Microscopy is the technical field of using microscopes to viewing objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical,electron, and scanning probe microscopy. I. Objective:- • Learn how to use a micropipettor II. Background:- Micropipettors are the standard laboratory equipment used to measure and transfer small volumes of liquids. You will use them throughout this semester and in advanced courses that you take in the future. It is essential that you master their use if you are to be successful in your experiments. A. Parts of a micropipette- a. Plunger button b. Tip ejector button c. Volume adjustment dial d. Digital volume indicator e. Shaft f. Attachment point B. Three sizes of micropipettes- The micropipettors in this laboratory come in three different sizes each of which measures a different range of volumes. The three sizes are P20, P200 and P1000. These sizes are noted on the top of the plunger button. Size Micropipette Range of volumes measured P20 0.5-20µl P200 20-200µl P1000 100-1000µl When scientists need to accurately and precisely deliver smaller volumes of a liquid, they use a pipette – a calibrated glass tube into which the liquid is drawn and then released. Glass and plastic pipettes have been mainstays of chemistry and biology laboratories for decades, and they can be relied upon to dispense volumes down to 0.1mL. Molecular biologists frequently use much smaller volumes of liquids in their work, even getting down to 0.1µL (that’s one ten thousandth of a millilitre, or one ten millionth of a litre!). For such small volumes, they need to use a micropipette. Micropipettes are called a lot of different names, most of which are based on the companies which manufacture. For example, you might hear them called “Gilsons”, as a large number of these devices used in laboratories are made by this company. Regardless of the manufacturer, micropipettes operate on the same principle: a plunger is depressed by the thumb and as it is released, liquid is drawn into a disposable plastic tip. When the plunger is pressed again, the liquid is dispensed. The tips are an important part of the micropipette and allow the same device to be used for different samples (so long as you change your tip between samples) without washing. They come in a number of different sizes and colours, depending on the micropipette they are used with, and the volume to be dispensed. The most commonly used tips are: Large Blue – 200-1000µL Small Yellow – 2-200µL Small White - <2µL They are loaded into tip boxes which are often sterilized to prevent contamination. For this reason tip boxes should be kept closed if they are not in use. Tips are loaded onto the end of the micropipette by pushing the end of the device into the tip and giving two sharp taps. Once used, tips are ejected into a sharps disposal bin using the tip eject button. Never touch the tip with your fingers, as this poses a contamination risk.
