In stockA fixed-angle centrifuge rotor for 6 x 85 mL tubes, supplied as Ohaus part 30314825. The part is catalogued under the Ohaus Frontier 5000 rotor series. We received no Ohaus specification sheet with this listing, so speed, RCF and permitted tube types should be confirmed against the manual for your centrifuge before you order. Ohaus 30314826 shares this capacity and tube format under a different part designation, so check the full part number when ordering.

Description
Ohaus 30314825 is a fixed-angle centrifuge rotor with positions for 6 x 85 mL tubes. It is an accessory for an existing centrifuge, not a complete instrument.
The part is catalogued under the Ohaus Frontier 5000 rotor series.
A fixed-angle rotor holds tubes at a constant angle to the axis of rotation for the whole run. The sedimentation path is shorter than in a swing-out rotor and pellets form against the outer tube wall, which suits pelleting and general sample preparation. A swing-out rotor, by contrast, lets buckets rotate to horizontal so the pellet forms flat at the bottom of the tube, which is usually preferred for density gradients and for anything where a clean, flat interface matters.
Ohaus abbreviates rotor configurations in its own part naming (“ID”, “RB”, “Hi”). We have reproduced those designators exactly as Ohaus publishes them rather than expand them, because no manufacturer datasheet accompanied this listing to confirm what each one denotes.
Specifications confirmed for this listing:
- Manufacturer: Ohaus
- Ohaus part number: 30314825
- Rotor type: Fixed-angle
- Capacity and tube format: 6 x 85 mL tubes
- Ohaus designators in the part name: “ID”, “RB”, “Hi”
- Series: Ohaus Frontier 5000 rotor series
Only the figures above are confirmed. Rotor material, maximum speed, maximum RCF, temperature rating and autoclavability are not stated in the data we hold for this part, and we have not inferred them. If your procurement or quality process needs those values documented, ask us and we will obtain them from Ohaus in writing.
Frequently asked questions
What tube format and capacity does this rotor take?+
Ohaus 30314825 is configured for 6 x 85 mL tubes.
Which centrifuge does this rotor fit?+
It is catalogued under the Ohaus Frontier 5000 rotor series. The series spans several centrifuge models and not every rotor is approved for every one of them, so check this part number against the approved rotor list for your specific Frontier 5000 instrument before ordering.
What is the maximum speed and RCF?+
Not published on this page. Maximum speed and relative centrifugal field are a property of the rotor-and-centrifuge combination, and no Ohaus datasheet accompanied this listing. The rated figures for your instrument are in its Ohaus manual; we can also request them in writing from Ohaus if you need them documented for a validation file.
What do the abbreviations in the part name mean?+
The designators "ID", "RB", "Hi" are Ohaus's own part-naming shorthand. We have reproduced them exactly as Ohaus publishes them rather than expand them, because we hold no manufacturer datasheet for this part that would confirm what each one denotes. Ohaus technical support or your centrifuge manual will give the authoritative definitions.
Is a centrifuge included?+
No. This is a rotor supplied as an accessory for an existing centrifuge. The listing does not include a centrifuge, and the supplier data does not itemise which tubes, adapters, lids or seals are supplied with the rotor - ask us to confirm the pack contents before ordering if that matters to your specification.
How does this differ from Ohaus 30314826?+
The two parts share the same nominal capacity and tube format but carry different Ohaus part designations, which in this catalogue is the only difference we can evidence. We have not been supplied with documentation explaining what separates them, so order by the full part number and ask us to confirm with Ohaus if you need to know which variant your centrifuge is approved for.
