Question/Answer

For EPA 1664, it appears that your company sells 1000 mL glass reservoirs or 250 mL PVC funnels for each station. Why is the capacity only 250 mL for the PVC & not 1000 mL like the glass system?

We mold the 250 mL funnel here at Environmental Express. The same funnel is used in other products we manufacture which don’t require a 1000 mL capacacity. It is more cost effective and efficient to mold the one size funnel than to mold two separate sizes.

With the StepSaver system, what is the approximate volume of hexane needed to elute the O and G from a 1 L sample?

We suggest washing the filter with 15 mLs of hexane three times.
