What is a main advantage of using a Teflon jar when collecting samples?

Using a Teflon jar for collecting samples is particularly advantageous due to its resistance to a wide range of chemicals. Teflon, or fluoropolymer, is known for its inert properties, meaning it does not react with many chemicals present in wastewater, which ensures that the integrity of the sample is maintained. This characteristic helps in obtaining accurate readings and analyses of the water quality by preventing contamination or alteration of the sample. While easy cleaning, cost-effectiveness, and transparency are beneficial in other contexts, the primary benefit of using Teflon is its chemical resistance, allowing for reliable and precise monitoring of wastewater without the risk of leaching substances from the container into the sample.
