Technical InfoInstructionsCover SlipsClose ΛCover slip is a piece of glass that covers the biological specimen in a microscope specimen. Cover slip is generally made of square and round, and its size is typically smaller than glass slides, with a standard thickness of 0.17 mm. After imaging is formed by the objective lens and upon passing the clover slip, the front length is changed, so the manufacturer usually follows the 0.17mm manufacturing standard of thickness of the cover slip. When the objective lenses of different manufacturers are interchanged, the difference of this parameter may affect the parfocality of a set of objective lenses, that is, when the nosepiece is rotated, the objective lens will be defocused, leading to the lowering of the image quality. Some professional objectives may not require the use of cover slips, or may be equipped with focal length correction rings that replaces the thickness of the cover slips, so as to accommodate applications where cover slips cannot be used.
Cover slip can flatten the solid slice sample to form the liquid sample into a flat layer of uniform thickness, so that the plane of the slice is kept equidistant from the objective lens, to avoid repeated adjustment of the focal length of the objective lens during observation. Cover slip can seal the sliced sample, thereby delaying the dehydration and oxidation of the sliced tissue. Cover slip can keep the slice in an appropriate position so as to avoid dust and accidental touches. In microscopic observation and use, cover slip can prevent the microscope objective from touching the sample slice, or making the slice dirty or contaminating the objective lens. Especially when using an oil immersion objective lens, cover slip can prevent contact between the immersion liquid and the sample. PackagingClose ΛAfter unpacking, carefully inspect the various random accessories and parts in the package to avoid omissions. In order to save space and ensure safety of components, some components will be placed outside the inner packaging box, so be careful of their inspection. For special packaging, it is generally after opening the box, all packaging boxes, protective foam, plastic bags should be kept for a period of time. If there is a problem during the return period, you can return or exchange the original. After the return period (usually 10-30 days, according to the manufacturer’s Instruction of Terms of Service), these packaging boxes may be disposed of if there is no problem.
