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 min⁻¹ and a viscosity of up to 500 mPa·s. By connecting additional TWISTER stirring units (available as accessories, IKAA20112621), TWISTER can be expanded to a multi-position magnetic stirrer with up to 30 stirring positions. The stirring positions can be controlled either separately or simultaneously (leader-follower principle).

• Touch operation
• Powerful mixing, ideal for mixing small quantities in small vessels
• Automatic beaker detection
• Torque trend indicator
• Rotation direction reversal
• Individual control of plates, assign a different speed or stirring direction to each stirring position

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

TWISTER enables a new way of interaction between user and laboratory instrument. All information is intuitively conveyed via the intuitive and chemically resistant 360° LED glass display, without an 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 by placing or touching the beaker thanks to integrated beaker recognition. The reverse function changes the direction of rotation at definable time intervals. This leads to a significant improvement of mixing results, 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. The compact and innovative design is robust and safe. It is particularly suitable for use in laboratories with limited space.
