Labcon's 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. Samples of proteins, other biological molecules, and cell cultures are commonly shipped and stored on dry ice, putting them at risk of acidification by up to 2.5 pH units.
In standard centrifuge tubes, CO2 vapor from dry ice enters the tube headspace and causes a significant drop in the pH of the sample. Even in short term storage conditions, samples may become acidified. This acidification can affect the integrity and reproducibility of samples, and may result in a loss of protein activity. 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. Features: Airtight, leak-resistant caps prohibit CO2 from entering the tube’s headspace
ProtectR tubes are ideal vessel for primary & secondary containment when shipping on dry ice.
