Twenty bags of 25 sit in the case, and the larger sibling in the same family is the 50 mL sterile centrifuge tubes, 500 per case — identical cap thread, identical resin, a different working volume. Most benches end up holding both, because the tube you pick is set by the volume of the sample, not by the rack.
What does one 15 mL tube cost when the case is $59.99?
The case is $59.99 for 500 tubes, so a single tube works out at about 12 cents: 59.99 divided by 500 is 0.11998. The case also breaks into 20 bags of 25, which puts one bag at about $3.00 — 59.99 divided by 20. Bag-level arithmetic is the one that survives contact with a real bench, since nobody opens a case at a time; the bag is the unit you actually consume, and the tube is the unit you put on a cost-per-test line.

When does a 15 mL tube hold the sample, and when do you step up to 50 mL?
Routine serum and plasma work, small aliquots, short spins and anything that will be split into secondary tubes belong in 15 mL: the tube fills to a workable fraction, the pellet forms at the bottom rather than smeared up the wall, and the pipette reaches the liquid without a long reach down. Step up to the 50 mL size when the volume itself is the sample — pooled urine, larger aspirates, tissue transport fluid, a prep that would overfill a smaller tube. Because both sizes share a cap design, the same racks and carriers serve both.
How do you keep the rest of the case sterile after the first bag is opened?
Open the bag, not the case. Carry one bag to the bench, take what the run needs, and close it again in the same shift — a bag left open collects bench aerosol, and the tube inside was manufactured sterile for a reason. Write the open date on the bag, keep the case closed and off the floor, and never tip unused tubes back into a bag they came out of. A tube that has touched a bench and then re-enters the bag is no longer sterile, whatever the label says.
Case and bag quantities for a month of runs can be laid out on the monthly case planner; the sterilization and bench log templates print from the compliance log centre, which also holds the sterilization log generator for the loads these tubes go into. Multi-site or laboratory-volume orders are handled at wholesale ordering, and any question about your own sample-handling protocol can be put in writing to the compliance desk.
