08006-02 Galileo Thermometer; 64 to 80°F (18 to 26°C), 7 in. by Digi-Sense

Colorful glass thermometer is based on Galileo's theory developed over 400 years ago: in liquid, a body of fixed mass becomes less buoyant as the liquid temperature rises, and more buoyant as the temperature decreases - due to changes in liquid density. As temperature changes, the multi-colored balls rise and fall within the liquid-filled thermostatic tube. Lowest sphere in the top group within the instrument indicates ambient temperature.

• Hand-crafted thermometers
• Non-mercury liquid
• Five floating spheres provide both Fahrenheit and Celsius readings
• Seven inches tall

*Please note we can only ship RKI products to customers within the United States

WD-35850-16 Buffer Capsules, pH 10; 10/Pk by Oakton

Buffer salts inside capsules require 100 mL of deionized or distilled water to produce a clear pH calibration solution accurate to ±0.02 pH (at 25°C) with traceability to NIST standards. Capsules are easier to store and transport than prepared aqueous buffer solutions. Capsules are color-coded for easy identification if mixed.

Store buffer solution in an airtight container at room temperature for three weeks. Unused capsules have a five-year shelf life. Each vial contains 10 capsules.

Fresh pH calibration solution anytime and anywhere

• Each capsule mixes with 100-mL of deionized water to create a clear, 10.00 pH solution

Includes

Ten blue-colored capsules.
