Ball plunger for flow cytometry instrument:
The application of stainless steel plunger on special occasions The stainless steel plunger has strong anti-rust and anti-corrosion properties, which is very suitable for some special applications.
The stainless steel plunger applied to the flow cytometer The customer is an international biomedical company located on the west coast of the United States. It has a research and development center in Shanghai and a manufacturing center in Wuxi. It has products for flow cytometry and has its own brand.
In 2018, the company received feedback that a batch of flow cytometers failed, and it was found that the plunger in the instrument was rusted because of long-term immersion in salt water. And there are no drawings in the company's hands, only simple size information.
For us, we need to solve the problem of plunger rust in salt water, and design qualified products based on simple dimensional information, and the spring also needs to meet specifications.
solution:Through experiments, we changed the original material from SUS304 to SUS316, designed drawings based on simple size information, and produced products.
Our design ideas have been approved by the client company. After receiving the samples we gave, after testing, our plunger meets their needs in terms of corrosion resistance and elasticity.
product advantages:High strength: Our products have maintained the advantages of high strength.
Corrosion resistance: made of SUS316 material, resistant to salt water corrosion.
