LAB 02: Measuring and Dispensing Liquids Introduction Pipetting is one of the most important and basic skills when it comes to experimental science. Good pipetting skills allow an individual to put trust in his or her results‚ prevent waste of materials‚ and assure reproducibility of results. In order to correctly pipette liquids‚ the volume range must be first determined. p1000 micropipettes have a volume range of 200 - 1000 uL‚ p200 micropipettes have a volume range of 20 - 200 uL‚ and p20 micropipettes

In conclusion the pressure calibrator and temperature calibrator were proved to be accurate in their measurements through the use of plots‚ data analysis and statistical analysis methods.

industry‚because of its non-contact measurement‚ and strong anti-interference‚ etc‚. However‚ its accuracy is difficult to reach the micron-level. This paper uses the accuracy analysis theory and the software error correcting technology to calibrate measurements. Besides‚ it gives an effective principle‚ which uses “minimum interval” and “maximum ranges segment” to determine the optimum operating ranges of eddy current sensor‚ to improve the sensor’s measurement accuracy. This method is used in

Abstract- The development of De-Sauty’s bridge for capacitance measurement has been followed by various modifications and improvements in the original circuit. Lately Schering bridge and transformer ratio arm bridge have been used for measurement of capacitance in a circuit.Today there is instrumentation available that makes use of these bridges in real life such as that can measure the quality of electrical insulation at power frequency as well as in touch-sensitive sensors.

Measurement Devices Objectives: • To know how to use the different measuring devices properly. • To know how to solve the volume. • To know how to solve the Density. Introduction: "Accurate measurement is essential" – Measurement is the size‚ length‚ or amount of something‚ as established by measuring. Measurement is the first step that leads to control and eventually to improvement. If you can’t measure something‚ you can’t understand it. If you can’t understand it‚ you can’t control it. If
