Troy Biologicals Lab Tubes for Centrifugation & Sample Handling

Lab managers and technicians stocking a bench count on Troy Biologicals for the everyday plasticware that keeps a workflow moving — sterile centrifuge and test tubes engineered to the tolerances clinical and research protocols demand. This collection focuses on Falcon-brand polystyrene tubes, the kind of consumable you order by the case and never want to second-guess.

The two workhorses here answer different needs. The Falcon Centrifuge Tubes (352095) are 15 mL, 17 x 120 mm, with a screw cap and conical bottom — built for spins rated to 1,800xG, so they hold up during separation and let you recover pellets cleanly from the tapered base. When you need a secure seal for storage or transport, the threaded cap earns its keep. The Falcon Test Tubes (352057) are 14 mL, 17 x 100 mm, round-bottom with a snap cap, rated to 1,400xG — the go-to for routine sample collection, mixing, and lower-speed processing where a quick-on, quick-off closure saves time.

All tubes are supplied sterile and made from optically clear polystyrene, so you can read fill lines and inspect samples without cracking a cap. They're plain (unprinted) and uncoded, giving you a clean surface for your own labeling scheme. If you're deciding between the two, it comes down to geometry and speed: conical screw-cap for high-speed separation and pellet recovery, round-bottom snap-cap for general handling. Many labs stock both.

Buyers typically ask about g-force ratings, sterility, and cap type before ordering — the specs above cover the essentials, and both meet the standards expected in clinical and research settings. For more products from this supplier, browse the full Troy Healthcare LLC collection.
