Centrifuge Tubes (5 mL and 11 mL Round-Bottom Configurations)
Description
Centrifuge Tubes (5 mL / 11 mL round-bottom) are premium, high-clarity laboratory tubes engineered specifically for delicate cell handling, washing, and separation protocols. Featuring a completely rounded bottom profile and threaded necks for secure closures, these transparent tubes ensure optimal sample recovery and clear visualization during low-volume andrology, IVF, and general clinical laboratory processing.Our medical-grade Centrifuge Tubes (5 mL / 11 mL round-bottom) provide the perfect balance of optical clarity and structural reliability for modern laboratories and specialized fertility clinics. This product family offers two distinct volume capacities tailored to match specific sample sizes and processing requirements. Unlike standard conical options, the smooth, round-bottom architecture is explicitly designed to support uniform pelleting and gentle cell resuspension without risking structural damage to fragile cellular samples during handling.
The two options are optimized for specific lab workflows:
5 mL Configuration: A sleeker, narrower tube option equipped with highly accurate, finely spaced vertical graduation markings. The exterior wall features a clear breakdown scale lining up to 12mL, complete with a prominent 5 mL marker to guarantee precise fluid measurements during small-volume washes or micro-pelleting.
11 mL Configuration: A wider, high-capacity tube designed for larger fluid fractions or multi-step density gradient preparations. It features structured graduation tick marks on the side alongside a bold 11 mL volume callout text label for rapid reading at a glance.
Both variants are manufactured from transparent, ultra-pure polymers that allow clean optical monitoring of samples and fluid interface lines. Each tube features a sturdy threaded neck layout designed to easily fit a leak-proof screw cap closure, preventing cross-contamination and aerosol formation during high-speed rotations.
