Rotary Laboratory Mixer

Model EL655 - Programmable Inversion Tumbler

The EL655 Programmable Inversion Tumbler is designed to mix wet or dry samples, gently for suspensions, culturing and dry blending or more aggressively by programing the tumbler to rotate clockwise stopping and then rotating counterclockwise. It is useful in keeping insoluble particles in suspension to minimize the introduction of air into the solution, dry blending powders as well as aggressively agitating chemicals. In addition, it can also be used in liquid/liquid extractions in situations where typical vigorous shaking is inappropriate (i.e. if you don't want to introduce air into the solutions). The EL655 Programmable Inversion Tumbler can also be used to blend dry powders. The standard unit accepts 6 bottles or jars up to 7\" in height. An interlocked safety switch on the door is supplied with the unit along with a new upgraded aluminum plate base with integrated handles for ease of moving.

Model EL665 - Heavy Duty Programmable Inversion Tumbler
The EL665 Programmable Inversion Tumbler is designed to mix wet or dry samples, gently for suspensions, culturing and dry blending or more aggressively by programing the tumbler to rotate clockwise stopping and then rotating counterclockwise.
The EL665 is designed with a continuous duty cycle rated stepper motor, this machine can handle continuous use of unbalanced loads which is often the case when not all the containers are loaded or filled to the same level.
