Thrust washers for high precision and maintenance-free use in thermal shakers

• What was needed: iglidur® G thrust washers
• Requirements: No vibrations and imbalances should occur when the tubes with laboratory samples are accelerated at up to 3,000 revolutions per minute and heated up to 99 °C.
• Industry: Medical technology
• Success for the customer: The integrated 3-dimensionally controlled guidance of the shaking movement enables planar and vibration-free working for the first time, even at very high shaking frequencies of up to 3000 rpm, and delivers excellent results in temperature-controlled mixing.

Due to their design, the commonly used guidance of the reaction vessels on elastic elements allows uncontrolled movements, which are contrary to the requirement for reproducible processing and generate massive unwanted vibrations. Furthermore, most of the existing devices are very unwieldy due to their installation size and mass and have a negative impact on their surroundings due to uncompensated imbalances. A small and lightweight laboratory device suitable for everyday use is desirable, which mixes the samples to be analysed in sample tubes at up to 3000 rpm without vibration and actively maintains the temperature from room temperature to 99 °C.

The implementation of orbital and planar guided mixing movements using thrust discs made of the material iglidur® G leads to a significantly more robust, precise and low-maintenance technology than that of the classic thermal shakers.
The integrated 3-dimensionally controlled guidance of the shaking movement enables planar and vibration-free working for the first time, even at very high shaking frequencies of up to 3000 rpm, and delivers excellent results in temperature-controlled mixing. The precisely set mixing orbital diameter of 3.0 mm always remains constant. Unwanted lid wetting or spilling of the samples are therefore a thing of the past. This eliminates the need for time-consuming centrifugation steps after mixing.
