Butterfield's Phosphate Buffer Glass Tubes

Supplied in optically clear glass tubes manufactured from clarified glass for excellent sample visibility, these ready-to-use dilution blanks are available in 9 mL and 9.9 mL fill volumes in two tube sizes (16 mm x 125 mm or 20 mm x 125 mm) to accommodate diverse sample dilution requirements. The flat-bottom tube design contributes to stability when set on end during sample preparation, while leak-proof caps provide security during handling and transportation, ensuring dilution blank integrity from preparation through laboratory processing. The pre-filled format eliminates the time-consuming process of preparing individual dilution blanks while ensuring consistent pH and volume accuracy across all testing operations.
