This B1A-10 double-sided comb has 10 teeth, each with a thickness of 1.0/1.5mm and a width of 4.7mm. It is designed for use with the Owl® B1A Mini Gel And A2-OK Opossum™ Multiple Gel Horizontal Electrophoresis Systems. Double-sided molded combs combine 1.0mm and 1.5mm tooth thickness on one comb. Double-sided combs provide greater precision due to the exact manufacturing technique which provides greater control over tooth size and spacing than the traditional machining methods. The number of teeth and arrows that point to the designated thickness is molded onto the spine for easy identification. A raised section of the spine helps the user grip the comb when removing it from the gel. The B1A-10 comb is molded from durable polycarbonate that holds up through years of use.
