SCIENION AG has announced the launch of the sciLINER, the first dispenser to print lines on membranes with full visual drop detection.
With up to four channels, a minimum dispensing volume of 0.1 µl/cm and a flow rate of up to 8 ml/min the sciLINER represents an economical entry unit enabling the production of lateral flow devices or other membrane-based materials.
With its printing speed of 20 seconds per sheet it covers production from small to medium throughput. It can be operated in either aspirate dispense or bulk dispense modes to produce continuous lines with a width from 0.5 to 5 mm.
In contrast to current technologies, the sciLINER allows for the online monitoring of drop formation and offers integrated drop volume measuring.
Both are important features when sensitive biological materials such as antigens, antibodies or DNA are deposited on substrates used in the diagnostics industry.
The non-contact dispenser loads all membranes and flat targets with a size of up to 150 x 300 mm. “This is our first product specifically geared towards the point of care testing market”, says Dr. Holger Eickhoff, CEO of SCIENION AG.
Dr. Eickhoff continued, “As with all our technologies, this new technology does not only meet present needs for R&D efforts but, with drop control mechanisms, also forms the basis for a stable production of point of care tests based on membrane materials.”
Assays on membrane materials have become a very popular and versatile test format for rapid point of care diagnostics since their introduction in the mid-1980s. All kinds of biological samples can be tested, for example blood, serum, urine and, more recently, also saliva, sweat or tears if the sensitivity of the test is sufficient.
Typically these tests, especially in so called Lateral Flow Tests such as popular pregnancy strip tests (often referred to as “dipstick tests”) combine several advantages being quick and easy to use with no specific equipment required.
Eickhoff states: “Reproducibility in R&D and production is key to develop and produce reliable diagnostic tests. We are confident that the sciLINER, offering central dispense steps monitoring and control from test development to manufacturing, will help customers shorten time to market with their diagnostic products.”
The sciLINER will be exhibited at the SCIENION booth at MEDICA 2013, November 20-23 in Düsseldorf, Germany, booth 3A42 in hall 3.
