maybe 20 but im trying to answer this question myself! It depends on the radius(r) and length(L). Test tubes consist of a cylindrical section and a spherical portion. Assuming the spherical portion is a perfect hemisphere, the cylindrical portion is L-r, and the volume for that is (L-r)(r^2)pi. the hemispherical portion is (2/3)pi(r^3). So for a 1.6X12.5cm test tube its volume is (12.5-.8)(.8^2)(3.14)+(2/3)(3.14)(.8^3)=25mL.
A test tube (or sample tube) has no errors.
A test tube can be held upright using a test tube rack, a test tube holder, or a clamp attached to a stand. These tools provide stability and prevent the test tube from tipping over during experiments.

When sugar dissolves in water, it occupies space within the water molecules, leading to an increase in volume. So, if you dissolve a half test tube of sugar into a half test tube of water, the volume of the mixture will be greater than the sum of the individual volumes of sugar and water, resulting in a full test tube.

Volume of a cylinder (the test tube) = pi*radius2*height or length Volume = pi*15.52*204 = 49011*pi cubic mm
13x100 test tubes are excellent when you need to have larger volume in a test tube. These larger tubes allow more air to touch the sample.
a test tube is the answer
A small clean test tube typically has a size of about 13mm in diameter and 100mm in length, with a volume capacity of around 10-15 milliliters.
A lavender-top tube (EDTA) is typically used for the Complete Blood Count (CBC) test, which includes the measurement of cell volume and numbers.
A test tube is a container used for holding, mixing, or heating small amounts of liquid during experiments or chemical reactions. It does not measure anything on its own, but is a versatile tool in laboratories for conducting various tests and analyses.
