Consumables for the instrumental techniques include
reference samples, gaskets and seals, filters, nickel basins,
and other parts specific to each instrument.
For gravimetric techniques, we stock
an excellent WVTR (or MVTR) wax, used to seal the sample into
the cup. We also produce cups which are faster to prepare than
the wax-sealed cups, as they are closed with a set of finger screws.
This results in a fast sample loading, easy cleaning and thus
faster turnaround between sample sets. These are typically made
in stainless steel or anodised aluminium, but polymeric versions
are available where required.
We also stock some grades of semi-permeable membranes
for wet cup gravimetric testing, commonly used in the fabric industry
