Dispensette S Trace Analysis Bottletop Dispenser (Ta Recirculating Valve) 1-10 mL

The Dispensette^® S Trace Analysis is the next generation bottletop dispenser for precise volume dispensing of high-purity media for trace analysis. It is especially suited for dispensing acids, bases and hydrogen peroxide in the volume range from 1 to 10 mL. The components of the fluid path have been selected to only contain the highest purity materials, such as fluoroplastics and sapphire. The result is a trace metal content of dispensed liquid generally in the low ppb range, or even in the low ppt range, depending on the application. Both platinum-iridium and tantalum valve springs are available for application compatibility.

For >70% nitric acid, select 4640241 or 4640041 (see compatibility chart to select Ta or Pt-Ir recirc valve)
