The MTC Bio B1200-7BK Rectangle Western Blot Box, 3 1/2 x 2 9/16 x 1 in., Opaque Black, Pack of 5, is correctly matched to common blot sizes, allowing you to fit more blots on shakers/rockers while keeping reagent and antibody usage to an absolute minimum. Additionally, all corners are formed at 90˚ angles and the bottom surface is uniformly flat, further reducing consumption of costly reagents and antibodies.

The blot boxes are engineered from polystyrene and are an opaque black color that protects light sensitive samples. The boxes are equipped with an easy-to-open hinged lid that reduces evaporation.
