To simplify the operational qualification of microplate readers Starna has released a new Reference Cell Microplate Adaptor (RCMA) that now enables laboratory professionals to use existing Starna sealed-cell and filter reference materials in a horizontal format.The RCMA’s innovative design allows the location of eight ‘pairs’ of read positions, and minimises the potential for bubble interference adversely impacting measurements. The new adaptor, which provides a method of validation in the UV region that has not previously been available, enables companies to extend their ‘NIST traceable’ and ISO 17025/ISO Guide 34 accredited Certified Reference Materials for use in a micro-plate format.
