What is a magnetic mixer?

Basically a magnetic mixer is like a conventional mechanical mixer-it has a motor, a driveshaft, and mixing blades that mix stuff in a tank. The technical term for the mixing blade assembly in our mixers is "impeller." A propeller on a boat or an airplane is also a type of impeller. Impellers are designed to move liquids or gasses by rotating.
What makes a magnetic mixer different from a conventional mixing tank?
different from a conventional mixer is that the motor uses magnets to move the impeller. This works by attaching one set of magnets to the motor driveshaft and another set of magnets to the impeller.

What are our mixers used for?

There are many variables that can influence your impeller choice, but two variables that play a significant role. The first variable is the type of impeller: marine, Rushton, foil, axial, etc. The other is rotation speed. Most applications run our mixers at around 300 to 350 RPM using a high-flow impeller, like a marine or foil impeller, to maintain a homogenous temperature or composition throughout the entire tank. But there are applications that run as low as 50 to 150 RPM using a low-shear impeller to stir a viscous solution, or as high as 750 to 850 RPM using a Rushton impeller to disperse a gas into a solution.

In one case, a client of ours uses a tank to grow a fungus. They were previously using bottom-mounted mechanical mixers to disperse a gas into a solution, and running their mixers at very high speeds for as long as five days non-stop. This is very stressful on a mechanical seal. Every few weeks, the seal would fail and they would lose all of the mixture that was in the tank, plus the processing time required to get the new mixture to the point where it was when the seal failed. They estimated that each time the seal failed it cost them around $10,000 to $15,000-between the lost processing time, the lost product, and the time to get the seal replaced and get everything up and running again. They were losing a batch at least once a month. By switching to our magnetic mixer, they were able to eliminate that mechanical seal as the weak link in their process. Now they can just run their process, and they never lose a batch. Even though a magnetic mixer costs 4 to 7 times as much in up-front costs (compared to a mechanical mixer), they're saving more than that each month by eliminating the mechanical seal.

In another case, a client of ours uses a tank to collect and decontaminate infectious and hazardous organisms from laboratory effluent. This material has to be heated to a very high temperature for a long time before it is safe to dispose of. The primary function of the mixer in this tank is to maintain temperature throughout the entire tank. The mixer is required to be on the bottom of the tank for this application. If they put a mechanical mixer on the bottom of this tank and that seal fails, then they could have a significant hazardous waste spill. This is not only a health and safety issue, but, again, it costs them time and money to clean up, and risks putting them in violation of safety regulations. They decided that their best choice for this application was to use a magnetic mixer, because it is designed to work at the bottom of a tank without providing an opportunity for the tank contents to leak from a mechanical seal.

What sizes do our mixers come in?

Currently, the smallest mixer we have drives 20 inch-pounds of torque, and is about 3 inches in diameter at its narrowest point. We have used that mixer in tanks as small as 1.2 liters and as large as 350 liters. We are just finishing design work on what will be our largest unit, which will drive 1600 inch-pounds of torque. Depending on what level of agitation you are looking for, it will have the capability to mix up to 20,000 liters.
