When the operating button is pressed again ‚ the piston descends ‚ expelling the liquid from the tip. We need to optimize volume range by selecting the correct volume pipette . We must work in the 35% to 100% volume range for best accuracy and precision . Besides that ‚ the tip immersion angle also plays an important role . Nextly‚ the micrometer setting must be done using the correct technique . If filled ‚ we should not lay the pipette down or hold more than 20º from vertical . Lastly ‚ we should

Lab No.1: density‚ accuracy and precision Aim: to determine the relative precision and accuracy of different glassware items by calculating the density of a known substance. Introduction: the density of a substance is its mass per unit volume. (where P-density‚ m- mass and v- volume). Different materials usually have different densities and densities vary according to the pressure‚ temperature and purity of a substance. When measuring‚ there is always a small uncertainty or error and therefore
