HUMAN Diagnostics / HUMAN Laboratory Analyzers

Architectural highlights and photometric capability of HumaStar 200 and 300SR analyzers

Automated random-access clinical chemistry analyzers HumaStar 200 and HumaStar 300SR are engineered by German manufacturer HUMAN to support small, medium and urgent stat laboratories.

The HumaStar 200 provides an analytical speed up to 200 photometric tests per hour with a sample carousel accommodating 60 primary collection tubes and 30 cooled onboard reagent containers.

Integrated 2D barcode scanners automate data entry for calibrator values, reagent lots and test parameter protocols.

The HumaStar 300SR platform scales throughput to 300 tests per hour while providing 40 refrigerated reagent bays. A primary engineering achievement is its fluidic system operating with deionized water consumption below three liters per hour.

The instrument incorporates ultrasonic clot detection probes, multi-stage reaction cuvette wash stations with optical purity verification and bi-directional laboratory information system connectivity for seamless digital reporting.

High-throughput round-the-clock operation of HumaStar 600 with direct ISE module

The flagship HumaStar 600 analytical workstation is constructed for continuous 24/7 workload demands in central hospital laboratories and regional diagnostic networks.

Operating at a standard photometric rate of 600 tests per hour, throughput expands to 780 tests per hour upon integrating the optional direct ion-selective electrode module. The ISE module performs simultaneous potentiometric determination of sodium, potassium, chloride and lithium ions.

A large specimen rotor accommodates 95 positions for routine tubes, stat samples, calibrators and control sera. The cooled reagent department houses 48 bottles, maintaining onboard solution stability throughout multi-day shifts.

Liquid handling arms feature capacitive liquid level sensing, vertical crash protection and micro-metering precision, keeping measurement variation coefficients below one percent across high-volume test batches.

Flow cytometry and impedance detection in HumaCount hematology and CRP analyzers

The HumaCount instrument family combines cell counting methods to profile whole blood cellular elements. For routine three-part differential screening, HumaCount 30TS and 80TS systems rely on proven electrical impedance sensing across precision micro-apertures.

Built with vivid color touchscreens and internal thermal printers, they offer straightforward maintenance and automated cleaning flushes.

The multi-parameter HumaCount 5D CRP integrates semiconductor laser optical flow cytometry with latex immunoturbidimetry within a benchtop chassis.

It delivers a comprehensive 5-part white blood cell differential while simultaneously measuring C-reactive protein concentrations from a single blood tube. This eliminates separate plasma centrifugation steps and expedites clinical triage in critical inflammatory scenarios.

Optical design and temperature regulation in HumaLyzer semi-automated photometers

Semi-automated clinical photometers in the HumaLyzer lineup, including the HumaLyzer 4000 and the compact HumaLyzer Primus NG, perform enzymatic, colorimetric and turbidimetric clinical chemistry methods.

The optical pathway centers on durable quartz flow cells enclosed within a temperature-controlled thermal block holding measurement reactions steadily at 37 degrees Celsius with tenth-of-a-degree stability.

The HumaLyzer 4000 optical wheel houses eight interference filters spanning 340 to 670 nanometers, covering routine and specialized clinical chemistries.

Equipped with internal incubation wells for sample pre-warming, a membrane keypad, graphic display and onboard memory for hundreds of protocols, the photometer stores non-linear multi-point calibrations and Levey-Jennings quality control graphs.

HumaClot hemostasis analyzers and automated ESR monitoring with HumaSRate systems

Hemostasis testing within the HUMAN diagnostic range centers on HumaClot Junior and Duo Plus coagulometers, evaluating fibrin clot formation kinetics in citrated plasma samples. Measuring channels incorporate optical shielding and 37-degree heating elements.

Optical-mechanical detection with magnetic stir-bar agitation yields precise clotting times even when evaluating turbid, icteric or lipemic patient specimens.

To monitor systemic inflammation, the automated HumaSRate 24PT analyzer measures erythrocyte sedimentation rates conforming to the Westergren method. It scans optical fluid boundaries directly inside primary vacuum collection tubes without uncapping or liquid pipetting.

This protects technicians from biohazard exposure and prevents contamination of infectious whole blood specimens.

Preventive maintenance intervals, fluidic sanitation and factory replacement parts

Long-term analytical accuracy of HUMAN diagnostic instruments requires routine preventive maintenance and timely replacement of wear-prone items.

Fluidic circuits in HumaStar chemistry systems and HumaCount counters demand periodic renewal of peristaltic pump tubing, syringe Teflon plunger tips, check valves and deionized water filters. Residual protein build-up is systematically eliminated using enzymatic wash reagents.

Optical detection blocks in photometers and coagulometers undergo regular lamp intensity checks, condenser lens cleaning and baseline drift verification with distilled water.

When procuring replacement pumps, valves, sensors and sampling needles, selection follows the instrument nameplate serial data. Utilizing matched system reagents and AUTOCAL materials guarantees full analytical traceability.
