Ohaus 30472304 24 x Capillaries Hematocrit Rotor V2
$888.00
In stockOhaus 30472304 is a hematocrit rotor with 24 capillary positions, carrying the V2 designation within the Frontier 5000 rotor series. Hematocrit rotors spin sealed microhaematocrit capillaries so packed cell volume can be read off against a scale, a dedicated format rather than a tube rotor with adapters. Maximum speed, RCF and run time are not stated in the documentation held for this listing.

Description
Ohaus part number 30472304 is a hematocrit rotor with 24 capillary positions, carrying the V2 designation in the manufacturer’s part name. Ohaus lists it within the Frontier 5000 rotor series.
A hematocrit rotor is a purpose-built format rather than a general tube rotor: microhaematocrit capillaries are held radially in shallow channels under a retaining plate, and the packed cell volume is read from the spun capillary against a reading scale. Capillary work is unusual among centrifuge applications in that the result depends on the run being performed exactly as the method specifies, so the rotor’s rated speed and the method’s stated spin time both matter.
Precisely because the method is procedure-bound, we will not publish figures we cannot source. The documentation held for this listing does not state a maximum speed, RCF, recommended spin time, capillary dimension or whether a reading scale or retaining plate is supplied. Request the current Ohaus rotor specification for 30472304. Note also that 83041007 appears in this catalogue with an identical description under a different part number.
Frequently asked questions
What does this rotor hold?+
Twenty-four capillary positions, per the Ohaus designation for part 30472304. The documentation we hold does not state the capillary length or bore the rotor is cut for, so check your capillaries against the manufacturer's rotor specification before ordering consumables against it.
What is a hematocrit rotor used for?+
Microhaematocrit determination: sealed capillaries of whole blood are spun until the cells pack, and the packed cell volume is read as a fraction of the total column. It is a dedicated rotor format, not a tube rotor used with capillary adapters.
What speed and spin time should be used?+
Not stated in the documentation we hold, and this is not a figure to estimate. Microhaematocrit results are only valid when the spin conditions match the method being followed, so take the speed and time from your own validated method and confirm the rotor's rated limit from the current Ohaus specification for 30472304.
How does this differ from 83041007?+
Both are listed in this catalogue as 24 x capillaries hematocrit rotors with the V2 designation, under different Ohaus part numbers. We hold no documentation explaining the difference, so confirm which part number your centrifuge is approved to run and quote it in full.
Is a reading scale or retaining plate included?+
Not documented on this listing. The rotor is supplied under Ohaus part number 30472304; confirm the packing list against the manufacturer's specification before ordering if a retaining plate, lid or reading device is required.
Which centrifuges does it fit?+
Ohaus catalogues 30472304 within the Frontier 5000 rotor series. Confirm the part number against your centrifuge model's approved rotor list before ordering.
