TWISTER is a universal and compact mixing device with magnetic drive. In the default version, TWISTER is a powerful single-position magnetic stirrer for mixing up to 5 litres at a maximum speed of 3000 rpm and a viscosity of up to 500 mPas.

By connecting additional TWISTER stirring units, TWISTER can be expanded to a multi-position magnetic stirrer with up to 30 stirring positions (depending on the number of devices, a different power supply may have to be used - the included power supply is designed to power up to two devices). The stirring positions can be controlled either separately or simultaneously (leader-follower principle).

With the multi-position stirring attachment (STI3490), the drive is transformed into a magnetic stirrer with 9 stirring positions for efficient mixing of sample vessels with small volumes (8 - 60mL). The shaker attachment (STI3496) transforms the universal magnetic drive into a vortex or orbital shaker.

TWISTER enables a new way of interaction between user and laboratory instrument. Via the intuitive and chemically resistant 360° LED glass display, all information is intuitively conveyed without any alpha-numeric display. During operation, either the speed or the power required for stirring can be displayed. For example, viscosity changes can be observed and displayed as a percentage.

Mixing can be started by pressing a button as well as (thanks to integrated beaker recognition) by placing or touching the beaker.

The reverse function changes the direction of rotation at definable time intervals. This leads to a significant improvement of the mixing result, especially with samples that are difficult to mix.

The high protection class IP 66 allows operation under harsh conditions. TWISTER can thus be cleaned under the tap, for example, or operated in an incubator at temperatures up to 40°C.

• Each set contains TWISTER mixer (1, 2, 3 or 4), power supply and mixing stirring bars
• Add-on unit is supplied without power supply and without accessories
• Please check whether the power of your currently used power supply is sufficient to supply the planned number of TWISTER devices:
• Up to 2 devices: power supply from TWISTER SET 1 & 2
• 2 to 4 devices: TW. PWR.1 or power supply from TWISTER SET 3 & 4
• 4 to 30 devices: TW.PWR.2
