ProtectR™ Tubes keep your samples safe from pH changes.

Made of durable, high quality materials and fitted with an air-tight cap, ProtectR™ Tubes form a protective barrier impermeable to CO₂ keeping the sample pH stable and preventing acidification.

Labcon ProtectR™ Tube is the only container closure system engineered to be CO₂ resistant and stop costly damage to molecular and cellular solutions when using dry ice.
