56.3 cm = —————— mm king hendry died by drinking chocolate milk
K h. d. b. d. c m
Kg hg daG g dg. cg mg
KL hL daL L. dl. CL ML
Km hm dam M. dm. cm mm
king = kilo hendry = hecto died = deca by unit base = deci chocolate = centi
milk = Milli

56.3 cm the decimal place move one place
Demal move > to the right centi to milli. Then would be 563 mm (millimeters)

356.8 mL= —————— L. king hendry died by drinking chocolate milk
K h. d. b. d. c m
Kg hg daG g dg. cg mg
KL hL daL L. dl. CL ML
Km hm dam M. dm. cm mm
king = kilo hendry = hecto died = deca by unit base = deci chocolate = centi
milk = Milli

356.8 mL move from milliliters to liters. Milliliters is right we have to move to liters that decimal. Move 3 decimal place left. Now we have .3568 L

673.1 g = —————- kg king hendry died by drinking chocolate milk
K h. d. b. d. c m
Kg hg daG g dg. cg mg
KL hL daL L. dl. CL ML
Km hm dam M. dm. cm mm
king = kilo hendry = hecto died = deca by unit base = deci chocolate = centi

Pipette are used

To accurately and precisely transfer very small volumes of liquid.

Pipette are measured

Microliters there are about 50 microliter in just one drop of water.

First using the micropipette first you will

Set the volume you want to transfer by gently rotating the plunger on the top micropipette.

Pipette there is two stop on the plunger

The first stop going to correspond to the volume set.
The second stop when you are delivering the liquid.

( first press first stop then insert the pipette in the liquid 1cm into the liquid slowly and evenly bring the plunger back up.

( keep it slow, verticals, accurate)

The volume read in pipette

The volume in the pipette is read from the bottom of the meniscus.

What about small volume?

Physiology, cell biology, biotechnology and other fields require transfer of much smaller volumes of fluid.

Units are often in microliters (uL)
1 uL= 10-6 L (one - millionth of a other)
So, 1000 uL = 1 ml

Pipette plunger to pick volume or to deposit volume.
Volume adjustment knob

Volume indicator 3 digit number

Laboratory glass ware

Volumetric flask

Volumetric flask are used

These are used in creating an reagent where you need high accuracy because they like the volumetric pipet cousin

Volumetric flask calibrate

They are calibrate to one volume as noted by the dash line that is accurate up to. Any thing out that range will be not accurate volume.

Rest glass are graduated

Erlenmeyer flask
Graduated cylinder
Beaker

Erlenmeyer flask

They are ranging varieties. Meaning difference size glass.

Graduated cylinder

There are variety of volume. Meaning they are difference glass graduate cylinder

Beaker

There are variety of beaker volume. The beaker are not very accurate and you will not used them for anything other than holding something that you might be taking from to make accurate measurements. Maybe using pipette by using a large amount of fluid in the beaker to store in the beaker if you are not going to use it.

Graduated cylinder to measure the accuracy

Of a volume that are coming out of the different pipettes that we used.

Important of the glass ware id size that most befit volume that we looking to measure.

Example: 5 milliliter = use the one that goes 100 or use the smaller that goes to 10. Use the smaller one that goes 10 is best fit for the volume.

Units of measure is

Standardized amounts of various physical quantities.

Si system

International system of measure used by scientists. A very comprehensive with many units of meaure.

Unit conversion A weightlifter can lift 495lbs. How many kg is that?

1 kg = 2.2 lbs 495 lbs x ( 1 kg / 2.2 lbs) lbs cancel. We have kg. 225 kg

Example: calculate the amount of 10ul forward primer solution to add to a PCR reaction ( 25 cuL total reaction) to make a final concentration of 0.4 um forward primer in the reaction.

C 1= start 10 um V1 =Volume = x C2 = Final 0.4 m V2= final 25 uL Step 1 ) 10 x v1= 0.4 x 25 = Step 2 ). 0.4 x 25 / 10 x v1 = 1 uL

EXAMPLE: CALCULATE THE AMOUNT OF WATER YOU NEED TO ADD TO MAKE A FINAL CONCENTRATION OF 70% ETHANOL SOLUTION BY USING 100 ML OF PURE (100%) ethanol. C1v1=c2v2

C1= 100% ethanol V1= 100 ml C2= 70% ethanol V2= 100% ethanol x 100 ml = 70 % ethanol x V2 100 x 100/ 70 x v2 = 142.857143 round it up 142.9 ml for v2

Multi step unit conversion Thomas dropped off two package to be shipped. One package weight 1.38 kilograms and the other package weight 720 grams. What was the combined weight of both package in gram?

1 kilogram = 1000 gram 1.38 kg = If we multi ply 1.38 kg to 1 kg gram cancel . 1.38 time 1000 grams = 1,380 GRAM 1,380 GRAMS + 720 GRAMS = 2,100 GRAMS

JULIA AND HER FRIENDS ARE MAKING KITE OUT OF PAPER. FOR EACH KITE, THEY NEED A PIECE OF PAPER THAT IS 0,65 METER WIDE. HOW MANY CENTIMETERS OF PAPER WILL THEY NEED TO MAKE 4 KITES? 1 METER = 100 CENTIMETER.

1 M X 0.65 M = CANCEL M 0.65 X 100 CM = 65 CM 65 CM X 4 K = 260 CM OF KITE
