Frequently Asked Questions

What does "#1 thickness" mean for this cover glass?

No. 1 thickness corresponds to roughly 0.13–0.17 mm, the most common range for standard objectives. It matches the cover-slip correction on most routine brightfield and phase-contrast lenses, giving sharp focus without spherical aberration.

How many cover slips come in each box?

Each box contains 10 individual 1 oz. vacuum packs, for 10 oz. of cover glass total. Vacuum packing limits moisture exposure and helps separate slips cleanly at the bench.

Are these cover slips sterile?

No. These are supplied non-sterile for general microscopy, histology, and teaching use. If a sterile field is required, autoclave or sterilize them per your laboratory's validated protocol before use.

Are 18x18 mm slips suitable for hemocytometer counting?

Yes. The 18 mm x 18 mm square format covers standard counting chambers and is well suited to wet mounts and cell counts. The uniform #1 thickness supports consistent fluid-layer depth across the chamber.
