Ohaus 30314832 30 x 15ml RB/FA Fixed Angle Rotor ID
$2,076.00
In stockOhaus 30314832 is a fixed-angle centrifuge rotor with 30 positions for 15 mL RB/FA tubes, catalogued by Ohaus within its Frontier 5000 rotor series. It is the highest-capacity 15 mL fixed-angle rotor in this catalogue; compare 30314834 (12 x 15 mL) and 30472305 (8 x 15 mL) if a smaller footprint suits your throughput. Maximum speed and RCF are not stated in the documentation held for this listing, so request the current Ohaus rotor specification for 30314832 before writing it into a protocol.

Description
Ohaus part number 30314832 is a fixed-angle rotor carrying 30 positions for 15 mL RB/FA tubes. Ohaus lists it within the Frontier 5000 rotor series. In a fixed-angle rotor the tubes are held at a constant angle throughout the run, which shortens the sedimentation path and drives the pellet against the tube wall rather than flat across its base.
At 30 places this is the largest 15 mL fixed-angle rotor in this catalogue. Where a run does not justify a full load, 30314834 carries 12 x 15 mL and 30472305 carries 8 x 15 mL in the same tube format. Rotors are balanced by opposing pairs, so the practical capacity of any of them is an even, symmetrically loaded number of tubes rather than the nominal position count.
We publish only what we can source. Ohaus does not state a maximum speed, maximum RCF, rotor material, temperature rating or autoclave compatibility in the documentation held for this listing, and we will not estimate those figures. Request the current manufacturer rotor specification for 30314832 and check it against your centrifuge’s approved rotor list before purchase.
Frequently asked questions
How many tubes does this rotor hold?+
Thirty positions for 15 mL RB/FA tubes, per the Ohaus designation for part 30314832. Tube fit depends on the exact outside diameter and length of the consumable you use, so check your tube geometry against the manufacturer's rotor specification before committing to a bulk consumable order.
Which centrifuges does this rotor fit?+
Ohaus catalogues 30314832 within the Frontier 5000 rotor series. Fitment is specific to the centrifuge model and drive, and membership of a rotor series does not by itself mean a rotor is approved for every instrument in that series. Confirm the part number against your centrifuge's approved rotor list before ordering.
What are the maximum speed and RCF?+
We do not hold manufacturer documentation stating a maximum speed or RCF for this rotor, and we will not publish figures we cannot source. Request the current Ohaus specification for 30314832. As general practice a rotor is run at the lower of the rotor's and the centrifuge's rated limits, and derated for samples denser than water.
What does the RB/FA designation mean?+
RB/FA is the tube-format designation Ohaus uses in the part name. We hold no manufacturer documentation defining it for this part, so confirm the intended tube type against the Ohaus rotor specification rather than inferring it from the abbreviation.
What is supplied with the rotor?+
This listing covers the rotor as supplied under Ohaus part number 30314832. Lids, adapters, tubes and other accessories are not documented as included, so confirm the packing list before ordering if any of those are required for your application.
How should this be referenced on a purchase order?+
Quote manufacturer part number 30314832 together with the brand (Ohaus) and the SKU shown on this page. Several rotors in this range share the same tube capacity and differ only by part number and version, so the part number is the only unambiguous identifier.
