PFA Dropper bottle, 50ml

  • Code:700-550
  • Unit Amount:1

Product Details

The Savillex 50mL PFA dropper bottle is designed to precisely deliver liquids, producing small droplets with a narrow size range distribution.

Constructed entirely from PFA, the dropper bottle is suitable for the most challenging trace metals applications. Fine droplet control is achieved through the use of microbore PFA tubing that forms the liquid delivery tip. A PFA dust cover prevents airborne contamination and minimises evaporation. The Savillex 50mL PFA dropper bottle is perfect for delivering isotopic spike solutions in geochemistry, and for many other uses. 

  • All PFA construction – the only PFA dropper bottle available
  • Microbore PFA tip for fine droplet control
  • Average droplet size 15µL
  • Narrow droplet range: 13-18µL
  • PFA cover prevents contamination and minimises evaporation
  • Perfect for delivering isotope spike solutions and many other uses

Technical note on the 50ml PFA dropper bottle



Droplet Size and Range

The Savillex dropper bottle was compared to an alternative (FEP) dropper bottle. Droplet size (volume) range and mean were studied, using 1% HNO3 as a delivery liquid, at 20oC: for each bottle, 20 droplets were produced and weighed. The results are shown below:

Note that the mean droplet size of the Savillex is smaller, but more importantly, the size range of the droplets produced is significantly narrower. This allows spike solutions – and any standard or reagent - to be accurately and reproducibly delivered.
