Fixed and Variable Speed Rotators. I don’t know about you, but they kind of remind me of a Ferris Wheel. All kidding aside, unlike a centrifuge, rotators, which are also known as Tissue Culture Rotators, provide an ideal and effective means for the gentle mixing of tissue culture specimens and for keeping biological samples in suspension. An example being blood and the aerating of cultures. The head uses the principal of Friction Drive and will accommodate thirty-one 10–18mm dia. tubes or sixteen 20–30mm dia. tubes. These rotators can be used in incubators up to 60°C and in cold rooms with temperatures dropping down to 4°C. The angle of rotation is fully adjustable and has a scale to measure and reproduce the mixing angle, from horizontal for minimal mixing to vertical for full end-over-end mixing.
The speeds range for the fixed rotator running at 20 rpm, to the variable models that have an adjustable speed between 2 and 40 rpm.
Digital timers and speed display allow procedures to be accurately repeated for optimal results. Spring clips attach easily to the rotators head to hold test tubes in place.
Tube rotators are typically utilized by biochemistry, molecular biology, clinical testing and histochemistry groups. Uses include:
• DNA Purification
• Sample mixing / re-suspension
• Protein Binding
