Tedlar? PVF Gas Sampling Bags—PP screw cap combo valve (TDL21S)

Tedlar? PVF Gas Sampling Bags Introduction

Tedlar gas sampling bags are accredited by regulatory agencies in different countries and widely used indoor air sampling, waste processing yard gas sampling, soil sampling and other environmental protection application. Our Tedlar sampling bags come with renovated, patented valves. The materials of the valves are Polycarbonate(PC) or Polytetrafluoroethylene(PTFE) or Polypropylene(PP); Depending on inlet orientation, there are two types of valves: one type is that the inlet in vertical to the film, the other one type is the inlet horizontal to the film, both valves have the same functionalities: has on/off function; has a sample cap with septum inside for syringe sampling purpose, both valves are easy to use. One advantage of horizontal valve(side opening) is touse less storage space.

Tedlar? PVF Gas Sampling Bags Features

? Low gas permeation levels

? High tensile strength

? Continuous temperature range from –98°F to 225°F

? Unaffected by the chemical components of gases commonly sampled, like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and mercaptans

? Excellent chemical resistance, corrosion resistance, organic solvent resistance, and low adsorption

? The water vapor osmotic quantity of Tedlar film is 13g/m2.24h.0.1MPa; and oxygen osmotic quantity is 114cc/m2.24h.0.1MPa (the data is measured value not guarantee value)

? Gas barrier property of Tedlar PVF film is superior to Teflon FEP film

? Less permeable than FEP, Kynar PVDF and Fluode

? Bags resist puncture in the field.

? Less expensive than FEP and Kynar PVDF film.

? Recommended in many EPA testing methods

Tedlar? PVF Gas Sampling Bags Applicable Scope

Tedlar? PVF film is strong, durable, and considered chemically inert to a wide range of compounds. Tedlar gas sampling bag can be used in high precsion PPM level analysis sampling, can sample and save all kinds of corrosive gas and liquid samples, and used to solid VOCs residual detection.

It is the ideal choice of the VOC detection, used to solid VOCs residual detection. Such as automobile engine, automotive parts, household items pollution detection.
