What does the term 2DMix-Control technology describe/stand for?
2DMix-Control technology describes the ability of the MixMate, ThermoMixer C and ThermoMixers F to mix small sample volumes in various plate and tube formats quickly and in a controlled manner. To achieve this, the interplay of all crucial factors for efficient and controlled mixing, have been optimized. And these are:
- Generation of sufficient mixing energy: due to an orbital mixing movement at a high mixing speed and a relatively large mixing radius (1.5 mm) the devices generate enough mixing energy (analogous to g-force in centrifuges) to mix even the smallest volumes efficiently.
- Minimized loss of mixing energy: special attention was paid to reducing inherent vibration. Smooth operation combined with reliable stability ensures that all the mixing energy is available for mixing and not wasted through transmission of vibrations to the device or its surroundings.
- Controlled transmission of energy from the device to the sample: Minimizing vertical movements enable a plane, 2-dimensional (2D) mixing stroke. This, in conjunction with the reliable plate and tube holders and SmartBlocks, prevents uncontrolled chaotic movements and allows all formats to be held securely, even at high mixing frequencies.
What types of applications can be carried out with Eppendorf Tubes® 5.0 mL?
