Taylor Technologies, Inc. products

Reagent Pack, Buret, Alkalinity (P/M&P/T), Phenolphthalein/Methyl Orange/Blended Indicator, 1mL=5mg. High halogen level may change indicator reaction from green/red to blue/yellow; to prevent, add thiosulfate prior to testing. Filming amines, quats, and biguanides may interfere and cause the endpoint to look purple; to prevent, add 10 drops of R-0884 prior to testing.

Reagent Pack, Buret, Hardness (calcium/total), EDTA, 1 mL = 1 mg. Metal ions may cause interference; to prevent, add titrant containing EDTA to sample before buffer and indicator, then test as normal making sure to count drops of titrant added initially in total required to reach endpoint. If interference still occurs, dilute sample with DI water as necessary and retest. Quats may cause interference.
