A case is 500 tubes in 20 sealed bags of 25, and it is the wider-mouth sibling of the 15 mL sterile centrifuge tubes, 500 per case — same screw cap, same resin, different working volume. Labs that run both keep one case of each within reach of the bench.
What does one 50 mL sterile tube cost when the case is $89.99?
The case is $89.99 for 500 tubes, which puts a tube at about 18 cents — 89.99 divided by 500, rounded to the nearest cent. That per-tube figure is the one to carry into a cost-per-sample sheet, because a bench does not consume cases, it consumes tubes. One bag holds 25, so a single bag covers a morning of processing and the rest of the case stays sealed. Both numbers above come from this listing: the case price is the current variant price, and the per-tube figure is arithmetic on it rather than a second price list.

Which sample volumes belong in a 50 mL tube rather than a 15 mL one?
Reach for the 50 mL when the volume itself is the point: pooled urine collections, larger aspirates sent whole to the bench, tissue transport fluid, and any prep where a 15 mL tube would be filled past the point where you can still mix or decant without touching the cap thread. Keep 15 mL for routine serum and plasma work, small aliquots and short spins, and you spend less per test. The two sizes share a cap design, so racks, labels and centrifuge carriers do not need a second protocol.
How do you keep the remaining bags sterile once a case is opened?
Open one bag, not the case. Take the bag to the bench, take out what the run needs, and close the bag again the same shift — a bag left open on a bench collects aerosol and dust that the tube inside was manufactured to avoid. 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. Anything that has left the bag and touched a bench should be treated as non-sterile and kept for non-critical work.
Sample containers for the same run sit on the clinic supply planner, printable bench records are on the compliance log centre, and institutional volumes go through wholesale ordering. Protocol questions about your own bench can go to our compliance desk.
