Sub-1: Ultra-Low Volume Sub-Microliter Dispensing Pump

SKU:
Sub-1
Fluid Metering, Pumps, Sub-1

Description

The Sub-1 offers precision ultra-low volume sub-microliter dispensing. A precision stepper motor drives the pump, and piston stroke displacement is adjusted using an easy-grip flow control ring graduated in 450 divisions. The low dead volume pump head design ensures maximum bubble clearing and provides a typical stroke-to-stroke precision of 1% or better.

The Sub-1 is ideal for Medical Diagnostics, Biomedical and Analytical Instrumentation.
