Hach Powder Pillows and Singlet™ pH Buffers

pH Buffer standard solutions for laboratory and field analysis.

pH Buffer Powder Pillows for pH electrode calibration. Each powder pillow prepares 50 mL of fresh buffer solution. Color-coded for easy identification. Powder pillows also assure freshness and eliminate the possibility of contamination. Simply open the pillow and add the contents to 50 mL of deionized or demineralized water.

New one-use-only Singlets are the ultimate in accuracy. Every Singlet pouch is as accurate as a newly opened bottle of buffer.
