Millipore has enhanced the design of its Stericup Filter Cups. The fast flowing, low protein-binding cups sterilize tissue culture media, buffers and other aqueous solutions. A new ergonomic design incorporates recessed finger grips on the receiver flask that make it easier to hold, minimize slippage and facilitate lab procedures. Volume markings on the side are accurate and consistent with standard products. Bottle attachment threads are slightly recessed for added protection against contamination. The redesigned cups are available in 150 mL, 250 mL, 500 mL, and 1L volumes.
