pH Buffer Calibration Solution Tablets- pH 4.00- 7.00 and 10.00- Color Coded- Precise and Easy Calibration of All pH Meters -30 Tablets Total- 10 at Each pH Value-

Our new pH buffer tablets are the most environmentally friendly way to calibrate your pH meters. Instead of being packaged in a large plastic bottle or in individually wrapped, wasteful packets ours are packed 10 tablets to one compact, easy to store sleeve Sealed in airtight, foil packaging, our tablets will last and remain accurate for five years. Powders tend to be messy and require all the powder from the pouch to be poured into your liquid solution, otherwise it will not be accurate. Bartovation pH tablets eliminate this problem, allowing you to easily press one tablet out of the blister packaging. This also enables these pH tables to have an industry leading margin of error (+/- .05 pH for each tablet) This item comes as three, ten tablet sleeves, one sleeve for each pH value (4,7 and 10) that are designed to calibrate a solution at 25 °C. Instructions: 1. Dissolve one pH buffer tablet in 20 mL of deionized / distilled water 2. Wait approximately two minutes, mix gently. After time elapses, the buffer calibration solution is ready to use! NOTE: There will be undissolved particulate that settles to the bottom of the container. This is normal and does not impact accuracy. pH 10 will produce a green solution, pH 7 will produce a yellow solution, and pH 4 will produce a pink solution. THESE TABLETS ARE NOT FOOD. DO NOT EAT THESE TABLETS. DO NOT DRINK THE RESULTING SOLUTION.
