Laboratory Mixers - BenchMix™

Laboratory Mixers from Admix a complete series of Benchtop Laboratory Mixers, ranging from 2 liter benchtop units to 10 gallon pilot plant floor models.

Laboratory Mixers are completely manufactured or enclosed in stainless steel for superior corrosion resistance, sanitation, and cleanability.

Laboratory Mixers provide predictable, repeatable results when scaling up Rotostat^® Emulsifiers or Rotosolver^® Dispersers from the development lab to pilot scale and full production, or can be used for small batch production only.

New for 2002! Admix introduces a revolutionary benchtop high shear lab mixer, specifically designed for product development, simulation and scale up. The OPLB-300 is the first lab mixer with scale up parameters and indicators built into the PLC controls, providing an accurate and repeatable method of scaling up from 1-2 liters to over 1,000 gallons. Information displayed on the OPLB-300 includes elapsed time, running speed (rpm), flow rate (gpm), tip speed (ft/sec) and mixing intensity.

Other features of our BenchMix series of benchtop lab mixers include:

• Available with 2 types of high shear mix heads and several size propellers to allow a complete range of testing
• Available with an electric lift stand for easier raising / lowering and mix head placement
• Glass bead finish stainless cabinet with 316SS shafting and mix heads
• Variable speed from 500 - 10,000 rpm through a brushless DC motor

How It Works

• Precision scale of lab size mixing heads allows for complete validation, process qualifications and Q/C analysis of pharmaceuticals, food components and cosmetic formulations.



• High intensity, 1/2 Hp DC brushless motor on benchtop models provide for a 500 to 10,000 rpm operation under a wide range of conditions (viscosity, density and percent of solids).



• The pilot plant models (XP-02 and RS-02) operate at 3600 rpm providing the ideal tip speed for most applications. Speed controllers are available as an option for reducing the mixing intensity in thinner formulas.



• The new OPLB-300 provides a digital display of tip speed, mixing intensity and pumping rates, allowing the operator to qualify and validate the process with as little as 1 to 12 liters (1/4 to 3 gallons), while providing the guidelines necessary to scale up to larger volumes.
