In-Vitro Diagnostics (IVD) Pumps
Diener Precision Pumps are the ideal choice for fluid management within In-vitro diagnostics (IVD) systems. Our precision gear pumps are typically used for bulk fluid transfer and waste fluid removal, whereas our metering/dosing pumps are used to move and dose reagents, buffers, and solvents.
IVD Fluid Transfer Gear Pumps
DPP gear pumps are typically used for bulk transfer and waste fluid removal, and are preferred for the following reasons:
- Constructed from chemically inert materials: typically stainless steel, PEEK, and EPDM
- The pump head is magnetically coupled without seals, eliminating any risk of leakage
- The low inertia of the Diener design results in faster response times and lower power consumption
- The pumps are self-priming
- The unique flow-through design allows for faster clean-in-place
- Properly applied, the pumps will last the life of the instrument
Compact and Adjustable Reagent Metering Pumps
- Metering pumps are typically used for agents, buffers, and solvents
- Inert materials of construction: alumina ceramic and ETFE
- The pump displacement is adjustable in the range of zero to 500 microliters per stroke
- The pumps are fitted with an optical sensor that defines the “home” position
- Smooth and quiet operation throughout the speed range thanks to the balanced driving elbow
- Quick installation time and space-saving with their multiple ports and mounting options
- Double-ended metering pumps allow pre-configured dosing where precise mixing ratios are required. Each end can be independently adjusted

in the In-Vitro Diagnostics Workflow
Case Study – Ratio Metering Challenge
The customer wanted to accurately mix a concentrated base solution with water. The volumetric ratio had to be within 0.5 µL per stroke. Using two pumps was expensive and presented electronic control challenges.
Diener’s adjustable metering pumps can be calibrated at precise dispense volumes, so it made sense to mount one pump to each end of a stepper motor. The pumps operate together and are calibrated to the exact volumetric ratio, in this case 1 part buffer to 10 parts water. By using different piston diameters, we were able to fulfill other mixing ratios up to 100:1 using the same basic pump design.
Why DPP pumps are the preferred choice for laboratory and medical diagnostic technology
Chemically Resistant Pumps
Our pumps are made from materials that are resistant to a wide range of aggressive chemicals. This means our pumps can also operate reliably and precisely in the harshest laboratory environments.
DPP IVD gear and metering pumps are all characterized by their robustness and performance. Wear and tear is at its lowest, and their smart designs ensure a sustainable reduction of operating costs.
Low Noise Pumps
Thanks to intelligent design, our pumps are some of the quietest of their kind. This makes them unbeatable when it‘s important to have peace and quiet.
Pumps tailored for your IVD system
All DPP pump solutions are tailored to your in-vitro diagnostics (IVD) system requirements and are 100% tested and calibrated before they leave the factory. Our world-renowned Swiss quality ensures long-life reliability and enhances your instrument competitiveness.
