Frequently Asked Questions
What is the difference between the PP and PS tubes?
Polypropylene (PP) tubes offer broader chemical resistance and tolerate higher temperatures, while polystyrene (PS) tubes are rigid and optically clear for visual inspection. Choose PP for solvent or reagent contact and PS for clarity-dependent reads.
Are these tubes sterile?
No. All options in this family are supplied non-sterile. Validate any required decontamination protocol for your workflow; PP tubes generally tolerate autoclaving better than PS.
Do the instrument-grade tubes fit automated analyzers?
The 110441I and 110410I no-rim 12x75mm tubes are designed for instrument use and fit common analyzer racks accepting that footprint. Confirm dimensions against your platform's tube specification.
How are the tubes packaged and sold?
Prices are per pack as listed. The 5 mL amber comes 1000/bag, 2 bags/carton; the 8 mL no-rim tubes ship 500/bag, 2 bags/unit; the 7 mL PP ships bulk at 3000/case. Instrument tubes ship in their stated unit.
