Sensor solutions for laboratory automation


There are three things that are expected of sensor solutions in laboratory automation: reliability, safety and user-friendliness.

It is not without reason that the safety requirements for in-vitro diagnostics are especially high: this lab work involves human samples. Extremely strict specifications apply here and there is no tolerance for error. This also places high demands on the used camera-based 1D- and 2D-code readers of the DCR 50 and DCR 200i series, for example. With their sophisticated design and special optics they combine the factors of speed, reliability, safety and a user-friendliness that helps to pre-emptively minimize the risk of errors.

Areas of application and product highlights

Pre-Analytic Instruments

Sensor solutions for pre-analytic instruments

To ensure the sample integrity as well as for hygiene and safety reasons, automatic sample distributors are used increasingly in the preparation of the analyses. These ensure reliable and fast preparation and assignment of the chaotically delivered samples independent of the number of samples and, above all, avoid cross contamination. Thanks to high function reserves, our sensor solutions guarantee maximum system availability during analysis preparation. High-performance bar code readers, for example, are used to identify the information on the sample tubes and prepare it for the automatic analyzers. Or, we use optical sensors within the machines to ensure that the seals were properly removed and that the samples are reliably prepared for the next steps.

  2. 1D-code identification / BCL 8
  3. Monitoring the closing state of the flap / MC 3x / RD 800
  4. Cap detection / 2/3 series
  5. Identification of samples / CR 50/55

IVD Analyzers

Sensor solutions for IVD analyzers

Modern analysis procedures for examining body fluids or tissue are now highly automated, thereby allowing processes to be performed very efficiently and safely. Zero tolerance is essential here both during the handling as well as during the assignment of samples to the patient. The sensors that are used must, therefore, reliably master high throughputs and be extremely compact so as to minimize space requirements in the systems. Our bar code readers for tubes, for example, can have a reading field height of 80 mm to be able to reliably detect at just a short distance. Depending on where the automatic machine is used and the volume of sample that is to be analyzed, carousel, single- or multi-lane, or point-of-care solutions are used. Maximum reliability is the most important property of our sensor solutions for laboratory analysis. Our high-performance code readers for 1D- or 2D-codes DCR 50 and DCR 80 serve as, e.g., elementary function units for these automatic machines, as they must detect the samples with absolute certainty to allow the analysis results to be assigned error-free. Capacitive sensors are used in automatic analyzers as an early warning system to safeguard the processes and reliably report the unplanned release of sample liquids. Our CSL light curtain safeguards the interior of the analyzers, thereby preventing, e.g., tampering with samples.

Automation Modules

Sensor solutions for automation modules

For complex analyses, samples need to be transported between various machines. This networking of the analyzers is increasingly being performed with compact, mini conveying belts and handling robots. The individual parts must be moved quickly, safely and reliably here and, prior to the subsequent analysis steps, also be detected and assigned without error. Furthermore, gapless traceability of the sampling path must be ensured. Sensors make sample transport more reliable and minimize the risk of standstills in the analyzers which could, among other things, jeopardize the sample integrity. Our compact, camera-based DCR 200i code reader enables, e.g., the fast detection of 1D- or 2D-codes even while in motion, guaranteeing fast sample transport. Along the transport route, safety proximity sensors such as the MC 300 or RD 800 monitor the closing state of the protection hoods and highly visible signal lamps indicate the process state.

  2. 1D- and 2D-code identification / DCR 200i
  3. Monitoring the closing state of the protection hood / MC 3x / RD 800

Post-Analytic Instruments

Sensor solutions for post-analytic instruments

Particularly when storing samples, dependable closure is extremely important for eliminating the possibility of subsequent contamination. In some cases, the storage is performed in deep-freeze conditions at temperatures at – 80°C, at which the sensor technology must continue to detect reliably. In addition, sensors ensure the traceability of the samples all the way to their storage location. Even after the actual analysis, sensors continue to make the processes faster and more reliable. Sensors with high resolution, flexible fiber optics are used to check, e.g., the proper affixing of sealing films, ensuring that processes are completed professionally. During sample storage, sensors such as the 2 series monitor for presence, even at extremely low temperatures.

  2. Presence control / 2/3 series
  3. 1D- and 2D-code identification / DCR 200i
