Abstract
A microtube with a novel recessed concave top is described. The recessed top is at least 20-80% of the area of the entire cap and has a thickness from 0.025 mm to 1.0 mm. The recessed portion is smooth in structure and is optically transparent to allow all instrumental reading based on optical value reliable and accurate. The cap also has a unique plug design that has two parts. One part is the lower part that is a bit broader than the upper part. The upper part is a bit smaller than the opening. This structure allows the microtube maintain the structure and prevents the liquid from coming out when the microtube undergoes lab conditions such as heating, cooling, spinning, and boiling. The microtube holds a volume of about 0.01 ul to 1.00 ml of liquid.
