We have had customers say that they aren't getting any or very little suction from their Rocker Oil Free Vacuum pumps.   These pumps are designed to be operated upright, if they get turned on their side or upside down during operation the Float protector will be engaged.   Note: The float protector is to protect the pump from liquid being sucked into the sytem and destroying your pump.

Choosing a new vacuum pump for your lab requires balancing important considerations including cost/longevity, performance/versatility, and power/size, but it can be simple. This article compares two of Sterlitech’s leading chemically resistant pumps: the Chemker 300 and the Rocker 300C. Both pumps are manufactured by Rocker Scientific Co. and used for widespread applications in filtration technology.

As a long time leader in membrane and microfiltration technology, Sterlitech is always expanding our range of high-quality products. In a new partnership, Sterlitech is now launching cellQART ® Cell Culture Inserts!

Cell culture inserts support research and development across a broad range of tissue engineering and cell studies. The patented design of cellQART ® Cell Culture Inserts are RNase/DNase free, non-pyrogenic, ISO 9001 and ISO 13485 certified, easy to use, and compatible with all standard well-plates. The new line of inserts will be available in 6-well (4.5 cm2), 12-well (1.1 cm2), and 24-well (0.3 cm2) sizes. They come standard with PET membranes in clear or white.
