The amount of gas in test tubes can differ based on factors such as the volume of the test tubes, the pressure inside the test tubes, and the temperature of the gas. Different test tubes may contain different amounts of gas depending on these variables.
Different laboratories may use different color codes for test tubes depending on their specific protocols. However, a common color coding for test tubes used in centrifuges is as follows: red for serum tubes, lavender for EDTA tubes, green for heparin tubes, and blue for citrate tubes.
