Taylor Technologies R-0004-A-24 pH Indicator Solution #4; 3/4 oz, Phenolic Red

This is a replacement Taylor pH Indicator #4 reagent. This replacement reagent has a bottle size of 3/4 ounce.

All reagents have a shelf life, whether they are liquids, powders, crystals, tablets, or test-strip pads. If kept dry, powders and crystals are very stable; acids are also long lived. Date of manufacture is not the controlling factor when it comes to shelf life – storage conditions are more important
