100mm culture dish - (Apr/04/2005 )

When it says; "100mm culture dish" does it mean the diameter (100mm) of the dish or the square (100mm^2) of the dish?

Thanks.

Thanks.

I am almost positive that it means mm square, i.e surface.
Cheers

According to Corning:

100 mm style dish means actualy surface diameters of 80.5 mm with a approx growth area 55 cm^2. So 100 mm doesn't represent either area or diameter.

While 75 cm flasks have an approx. growth area of 75 cm^2.

My Falcon dishes say that they're 100mm in diameter x 20 mm high, but I haven't measure them. All these numbers (100 mm, 60 mm, 35 mm...) refer to the diameter, not the area, or the dishes. But then, some companies may have reduced it, thus giving us less for our money...

This URL may be useful (web.uvic.ca/~fnano/Culture.htm) and it states the following:

35mm--takes 2 ml of medium. It has an area of 8.55 square cm.
50 mm or 5 cm--takes 5 ml of medium. It has an area of 19.60 square cm.
100 mm or 9 cm--takes 10 ml of medium. It has an area of 56.75 square cm.
135 mm--takes 20 ml of medium. It has an area of 143 square cm.
A well on a 24 well plate has an area of 1.89 square cm and takes 1 to 2 ml of medium.

100 mm stands for the diameter of the plate.

If the measurement is mm2 etc. like 75 cm2 then it is referring to surface area.
