Our Owl Casting Dams can be used in conjunction with several of Owl's horizontal gel casting systems. Our Owl Casting Dam blocks off a portion of the UVT gel tray to allow shorter gels or gradient gels to be cast and run in one device -- eliminating the need for tape. This innovative design provides a fast and easy casting method with a durable and reliable electrophoresis system. It is manufactured using a high quality aluminum that seals the agarose upon contact. A knob and finger depressions provide easy maneuverability. Because our Owl Casting Dam is free standing, the chosen length is not restricted.
