TFM Deflation screw application on microwave digestion systems:

Remove the deflation screw from the standard seal lid. Check the deflation hole to ensure the passage is free. Use the diaphragm tweezers to put one safety diaphragm into the socket (recess) of the deflation screw (Only one specialized safety diaphragm is allowed). Make sure that the safety diaphragm is placed flat in the socket and tail node toward the gap. Then twist the deflation screw into the threaded hole of the seal lid. During twisting the screw, rotate it to the end until the screw is tightened to compress the safety diaphragm to prevent gas leakage.

However,do not over tighten the screw to avoid thread stripping. The seal of the safety diaphragm is very important since the leakage caused by diaphragm seal failure will lead to the inconsistent pressure and temperature between standard vessels and control vessel, which will result in experiment failure.

CFDPLAS customized PTFE parts can resists almost all corrosive chemicals,including organic solvents,acid and base.

As PTFE is one of the most thermally stable plastic materials, these machined parts and molding products have no appreciable decomposition at 260°C.

PTFE products have resistance to acid, base, and most other corrosion chemicals.

It has great flexibility at low temperatures and thermal stability at high temperatures, allowing this material to be applied in a lot of industries.

PTFE also offers high strength and moisture, temperature, and thermal expansion resistance.

PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine.

PTFE is used as a non-stick coating for pans and other cookware.

PTFE is used for wiring in aerospace, computer applications, plain bearings, gears, and slide plates,

PTFE is often used as the liner in hose assemblies, expansion joints, and industrial pipelines, particularly in applications using acids, alkalis, or other chemicals.

CFDPLAS supplies a wide range of PTFE products such as PTFE bushings, PTFE Beakers, PTFE plate/sheet/board, PTFE Key Stopcocks, PTFE Coated Magnetic Stir Bar,s and PTFE Bottles.
