Following Rotors: JS-13.1, JA-14, JA-20, JA-25.15, JA-25.50, JLA-10.500, JLA-16.250, JLA-8.1000, F10BCI-6x500y FIBERLite.
High-speed centrifuge is used for sample preliminary purification, which used for large sample volume, and less purity. Select the appropriate rotor and centrifuge tubes, so you can get better experimental results. The load in a laboratory centrifuge must be balanced carefully. This imbalanced force the spindle and may result in damage to the centrifuge or personal injury.
Following Rotors: SW 28 Ti, SW 41 Ti, Type 45 Ti, Type 50.4 Ti, Type 55.2 Ti, NVT™ 65 Rotor Assy, Type 70.1 Ti.
A. Fixed Angle Rotor (designated Type)----are general-purpose rotors that are mainly used for pelleting subcellular particles and in short-column banding of viruses and subcellular organelles.
B. Vertical-Tube rotor (designated V)----are used for pelleting, separation of density and sedimentation coefficient.
C. Swinging-Bucket Rotor (designated SW)----are hold tubes parallel to the axis of rotation, used for isopycnic and, in some cases,, rate zonal separations when run time reduction is important.
D. Near-Vertical Rotor (designated NV)----are designed for gradient centrifugation when there are components in a sample mixture that do not participate in the gradient.
Selection of a rotor depends on a variety of conditions, such as sample volumn, number of sample components to ge separated, particle size, desired run time, desired quality of separation, type of separation, and the centrifuge in use.
The Optima MAX-TL can be used in applications including separation of subcellular particles, viruses and viral particles, rate-zonal separation of proteins in sucrose gradient, separation of lipoproteins, pelleting of RNA through a CsCl gradient, isopycnic separation of plasmid DNA and others. With a maximum speed of 120,000 rpm and maximum rcf of 657,000 x g, the instruments control speed within ±50 rpm of set point. Temperatures can be set from 0° to 40°C in 1°C increments, and controlled within ±2°C of set point (after equilibrium).
