PFA LABWARE - PROPERTIES AND ADVANTAGES
DescriptionPFA (perfluoralkoxy) is a fluoropolymer with very low friction coefficient.
Thanks to its flexibility, high resistance to acids and optical tanslucence, this material can be used in the more corrosive environments.
The essential features are the following:
EXCELLENT TEMPERATURE STABILITY
PFA trace analysis labware maintains its stability at temperatures from -200 ºC to 260 ºC (-328 ºF to 500 ºF).
NO LEACHABLE METALS
PFA is manufactured without metals such as calcium, aluminum, iron, magnesium, nickel, copper, manganese or zinc. These metals can leach into samples from other containers, and contaminate samples.
SUPERIOR CHEMICAL RESISTANCE
PFA is inert with most reagents, including nitric and hydrochloric acid routinely used in cleaning trace analysis labware. This stability significantly reduces the risk of cross-contamination.
EXCELLENT LONG-TERM STABILITY
PFA containers often extend the stability of low (ppb) concentration standards. Such stability reduces the time and cost of renewing trace analysis standard solutions.
HIGHLY TRANSLUCENT
Translucency is important for making accurate measurements using volumetric labware.
SIMPLIFIED CLEANING
Conventional labware for trace analysis requires time-consuming and expensive cleaning. The hydrophobic and anti- adhesive properties of the exceptionally smooth-surfaced PFA labware simplify the cleaning process, making it ideal for trace analysis.
