Micropipettes. Measuring volumes which are what we scientists call “very, very small”. MICROPIPETTE RULES. Don’t set the pipettes past their intended range (high or low), even though you can – set the pipette volume only within the range specified for that micropipette

Measuring volumes which are what we scientists call
“very, very small”
1st stop: Exact volume to which the pipette is set. Press to this stop before immersing pipette tip in the desired solution.
2nd stop: Use when dispensing solution. Pushes an extra volume of air to dislodge any solution adhering to the tip.
How to pipette
2 - 20 µL
10 -100 µL
20 - 200 µL
Range is printed on the button or on the side
Use medium sized yellow tips
We will be using P-20 and P-200 pipettes
P-20 has a range of 2 - 20 µL
10 -100 µL
This pipette is set to its maximum:
High Range: 200-1000 µL
Use large blue tips
Digits from top to bottom represent:
The 1’s are indicated by the tiny white tick marks in the dial with the 10’s. Marks are in increments of 2 µL
This pipette is set to 1000 µL
This pipette is set to
