$250.00
In stockOhaus 31013397 is a swing-out centrifuge rotor with four 10 mL positions, listed within the Frontier 5000 rotor series. It is the smallest swing-out rotor in this catalogue and the only one at tube scale, giving a flat pellet base for small-volume separations. Maximum speed and RCF are not stated in the documentation held for this listing.

Description
Ohaus part number 31013397 is a swing-out rotor with four 10 mL positions. Ohaus lists it within the Frontier 5000 rotor series.
The other swing-out rotors in this catalogue are large-format: 30553085 at 4 x 750 mL and 83041011 at 4 x 200 mL. 31013397 is the only one at tube scale. The reason to choose swing-out geometry at 10 mL is the same as at bulk scale but sharper: the buckets pivot to horizontal at speed, so the pellet lies flat at the bottom of the tube and the boundary between pellet and supernatant stays perpendicular to the tube axis, which makes small volumes easier to decant without disturbance and easier to read against a graduation.
The documentation held for this listing does not state a maximum speed, maximum RCF, tube geometry, bucket material, or whether buckets and adapters are supplied with the rotor. We will not estimate them. Request the current Ohaus rotor specification for 31013397 and confirm it against your centrifuge’s approved rotor list before purchase.
Frequently asked questions
How many tubes does it hold?+
Four positions at 10 mL, per the Ohaus designation for part 31013397. The documentation we hold does not state the tube geometry the buckets are cut for, so check your tubes against the manufacturer's rotor specification before ordering consumables against it.
Why choose a swing-out rotor at this volume?+
The buckets swing to horizontal under rotation, so the pellet forms flat at the base of the tube rather than against its wall. At small volumes that makes the supernatant easier to draw off without disturbing the pellet, and any layer boundary easier to read against the tube's own graduations.
Are the buckets included?+
Not documented on this listing. Swing-out rotors are often supplied as a rotor body with buckets and adapters as separate part numbers, so confirm the packing list against the Ohaus specification for 31013397 before raising a purchase order.
Which centrifuges does it fit?+
Ohaus catalogues 31013397 within the Frontier 5000 rotor series. Confirm the part number against your centrifuge model's approved rotor list before ordering.
What are the maximum speed and RCF?+
Not stated in the documentation we hold. Request the current Ohaus specification for 31013397. Note that swing-out rotors are normally rated below fixed-angle rotors of comparable scale, so the rotor's own rating rather than the centrifuge's headline figure is the one that governs.
