A variety of pumps are required in clinical chemistry, hemostasis analysis, immunology and microbiology to dose reagents, dispense bodily fluids, clean needles, and remove residues. Whatever pump type is needed for in-vitro diagnostics, there is only one global supplier that meets them all - Thomas.

Place of Liquid Pumps in the In Vitro Diagnostics Workflow

Liquid Handling Workflow in IVD Diagnostics

Thomas Liquid Diaphragm and Liquid Peristaltic Pumps are a critical component of various analyzers that are used for IVD tests. Most common functions performed by pumps in IVD workflow are cleaning processes, reagent dosing, and removal of analysis liquid.

In Vitro Diagnostics Functions

  • Collection, preparation, and examination of biological specimens
  • Screening
  • Diagnosis
  • Curing, treating, and preventing diseases
  • Detection (candidates who may benefit from certain therapies, genomic variations, etc.)
  • Treatment monitoring processes


Diagnoses Capable With In Vitro Diagnostics


When specifying pump flow for oxygen concentrators and ventilators, the rule of thumb is that pump flow should equal five times the requirement for the device.

  • Infections (e.g. meningitis, pneumonia, kidney infection, COVID-19 PCR and antibody tests)
  • Diseases (e.g. HIV, TB, malaria, HBV/HCV, Cystic fibrosis, or Huntington’s)
  • Cancer
  • Cardiac (e.g. cardiovascular disease, myocardial infarction, heart failure, atrial fibrillation)
  • Immune System (e.g. COVID-19 antibody tests)
  • Nephrology
  • Gastrointestinal


Selecting the Right Pump for Your Application


Our highly integrated small pumps are characterized by robust performance and are the first choice for OEM Diagnostic equipment device manufacturers. Depending on your equipment and function performed by the pump there are three major technologies to consider, taking under consideration the performance and application requirements.

Thomas is famous for a value added engineering and customization. Thus, we can modify our pumps and compressors to meet your specific requirements or tailor them to your IVD equipment.


Thomas Pumps for IVD Applications

Types of IVD Devices and Applications that uses Thomas Liquid Pumps



Serum / plasma is separated from the blood and then analyzed for presence of different substances.


Hemostasis is the body’s reaction to bleeding. There are three methods of defining the coagulation process: measuring the clotting time, analyzing the blood components or counting the number of blood cells.


Immunology is concerned with how the body reacts against foreign bodies. This can range from finding out if somebody has an allergy to diagnosing AIDS.


Microbiology is a branch of science which deals with the study of micro-organisms including bacteria, viruses, fungi, protozoa and parasites.
