Polypropylene Faucets are manufactured from pure unpigmented
virgin Type I homopolymer per ASTM D 4101, using no anti-oxidants,
pigments or other foreign substances often associated with
other plastic piping products. This results in an ideal system
for the transportation of deionized or distilled water or
other liquids where a high degree of purity is required. Polypropylene's
smooth surfaces do not attract contaminants, so they do not
provide breeding places for bacteria and other biological
impurities.
Scientific's High Purity
systems features:
- no metallics in the system
- ability to withstand high temperatures
(210°F max.)
- excellent chemical resistance
- non-porous surfaces

Scientific
also offers Laboratory Faucets designed for Ultra high purity
applications. They are produced using high purity, unpigmented,
natural Kynar® PVDF (polyvinylidene fluoride) resin conforming
to ASTM D3222. Kynar is 100% pure PVDF containing no colorants
or stabilizing additives. Independent studies have demonstrated
that products manufactured from PVDF add no detectable leachants
or other contaminants to test solutions. PVDF meets the most
stringent industry requirements for extractables and purity
levels for 18 megohm deionized water.
PVDF also offers:
- Exceptional chemical and abrasion resistance
- Elevated temperature rating of 280°F
- High resistance to gamma radiation
- Total resistance to ultra-violet radiation
- Highly transparent to ultra-violet
radiation
- Will not support growth of fungi or
bacteria
- UL 94 V-0
