Economical and highly accurate, LifeLINE™ Disposable Glass Serological Pipets are calibrated to deliver with tolerances of +/- 0.2% to assure the most reliable and reproducible results. Fully annealed inner and outer surfaces provides extra strength to resist breakage and assure clean and reproducible performances with less possibility of contamination and variation in drainage. Their long and tapered, regular or wide, fully annealed tip is designed for smooth flow and easy access. Highly durable and chemically inert, these borosilicate LifeLINE™ glass pipets are characterized with superior clarity and minimal pH shift. Each pipet feature bold, easy to read, ascending and descending graduations. The negative graduations provide the user with additional versatility. Each size is identified with color-coded bands. Individually wrapped pipets are further identified in color coded single-packs
