Rotors for Centrifuges
Spin up volumes up to 50 mL
Eppendorf North America Inc, Hauppauge, NY, introduces two new rotors for centrifuges 5804 R and 5810 R. The new 6×50-mL fixed-angle rotor (FA-45-6-30) is now available for use in both the 5804 R and the 5810 R. This rotor can spin up volumes up to 50 mL with max speeds ranging from 16,639 x g in the 5804, 5804 R, and 5810, to 20,130 x g in the 5810 R series. This rotor also includes Eppendorf’s aerosol-tight QuickLock™ lid technology, which requires only a quarter turn. A new aerosol-tight deepwell plate, swing-bucket rotor (A-2-DWP-AT), is also available for use in centrifuges 5810 and refrigerated 5810 R. It contains two large buckets with easy-to-use, aerosol-tight caps, which are able to spin up to five microtiter plates or two deepwell plates (a 60-mm loading height) each up to 3,486 x g.

Tabletop Ultracentrifuge
Entry-level instrument
The Optima MAX-TL tabletop ultracentrifuge, from Beckman Coulter Life Sciences, Brea, Calif, delivers functionality and efficiency within a compact and quiet package. Joining the Optima line of floor and tabletop ultracentrifuges, this entry-level instrument offers context-sensitive on-screen help, and is available in multiple native languages to meet a full range of separation requirements in a user-friendly environment. Users can set multiple programs of up to five steps each using an easily navigated, full-color LCD touchscreen accessible in nine languages. Fully compatible with Beckman Coulter TL labware and fixed-angle, swinging bucket and near-vertical tube rotors, 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 instrument's control speed is 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). The units operate in ambient temperatures from 15° to 35°C.
