Applications and Experiments for the Glass Cover Slips
Cover slips can be used wherever a mount is made on a slide: onion peel and cheek cell preparations, pollen, root-tip squashes, pond-water organisms and stained smears. They suit NCERT Class 9–12 practicals, B.Sc. botany and zoology mounts and laboratory-technician training as everyday school biology lab equipment in India.
- Class 9 biology: covering onion peel and cheek cell mounts stained with dyes from the Stains and Reagents for Microscopy set.
- Class 11–12 and B.Sc.: temporary mounts of root-tip squashes, pollen grains and leaf peels viewed under Student Biological Microscopes.
- Wet mounts of pond water on plain slides such as Laboratory Microscope Glass Slides (Pack 50).
- Technician training: practising bubble-free mounting by lowering the slip at an angle onto the drop.

Frequently Asked Questions
What size and thickness are these cover slips?
Each slip is a 22 x 22 mm square between 0.13 and 0.17 mm thick. The square covers the central area of a slide where the specimen sits, leaving the ends of the slide free for labelling and handling.
How many pieces come in one box?
A box holds approximately 100 pieces, which together weigh about 10 g. Order by the box; the quotation then shows the number of boxes, the packing and the delivery time for your quantity.
Do the cover slips need cleaning before use?
They are supplied pre-cleaned, so they can go straight onto a mount. Handle them by the edges or with forceps to avoid fingerprints, and keep the box closed between practical sessions to keep dust off the glass.
Where can buyers obtain these cover slips?
Boxes of these cover glasses are supplied by Science Lab Supplies from Ambala, Haryana. Schools, colleges and distributors can request them on their own or on a combined microscopy quotation that lists packing and delivery time for each line.
