There are enough reagents for 300 tests and are for use with Hanna’s compatible benchtop and portable photometers. \u003c\/p\u003e\u003ch3\u003eReagents for 300 copper tests for HI-93702.\u003c\/h3\u003e \u003cp\u003eThe HI-93702-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow the bicinchoninate method in which the reaction between copper and the reagent causes a colour change in the sample. The intensity of colour is determined by a compatible photometer and the copper concentration will be displayed in mg\/L (ppm). These reagents are designed to be used with samples that have an expected range of 0.00 to 5.00 mg\/L copper.\u003c\/p\u003e \u003ch3\u003eTip for an accurate measurement\u003c\/h3\u003e \u003cp\u003eIt is important that the sample does not contain any debris.\u003c\/p\u003e \u003cp\u003eWhen the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI-731318 or a lint-free cloth prior to insertion.\u003c\/p\u003e \u003cp\u003eShaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.\u003c\/p\u003e \u003cp\u003eDo not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.\u003c\/p\u003e \u003cp\u003eAfter the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003epackets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e300 tests\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003ebicinchoninate method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640096792949,"sku":"HI-93702-03","price":146.59,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/reagents-for-300-copper-tests-for-hi-93702.jpg?v=1791581205","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-93702-03-reagents-for-300-copper-tests","provider":"Test All Water","version":"1.0","type":"link"}
