一、概述1.检定依据JJG646-2006《移液器检定规程》。2.环境条件温度:(20±5)℃;水温与室温的温差不超过2℃。3.测量标准METTLER TOLEDO XSE205电子天平。4.被测对象eppendorf(20～200)μL可调移液器(内活塞式)。5.测量过程采用质量法,通过电子天平称量移液器吸取的介质质量(介质采用蒸馏水)m,再测得介质温度t,通过查K(t)值表,计算实际质量V_(20)。重复测量6次,用6次测
First, an overview 1. Accreditation based on JJG646-2006 “pipette test procedures.” 2. Environmental conditions temperature: (20 ± 5) ℃; temperature and room temperature does not exceed 2 ℃. 3. Measurement standards METTLER TOLEDO XSE205 electronic balance. 4. The test object eppendorf (20 ~ 200) μL adjustable pipette (piston). 5. Measurement process using the quality of law, through the electronic balance pipette to measure the quality of the medium (medium using distilled water) m, and then measured the medium temperature t, by checking K (t) value table to calculate the actual mass V_ (20) . Repeat the measurement 6 times, with 6 measurements
