$6,021.00
In stockOhaus 30553086 is a fixed-angle centrifuge rotor with four 500 mL positions, carrying the Ohaus ID designation within the Frontier 5000 rotor series. At 2 L per run it is the largest fixed-angle rotor in this catalogue, for bulk pelleting where a wall-formed pellet is acceptable. Maximum speed and RCF are not stated in the documentation held for this listing.

Description
Ohaus part number 30553086 is a fixed-angle rotor with four 500 mL positions, carrying the ID designation in the manufacturer’s part name. Ohaus lists it within the Frontier 5000 rotor series.
Two litres per run makes this the largest fixed-angle rotor in this catalogue. Against the swing-out alternatives at similar scale, 30553085 at 4 x 750 mL and 83041011 at 4 x 200 mL, the fixed-angle geometry gives a shorter sedimentation path and no moving buckets to maintain, at the cost of a pellet that forms against the bottle wall rather than flat at its base. That trade is usually acceptable for harvesting where the supernatant is discarded and unhelpful where the pellet must be decanted cleanly or read at the interface.
The documentation held for this listing does not state a maximum speed, maximum RCF, rotor material, temperature rating, or whether bottles, adapters or a lid are supplied with the rotor, and we will not estimate any of them. Request the current Ohaus rotor specification for 30553086 and confirm it against your centrifuge’s approved rotor list before purchase.
Frequently asked questions
What capacity does this rotor give?+
Four positions at 500 mL, so 2 L per run, per the Ohaus designation for part 30553086. It is the largest fixed-angle rotor listed in this catalogue.
Are bottles or adapters included?+
Not documented on this listing. Large-format rotors are commonly ordered with bottles and adapters as separate part numbers, so confirm the packing list against the Ohaus specification for 30553086 before raising a purchase order.
Should I choose this or the 4 x 750 mL swing-out rotor?+
30553085 is a swing-out rotor at 4 x 750 mL and forms a flat pellet at the base of the vessel; 30553086 is fixed-angle at 4 x 500 mL and forms the pellet against the wall. Choose the swing-out where the pellet must survive decanting or be read at the interface, and the fixed-angle where the supernatant is simply discarded.
What are the maximum speed and RCF?+
Not stated in the documentation we hold, and we will not publish an unsourced rating for a rotor of this size. Request the current Ohaus specification for 30553086, run at the lower of the rotor's and the centrifuge's rated limits, and derate for samples denser than water.
Which centrifuges does it fit?+
Ohaus catalogues 30553086 within the Frontier 5000 rotor series. Large rotors are especially dependent on the individual instrument's drive and chamber, so confirm the part number against your centrifuge's approved rotor list before ordering.
