Brand bottle-top dispenser, Dispensette®S, Trace Analysis, DE-M, tantalum spring, 1–10 ml, without RDV, #4640240

"The Dispensette ® S Trace Analysis is ideal for the precise volumetric dispensing of high-purity media in trace analysis. It can be used as a hydrofluoric acid dispenser with a Pt/Ir valve spring.

General characteristics of the Dispensette ® S Trace Analysis bottle-mounted dispenser:

The plastics in contact with the media are made from high-purity materials such as PTFE, ETFE, FEP and PFA. The replaceable valves are made from the purest sapphire. Depending on requirements, platinum-iridium or tantalum are available as spring materials.

A tried-and-tested cleaning procedure to be carried out prior to use in trace analysis is described in the user manual.

If contamination of the bottle’s contents is to be avoided, we recommend using the device without the backflow valve.

The GL 45 thread and the adaptors supplied fit the most common reagent bottles.

The bottle label remains visible at all times thanks to the 360° rotatable valve block.

Telescopic suction tube adjustable to different bottle heights.

Can be easily dismantled to replace the dispensing unit."
