SC475 — Polypropylene Screw Cap Digestion Vessels for
Use With HotBlock™ Pro™ SC181
These carefully engineered digestion vessels provide premium performance in your
HotBlock™ Pro™. Molded of claried homopolymer polypropylene, these vessels provide a
higher working temperature and greater chemical resistance than commonly used co-
polymer polypropylene. Each vessel is graduated to 50mL and has a total capacity of 68mL.
Molded-in graduations are extremely accurate, allowing analysts to easily reproduce volumes
to within 0.5%. Using the graduated vessels for sample measurement reduces the need for
graduated cylinders and volumetric asks and eliminates sample transfers. The result is a
“one-cup” system that greatly reduces labor and costs associated with metals preparation.
The 33mm threaded cap is lined with a 0.040” polyethylene faced foam liner for a leak-proof
seal. Only the metals-free polyethylene liner comes into contact with the sample. SC475
vessels come in cases of 500 and are packaged to ship as a standard size UPS package,
keeping shipping costs at a minimum. Vessels come standard with green caps. White caps
are also available (SC480-W).
• Certied for low metals background • Compact packaging reduces shipping costs
• Lined closure system ensures leak-free • Accurate graduations eliminate the need
performance with no contamination for graduated cylinders
SC505 — Ribbed Watch Glasses
44mm ribbed watch glasses t all 50mL digestion vessels. Polypropylene construction is naturally free of
contaminant’s. Ribbed design allows partial reux during digestion. Watch glass has a center stem to aid in
handling. Pack of 1,000.
SC506 — Reux Caps
Special cap has a 0.5” hole in its center to allow the addition of reagents while cap
remains in place on the SC475 digestion vessel. The reux cap does not have to be removed
during the digestion process. The cap is not ribbed, but ts over the top of the SC475 diges-
tion vessel to maintain a centered position. Tests have shown equal reux between SC506
reux cap and SC505 watch glass. Pack of 1000.
SC200 — Polycarbonate Transfer Racks
Each sample transfer rack for the HotBlock™ is de-
signed to hold and handle eighteen SC475 50mL digestion
vessels. Racks are made of polycarbonate for heat and acid
resistance and t over the HotBlock™ to facilitate handling
of samples and improve temperature and evaporation
uniformity.
SC446 — Plastic Storage Racks (not pictured)
24 cup capacity plastic racks neatly hold the SC475
digestion cup. Made of polypropylene, racks accommodate
any tube up to 30mm and are stackable for efcient storage.
