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 tube not to lose shape or allows the liquid to come out when the microtube undergoes lab conditions such as heating, cooling, spinning, boiling etc. the microtube holds a volume of about 0.01 ul to 1.00 ml of liquid.
Claims18
A microtube, comprising:
- a distal end with a closed conical bottom;
- a proximal end having an opening to house a plug of a cap;
- the cap having a lip for opening and closing the tube and having a multiple configuration;
- and
- an inner first ring of the cap that is concave in shape on the upper side and depressed lower than an inner second ring on the cap to allow an optical intensity to be read accurately.
A microtube, comprising:
- a tubular structure having a distal end and a proximal end, wherein the proximal end is wider than the distal end;
- a cap to close the proximal end, wherein the cap has a concave recessesion in the center for optical clarity and having a multiple configuration;
- and
- a hinge that connects the tubular structure and the cap so that the cap is secure and easy to operate.
A microtube, comprising:
- a cap with a recessed concave portion, wherein the concave portion is optically clear and is at least 20-80% of the cap surface and has a thickness from 0.025 mm to 1.0 mm and having a multiple configuration;
- a hinge that connects the tubular structure and the cap so that the cap is secure and easy to operate;
- and
- a tubular structure having a distal end and a proximal end, wherein the proximal end is wider than the distal end, wherein the distal end has a closed conical end.
