September 11, 2020Vacuum pumps are a versatile piece of laboratory equipment for suctioning via negative pressure. They are routinely used in biological sciences for filtration, distillation and concentration of volatile solvents, solid phase extraction, freeze drying, and more. Even though vacuum pumps share a common function, there are many considerations to take into account when choosing a new pump. The following article will explain some important attributes to look for when comparing different vacuum pumps.

July 30, 2020We 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.

July 28, 2020Choosing 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.

June 25, 2020Sterlitech is offering 2 new space-saving, all-in-one vacuum suction systems from Lafil. The Lafil series suctions system is a line of unique integrated suction systems that combines a vacuum source with a suction kit. Its compact design saves more bench space than other traditional ones. With a fence-like platform design, it can prevent a user from tipping over the suction bottle.

May 15, 2020“Who lives here now? and “Who lived here previously” are fundamental questions of biology, but observing living things in their natural habitats is not always so straightforward. Tracking down rare, elusive, and microscopic species through harsh or inaccessible environments has challenged biologists for centuries.

May 15, 2020The Rocker Lafil 200 vacuum suction system integrates a vacuum source with a 4L waste bottle and suction kit, saves 50% space and is ideal for large volume cell culture aspiration and reduces the number of times you have to empty the waste bottle.

April 13, 2020Did you know that you can observe osmosis with ingredients that might already be in your kitchen? With only an egg, vinegar, corn syrup, and food coloring, this fun science experiment can shine some light on the invisible but indispensable process of osmosis, reveal the power of the semipermeable membrane, and create colorful eggs just in time for Easter!

March 11, 2020Why Perform a Bubble Point Test? In the bubble point test, pore size rating is determined by measuring the lowest air pressure needed to overcome the surface tension between the wetting liquid and the membrane pores in a fully wetted membrane. This pressure level, known as the bubble point, is signaled by the first appearance of a steady stream of bubbles observed from a special disc filter holder through the downstream side of the membrane filter. The measured bubble point is then correlated to the membrane pore size diameter.

January 10, 2020Membrane Distillation (MD) is a relatively new and promising separation technology that is an alternative to more energy intensive methods such as reverse osmosis or distillation. MD is a thermally driven process where only vapor molecules transfer through a hydrophobic (water repellent), microporous membrane.
