pH Buffer Starter Kits (pH 4, 7, 10 & 4M KCl)

The core of this kit is the set of three precisely standardized buffer solutions: pH 4.0, 7.0, and 10.0 (500 mL each). These standards are critical for performing multi-point calibration of your pH meter, spanning the acidic, neutral, and alkaline ranges. The kit also includes 125 mL of 4M Potassium Chloride (KCl) Solution, which is the recommended solution for filling, storing, and conditioning reference electrodes, ensuring rapid response times and maximizing electrode life. Choosing this pre-mixed kit eliminates all in-house preparation, guaranteeing consistent and traceable results.

Features:

• All-in-one starter kit for pH meter calibration and electrode maintenance
• Includes three critical, pre-standardized buffer solutions (pH 4.0, 7.0, and 10.0)
• Contains 4M Potassium Chloride (KCl) Solution for optimal electrode storage and conditioning
• Eliminates time-consuming and error-prone in-house solution preparation
• Ideal for new labs, educational settings, or simplifying routine maintenance
• All buffer solutions are 500 mL and the KCl solution is 125 mL
