'The Digest n-Vessel is a high purity PFA semi-closed
digestion vessel for the non-pressurised digestion of samples utilising a
reflux method. The vessel comprises a lower digestion section screwed on to an
upper reflux section incorporating a condensing n-tube permitting the
continuous refluxing of the digest acid.
·
Made of high purity PFA for ultra-trace analysis
·
Digest samples safely with easy handling and cleaning of vessels
·
Reduced acid consumption and acid vapour pollution
·
Compact design for multiple sample digestions
·
Reduced foaming compared to glass digestion vessels
·
Can be heated with repeated cycling up to 260oC
·
Ideal for volatile elements like Hg, As, B
The Digest n-Vessel is ideal for the
trace elemental analysis of geological, environmental and biological samples
with large sample weights and with a wide variety of acids.
As the sample is digested the acid vapour passes from the
lower digestion section through to the upper reflux section where it condenses
in the n-tube and accumulates in the collection tube. Once all the acid in the
lower digestion section is vaporised and condensed in the upper collection
tube, the pressure falls and the condensed acid is released back in to the
lower digestion section allowing the process to be repeated until the sample
digestion is complete. The upper reflux section includes a smaller opening at the
top that allows additional acids/reagents to be added during the digestion
process and also acts as a vent for any exhaust vapours.
