{"product_id":"gf-signet-ph-orp-buffer-solutions","title":"pH\/ORP Buffer Solutions","description":"\u003cp\u003eThe Signet pH buffers are ideal for many calibration requirements. The liquid solutions are conveniently packaged in one pint bottles; the powder pillows are packaged in low weight, single-use containers which can be mixed with water. All pH buffers are color coded for easy identification; 4.01 pH is red, 7.00 pH is yellow, and 10.00 pH is blue.\u003c\/p\u003e\n\u003cp\u003eThe pH buffers are traceable to NIST standards and certificates are available upon request. They are accurate to within ± 0.01 pH units at 25 degrees C and have long term stability.\u003c\/p\u003e\n\u003cp\u003eThese solutions are temperature sensitive and are provided with temperature correction values for the most accurate calibration. For applications that require ORP calibration, the pH 4 and pH 7 buffers can be mixed with quinhydrone powder for the correct measurement values of +87 mV and +264 mV respectively.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNIST traceable\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEasily identifiable color coded buffer solutions\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLiquid or powder versions\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTemperature compensated values\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eKits for easy use\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GF Signet","offers":[{"title":"Calibration kit; includes 3 polypropylene cups, box used as cup stand, 1 pint pH 4.01, 1 pint pH 7.00","offer_id":47325517316308,"sku":"3-2700.395","price":108.0,"currency_code":"USD","in_stock":true},{"title":"20 gram bottle quinhydrone for ORP calibration","offer_id":47325517349076,"sku":"3822-7115","price":150.4,"currency_code":"USD","in_stock":true},{"title":"pH 4.01 buffer solution, 1 pint (473 ml) bottle","offer_id":47325517381844,"sku":"3822-7004","price":32.8,"currency_code":"USD","in_stock":true},{"title":"pH 7.00 buffer solution, 1 pint (473 ml) bottle","offer_id":47325517414612,"sku":"3822-7007","price":32.8,"currency_code":"USD","in_stock":true},{"title":"pH 10.00 buffer solution, 1 pint (473 ml) bottle","offer_id":47325517447380,"sku":"3822-7010","price":32.8,"currency_code":"USD","in_stock":true},{"title":"pH buffer kit (1 each 4, 7, 10 pH buffer in powder form, makes 50 ml of each)","offer_id":47325517480148,"sku":"3-0700.390","price":6.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/2424\/0340\/files\/products_GF-Signet-pH-ORP-Buffer-Solutions.jpg?v=1765199310","url":"https:\/\/alscoind.com\/products\/gf-signet-ph-orp-buffer-solutions","provider":"Alsco Industrial","version":"1.0","type":"link"}
