Description
Owl™ Casting Dams - 23 cm are high-quality aluminium casting dams that block off a portion of the gel tray, allowing shorter gels or gradient gels to be cast and run efficiently. They seal agarose on contact and eliminate the need for tape, while remaining free of the gel tray so gels of any length can be poured. A knob or finger depressions make the dam easy to handle and manoeuvre during setup. Designed to block off part of a UVT gel tray, this 23 cm model is intended for use with Owl™ systems. Offered as a single piece, the casting dam from manufacturer Thermo Scientific is a practical accessory for electrophoresis laboratories that need flexible gel lengths and clean agarose sealing without tape. Its aluminium build and simple placement support reproducible casting of shorter or gradient gels across routine molecular biology and analytical workflows.

A gel, a comb and a casting tray make the slab a sample runs through. Agarose percentage, or the acrylamide mix, sets the sieve. The comb thickness and the number of teeth set the wells. Precast and hand-cast gels are different products. A comb for a different tray does not seal.
Electrophoresis pulls charged molecules through a gel. Smaller ones move farther. Agarose gels separate nucleic acids. Polyacrylamide gels separate proteins. A comb forms the wells. A power supply holds the voltage or the current. The gel percentage is the sieve. A marker lane is how the bands are named. The methods are in the PubMed literature. Sequences of the nucleic acids are on NCBI Nucleotide.
