It is one of the reagents used in the calcium hardness step of a Taylor test kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat buffer does in the test\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA hardness titration only works if the sample sits in the right chemical conditions. The buffer puts it there, so that the indicator gives a clear color and the titrant reaches a sharp endpoint you can actually count drops to. Skip it or use a bottle that has gone off and the color change smears across several drops, which is where inconsistent hardness numbers come from.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHandling\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReagents are consumables with a shelf life. Keep the cap on, keep the bottle out of direct sun and out of a hot equipment pad, and replace opened bottles each season. If a result looks wrong, fresh reagent is the cheapest thing to rule out before you start doubting the water.\u003c\/p\u003e","brand":"Taylor Technologies","offers":[{"title":"Default Title","offer_id":48634988265684,"sku":"TAY-45-946","price":16.16,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_758765c7-87c6-4904-820d-17569a38a5df.jpg?v=1788839310","url":"https:\/\/www.activepoolsupply.com\/products\/calcium-buffer-2-oz-dropper-bottle","provider":"Active Pool Supply","version":"1.0","type":"link"}
