Falcon® 352096 | 15mL High-Clarity Polypropylene Conical Centrifuge Tube with Dome Seal Screw Cap, Sterile — 50/Bag, 500/Case

The Falcon® 352096 is a 15mL high-clarity polypropylene conical centrifuge tube with dome seal screw cap — Falcon® 15mL high-clarity polypropylene (PP) conical centrifuge tubes have a 12,000 RCF rating. The tubes come with polyethylene dome seal screw caps. The sterile tubes are packaged 50 per bag and 500 per case. RNase/DNase-free. Approximate dimensions: 17mm O.D.; 120mm length. Sterilized by gamma irradiation, noncytotoxic and nonpyrogenic. Dark blue printed graduations and white writing patch. Meet bioanalytical-grade requirements and provide unsurpassed performance in critical research applications. The tubes feature dark blue printed graduations in 0.5mL increments visible with clear or turbid samples, and a solvent-resistant white writing patch. 50 tubes per bag, 500 tubes per case.

High-Clarity Polypropylene — Exceptional Optical Clarity with Full Chemical Resistance The defining material characteristic of the 352096 is its high-clarity polypropylene construction — a premium resin formulation that delivers the optical clarity approaching that of polystyrene while maintaining all the chemical resistance, temperature stability, and mechanical strength advantages of polypropylene. Standard polypropylene centrifuge tubes sacrifice clarity for chemical resistance — the high-clarity PP of the 352096 eliminates this tradeoff, providing clear visualization of sample pellets, gradient bands, and liquid interfaces without compromising the solvent resistance, autoclavability, and wide temperature range that make polypropylene the material of choice for critical centrifuge tube applications.

12,000 RCF Rating — High-Speed Centrifugation Performance Falcon® 15mL high-clarity polypropylene (PP) conical centrifuge tubes have a 12,000 RCF rating. At 12,000 RCF, the 352096 is rated significantly higher than standard polystyrene 15mL conical tubes (typically 1,500–3,000 RCF) — making it suitable for the demanding high-speed centrifugation protocols used in nucleic acid isolation, protein precipitation, density gradient ultracentrifugation preparation, and other molecular biology workflows requiring speeds well above what polystyrene tubes can safely accommodate. The tube walls are engineered to perform under high-stress situations, making these tubes the workhorse of the life sciences lab.

Dome Seal Screw Cap — Positive Seal Over Full Circumference Polyethylene dome-seal screw cap offers positive seal over full circumference. The dome seal design of the 352096 cap creates a positive mechanical seal around the complete circumference of the tube opening — eliminating the leak pathways at the cap-to-tube interface that can occur with standard flat-seal screw caps, particularly during high-speed centrifugation where internal pressure and mechanical forces stress the cap seal. Unique double threaded cap design reducing cross threading and leakage. The double-threaded cap engagement reduces the risk of cross-threading — a common problem with single-thread caps in high-throughput labs where tubes are capped and uncapped rapidly — and further reduces leakage risk during centrifugation and storage.

Dark Blue Printed Graduations in 0.5mL Increments — Visible with Clear or Turbid Samples Dark blue graduations in 0.5mL increments are visible with clear or turbid samples. The dark blue graduation printing of the 352096 provides high-contrast volume markings that remain readable against both clear samples and turbid or colored biological samples — unlike light-colored graduation marks that are difficult to read when the tube contains opaque pellets, colored media, or biological fluid. The 0.5mL graduation increment provides sufficient precision for accurate volume measurement across the full 15mL capacity.

White Writing Patch — Solvent-Resistant, Permanent Marker Compatible Solvent-resistant white writing area. The large white writing patch on the 352096 provides a dedicated labeling surface for permanent marker identification of sample contents, concentration, date, lot number, and operator initials — and the solvent-resistant surface ensures that labels remain legible during centrifugation, storage in organic solvents, and repeated freeze-thaw cycles that would cause standard labeling patches to smear or degrade.

Bioanalytical-Grade Requirements — Unsurpassed Performance in Critical Applications Meet bioanalytical-grade requirements and provide unsurpassed performance in critical research applications. The 352096 meets bioanalytical-grade specifications — the performance standard required for regulated analytical workflows including pharmacokinetic sample preparation, clinical sample processing, biomarker quantification, and any application where tube-related interference, extractables, or material failure could compromise analytical results.

Ideal for Cell Centrifugation, Pelleting, and Density Gradients Ideal for cell centrifugation; pelleting; separation by density gradients. The conical bottom of the 352096 concentrates cell pellets and precipitates to the lowest point of the tube — minimizing pellet area for efficient resuspension and maximizing pellet visibility through the high-clarity PP wall. The 15mL conical format is also the standard tube for density gradient separations where sample is layered over gradient media and centrifuged to separate components by density.

Wide Temperature Stability — From Freezer to Autoclave High strength with wide temperature stability. The high-clarity polypropylene construction of the 352096 maintains its mechanical properties and dimensional stability across a wide temperature range — from ultra-low temperature storage in -80°C freezers through room temperature processing, 37°C incubation, and autoclave sterilization at 121°C. A single tube format handles every temperature stage of the most demanding workflows.

Sterile — Gamma Irradiation, Noncytotoxic, Nonpyrogenic Sterilized by gamma irradiation, noncytotoxic and nonpyrogenic. Every 352096 is sterile by gamma irradiation and tested for noncytotoxicity and nonpyrogenicity — qualifying it for cell culture, primary cell processing, clinical sample handling, and any application where tube material contamination or endotoxin content could affect biological results.
