Description
Ohaus part number 30472302 is a fixed-angle rotor with 24 positions for 1.5 mL and 2.0 mL microtubes, carrying the BIOSEALS and V2 designations in the manufacturer’s part name. Ohaus lists it within the Frontier 5000 rotor series.
Twenty-four places is the working middle of the microtube range in this catalogue, sitting between 83041006 at 18 and 30314836 at 30, with 30372717 and 30372718 at 44 for batch work. It divides cleanly into balanced pairs and into the 8- and 12-tube groupings that most manual prep protocols are written around.
BIOSEALS is Ohaus’s own designation within the part name. We hold no manufacturer documentation defining what it covers, and none stating maximum speed, RCF, seal material, containment rating or whether sealing components are supplied with the rotor. Those are safety-relevant claims and we will not infer them. Request the current Ohaus rotor specification for 30472302, and note that 30642371 is listed in this catalogue with an identical description under a different part number.
Frequently asked questions
How many microtubes does it hold?+
Twenty-four positions for 1.5 mL and 2.0 mL microtubes, per the Ohaus designation for part 30472302.
What does the BIOSEALS designation cover?+
BIOSEALS is Ohaus's designation in the part name. We hold no manufacturer documentation defining it, so we will not state what containment or sealing it provides. Any containment claim for a sealed rotor must come from the manufacturer's specification for the exact part number and be assessed against your own biosafety requirements.
How is this different from 30642371?+
Both are listed in this catalogue with the same description: 24 x 1.5/2.0 mL fixed-angle rotor, BIOSEALS, V2. They are distinct Ohaus part numbers and we hold no documentation explaining the difference. Confirm which part number your centrifuge is approved to run and quote it in full on the purchase order.
Which centrifuges does it fit?+
Ohaus catalogues 30472302 within the Frontier 5000 rotor series. Confirm the part number against your instrument's approved rotor list before ordering.
What are the maximum speed and RCF?+
Not stated in the documentation we hold, and we do not publish unsourced rotor ratings. Request the current Ohaus specification for 30472302 and run at the lower of the rotor's and the centrifuge's rated limits.
Are sealing components supplied with the rotor?+
Not documented on this listing. Confirm the packing list against the Ohaus specification for 30472302 before ordering, particularly if the sealing arrangement is part of your containment case for the work.
