Non-aerating Upward Flow Stirrer

Item #: 21024

Normal Availability: 4-5 business days

Product Description

The upward flow stirrer mixes without introducing air (see this animated diagram). The unique, continuous-shearing and blending action occurs entirely below the solution's surface, creating a thorough mixing action without foaming or splashing. Even at high speeds in nearly full containers, there is minimal surface disturbance.

The upward flow stirrer may be used effectively in many procedures. It may be used with pharmaceuticals, cosmetics, paints, inks, petroleum, and foods. It is also useful in stirring hot and cold solutions in small or large volumes. It can provide rapid disbursement or re-suspension of heat-sensitive substances, proteins, oils, or food essences. It also emulsifies liquids of different densities, dissolves low-soluble solids, and resuspends bacteria into solution. Operation in open containers of all sizes is possible.

All wetted parts are made of corrosion-resistant stainless steel, which allows easy cleaning. The self-lubricating Teflon TFE bushing requires no maintenance and adds to the stirrer's long life. The shielded stirring blades cannot damage the mixing vessel.

This is the motor drive unit only.  It requires an upper flow attachment which is sold separately - choose from 2 sizes, item #'s 21025-A and 21025-B. The laboratory stand is not included but the lab clamp and control are included.  To use as a conventional stirrer, the stirring blade and shaft may be used without the outer housing.  Maximum RPM: 11,500. Dimensions: 4-3/8"w x 13"d x 9-1/2" h. Weight: 10 lb (4.5 kg).
