Peristaltic pumps from Watson-Marlow Bredel have been selected by the Mikura development team for their latest microplate instrumentation products.
Based in West Sussex, Mikura designs and manufactures laboratory equipment.
When specifying pumpheads for their new microplate instrumentation products, the company identified that it was critical to achieve accurate fluid transfer from an application that would be easy to clean and maintain.
Recognising the Watson-Marlow Bredel expertise in this area, the team selected a range of 400 series OEM peristaltic pumps, designed specifically with clinical, diagnostic, scientific and medical applications in mind.
Since launching the company in 1997, Mikura has developed a wide range of microplate instrumentation products for washing and filling applications in the immunoassay testing field.
Immunoassay testing is a laboratory technique used for scientific research and testing for diseases including HIV and Rubella.
The Autura 1000 and 500 automated microplate washing and filling machines from Mikura rely on Watson-Marlow Bredel's peristaltic pumps to perform the primary functions of filling and cleaning test tubes.
The Autura 500 microplate filler uses two 8-channel 400 series peristaltic pumpheads mounted on the exterior.
The peristaltic pumps transfer small amounts of fluid from bottles via silicone tubing, into the top of the filler head where all the tubes are held in the correct array for dispensing into the test plate.
The Autura 1000 microplate washer washes out any unbound antibodies and reagents using three bespoke 400 series pumpheads with two channels.
Using specially designed coaxial tubing and Watson-Marlow Bredel peristaltic pump technology, the wash buffer can be simultaneously dispensed and aspirated through the one-washer head.
Low to medium flow fluid metering is an important function of Mikura's microplate instrumentation products.
According to Andy Cain, Director of Mikura, accuracy is critical for the process since immunoassay testing involves extensive fluid transfers of wash buffers and reagents in small quantities, which need to be applied in exact amounts to achieve correct positive or negative readings.
He added that easy cleaning and maintenance was another very important factor to consider in medical device technology design, which made them consider peristaltic pumps from Watson-Marlow Bredel.
Mr Cain says that the pumps needed to meet the specifications of low dosing and easy cleaning, whilst offering reliable performance.
The 400 series pumps from Watson-Marlow Bredel have a modular design, which allow a large number of standard versions and the ability to provide a customised solution.
