The main function of the cover slip is to keep solid specimens pressed flat, and liquid samples shaped into a flat layer of even thickness. This is necessary because high-resolution microscopes have a very narrow region within which they focus.
The cover glass often has several other functions. It holds the specimen in place and protects the specimen from dust and accidental contact. It protects the microscope's objective lens from contacting the specimen and vice-versa; also the cover slip can be glued to the slide so as to seal off the specimen, retarding dehydration and oxidation of the specimen.
 Cover slip(also called coverslip or cover glass) is a thin flat piece of transparent material, usually square or rectangular, that is a placed over objects for viewing with a microscope. And it is made of high-quality clear glass with no blister or flows.

Tape measure is a common measuring tool in daily life. You often see one of the necessary tools for families. Luban ruler, Fengshui ruler and Wengong ruler also belong to steel tape. Steel tape is a common tool in construction and decoration.
Steel tape can be divided into self winding tape, braking tape and rolling tape. Other names: steel tape and steel box tape.
The second is the fiber tape measure, which is the tape measure that we often see. Many people say that it is cloth measure, waist measure, tailor measure / garment measure. In the south of China and Hong Kong, it is often called tape measure or slide rule. Its material is PVC plastic and glass fiber, glass fiber can prevent the tape from being elongated in the process of using. Gift ruler is used for advertising and promotion. It is divided into steel tape (steel strip) and leather tape (PVC plastic fiber tape). It is usually cute and small.
It is mainly composed of shell, ruler bar, brake, ruler hook, lifting belt, ruler spring, anti falling protective sleeve and labeling
1. Shell: new ABS plastic, glossy appearance; anti falling, wear-resistant, not easy to deform.
2. Ruler bar: 50 # grade I strip steel with thickness of 10 wires (0.10 mm); ruler surface is the most advanced environmental protection paint: tasteless, smooth and wear-resistant, bright color, clear and bright scale
3. Braking: it has three-dimensional braking of upper, side and bottom, with stronger hand control feeling.
4. Ruler hook: rivet ruler hook structure, not easy to deform, to ensure more accurate measurement.
5. Strap: rubber, nylon two kinds; high quality; durable, good handle.
6. Ruler spring: 50 # carbon steel, 65 # manganese material: strong toughness, high accuracy.
7. Anti falling protective cover: high quality plastic, prevent falling and collision damage, enhance durability.
8. Labeling: according to customer requirements labeling production.
Super hardness,The scale is clear,High straightness
