Hi, Just having a few tube traps but don't know where is the starting and end point of relect or absorb side. I know that half of the trap is reflect, and the orther half is absorb but don't know where to start with. Thanks for your help! Tran
Do your traps have a small silver button (maybe 1/8 to 1/4" in diameter) on the bottom at any point? If so, that is the middle of the reflective side as I understand it. I have the Super Traps and this is how mine are.
The silver button indicates the reflective side as correctly stated by Fmpnd. However, if these are original ASC tube traps & well maintained then there should be a sticker on one of the end caps that clearly states which hemisphere is absorptive & which is reflective. FWIW.
