Description

Ohaus part number 30314834 is a fixed-angle rotor with 12 positions for 15 mL RB/FA tubes, carrying the ID designation in the manufacturer’s part name. Ohaus lists it within the Frontier 5000 rotor series.

This catalogue carries three fixed-angle rotors in the 15 mL format: 30472305 at 8 places, 30314834 at 12, and 30314832 at 30. Twelve places suits benches running paired samples in sixes without committing rotor mass and load-balancing effort to a rotor sized for batch work. As with any rotor, tubes are loaded in opposing pairs, so usable capacity is an even, symmetrically distributed number rather than the full position count.

Ohaus does not state a maximum speed, maximum RCF, material or temperature rating in the documentation held for this listing, and we will not estimate them. Request the current Ohaus rotor specification for 30314834 and confirm it against your centrifuge’s approved rotor list before purchase.

Frequently asked questions

How many 15 mL tubes does it hold?+

Twelve positions for 15 mL RB/FA tubes, per the Ohaus designation for part 30314834. Check your tube's outside diameter and length against the manufacturer's rotor specification, since nominal volume alone does not establish fit.

How does it compare with 30314832 and 30472305?+

All three are fixed-angle rotors in the 15 mL format listed in this catalogue: 30472305 holds 8, 30314834 holds 12, and 30314832 holds 30. They are distinct part numbers with distinct approvals, so select by the part number your centrifuge supports rather than by capacity alone.

Which centrifuges does it fit?+

Ohaus catalogues 30314834 within the Frontier 5000 rotor series. Confirm the part number against your instrument's approved rotor list before ordering; series membership does not by itself establish compatibility with a specific machine.

What are the maximum speed and RCF?+

Not stated in the documentation we hold for this part, and we will not publish an unsourced rotor rating. Request the current Ohaus specification for 30314834. Run at the lower of the rotor's and the centrifuge's rated limits, derated for dense samples.

What is included?+

The rotor as supplied under Ohaus part number 30314834. Lids, adapters and tubes are not documented as included on this listing; confirm the packing list before ordering if your application requires them.
