Abstract: A lab consumable having a surface to display identifiers connected by a bridge encloses a tube. A specific sealer made up of hard and soft material is used close the tube. The connector for the sealer is made up of flexible, hard and various other material combinations. The surface where the identification is displayed has different surfaces and identifier. The identifier comprise of a number, alpha numerical, alphabets, symbol, barcode, customized sign, markings, hand written markings and a combination thereof.

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.

Abstract: A biodegradable bio-plastic material composition comprising of synthetic materials and biological/natural/second natural reusable material is described. The use of natural material that is easily degradable in landfill makes it easy to dispose the article and reduce green gas emission in the environment. Biological reusable materials may be one of polylactic acid based plastic, walnut, almond, coconut and other hard shells, hard skins from rice, wheat, flax, and other seeds, corn husks, and other organic biodegradable matter and synthetic materials may be polypropylene and/or polyethylene.
