, these can be sourced via Questpair. Documentation and manuals can be requested through Questpair, with specialists responding within the hour. Warranty is often possible and is arranged in consultation for the individual listing, so the terms attach to the specific instrument rather than to the brand as a whole. Because every listing here is a used unit, the comparison a buyer makes is between configurations and conditions rather than between new and used, and the individual listing page carries the detail each decision turns on.

Questpair review of Teledyne Isco

Our take based on listings data and supplier feedback

Teledyne ISCO occupies an unusual position among instrument makers, bridging the analytical laboratory and the environmental field with a catalogue that runs from benchtop purification systems to open-channel flow meters sited in sewers and streams. For a buyer scanning the Questpair listings, three characteristics shape what is worth knowing.

The first is the depth of the chromatography and purification range. The CombiFlash and RediSep names are well established in automated flash chromatography, the technique that separates reaction mixtures into their components on disposable silica cartridges, and the ACCQPrep line extends the same approach into preparative HPLC for larger-scale isolation. Foxy fraction collectors round out the workflow by capturing eluted peaks into individual tubes. A laboratory moving from manual column work to automated purification tends to buy these as a set rather than in isolation, so a used CombiFlash paired with a RediSep cartridge format and a Foxy collector reconstructs a complete purification bench at a fraction of new cost. The Questpair catalogue reflects that pattern, with purification instruments forming a visible share of what is offered.

The second characteristic is the syringe pump engineering. The D-Series syringe pumps and the ReaXus reactant feed pumps deliver continuous, pulseless flow at pressures that reciprocating pumps struggle to hold steady. That matters in supercritical fluid work, in high-pressure reaction feeding, and in any application where a pressure ripple would disturb a measurement or a reaction. These pumps have a long service life, which is part of why used units reach the secondary market in working condition and why a buyer can reasonably consider one. Where warranty is a concern, it is arranged in consultation for the specific listing rather than offered uniformly, so the individual listing is the place to check.

The third characteristic is the environmental monitoring heritage, which sets Teledyne ISCO apart from makers that stay inside the laboratory. The water and wastewater samplers and open-channel flow meters are field instruments, built for autonomous operation in treatment plants and watercourses. They appear less often on a laboratory procurement list but are central for environmental consultancies and municipal utilities, and their presence in the catalogue signals that this brand serves a wider audience than a chromatography specialist alone.

Across the catalogue, every one of the current listings is a used instrument, which concentrates the decision on condition and configuration rather than on the new-versus-used trade-off. Prices range widely, from EUR 65 at the accessory and consumable end to EUR 26.754 for complete high-end systems, with an average around EUR 10.273. That spread reflects the range of the product families themselves, from a bare fraction collector to a fully configured preparative HPLC. The listings come from 6 verified suppliers and distributors across 4 countries, giving a buyer more than one source to compare on a given model. Parts, where a unit needs them, can be sourced via Questpair, and documentation requests reach specialists who respond within the hour.
