Because you open a fresh sachet each time, the buffer is as good as the day it was packed, with no worries about a half-used bottle going off or becoming contaminated. The lot number and expiry date are stamped on every sachet, and an unopened sachet is formulated to last 2 years from the date of manufacture. The solution contains no dyes, so there's nothing to stain the reference cell of your electrode, and the colour-coded label makes it easy to tell buffer values apart.\u003c\/p\u003e\u003cp\u003eIt suits hobbyists who calibrate occasionally rather than every week, and anyone who wants a compact option for testing away from the tank or on the road.\u003c\/p\u003e\u003cp\u003eSpecs: pH 4.01 at 25°C, accuracy ±0.01 pH, 20 mL, 1 sachet.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67662792458466,"sku":null,"price":7.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/1284\/4602\/files\/hanna-ph-4-01-calibration-buffer-sachet-20-ml-1.png?v=1791782123"},{"product_id":"hanna-ph-10-01-calibration-buffer-sachet-20-ml","title":"Hanna pH 10.01 Calibration Buffer Sachet (20 mL)","description":"\u003cp\u003eThis is a single-use sachet of pH 10.01 calibration buffer, holding 20 mL of standard solution.
