Automated Screening System

What is the Automated Screening System?

An automated screening system runs large numbers of assay plates through addition, incubation and detection to test many samples or compounds. It is central to modern drug discovery and high-throughput screening laboratories.

Overview

An automated screening system processes assay-ready plates in high volume. It typically combines a plate hotel, a liquid handler for compound or reagent addition, an incubator, a plate reader for absorbance, fluorescence or luminescence, and sometimes a washer, all under one scheduler. Assays may be endpoint or kinetic, and the system records plate and well data with timestamps so that kinetics can be analyzed. Compound or sample libraries are stored and retrieved by barcode, allowing cherry-picking and dose-response series. The scale ranges from a compact bench-top line to a large integrated screening platform handling thousands of plates per day. Assay quality is monitored with controls and statistical measures such as the Z-prime factor, and the system flags plates that fail acceptance criteria for review.

How does it work?

Biotech automation systems replace manual handling with mechanical motion controlled by software. A liquid handler aspirates and dispenses precise volumes with air-displacement or positive-displacement pipettes, using disposable tips or fixed probes washed between steps. Robotic arms or grippers move microplates, tube racks and labware between modules, while sensors and teach points define positions. Scheduling software, sometimes called a scheduler or method editor, coordinates the modules, resolves resource conflicts and tracks each plate and sample. Detection modules add readers, imagers or thermal cyclers so that assays run without manual transfer. Air-displacement pipetting, tip-touch, liquid-level detection and calibrated pumps determine accuracy and precision, while deck design, labware definitions and error recovery determine reliability during long unattended runs.

What are the key features?

• Integrated addition, incubation and detection
• Endpoint and kinetic assay support
• Compound and sample library management
• Plate and well data with timestamps
• Assay quality monitoring with controls

What are the technical specifications?

A typical automated screening system configuration offers throughput of Up to 1,000–5,000 plates per day, detection modes of Absorbance, fluorescence, luminescence, plate formats of 96, 384, 1536-well, incubation of Ambient to 45 °C with CO2 option, compound storage of Plate or tube libraries, barcoded and kinetic reads of Multiple reads with timestamps. 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 Automated Screening System is used in drug discovery high-throughput screening, compound library screening, genomics and functional assays and agricultural and chemical screening. Across the wider Biotech Automation class, laboratories also deploy it for high-throughput screening, genomics and molecular biology workflows and cell line development and clone screening.

Which standards and certifications apply?

Relevant standards and methods include ISO 9001, ISO 13485, 21 CFR Part 11, EU GMP Annex 11, ISO 15189, IEC 61010-1 and ANSI/SLAS microplate standards. Certification candidates for this model are CE, ISO 9001 manufacturing and 21 CFR Part 11 software documentation; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Qualify the system against your methods with accuracy and precision studies at the volumes used, and repeat them after major service. Keep labware definitions current, because a changed plate height or well geometry causes collisions or poor pipetting. Train operators in method editing, teach-point adjustment and error recovery, and restrict who can change methods. Monitor tip and consumable supply, and clean probes, grippers and optics on schedule. For regulated workflows, control software and method versions, review audit trails and confirm that barcodes and results transfer correctly to the laboratory information system. Confirm that the installation meets the manufacturer's requirements for bench stability, power and, where relevant, ventilation and IEC 61010-1.

How do I select the right Automated Screening System?

Choose a screening system from the assay chemistry, plate format and daily plate volume. In an RFQ specify detection modes, plate formats, incubation conditions, library storage, kinetic read capability, scheduling, data output and the QC measures supported.

How does it compare with other Biotech Automation variants?

Begin with the workflow you want to automate and the number of samples per day. Choose pipetting channels and volume range from the assay, and confirm accuracy and precision at the low volumes you actually use. For plate movement, define the number of plates in play and the storage and incubation needs, and decide whether a standalone liquid handler, a plate robot or a full workcell is required. For screening, confirm detection compatibility and the ability to run kinetic assays. For colony picking, check the target size, sterility and picking throughput. Across the category, evaluate deck capacity, labware support, scheduling flexibility, integration with readers and incubators, error handling, barcode tracking and the software traceability and validation you need.
