Glass Coverslips for Microscopy (10g)

Product Code : SCL-MSAC-12211

Glass Coverslips for Microscopy (10g) (SKU SCL-MSAC-12211) are clear, square borosilicate glass cover slips measuring 20 x 20 mm, sold by weight in a 10 g pack. Laid over a specimen on a microscope slide, they keep solid samples pressed flat, spread liquids into an even layer and keep the sample off the objective lens. They suit slide preparation in school, college, biology and teaching laboratories. The pack is supplied by Science Lab Supplies from Ambala, India to schools, colleges, laboratories and distributors.

Specifications

The table gives every specification of the 20 mm coverslip pack. In short, these are clear, square cover glasses of borosilicate glass, 20 x 20 mm each, packed by weight at 10 g per pack for laboratory use; the piece count per pack, thickness and edge finish are confirmed on the quotation.

Applications and Experiments for the Glass Coverslips

Coverslips are needed whenever students make their own temporary mounts. Placed over a drop of water, stain or a thin section, a 20 mm square flattens the sample to an even depth, cuts glare from the liquid surface and stops the objective lens from touching the specimen, giving a clearer image at higher power.

• Class 9 science: temporary mounts of onion peel and cheek cells in the cell practical.
• Class 11 and 12 biology practicals: stained mounts of plant sections, pollen and root tip squashes.
• B.Sc. and teaching-lab work: wet mounts of pond water and microorganisms, picking up each coverslip with the fine forceps from a Student Dissecting Set.
• Slide-preparation training before viewing on a Student Biological Microscopes unit.

Lower each coverslip at an angle to avoid trapping air bubbles, hold it by the edges, and put broken glass in the glass-waste bin.

Standard Scope of Supply

One pack contains 10 g of clear 20 x 20 mm square borosilicate glass coverslips. Microscope slides are a separate item and can be added to the same quotation, which also states the number of pieces per pack, thickness and edge finish for the batch you order.

Packing, MOQ and Lead Time

Coverslips can be quoted by the single pack or in multiples for a term of practicals across several labs. Science Lab Supplies lists packing, delivery time and price for the number of packs requested, and slides, stains or slide racks can go on that quote.

Registered with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. Send pack quantities via the contact page, build a list in the enquiry cart, or check the lab tender page for consumables tenders.

Frequently Asked Questions

What size are the Glass Coverslips for Microscopy (10g)?
Each coverslip is a clear square of borosilicate glass measuring 20 x 20 mm. They are sold by weight in a 10 g pack, and the number of pieces per pack is given on the quotation.

Why use a coverslip on a wet mount?
A coverslip flattens the drop into an even layer, holds solid material flat, slows drying and keeps liquid away from the objective lens, so the specimen stays in focus and the lens stays clean.

How should coverslips be handled and stored?
Pick them up by the edges with clean forceps, keep them dry in their packing away from chemicals and dust, and do not use chipped or cracked pieces. Dispose of broken ones as glass waste.

Who can quote these coverslips?
Science Lab Supplies quotes them from Ambala, India, giving the piece count and thickness per pack. Schools, colleges and distributors can order them together with slides and other microscopy consumables.
