{"product_id":"hy-gen-ph-electrode-storage-solution","title":"HY-GEN pH Electrode Storage Solution","description":"\u003cp\u003eA pH meter only reads as well as the glass bulb on the end of its probe, and how that bulb spends the hours between readings matters as much as the readings themselves. HY-GEN pH Electrode Storage Solution gives the electrode a proper place to rest. HY-GEN make it to the same formula scientists use in laboratories to store glass pH electrodes, and they say it maximises electrode performance and extends electrode life.\u003c\/p\u003e\u003cp\u003eWhy does storage matter so much? A glass pH electrode reads through a thin hydrated layer on the surface of its bulb, and that layer only responds properly while it stays wet. Let a probe dry out and it turns slow and starts to drift. Plain water isn't the fix. HY-GEN warn that distilled water causes ions to leach out of the glass bulb and renders the electrode useless. Buffer solutions are no good for storage either, however handy the calibration bottle looks.\u003c\/p\u003e\u003cp\u003eThe formula is short and deliberate. It's mostly water carrying potassium chloride, the same salt most pH electrodes hold inside their reference half, with a small amount of potassium hydrogen phthalate, a compound chemists also use when making reference buffers. HY-GEN make their calibration and care solutions to international standards from high quality analytical grade constituents, the same quality laboratories use for cleaning and storing electronic meters.\u003c\/p\u003e\u003cp\u003eStorage is one half of looking after a probe. Over time an electrode picks up a coating of contaminants, and HY-GEN pair this solution with HY-GEN Probe Cleaner: the cleaner strips that coating away before you calibrate, and the storage solution keeps the bulb in good condition until the next reading. Between the two, the meter you rely on for every feed stays accurate for longer!\u003c\/p\u003e","brand":"HY-GEN","offers":[{"title":"250 ml","offer_id":67551784075422,"sku":"9334851000799","price":8.99,"currency_code":"AUD","in_stock":false},{"title":"500 ml","offer_id":67551784108190,"sku":"PLACEHOLDER920005","price":11.25,"currency_code":"AUD","in_stock":false},{"title":"1 L","offer_id":67551784140958,"sku":"9334851000812","price":22.49,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/HY-GEN_pH_Electrode_Storage_Solution.png?v=1793773588","url":"https:\/\/www.hydrooasis.com.au\/products\/hy-gen-ph-electrode-storage-solution","provider":"Hydro Oasis","version":"1.0","type":"link"}
