POLYTRON benchtop generators work via the Rotor/Stator System. Samples are drawn into the center of the generator tip where they are vigorously mixed, accelerated, and pressed through the narrow gap between the rotor and stator and finally forced out between the teeth of the stator.

	Designation	Description	Action
Shown without knives	/2	Standard Generator, with long slots in shaft tube, 1 rotating and 1 stationary ring	Maximizes aeration and turbulence
	M	Standard Generator with Knives*
	/4	Standard Generator with Flat Rotor, long slots in shaft, 2 rotating and 2 stationary rings	Maximizes aeration and turbulence for preparation of suspensions and emulsions only
	/6	Foam Reducing Generator with Flat Rotor, 3 rotating and 3 stationary rings	Minimizes aeration and foaming for preparation of very fine suspensions and emulsions only
Shown without knives	S	Standard Generator with Saw Teeth, long slots in shaft tube	Saw teeth shear samples, improve homogenization efficiency; long slots maximize aeration and turbulence
	SM	Standard Generator with Saw Teeth and Knives*
Shown with knives	T	Foam Reducing Generator, with small shaft slots	Minimizes aeration and foaming of large samples; operation in sealed environment via internal seals
	TM	Foam Reducing Generator with Knives*
Shown with knives	TS	Foam Reducing Generator with Saw Teeth	Small shaft slots minimize aeration and foaming; efficient operation in sealed environment
	TSM	Foam Reducing Generator with Saw Teeth and Knives*
	W	"W" Generator/Shredder	Efficient shredding of difficult-to-process samples (i.e. tough, brittle, fibrous, sticky, or gummy)
	Z	"Z" Generator, with unique geometry of stator teeth	Rapid processing of hard and brittle materials such as pharmaceutical tablets, pellets, grain, and beans
	EC	EasyCare Generators	Easy disassembly for thorough cleaning of generator

* Generators with knives are used for processing samples that require precutting and are larger than generator diameter.
