The 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.

• Reusable
• Durable

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.
