A new sample handling system from Beckman Coulter, Inc. reduces minimum volume requirements on the Multisizer 4 COULTER COUNTER Particle Characterization System from 10 mL to 4 mL.
The new adapter, available worldwide and immediately, accommodates Nalgene* 5 mL polyethylene vials and will address the volume range important to customers who are sensitive to sample size and dilution effects. The ability to accept smaller volumes is critical 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. "We're glad to have developed this new adapter and excited about the opportunities it presents to researchers."
"While the protein formulation market motivated us to begin this project, we quickly realized the new vials could be used by cell biologists, chemists and geologists -- any customers with precious samples," said Matthew Rhyner, Ph.D., Beckman Coulter technical marketing manager.
