Durable. Dependable. Design you can trust.

This 7-position Model 305 apparatus meets all requirements of ASTM D1401 and related water separability (demulsability) methods, making this apparatus both a time saver and a reliable test device. Equipped with built-in timers and an audible alarm to indicate when agitation has stopped, a color touch panel controls the unit and displays temperature at a resolution of 0.1 C. Measured by a tachometer and also digitally displayed, the precision motor’s adjustable speed stirrer operates at 1500 rpm 1 rpm. The glass jar heating bath has a range of 40 to 95 C and a stability of 0.1 C.Additionally, fluctuations in AC line voltage have no effect on this stable device, in comparison with the AC motors of competitive units, which result in an undesirable change in speed.


Requiring no tedious belts or chains, this efficient unit’s stirrer motor is securely fixed with a vertical range of motion. An exclusive design allows lifting for paddle and sample removal, while proper testing alignment results in time efficiency. Machined from a single piece of stainless steel, the shaft and paddle reduce the possible micro crevices to avoid accumulation of contaminants  which are difficult to remove in conventional soldered shaft and paddle construction. Further, by keeping the motor fixed and through use of a sample turntable that locks in place at each position, future mechanical problems are avoided.


The enclosed cabinet design provides a footprint that boasts higher stability and safety in high temperature applications than accomplished with open jar designs. The bath jar is easily removable, and additional safeguards include low-level, over temperature, and circuit breaker protection. The bath cover reduces water loss and has the capacity for seven graduated test cylinders, while a backlit area allows for easier reading of the emulsion separation line.
