Biopsy pads are no longer necessary with these innovative disposable plastic biopsy cassettes with a large compartment measuring 25 x 30 mm. Perfect even with needle biopsies since mesh holes have a diameter of only 0.26 mm while still allowing for maximum fluid exchange and drainage. Molded from a special high density polymer, these patented cassettes keep specimens safely submerged in liquid and are resistant to most histological solvents. They can be opened and closed as often as necessary and they always relock securely without danger of specimen loss. Available in 11 colors. Anterior writing area is at a 45° angle to make the cassette more suitable, to be used with certain types of cassette labeling instruments
