Tween® 20, Molecular Grade, is a nonionic detergent used for many different molecular biology applications. Quality Tested: Each lot of Tween® 20 is tested and certified to be free of DNase, RNase and protease activity.
Due to difficulties in sourcing for the usual 500mL amber bottle, the manufacturer has temporarily packaged the Tween® 20, 500mL in a 1L natural color bottle (non-amber). For items packaged in a non-amber natural color 1L bottle, it should be half-full. Please be assured that the volume and properties of the H5151 Tween® 20, 500mL remains the same, unaffected by this temporary change in packaging.
