NanoEnTek equipment

About NanoEnTek

NanoEnTek is a South Korean manufacturer of life science laboratory equipment and in vitro diagnostic medical devices, headquartered in Seoul. The company builds instruments for cell analysis, imaging and point-of-care diagnostics, with a product base rooted in miniaturised fluidics and lab-on-a-chip design. In September 2023 Apluslife Co. Ltd. acquired a 39.64 percent controlling stake, and the firm remains publicly listed on KOSDAQ. Its catalogue runs across automated cell counters, fluorescence immunoassay analysers, live-cell imaging systems, point-of-care diagnostic devices, disposable hemocytometers and lab-on-a-chip consumables. The best-known lines are the ADAM and EVE automated cell counters, the FREND fluorescence immunoassay analyser, the JuLI live-cell imaging series and the NEON gene delivery system. Several of these instruments do cell counting and cell culture work directly, which is where the brand is most widely used. The sections below set out the main lines and what is currently listed on Questpair.

ADAM, EVE and the automated cell counter lines

The ADAM and EVE series are automated cell counters, and they do the routine cell counting that opens most cell culture protocols: measuring concentration and viability in a suspension before seeding or passaging. An automated counter removes the manual hemocytometer step, which is slower and more variable between operators. These instruments are small enough to sit beside a biosafety cabinet, and their disposable counting chips keep cross-contamination out of shared equipment. In practice they serve molecular biology and cell biology groups preparing samples for transfection, assay setup or downstream genomics, where a consistent starting cell number affects every later result. The counting function also feeds into bioprocessing and cell culture scale-up work, where viable cell density is tracked across a growth run. Within this class the units differ mainly in whether they count fluorescently stained or brightfield images, and in the chip format they accept, so the listing specification is the thing to read rather than the series name alone.

JuLI live-cell imaging and the NEON gene delivery system

The JuLI series provides live-cell imaging from inside an incubator, recording confluence, migration and morphology over hours or days without removing the plate. This suits proliferation assays, wound-healing and scratch studies, and time-lapse work in cell imaging where manual observation would disturb the culture. The NEON system is a gene delivery platform, electroporating cells to introduce nucleic acids, which places it in transfection and gene editing workflows across molecular biology and synthetic biology labs. The two instruments address different stages: one watches cells grow and respond, the other introduces material into them. Both are used in cell culture environments and both depend on consumables matched to the instrument, so compatibility with available chips, tips or cuvettes is worth confirming against the individual listing.

FREND and point-of-care diagnostics

The FREND analyser is a fluorescence immunoassay reader built for point-of-care testing. It reads a disposable cartridge and returns a quantitative immunoassay result, which places it in molecular diagnostics and clinical chemistry rather than open research. The instrument is compact and cartridge-driven, so the operator loads a prepared sample and reads a result without separate assay steps. This class of device is also used for protein and biomarker measurement where a central laboratory analyser would be too large or too slow for the setting. Because the readout depends on the matched cartridge, the consumable supply is part of what a buyer is committing to.

Read each listing on its own specification, since condition, included consumables and configuration vary across the catalogue.

Questpair review of NanoEnTek

Our take based on listings data and supplier feedback

NanoEnTek occupies a specific corner of the life sciences instrument market: cell analysis and point-of-care diagnostics, built around miniaturised fluidics rather than large bench systems. For a buyer weighing the brand on Questpair, three patterns in the catalogue are worth reading closely.

The first is the weight of automated cell counters in the available stock. The ADAM and EVE lines count and assess viability of cells in suspension, a routine step that precedes seeding, passaging and most downstream assays in cell culture work. These are compact instruments, which is part of why so many of them circulate second-hand: a lab upgrading or closing a project releases a working counter that another lab can absorb without retraining staff. Across the 113 NanoEnTek items listed, this class is well represented, and the used examples sit at the lower end of the price band. That matters for a group standardising on a single counting method across several benches, where buying three used units costs less than one new multi-channel system from a larger maker.

The second pattern is the breadth of instrument classes under one name. A lab sourcing from NanoEnTek can find a cell counter, a live-cell imaging system from the JuLI series and a fluorescence immunoassay analyser without moving to a different manufacturer. The JuLI instruments sit inside an incubator and record growth, migration and confluence over time, which suits proliferation and wound-healing studies where manual imaging would interrupt the run. The FREND analyser works on a different principle, reading fluorescence from a disposable cartridge for quantitative immunoassay at the point of care. The three do not compete with each other, so a single supplier relationship can cover counting, imaging and assay readout. On the marketplace, 9 verified suppliers and distributors carry this range, which gives a buyer more than one source to compare on condition and delivery.

The third pattern is condition mix, and it is where the catalogue is most useful for budgeting. 29 percent of the listings are used. The remainder are new, so a buyer is not forced into one condition or the other and can decide per instrument. A core counter that runs daily might be worth buying new for the longer service life, while a second unit for an occasional protocol is a clear case for used stock. Prices run from EUR 215 to EUR 4.819. The spread reflects the difference between a consumable-heavy counter and a complete imaging system, so the average of EUR 1.617 says little about any single listing; read each one on its own specification.

Where NanoEnTek is harder to assess is long-term parts and consumable supply, since several of these instruments depend on disposable chips and cartridges. On Questpair those parts can be sourced through the marketplace, and warranty on a used unit is arranged in consultation for the specific listing rather than set across the board. A buyer should treat each listing as its own transaction and confirm what is included before committing.

**Cell counting instruments at a fraction of new pricing**

Automated cell counters from the ADAM and EVE lines make up a large part of the 113 NanoEnTek items on Questpair, with used units listed below their new equivalents.

**One manufacturer across counting, imaging and diagnostics**

NanoEnTek equipment on the marketplace spans automated cell counters, live-cell imaging systems and fluorescence immunoassay analysers, so a lab can source several instrument classes from a single maker through 9 verified suppliers and distributors.

**Both new and used stock available side by side**

Of the listed NanoEnTek instruments, 29 percent of the listings are used, giving buyers a choice between new units and lower-priced second-hand stock within the same catalogue.
