A sample handling system has been developed to reduce minimum volume requirements from 10ml to 4ml on the Beckman Coulter Multisizer 4 particle characterisation system.
The new adapter accommodates Nalgene 5ml polyethylene vials and will address a volume range for customers that are sensitive to sample size and dilution effects.
The ability to accept smaller volumes is required in applications in which samples are rare, expensive, or both.
'Customers using the Multisizer 4 for counting particles in protein formulations, in applications such as pharmaceutical development, needed to work with smaller sample volumes,' said Elsa Burgess, director of worldwide operations for the Particle Characterization Business Center.
'While the protein formulation market motivated this project, we quickly realised the new vials could be used by cell biologists, chemists and geologists - any customers with precious samples,' added Matthew Rhyner, technical marketing manager, Beckman Coulter.
The Beckman Multisizer 4 Coulter Counter particle characterisation system for particle counting and sizing is available from Meritics.
