Modular Pre-Analytical Automation System

What is the Modular Pre-Analytical Automation System?

A modular pre-analytical automation system automates sorting, centrifugation, decapping, aliquoting and labeling without connecting to analyzers by track. It suits mid-sized laboratories that want to cut manual preparation steps first and keep analyzers as stand-alone instruments.

Overview

Pre-analytical automation covers the most labor-intensive steps that precede analysis. Tubes are loaded in racks or bulk, identified by barcode, sorted into racks for each destination, centrifuged, decapped and, where needed, aliquoted into labeled secondary tubes. Modules can be purchased separately and combined, so a laboratory can start with a sorter and add a centrifuge and decapper later. Output racks are taken manually to analyzers, which keeps integration simpler and investment lower than a full track. Typical throughput is 300 to 600 tubes per hour. Liquid-level detection and cap-type recognition reduce errors, and middleware can connect to the LIS to fetch orders. The footprint is typically 6 to 15 square meters.

How does it work?

A laboratory automation system links modules through a transport layer, usually a conveyor track carrying individual tube carriers, or robotic arms and carts for smaller installations. Each carrier holds a tube that is identified by a barcode or RFID tag at input. Control software, often called middleware, queries the laboratory information system for the test orders, decides which instruments and modules the tube must visit, and routes it through decapping, centrifugation, aliquoting, analysis, resealing and storage. Sensors and cameras check tube type, cap, fill level and serum quality. Grippers handle tube formats of various diameters and lengths. Tracking data are logged, so each tube's location and status are always known, and urgent samples can be prioritized in the queue.

What are the key features?

• Stand-alone sorting, centrifuge, decapping and aliquoting modules that can be combined
• Barcode reading with LIS order query at the input station
• Cap-type and tube-type recognition to avoid handling errors
• Liquid-level detection for aliquoting into labeled secondary tubes
• Output racks sorted by destination analyzer or department
• Footprint suited to existing laboratories without track installation

What are the technical specifications?

A typical modular pre-analytical automation system configuration offers throughput of 300–600 tubes/h, tube diameter of Ø 12–16 mm, tube length of 75–100 mm, input capacity of 50–200 tubes, output sorting lanes of 10–40 racks and decapping rate of Up to 500 tubes/h. 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 Modular Pre-Analytical Automation System is used in mid-sized hospital laboratory, commercial clinical laboratory, phased automation projects and blood center processing. Across the wider Laboratory Automation class, laboratories also deploy it for high-volume hospital laboratory workflows, reference laboratory specimen consolidation and emergency department STAT testing.

Which standards and certifications apply?

Relevant standards and methods include CLSI AUTO01, CLSI AUTO03, CLSI AUTO04, CLSI AUTO05, ISO 15189, IEC 61010-1, IEC 61010-2-101 and CLSI GP44. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Automation needs a level floor with adequate load rating, stable power with UPS backup, network connectivity and, where pneumatic modules are used, compressed air. Plan the layout for operator access and service clearance. Validate the installation through functional testing, carryover and sample identification checks, and verify interfaces with the LIS and each analyzer. Establish downtime procedures so that testing can continue manually if the track stops. Schedule preventive maintenance for belts, grippers and sensors, and clean carriers regularly. Follow biosafety practice for decapped tubes and aerosol control, and document validation under ISO 15189. Train staff on error recovery and on loading rules for tube types.

How do I select the right Modular Pre-Analytical Automation System?

Choose a modular pre-analytical system when volumes are 300 to 1,000 tubes per day and analyzers cannot be connected to a track. In the RFQ, state daily tubes, tube and cap types, the required modules, sorting destinations, LIS protocol and available space, and ask whether a track can be added later.

How does it compare with other Laboratory Automation variants?

Selection starts with daily tube volume, number of analyzers to connect and available floor plan. Small laboratories below a few hundred tubes per day may need only a pre-analytical module, while laboratories handling over 1,000 tubes benefit from a full track. Verify which analyzers the track can connect to, because open interfaces and third-party instrument support vary. Check tube formats and sizes, cap types, centrifuge capacity, urgent-sample handling, output buffer size and storage capacity. Confirm middleware functions such as rules-based routing, autoverification and reflex testing, and LIS interface protocols. Consider uptime, service response, spare parts, training, and the power, network and air requirements of the installation site.
