Abstract:
A chemical sample loading station for loading sample solutions in a sample funnel of a chemical treatment cassette, comprising in operative combination:a) a cassette alignment means for aligning the chemical treatment cassette to a predetermined X-Y position;b) a sealing gasket exerting compressive force to provide a leak-proof seal between said sealing gasket and a first open end of said funnel, said sealing gasket permitting introduction of sample solution or solvent into said funnel without having to disengage said sealing gasket from said sample funnel; andc) a pressure cap having an annular shoulder and center plunger section for press-fit insertion into a mouth of said sample funnel to define a funnel headspace, said shoulder engaging said sealing gasket to limit the extent of insertion of said center plunger section, said pressure cap having a through-bore gas inlet for introduction of a pressurized gas into said funnel headspace to force said sample solution into a through-hole of a conical second end of said sample funnel.
