Product Description

CFDPLAS’s Polypropylene block digestion tubes are the cleanest and highest performing block digestion tubes available.

Molded from only the highest purity grades of Polypropylene, they are cleaner,giving a lower trace metal background – important for digestions that are to be analyzed by ICP-MS.

Polypropylene is the ultimate choice of material for block digestion tubes because it has a high working temperature range and is inert to all strong mineral acids (including HF), inorganic bases, inorganic oxidizing agents, salt solutions and organics.

Design Features:

CFDPLAS Polypropylene block digestion tubes are thin walled and translucent-making them much more convenient for use than PTFE tubes,which are clear.

These digestion tubes are molded of clarified homopolymer polypropylene assuring higher working temperatures and providing great chemical resistance.Graduation lines are on both sides of the tube. Includes green, polyethylene-faced lined cap. Flat bottom (30 mm OD) (500PCS/PK).

The translucency of CFDPLAS polypropylene tubes,making it easy to see the liquid level inside and also check for undissolved solids in the bottom of the tube.

The flat base and thin side walls offer excellent heat conductivity for fast, even heating, and the tubes fit into any standard block digestion system that accepts 50mL (nominal) tubes.

The working temperature range of Polypropylene is -200℃ to 135℃, which allows the tubes to be used for high temperature block digestion methods. A Scribed graduation mark (ring) at 50mL is accurate to Class A specifications, and a molded collar below the thread allows the tubes to be lifted out of the digestion block using racks typically supplied by block manufacturers.

CFDPLAS tubes are cleaner than PTFE tubes with respect to trace metals, because they are injection molded from the highest purity grades of PP resin. In contrast, PTFE tubes are not molded, but manufactured from lower purity PTFE by machining, which can add metal contamination.

The smoother, injection molded surface finish of the CFDPLAS PP tubes also makes them easier to clean after each use.
