Cleaning dosing needles quickly and reliably

When testing blood, serum and urine, reliability is the top priority. How can you clean dosing needles quickly and residue-free? Discover why a Bürkert system solution makes your in-vitro analysis device more efficient!

Your advantages

  • Cleaning dosing needles quickly and reliably
  • Efficient use of reagents and cleaning liquids
  • Long service life thanks to chemically resistant materials
  • Compact design with minimum dead space
  • High level of tightness and high flow coefficient

Correct results are only guaranteed with clean dosing needles

Be it in the field of haematology, clinical chemistry or immunology: Reliability and accuracy are a basic requirement. After each test, your analysis device must clean the dosing needles residue-free. In other words: The faster you clean your dosing needles, the more analyses can be done in an hour. At the same time, you are able to handle high sample throughputs in a short period of time in order to work efficiently.

Discover how you can clean your dosing needles equally economically, quickly and reliably!

Top 3 challenges when cleaning dosing needles

How are dosing needles cleaned?

After each dosing operation, dosing needles must be cleaned from the inside and the outside residue-free. An air cushion prevents both cleaning agent and medium from entering the syringe pump, preventing its contamination.

Step 1
The needle is dipped in a cleaning solution, which cleans it on the outside.
Step 2
The inside of the needle is cleaned by pumping cleaning agent through the needle.

Since Bürkert system components work so well together, you can speed up your cleaning processes.

Greater efficiency thanks to faster cleaning processes

The Bürkert solution ensures error-free and fast test results: Our valves are designed to enable high flow rates and to switch with exceptional precision. This allows you to speed up your cleaning process – while maintaining the same quality of cleaning. The result is efficiency at its best.

How can you profit from a high Kv value?

The Kv value is also referred to as the flow coefficient. It indicates the calculated quantity of liquid or gas that can flow through an open valve in a given period of time.

Saving costs: If the flow coefficient is high, less pressure drop is required to convey gases or liquids through the valve. This allows you to reduce or minimise pumps and compressors and to save costs.

Our solutions ensure greater reliability

Cleaning dosing needles efficiently

We have optimised the Bürkert system components to enable faster cleaning and higher sample throughput. Calculate it yourself!

Let us assume that your analysis device manages 2,400 tests in an hour. This means that an individual cycle, including cleaning, takes 1.5 seconds. Because Bürkert valves have a higher flow coefficient, they rinse up to 20% faster – managing one cycle in just 1.2 seconds instead of 1.5, for example. Calculated over the space of an hour, you can perform an additional 600 tests and cleaning cycles with Bürkert valves. The result: Higher sample throughput and greater efficiency for you.
