Pasteur pipettes made of borosilicate glass 5.1 are a high-quality alternative to plastic pipettes and pipettes made of soda-lime glass. Applications • Pasteur pipettes are intended for one-time use in microbiological and serological laboratories • Ideal for distributing aliquots quantities of liquid Features & Benefits • Glass pasteur pipettes with short and long drawn fine tip • Made of clear borosilicate glass 5.1 • USP Type I neutral glass • Pipettes conform to ISO 7712 • Inured to rapid temperature changes and chemical attack • Very good chemical resistance to acidic and alkaline solutions • Borosilicate glass 5.1 is more stable than soda-lime glass and therefore ideal for the transfer of hot liquids • Virtually inert borosilicate glass minimizes interaction with the material and reduces the risk of sample contamination • Rubber teat, made from natural rubber, can be ordered separately
