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.
While it should not form the sole basis of calibration intervals, inevitably it is necessary to consider the cost of regular calibration. This is why it is often necessary to bring in a usage system, or a system that operates various frequencies, as this means you can control costs more effectively.he first thing to check in these situations is whether a specific standard for the equipment you are using states the frequency requirement. On occasion a standard will explicitly state how frequently equipment should be calibrated if it is used for certain things (i.e. for measurement of exhaust emissions).
