{"product_id":"ph-4-01-calibration-solution-quart","title":"pH 4.01 Calibration Solution - quart","description":"\u003cp\u003epH meters should be calibrated frequently (every 1-4 weeks, depending on use). \n  Two-point calibration (using both 4.0 \u0026amp; 7.0 buffers) ensures the most accurate \n  calibration possible. Do not reuse calibration solution, as once it has been \n  used, it is no longer sterile and may result in improper readings. Pour a small \n  amount into a shot glass and discard after use. Suitable for all makes and models \n  of pH pens and meters.\u003c\/p\u003e\n\u003cp\u003epH Calibration Solution is available in single-use sachets, as well as 230 \n  ml (approx. 8 ounces.) and quart bottles. We also offer a \"twin-pack\" \n  containing one 8 ounce bottle each of both 4.01 and 7.01 calibration solution. \n  All pH calibration solutions that we offer are made by either Hanna, Green Air \n  Products or General Hydroponics.\u003c\/p\u003e","brand":"BFG Supply","offers":[{"title":"Each","offer_id":41930540941397,"sku":"6142","price":14.54,"currency_code":"USD","in_stock":true},{"title":"Case of 12","offer_id":42385987371093,"sku":"6142-CS12","price":174.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/3426\/6709\/files\/ph-401-calibration-solution-quart-6142-3171491.jpg?v=1767475507","url":"https:\/\/www.bghydro.com\/products\/ph-4-01-calibration-solution-quart","provider":"BetterGrow Hydro","version":"1.0","type":"link"}
