Western Blot Roller

The Thermo Scientific Western Blot Roller is a simple, reusable tool for gently and easily removing trapped air bubbles when assembling transfer stacks in semi-dry or wet-tank transfer cassettes.

The transfer-stack roller has a stainless steel handle and an inert PTFE roller that is 8.4 cm wide. Mini-gel sandwiches can be rolled out with one or two passes, but the tool also works well for transfer stacks with larger gels. The tool is included as an accessory with the Pierce Power Blotter (Part No. 22834).
