LAB A: 1.2 Micropipette techniques Flashcards
function and volume range of a micropipette
to measure small volume of liquid
0.5 - 1000 uL
Plunger
top most part
adjusts the volume and aspirate
rotation of the plunger for increase/decrease
anticlockwise - increase
clockwise- decrease
tip ejector
used to remove the micropipette tips
volume window
see the amount of quantity
shaft
tube filled with air which sucks and release the volume
pipette tip
attached at the end; collect and transfer the sample
P-20
2-20 uL white
p-200
20-200 uL yellow
p-1000
100-1000uL blue
type of micropipette base on working principle
air displacement micropipette- the volume of the air displaced corresponds to the same amount of aspiration volume
positive displacement pipette- the piston moves up and down with no air included
types of micropipette based on working mechanism
mechanical pipette- operated by hand
electronic micropipette- automatic operation
types of micropipette based on the no. of channels
single channel micropipette-
multi-channel micropipette- 8, 12, 16
types of micropipette based on volume capacity
fixed volume
adjustable volume- the amoun of liquid to be aspirated can be changed
