Baggie
for Gravimetric Procedures
Alternatives
To Glass Beakers - Thermoformed Cylinders Made With Teflon® Film
As stack emissions are
reduced due to more efficient control technologies, more laboratory analysts
are recognizing the utility of Baggies made with Teflon® film for gravimetric measurements
of stack gas samples. Baggies made with Teflon® film are an alternative to glass beakers
when processing samples from a Method 5-type sampling train or cascade
impactor with numerous advantages
- No recleaning costs
- Disposable
- Transparent
- Chemically
inert
surfaces
- Smaller sample-to-container
weight ratios for accurate measurements
- Unsurpassed archival
abilities avoiding sample loss
- Pliable
and unbreakable
- Extreme
temperature resistance
All Baggies made with Teflon® film are produced using DuPont Teflon® 7.5mil film through the process of thermoforming.
