Single-Blind Research Method. The Single-Blind research method is a specific research procedure in which the researchers (and those involved in the study) do not tell the participants if they are being given a test treatment or a control treatment. This is done in order to ensure that participants don't bias the results by acting in ways they think they should act.
They provide accurate measurements of very small volumes of liquids in the userâs quest to obtain correct test results. But pipettes are mechanical devices that require regular calibration service to maintain their accuracy and precision. The similarities are not unlike the maintenance of your car. Without regular service and repair, your car can break down, leave you stranded and result in high repair costs. Pipettes are no different.
Under no circumstances should the pipette be used without a tip. Use the small yellow or clear tips with the P20 and P200, and use the medium blue tips with the P1000. The smallest set of tips are only to be used with the P10. Image i.1 A set of pipettes in the biochemical methods lab.
