Refurbished Beckman Coulter AU680 with ISE Chemistry Analyzer
The AU680 with ISE is a variant of the Beckman Coulter AU680, Beckman reference A91925, built with an indirect ISE module for sodium, potassium and chloride. The 150-sample rack loader, cooled STAT compartment, 108 reagent positions, triple-reagent capability and whole-blood HbA1c are the same as on the base AU680.
What the ISE module means for a hospital core lab
trending_up1,200 tests an hour instead of 800. The ISE runs alongside the photometer, adding up to 400 electrolyte tests an hour without touching photometric capacity. On a heavy morning, electrolytes from the ED and inpatient floors don't queue behind your liver panels and lipids.
science63 assays on board instead of 60. Sodium, potassium and chloride sit on the ISE, so all 60 photometric positions stay free, and you're less likely to swap reagents on and off between shifts.
join_innerOne analyzer for the whole metabolic panel. BMPs and CMPs finish on the AU680 from one tube, so you avoid the aliquots, the second instrument and the result merging.
buildLong-life electrodes. Beckman built the AU680's ISEs for long onboard life, so electrode changes come around less often. You'll still need ISE buffer, other ISE reagents and routine ISE maintenance.
conveyor_beltOne less instrument on automation. If the AU680 sits on a Beckman track, keeping electrolytes on it means one less analyzer for the line to route tubes to.
Which AU680 fits your lab
boltChoose the AU680 with ISE if your chemistry analyzer is where electrolytes should run, or you're retiring a stand-alone electrolyte analyzer.
check_circleChoose the AU680 (Beckman reference A91921) if your blood gas analyzers already cover electrolytes.
upgradeChoose the DxC 700 AU with ISE if you want the same 1,200-test ceiling on Beckman's newer platform, with reagent loading mid-run.
A refurbished AU680 with ISE from Diamond costs up to 70% less than new. Our engineers install it, verify your assays and electrolytes, and service it afterward, ISE included. Financing starts at $0 down, and we take trade-ins.
