Fully Automated Coagulation Analyzer with Cap-Piercing Autoloader

What is the Fully Automated Coagulation Analyzer with Cap-Piercing Autoloader?

This analyzer aspirates directly from closed citrated tubes using a cap-piercing probe and a rack autoloader, reducing aerosol exposure and eliminating manual uncapping. It suits hospital laboratories that handle large numbers of tubes and prioritise operator safety.

Overview

Tubes are loaded into racks and identified by barcode, and the piercing probe penetrates the stopper once, aspirates plasma through a level-sensing needle and withdraws before the tube continues to its next destination. Because the tube is never opened, the operator does not contact plasma directly, which reduces biohazard exposure and preserves sample integrity for retesting. Dead volume is slightly larger than in open-tube sampling, which matters for pediatric and short-draw tubes, and the instrument usually requires a minimum fill level to be programmed. Racks accommodate standard 13 and 16 millimetre tubes with heights between 75 and 100 millimetres, and continuous loading allows urgent tubes to be inserted during a run. Rack handling, barcode reading and probe washing are fully automatic, and the software links results to test orders through the LIS interface.

How does it work?

An automatic analyzer moves plasma from a sample tube to a reaction cuvette, adds reagent from a cooled position, incubates at 37 degrees Celsius and starts the measurement. Detection may be optical, using the change in light scatter or turbidity as fibrin forms; mechanical or magnetic, following the movement of a ball; or chromogenic, measuring the colour released from a synthetic substrate at 405 nanometers. Immunoturbidimetric channels measure light scattered by antigen-antibody complexes for assays such as D-dimer. The software applies the stored calibration for each reagent lot, calculates ratios and international normalised ratios, applies reflex rules such as automatic repeat at a dilution, and flags results for review. Random access allows any test combination on any sample, and STAT samples are given priority so that emergency results are not delayed by routine batches.

What are the key features?

• Cap-piercing probe aspirating directly from closed tubes
• Rack autoloader with continuous loading and barcode identification
• Reduced aerosol and direct plasma exposure for operators
• Sample integrity preserved for repeat testing
• Programmable minimum fill level for short-draw tubes
• Automatic rack handling and probe washing between samples

What are the technical specifications?

A typical fully automated coagulation analyzer with cap-piercing autoloader configuration offers sampling mode of Closed-tube cap piercing, throughput of 200–400 clotting tests/h, autoloader capacity of 10 racks of 10 tubes with continuous loading, tube compatibility of 13 and 16 mm diameter, 75–100 mm height, dead volume of About 150–200 µL plasma and minimum fill level of Programmable with warning for short draws. 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 Fully Automated Coagulation Analyzer with Cap-Piercing Autoloader is used in high-volume hospital hemostasis testing, biosafety-focused laboratory workflows, multi-ward sample batch processing and laboratories consolidating phlebotomy tube handling. Across the wider Automatic Coagulation Analyzers class, laboratories also deploy it for hospital routine and emergency hemostasis testing, anticoagulation monitoring and dosing and pre-operative and bleeding disorder assessment.

Which standards and certifications apply?

Relevant standards and methods include ISO 15189, CLSI H57, CLSI H21, CLSI EP05, CLSI EP15, 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.

Install the analyzer on a stable bench or floor position with controlled temperature, a grounded power supply and space for reagent and waste containers, and verify performance at installation with precision, linearity and method comparison studies for every assay reported. Daily work includes running normal and abnormal control plasma, checking reagent and cuvette status and reviewing calibration validity. Optical and mechanical detection systems need periodic cleaning and mechanical alignment checks, and the sample and reagent probes require regular decontamination. Because pre-analytical variables strongly influence coagulation results, the laboratory should monitor tube fill, transport time and centrifugation parameters as part of quality management, and participate in external quality assessment for all reported assays.

How do I select the right Fully Automated Coagulation Analyzer with Cap-Piercing Autoloader?

Specify cap piercing when operator safety and workflow efficiency are priorities and most tubes are standard-sized. In the RFQ state the tube dimensions and fill volumes used locally, the acceptable dead volume for pediatric samples, the barcode symbologies, and the required behaviour when a tube is flagged for repeat testing.

How does it compare with other Automatic Coagulation Analyzers variants?

Match the instrument to your workload and menu. A benchtop analyzer with two to six reagent positions suits a laboratory reporting one hundred to three hundred tests per day, while high-throughput models with multiple reagent carousels are needed above about five hundred tests. Check which detection principles are available, because chromogenic and immunoturbidimetric assays require additional channels and reagents, and check whether cap piercing is needed for biosafety. Consider the sample volume for pediatric tubes, reagent onboard capacity and refrigeration, STAT handling and first-result time, reflex rules such as automatic dilution, and the availability of application support and calibrators. Confirm LIS connectivity and the traceability features, including lot, curve and operator records required for accreditation.
