McKesson Glass Test Tubes, measuring 12 mm in outer diameter and 75 mm in length, are versatile laboratory essentials designed to support various experimental and analytical procedures. Each tube has a capacity of 5 mL and features a plain, colorless design for easy identification. The transparency of the glass allows for clear visibility of the contents, while the round bottom provides stability during handling and storage. Non-sterile for general laboratory use, these test tubes are commonly used in experiments, sample preparation and storage, culture incubation, centrifugation, and chemical reactions. Packaged in quantities of 250, these test tubes are crafted from durable and high-quality glass, ensuring their reliability and longevity. However, as they are not sterile, proper cleaning and sterilization are necessary before use to maintain laboratory standards and prevent contamination.
