DescriptionOur use of food-grade, virgin plastic promises greater durability against low temperatures, as well as enhanced flexibility and more pristine clarity. These microtubes were produced with the intention of easy manipulation within a laboratory setting. The extended lip affords simple opening and closing, with the tube itself securely fitting into racks. These design features help speeds of research while also limiting risk of spillage.Features- Color: Transparent. - Material: Plastic. - Size: 4.00 x 1.30 x 1.30cm/ 1.57 x 0.51 x 0.51 inch. - Mini plastic centrifuge tubes, conical bottom with lids, they are easy to fill and the lids fit tightly, no leaks. - Smooth wall products, good transparency, accurate measurement scale, the lid is suitable for high-speeds centrifugal force. - Clear graduation on the wall of the reaction vessel for easier observation. - Widely used in laboratory, research facility, food coloring, craft, etc. - The use of high-quality plastic materials, smooth inner wall, can effectively reduce liquid adsorption.
