How Is a Permanent Mount Made Under a Cover Slip?
In college botany and zoology practicals a stained section, such as a thin transverse section of a stem, is passed through increasing strengths of alcohol to remove water, cleared, and then given a drop of mounting medium such as DPX or Canada balsam. The cover slip is touched to the drop at an angle and lowered slowly with a needle so the medium spreads outwards and pushes air ahead of it; the slide is then left flat to set and labelled for the class slide collection. Handle cover slips by their edges, wipe them with alcohol and lint-free tissue before use, and drop broken pieces into a separate glass-waste container.
Frequently Asked Questions
Should I choose this 18 mm cover slip or the 22 mm one?
JLab also lists a square glass Cover Slip of 22 x 22 mm. The 18 mm size suits small sections and peels on a standard slide; the larger one covers bigger smears or several pieces mounted together.
How thick are they, and how many come in a pack?
Neither is stated in this listing, so both are confirmed in the quotation. High-power objectives are designed for a particular cover glass thickness, so mention it if your microscopes need a specific value.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a microscopy and biology lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The cover slips come from JLab’s own works rather than from a trader, so schools, colleges, dealers and importers buy them factory-direct. JLab exports worldwide and ships to buyers in every region — for example Tunisia in North Africa, Turkey in the Middle East, Jamaica in Central America and the Caribbean, Senegal in West Africa and Bolivia in South America. Tender details are on the JLab lab tenders page.
