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.
A pipette or dropper is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser.olumetric pipettes or bulb pipette allow the user to measure a volume of solution extremely accurately (accuracy of four significant figures). These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume (like a volumetric flask).
