Cole-Parmer Submarine Gel System 2-Place Gel Caster Tray for 28561-00

Gel Casters allow you to precast consistently flat, even gels using the gel trays sold seperately. Casters accommodate either one or two trays. Casters feature a three-point leveling base and soft, coated neoprene side gaskets that secure trays in place and effectively seal their ends during casting — eliminating the need for taping.
