Electrophoresis gels and membranes can be easily stained, fixed, destained and handled in these boxes supplied with snap fit lids. The boxes have a drain (with LDPE plug) lower than the floor of the box to minimize disturbance of the gel during liquid drainage. The box and cover are unaffected by temperatures from -70°C to +70°C and are resistant to acids, alkalies and many solvents. Inside dimensions of the boxes are 12.7 x 12.7 x 5.1cm deep (5 x 5 x 2") offering liquid capacity up to 750mL. Select either the clear PMP box for easier viewing or the economical polypropylene box. Per each, 2 per case.
