Product Description

The Hanna Instruments 93705-03 silica reagent, for use with the HI 96705 Silica Portable Photometer, contains the proper dosage for 300 tests that measure the silica content using the LR heterophony blue method in water samples in the 0.00 to 2.00 mg/L range. HI 93705-03 contains three reagents; three bottles of an odorless, clear liquid reagent, 300 packets of an odorless, white powder, and 300 packets of a slightly pungent, white powder required for the three-step process.

A reaction between the reagents and silica in a sample causes a distinct blue color to appear, which is measured by the photometer. The photometer uses an adaptation of the ASTM D859 method of the heteropoly blue method.

Reagents are used in photometers to measure the light intensity of solutions or surfaces. The reagent is mixed with the sample and placed in the photometer, which then produces a reading. Reagents are commonly used in the water quality, agricultural, and horticultural industries to measure the amount of minerals and chemicals in water samples.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards.
