ISO13485 Certified YSTE504B Digital Coagulation Analyzer for Clinical Labs

You load your plasma samples into the 16-position rotor, load reagents into the 6 positions on the heated block, and you're basically ready to run PT, APTT, TT, and FIB on up to four channels simultaneously — the instrument handles the incubation and mixing sequence automatically after you hit start.

It maintains 37°C within ±0.5°C across all channels, which is tighter than many bench-top units we've seen, and the CV stays at or below 3% — we've verified this across roughly 200 test runs during validation, and it holds consistently even when ambient lab temp fluctuates.

A complete four-parameter run takes ≤300 seconds form sample loading to printed result, so you can push through a 30-patient batch in about 40 minutes or so without feeling rushed. The 7-inch color touchscreen shows clotting curves in real time, and we've found that most techs prefer the graphical trace over just a numeric readout.

For data management, it stores 100 parameter sets and 1000 results internally — plenty for a mid-size lab running a couple hundred tests per week — and the RS232 port lets you dump to an LIS if needed. The 58mm thermal printer is built in, so you don't need external peripherals unless you want a dedicated network connection.

One thing we don't recommend: this analyzer isn't suited for high-throughput core labs doing 500+ tests daily on a single shift — the 16-sample rotor and 6-reagent positions mean you'll be reloading frequently, and there's no continuous-load mechanism. It's really a fit for stat lab, the outpatient clinic, or the small hospital coagulation bench where workflow is batch-oriented.

We typically stock these with a 5-day lead time, and teh MOQ is one unit — we'll include the thermal paper roll and a starter pack of cuvettes. The power supply runs on 220V ±15% at 50Hz, pulling about 80VA, so check your local voltge before ordering.
