Floor-Standing Fully Automatic Chemistry Analyzer

What is the Floor-Standing Fully Automatic Chemistry Analyzer?

A floor-standing chemistry analyzer uses a larger reaction rotor, bigger reagent storage and a high-throughput sample handler to deliver 800 to 2000 tests per hour. It suits large hospital core laboratories and reference laboratories with continuous test demand.

Overview

The larger platform is built around a reaction rotor holding 120 to 300 cuvettes and reagent compartments with 60 to 90 refrigerated positions, so a shift or a full day can run without reagent changes. Sample loading uses racks or a track connection with continuous access, and one or two probes handle aspiration with clot and liquid-level detection. Photometric reading occurs at multiple wavelengths during rotation, and absorbance is recorded as often as every few seconds to support kinetic assays. Because the instrument runs continuously, water consumption and waste volume are higher, and a dedicated water purification system and drain are usually required. Reliability features include automatic rerun and dilution, reagent and cuvette inventory management, and remote diagnostics, and many models can be connected to an automation track later.

How does it work?

A fully automatic analyzer moves tubes from a sample tray or rack to an aspiration station, where a probe with liquid-level and clot detection withdraws a measured volume. Reagent probes add the programmed volumes from refrigerated reagent positions, and the mixture is delivered into a reaction cuvette on a thermostatted rotor held at 37 degrees Celsius. A photometer with interference filters or a diffraction grating reads absorbance at several wavelengths, and the software applies the programmed calculation mode, converts the signal into concentration using the calibration curve and flags results that fall outside the linear range. Automatic dilution and rerun, carryover-free cuvette washing, onboard quality control with Levey-Jennings charts, and reagent inventory tracking are standard. Sample and reagent barcodes, patient demographics and test orders pass between the analyzer and the laboratory information system through HL7 or ASTM interfaces.

What are the key features?

• Reaction rotor with 120 to 300 cuvette positions
• 60 to 90 refrigerated reagent positions for shift-long operation
• Throughput of 800 to 2000 photometric tests per hour
• Continuous rack or track sample loading with clot detection
• Kinetic readings every few seconds for enzyme assays
• Remote diagnostics and optional track connection

What are the technical specifications?

A typical floor-standing fully automatic chemistry analyzer configuration offers throughput of 800–2000 tests/h photometric, reaction cuvettes of 160 positions, reusable with automatic washing, reagent positions of 70 refrigerated positions at 4–10 °C, sample handling of Rack loader with 100 tubes, continuous access, minimum sample volume of 1.5 µL per test and reading interval of Down to 4 s for kinetic assays. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Floor-Standing Fully Automatic Chemistry Analyzer is used in large hospital core laboratory testing, reference laboratory high-volume panels, continuous inpatient and outpatient chemistry and consolidated multi-site testing. Across the wider Fully Automatic Analyzers class, laboratories also deploy it for hospital routine and emergency chemistry, metabolic, liver, kidney and lipid panels and specific protein measurement by immunoturbidimetry.

Which standards and certifications apply?

Relevant standards and methods include ISO 15189, CLSI EP05, CLSI EP06, CLSI EP07, CLSI C24, IEC 61010-1 and IEC 61010-2-101. Certification candidates for this model are CE, ISO 13485 manufacturing and NMPA class II registration; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

The analyzer needs a stable, level floor or bench with adequate load capacity, a dedicated grounded power supply, controlled temperature and humidity, and purified water of consistent quality. Verify performance at installation with precision, linearity, carryover and method comparison studies following CLSI protocols, and validate the reference intervals against the local population. Daily tasks include checking water quality, reagents and waste, running two or three levels of control and reviewing the calibration status. Weekly and monthly maintenance covers probe cleaning, cuvette washing efficiency and photometer checks, and lamps, tubing and syringes are replaced on schedule. Instruments that handle patient samples must be decontaminated according to the manufacturer procedure before service, and all waste is treated as infectious.

How do I select the right Floor-Standing Fully Automatic Chemistry Analyzer?

Choose a floor-standing analyzer when more than about eight hundred tests are run per day, when reagent changes during the shift interrupt work, or when connection to an automation track is planned. In the RFQ confirm the effective throughput on your menu, water and drain requirements, floor loading, and the redundancy plan if the analyzer stops, since a single floor-standing instrument is a significant single point of failure.

How does it compare with other Fully Automatic Analyzers variants?

Size the analyzer by daily and peak-hour test volume, then add thirty percent headroom for repeats and quality control. Determine whether you need open reagent channels for cost control or a closed system for convenience. Check the reaction cuvette type, because reusable cuvettes lower consumable cost but require a wash station, while disposable cuvettes simplify maintenance. Confirm the sample volume, which matters for pediatric work, and the reagent capacity per shift. Decide which integrated modules you need, such as ion-selective electrodes for sodium and potassium or immunoturbidimetry for specific proteins. Verify STAT access, first-result time, onboard water consumption and waste handling, LIS interface protocols, and the local availability of service, spare parts and application support before ordering.
