Review: Excelente cumplimiento y calidad de los productos
Review: Contaminated - We tried to use these for work, sampling air with a HAPSITE machine and even known 'clean' air (fresh outside air tested other ways) came back with high concentrations of chemicals. If they're actually unused tedlars I shouldn't be seeing the levels of contamination that we did for the chemical we sampled for. I ordered bags from our known distributor and had no issue, I got consistent low results for the same air source as before. I guess paying a bit more is worth knowing our supplier isn't shipping faulty or contaminated products.

## Features

- Capacity: 1 Liter - Size: 7'' x 9'' - Material: 2 mil Tedlar PVF film - MADE IN USA
- Our Tedlar bags utilize a patent pending 2-in-1 fitting. By combining a shut-off valve and Teflon-lined septum, you are able to fill the bag and remove the sample for analysis with one fitting. The stem is used to connect 1/8” ID tubing for filling and emptying the bag. The septum can be used for removing the sample using a syringe. Fittings are available in polypropylene, stainless steel, and Teflon.
- Guidelines: 1. Store Tedlar bags in a clean area away from potential contamination sources. 2. Tedlar bags are designed for use at atmospheric pressure. Over pressurization (>2 psi) can cause the bags to burst. 3. Always ensure the bag, fitting, and tubing materials are appropriate for the compounds being sampled. 4. CEL Scientific does not recommend reusing Tedlar bags in most cases.
- To fill the bag: 1. Connect the appropriate tubing (1/8” ID) from a sampling source to the stem on the side of the fitting. 2. Open the valve by holding the stem and turning the top portion of the fitting counterclockwise one turn. 3. When the bag is full (approx. 90% capacity), close the valve by holding the stem and turning the top portion of the fitting clockwise until it is finger tight.
- To withdraw the sample using a syringe: 1. Insert the needle into the red septum on the top of the fitting. 2. Withdraw the sample and remove the needle, the septum will reseal itself. (Do not allow the needle to pierce the Tedlar film on the back side of the bag)

### ⭐⭐⭐ Need to be careful to get the valve closed.
*by C***W on November 1, 2021*

Bags were ok, price is good, but I think it is hard to be 100% sure the valves are closed tight...
