Plan how many samples a centrifuge can process in a run and across a working session. Enter rotor positions, required balance positions, sample volume, tube working volume, run-cycle time, and available time. The calculator reports usable samples per run, total session capacity, number of runs, and processed sample volume.
The main result is the maximum number of sample tubes processed per run under the entered balancing reservation.
Always follow the rotor and centrifuge manufacturer's loading, pairing, mass-balance, tube, speed, and inspection requirements.
A 24-position rotor with no reserved positions processes 24 samples per run. With a 20-minute cycle and 120 minutes available, 6 runs process 144 samples or 216 mL at 1.5 mL each.
No. It estimates capacity only; use the manufacturer-approved symmetric loading pattern for the specific rotor.
Balance tubes occupy physical rotor positions even though they do not contain samples.
Yes. Treat each aliquot tube as one sample position or adjust the sample count outside the calculator.
Include loading, acceleration, spin, deceleration, unloading, and routine turnaround.
No. Only complete runs that fit within the available time are counted.
