Shopping for pharma, cosmetic, and chemical process equipment starts with a practical fork in the road: are you making a batch in a vessel, granulating a wet mix, transferring a viscous liquid, or blending dry powder? Each of these four stainless steel systems answers a different part of that process, and their listed prices spread from USD 1,195 to USD 18,000. Understanding which unit matches your operation matters more than the price alone.
Quick take
If your work centers on extraction, distillation, or laboratory-scale processing, the twin-column bioreactor vessel system is the most complete standalone setup. If you need controlled high-shear mixing and wet granulation, the high-shear mixer granulator gives you a modern control interface. For transferring product through sanitary lines, the Feldmeier pump is the most focused and least expensive unit. And for powder blending, the Teledyne Readco batch mixer is the direct fit.

Product notes
Stainless Steel Bioreactor/Fermenter Vessel System w/ Twin Columns, Lab Use
This is the only system here that arrives as a multi-component assembly: a large stainless reactor vessel, dual vertical processing columns, pressure gauges, sanitary tri-clamp fittings, valves, and associated plumbing all on a mobile aluminum frame. If your project involves botanical extraction, solvent recovery, or chemical processing research, this gives you a connected process train rather than a single component. It is listed as pre-owned and intended for biological laboratory work. The main limitation is the USD 18,000 listed price-the highest in this set-and the fact that you are purchasing an entire processing frame. If you already own columns or need only a simple fermenter, that completeness becomes unnecessary.
Stainless Steel High Shear Mixer Granulator with PLC Touch Control Panel
If wet granulation or uniform emulsions are on your agenda, this stainless steel unit pairs a bottom-driven sweep impeller with a high-speed side chopper/homogenizer blade. Its PLC touch screen lets you adjust agitation speeds and oil heating parameters from the panel, which is a step up from manual operation. The unit is listed as seller refurbished, so the condition is worth noting even though the stainless construction is heavy-gauge and mirror-polished. At USD 9,900, it sits between the pump and the bioreactor in price. It is not a dry powder blender-its strength is high-shear mixing, granulating, and dispersion where you need uniform particle or droplet size. Choose this when the process needs control and repeatability more than a mobile frame.
FELDMEIER 3HP STAINLESS STEEL PHARMACEUTICAL PUMP - BOSTON GEAR - SANITARY/ FOOD
For controlled transfer of viscous or sanitary product, the Feldmeier pump is the most direct tool here. The integrated Boston Gear drive reducer provides torque multiplication and smoother output speed control, which matters when you are moving product through process piping. It is listed as used and was removed from a pharmaceutical processing environment; the title also points to sanitary/food use. At USD 1,195, it is the lowest listed price in the comparison and the only unit devoted to pumping rather than vessel processing. The trade-off is that it cannot mix, granulate, or blend on its own. If your operation already has process vessels and simply needs a reliable sanitary transfer component, this keeps the investment concentrated.
ReadCo 40 ft³ Stainless CBM Containerized Batch Powder Blending/Mixing Tank
For dry powder work, the Teledyne Readco containerized batch mixer has a different design: a 40 ft³ stainless vessel with a high-speed impeller inside a contained module. The removable stainless-steel vessels allow quick change-out and cleaning, and the contained process modules are aimed at minimizing cross-contamination between batches. The unit is listed as used and priced at USD 5,000, placing it in the middle of the range. One detail in the listing says the unit may or may not have the perforated guard around the top shaft-useful to consider if that guard matters for your operation. This is the system to pick when your bottleneck is powder blending and you want a modular, easily cleanable batch path.
Final recommendation by use case
The right choice depends on the process step you are equipping:
- For a complete lab-scale processing train-extraction, distillation, solvent recovery-the twin-column bioreactor vessel system justifies its top price with columns, plumbing, and mobility.
- For wet granulation and emulsion work, the mixer granulator is the modern choice, with touch-panel control and a refurbished-condition caveat.
- For sanitary liquid transfer, the Feldmeier pump is the lowest-priced way to get a 3 HP stainless pump into your line.
- For batch powder blending with fast change-out, the ReadCo 40 ft³ containerized batch mixer delivers modular stainless vessels at a mid-range price.
No single system covers all four jobs. Match the equipment to the process step, not the other way around.
