Comb, Electrophoresis

Description (Brief)
This white plastic electrophoresis comb has five wide tines, one of which has been modified into two smaller tines.
Electrophoresis combs are used to create the wells in gels for electrophoresis, a technique that uses the electrical charges of molecules to separate them by their length. It is often used to analyze DNA fragments. When a gel is poured, a comb is inserted. After the gel solidifies, the comb is removed, leaving wells for samples.
