The Cole Parmer Stuart Roller Mixers provide a gentle, but highly efficient, rocking and rolling action. The six rollers design has a small space saving footprint, while the nine roller unit has a higher capacity

Control is through a simple on/off switch and the unit will run continuously at the fixed speed of 33rpm

Recommended for mixing blood samples, viscous substances and liquid-solid suspensions where minimum aeration is required. Units can be used in incubators up to 60°C and humidity up to 80%, or in cold rooms down to 4°C.

Both roller mixers are robustly constructed and designed for easy cleaning, having plastic rollers and a drip tray to collect accidental spillages.

Most sizes of tubes, Bijoux, Universals and bottles can be accommodated, up to 100mm diameter. An accessory stacking system SRT/STACK is available where bench space is at premium.

Removable Side Panels: Stuart roller mixers now feature easy to remove side panels. The side panels provide the user with complete peace of mind that their sample will be mixed effectively during continued use. The side panels ensure the sample bottles do not slide off the mixer during use and therefore provide the highest levels of both safety and functionality.

Detachable Roller Tubes: The roller tubes on Stuart roller mixers conveniently detach to accommodate larger vessels and therefore allow the user to mix a wide variety of differently sized tubes and bottles. Stuart roller mixers provide the highest levels of versatility as any of the roller tubes can be removed meaning the user can choose the arrangement depending on their needs.
