A variety of pumps are required in diagnostic applications such as clinical chemistry, hemostasis analysis, immunology and microbiology to move or transfer small volumes of samples or reagents, dispense bodily fluids, clean needles, and remove residues. Whatever pump type is needed for In Vitro Diagnostics, TriContinent Scientific and Thomas offer all solutions you need.
TriContinent Positive Displacement and Air Displacement Syringe Pumps are critical components for high precision liquid handling in laboratory instrumentation. Most common functions performed by pumps in in vitro diagnostic workflows are sample preparation tasks, reagent dosing, cleaning processes and removal of analysis liquid. TriContinent Scientific team of experts can provide multiple solutions that meet the requirement of your IVD instrument; whether it is high-precision dosing or avoiding cross-contamination.
When selecting a syringe pump for your instrument you have the choice between air displacement and positive displacement technology. Both solutions serve the function to move liquids in your workflow with very high precision and accuracy but, depending on the application, one technology can be more beneficial than the other.
Comparing the functions and benefits of Air Displacement vs. Positive Displacement technology:
Clinical chemistry analyzer*
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 analyzer* (COVID-19, HIV, etc.)
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 analyzer* (bacterial infections, e.g. E.coli)
Microbiology is a branch of science which deals with the study of micro-organisms including bacteria, viruses, fungi, protozoa and parasites.
