  • Product Name
  • "STFQ"Micro volume adjustable displacement dispenser pump
  • Item
  • STFQ
  • Brief Introduction：
  • Diagnostics/IVD, Medical, Biotechnology, and Analytical Instrumentation
  • The STFQ is an advanced minuaturized fluidic system designed to control small volumes of fluid at the microscale level for a broad range of applications. It is currently available in standard drive configurations ranging from 250 µL through1.25 mL in 1 µL increments. Standard pump head options are available with various sealing options and diameters.
    Achieving optimal performance in accuracy and repeatability with innovative design modifications, this product enables the ability to do precision microliter dispensing
