RH Pump Head
Ceramic or Zirconia Piston & Ceramic Cylinder Liner
Ideal for Laboratory, Analytical, Industrial and OEM applications
The RH pump head stands out for its durability due to its high-quality corrosion resistant materials. Its single moving part design, minimizes drift over time, providing millions of cycles of reliable, repeatable pumping.
- Capable of repetitive dispensing with a coefficient of variation (CV) of less than or equal to 0.5%.
- Small displacement – fully adjustable from zero to maximum.
- With no valves to clog or leak, maintenance and downtime are significantly reduced.
