  • Tempered glass body with 60 mm calibration length
  • Choice of 500 µL, 1.0 mL, 2.5 mL or a set of all three sizes
  • Stainless steel plunger with Teflon seal
  • Blunt-tipped 23 Gauge needle
  • Patented triple seal on the plunger gives superior leak protection and longevity
  • Superior Teflon seal on needle for better leak protection
  • All stainless steel parts are chemically passivated
  • ±1% accuracy and repeatability
  • Available replacement parts include replacement needle and seal, as well as replacement plungers.

Note: The accuracy of delivery over a given time period depends heavily on the syringe size. For microdialysis, always use the smallest possible syringe. This choice must be balanced against the total time planned for the experiment and the desired flow rate. A 500 µL syringe provides better accuracy than a 2.5 mL syringe at any given flow rate. Try to keep a variety of syringes on hand and use the smallest size possible. Using the BASi UniSwitch can extend the duration of a perfusion indefinitely.
