Clarity
Made from an ultra-clear non-cytotoxic medical grade resin that allows you see sample volume and color easily. These tubes feature highly visible printed graduations for easy filling and sample preparation.

Durability
Engineered with thick, durable walls for ultra-high-speed centrifugation. SuperClear® tubes consistently out-perform other brands.

Reliability
Our patented, extra-large writing panel is the largest on the market and transparent to easily view your sample through your label. This writing panel is also smear-resistant for permanent coding and won’t wear off when inserting and removing your tube from the centrifuge rotor.

Security
Leak resistant SuperClear® 15 mL and 50 mL flat caps feature a molded-in sealing ring that keeps your closed tubes completely secure. These caps are ideal for vortexing chemicals and long rocker incubations.

Sustainability
Designed for maximum product recyclability and manufactured in a solar powered facility with unique waste-free molding machines. Tube graphics and graduations are printed with UV cured inks which significantly reduces the emissions of harmful volatile organic compounds (VOCs). Offered in reusable and recyclable racks.
