It is advisable that everyday when you start the pipetting in the lab check your micropipette for its reading correctness.
How to read a micropipette. Micropipetter one color are read as XXX µl. Maximum volume 1000 µl 1 ml. Accurate between 200 µl and 1000 µl.
Numbers on the micropipetter typically red-black-black are read XXX ml. Note that this micropipetter reads milliliters while the other two read microliters. The examples below show how to read the micropipettor.
On the body of the micropipette is a small vertical window with three numbers. These numbers read from the top down tells the user how much volume the micropipette is currently set at. To change the numbers grasp the black dial or plunger and gently twist.
The numbers will then change. Micropipette one color are read as XXX l. Maximum volume 1000 l 1 ml.
Accurate between 200 l and 1000 l. Numbers on the micropipette typically red-black-black are read XXX ml. Note that this micropipette reads milliliters while the other two read microliters.
Load a sterile tip. Micropipette allows you to adjust the volume that is measured. It can be dialed to the left or right to increase or decrease the volume.
Volume adjustment dial The digital readout shows the volume that will be measured. As you turn the volume adjustment dial the numbers in the digital readout will change. Digital readout shows the volume you.
The proper technique to have while using a micropipette. Press and hold the plunger at the first stop. Place the tip in the liquid.
Slowly release the plunger. Pause for a second and then move the tip. Insert the tip into the delivery vessel.
Press the plunger to the second stop. After carrying the micropipette properly in your working hand press the upper knob to the first stop. Immerse the micropipette tip into the solution approximately 3 mm deep into the sample liquid.
Slowly release the pressure from the knob and let it come to the. On the body of the micropipette is a small vertical window with three numbers. These numbers read from the top down tells the user how much volume the micropipette is currently set at.
To change the numbers grasp the black dial or plunger and gently twist. The numbers will then change. Micropipette Used to measure and transfer small volumes of liquid.
P10 05-10μl P20 1-20μl P200 20-200μl P1000 100-1000μl Micropipette Tips are usually color coded to the correct micropipette. P10 white P20 and P200 Yellow P1000 Blue. The eject button is used when discarding the plastic tip.
The volume knob is used to adjust the volume for each micropipette. The number windows display the set volume based on the adjustments made on the volume knob. The tip of the micropipette is the part of the micropipette that will attach to the plastic tips.

A P1000 micropipette is 200-100 0. The first digit on top is thousands and it will only show 1 and never go past it. Second digit is hundreds and third is tens.
1000 is read as 100 and 500 as 050 on the pipette. Micropipettes are the type of air displacement pipettes that are used to transfer the small quantities of solutions measured in microliters 1000 µl microliters equals to 1 ml milliliter and is the maximum amount that is commonly dispensed with the micropipettes. Micropipettes are of two types the Fixed micropipettes and the Variable Micropipettes.
Remove the lid from the box containing the correct size micropipette tips. P-1000 tips may be blue or clear while P-20 and P-200 tips are yellow or clear. Attach the tip by inserting the shaft of the micropipette into the tip and pressing down firmly.

For this set the micropipette at the nominal volume and dispense distilled water at least 5 times. Calibrating a Micropipette Martin de Groot Kelvin Training This paper discusses the calibration of pipette with particular attention to the type that is used and calibrated most frequently. This is the so-called air-displacement pipette single channel adjustable volume pipet.
The new ISOIEC 17025. Choose a micropipette and set the volume by loosening the black lock lever turning the thumb knob to set the volume and then gently tighten the lock lever. Make sure to recognize the decimal point for your micropipette indicated by the in the table below and to stay within the volume range.
Operating the Micropipette Always open the volume control above the final setting you need and then go down to that setting. This helps ensure the accuracy of the internal mechanism. Operating the Micropipette Step 1.
