Choose the right rotor for your Savant SpeedVac

On a Savant SpeedVac vacuum concentrator the rotor determines what you can dry down. The rotor type sets which tube, vial or microplate format fits and how many samples you process per run. The wrong rotor means your tubes will not fit or that you dry far fewer samples at once than you could. So choose first on the basis of your tube format and sample count, and take the solvents you use into account. This category holds every rotor and rotor block for the Savant SpeedVac, so you can match your concentrator exactly to your workflow.

Rotor types for the Savant SpeedVac

• Fixed-angle aluminium rotors (RF series): robust rotors such as the RF32, RF52 and RF108 for microcentrifuge tubes and standard tubes. Aluminium conducts heat well and delivers fast, even drying across a large number of positions.
• Hexagonal microcentrifuge rotor (RF132): designed for microcentrifuge tubes, with a hexagonal layout that holds many tubes together compactly.
• Microplate rotor (RFMT4): for drying down microplates and deepwell plates, ideal for high-throughput and automated workflows.
• Open rotors (RH series): models such as the RH32-13 and RH200-12 hold large numbers of tubes in an open layout, useful when you want to dry many samples of the same format at once.
• Shallow-well plate rotor (RHSW6MP): for shallow-well plates and plate formats where you dry down several plates per run.
• Rotor blocks (RB and RBA): interchangeable blocks that hold tubes and vials in a microplate footprint. The polypropylene RB blocks and aluminium RBA blocks let you dry down changing formats and lift them in and out of the concentrator in one go.

Difference between fixed-angle and open rotors

A fixed-angle rotor holds the tubes at a set angle and is usually made of aluminium, which distributes heat well and speeds up drying. Open rotors are designed to hold a large number of tubes and are the logical choice when throughput matters more than speed per sample. For microcentrifuge tubes you often pick a fixed-angle or hexagonal rotor; if you need to dry hundreds of tubes per run, an open rotor from the RH series offers the most capacity.

Rotor blocks: polypropylene (RB) and aluminium (RBA)

Rotor blocks are separate blocks that hold different tubes or vials in a fixed microplate footprint. This lets you lift a complete set of samples in and out of the Savant SpeedVac in one go, which is handy for changing formats or automated work. The polypropylene RB blocks are lighter and cost-effective for general use. The aluminium RBA blocks offer better chemical resistance to aggressive solvents and dry faster and more evenly, because aluminium conducts heat better. If you work with strong solvents or want the shortest drying time, choose the aluminium version.

Buying advice

First decide which tube, vial or plate format you dry down most and how many samples you want to process per run. For microcentrifuge tubes choose a fixed-angle RF or hexagonal RF132 rotor, for large numbers of tubes an open rotor from the RH series, and for plates the RFMT4 or RHSW6MP. If you want to switch flexibly between formats, rotor blocks are the smartest choice: pick polypropylene (RB) for general use or aluminium (RBA) for better chemical resistance and fast drying. Some rotors and blocks can be ordered directly with a price, while others we supply on request. If you are unsure which rotor fits your concentrator, our specialists are happy to advise.
