PFA sample tanks and vials with threaded closures designed primarily for storage of samples. 
Available with flat, conical and rounded inner style configurations. 
Some tanks vials jars are molded with solid outside bottoms for use on hot plates.
CFDPLAS PFA vials have been the best choice for demanding trace metal applications, and are used in laboratories worldwide for sample preparation and storage.  
The flat bottom and high service temperature range makes them ideal for use directly on a hot plate. 
Molded from high purity virgin PFA, they are chemically inert, with ultra low trace metal content.
Some specialty PFA vials are primarily used for sample preparation in geochemistry.
PFA sample tanks vials jars Features Properties:
Excellent temperatures stability:

PFA trace analysis labware maintains its stability in temperatures from -200°C to 250°C (-328°F to 482°F).
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.

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.
Superior chemical resistance:

PFA is inert with most reagents, including the 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.
