Closed-flask incubation test setup 2 used for testing the biodegradation of 14C labeled tetralin and decane in soil using guideline OECD 307. The test design consisted of a 100 mL glass flask with 50 g (dry matter) of soil with an internal CO2 absorbing flask and a permanently hanging tenax tube for passively trapping the volatile fraction. The entire test design was closed using a plastic-free stainless-steel lock system.
