Four-place rotor with stainless-steel rotor yoke and removable aluminum swinging buckets for use in Beckman Coulter Avanti™ J-15 Series of benchtop centrifuges.
Buckets are interchangeable with JS-4.750 BioSafe Microplate Carriers 392806 for spinning microtiter plates or microfuge tubes using rack inserts.
- Optional BioCertified Aerosolve® canisters
- Wide list of modular disk adapters
- RCF needed for various applications
The rotor buckets carry adapters that allow centrifugation of a wide range of tube and bottle sizes (from 1.5 mL reaction vials to 750 mL bottles), single- to quad-pack blood bags, and multi-well plates in carriers. The rotor develops centrifugal forces that are suitable for rapidly sedimenting protein precipitates, large particles, cells, and cell debris.
Transparent covers made of a high impact plastic are available for the rotor buckets. Covers have been tested to demonstrate containment of microbiological aerosols under normal conditions when used and maintained as instructed. Each cover requires an O-ring that seats on a ledge inside the bucket.
Multi-well plates are used for many applications, including culturing small populations of cells, immunoassays, and serial dilution of small liquid volumes. Carriages used in the carriers can each hold up to four stacked multi-well plates (not to exceed 55.9 mm (2.2 in.) in depth) or one deep-well or square well plate. Each carrier can also carry a multi-well kit for high-throughput processing (such as DNA or RNA kit).
Rotor JS-4.750 comes with four buckets and rotor JS-4.750µ comes with four microplate carriers. Since both rotor share the same yoke, buckets and/or microplates can be used on either rotor. BioCertified aerosolve canisters can be used in the buckets.
Most SX4750 and SX4750A tube adapters are compatible with the JS-4.750 swinging bucket rotor. Always refer to the rotor manual for the list of compatible tubes, adapters and accessories.
*Up to three Beckman Coulter plates, separated by cap strips, can be run per carrier at maximum multi-well plate speeds. If running four Beckman Coulter plates, cap strips cannot be used due to height limitations; reduce run speed to 2,700 rpm. Observe manufacturer’s run speed and stacking limitations if using other manufacturers’ multi-well plates.
