Description
Ohaus part number 83041010 is a fixed-angle rotor with 12 positions for 5 mL FA tubes, carrying the ID and Sealable designations in the manufacturer’s part name. Ohaus lists it within the Frontier 5000 rotor series.
Five millilitres is an awkward volume to cover: too large to run comfortably in a 1.5/2.0 mL microtube rotor and wasteful in a 15 mL one, where a part-filled tube sediments over a longer path than it needs to. 83041010 is the only rotor in this catalogue cut for that format, and it is one of the designated sealable parts here alongside 30314836 and 83041006 in microtube formats.
The documentation held for this listing does not define the ID or Sealable designations, state whether the sealing lid is supplied, or give a maximum speed, RCF, containment rating, material or temperature rating. We will not publish those unsourced. Request the current Ohaus rotor specification for 83041010 and confirm the packing list and your centrifuge’s approved rotor list before purchase.
Frequently asked questions
How many tubes does it hold?+
Twelve positions for 5 mL FA tubes, per the Ohaus designation for part 83041010. Check your tube's outside diameter and overall length against the manufacturer's rotor specification, since 5 mL tubes vary considerably in profile between suppliers.
Is the sealing lid included?+
Not documented on this listing. The part name carries Ohaus's Sealable designation, but whether the lid and seal ship with the rotor or are ordered as separate part numbers is not stated in the documentation we hold. Confirm the packing list against the Ohaus specification for 83041010.
Why use a 5 mL rotor rather than a 15 mL one?+
A tube run well below its nominal volume sediments over a longer path than necessary and leaves more headspace to balance around. Where the sample is genuinely 5 mL, a rotor cut for that format keeps the path short and the load predictable. This is the only 5 mL rotor listed in this catalogue.
Which centrifuges does it fit?+
Ohaus catalogues 83041010 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Not stated in the documentation we hold, and we do not publish unsourced rotor ratings. Request the current Ohaus specification for 83041010 and run at the lower of the rotor's and the centrifuge's rated limits.
