Disposable plastic cassettes give you the option of pouring your own special gel type, while still enjoying the advantages of the XCell SureLock™ Mini-Cell. All cassettes are sealed on three sides to prevent leaking. They are available in two thicknesses (1.0 mm and 1.5 mm) and can be used with seven Novex® comb types (1 well, 2 well, 5 well, 10 well, 12 well, 15 well, and 2D well). Since Novex® empty cassettes are pre-sealed with the slot pre-taped, a bulky casting stand is not necessary.
