Microscope Cover Slips 22x22mm Deltalab EUROTUBO — Box of 200

Cover slips are thin square pieces of glass placed over a specimen once it has been spread on a microscope slide. They hold the preparation in a thin, flat layer, slow down evaporation and keep the objective lens from touching the sample. The EUROTUBO range by Spanish manufacturer Deltalab uses clear, clean and degreased glass so the image stays sharp under the microscope. This model measures 22 x 22 mm, is 0.145 mm thick and comes in a box of 200 pieces.

Key features

  • Clear optical glass — clean and degreased, with no haze or greasy residue to distort the image.
  • Thickness 0.145 mm (±0.015 mm) — within the No. 1 thickness range, compatible with the standard objectives of school and laboratory microscopes.
  • 22 x 22 mm square format — the most widely used size for general microscopy and wet mounts.
  • Desiccant ball inside the box keeps the cover slips dry so they separate easily.
  • Vacuum-packed in a tropical pack with a scissor-free opening system.
  • Redesigned sturdy box that reduces the risk of breakage and closes securely after opening.

Where they are used

  • School biology labs — observing plant and animal cells, protozoa, crystals and micro-organisms.
  • University and research laboratories — wet mounts and permanent preparations.
  • Diagnostic and veterinary laboratories — routine microscopic examination.
  • Histology and cytology — covering sections after staining.

Mounting tip: To avoid air bubbles, rest one edge of the cover slip against the edge of the drop at roughly 45° and lower it slowly with a needle or forceps. Always handle cover slips by their edges — fingerprints on the surface show up under the microscope.

Frequently asked questions

How many cover slips are in the box?

The box holds 200 pieces of 22x22 mm cover slips, together with a desiccant ball that keeps the glass dry down to the last slip.

What does the 0.145 mm thickness mean?

It is the thickness of glass sitting between the specimen and the objective lens. The 0.145 mm (±0.015 mm) value falls within the No. 1 thickness class (0.13–0.17 mm), the standard for most school and laboratory microscopes. Objectives are optically corrected for this thickness, which is why using the right cover slip gives a sharper image, especially at high magnification.

Do they fit any microscope slide?

Yes. 22x22 mm cover slips fit any standard 76 x 26 mm microscope slide, the established laboratory size.

Can they be washed and reused?

They are single-use consumables. Because the glass is so thin it breaks easily during cleaning, and residues of sample, stain or detergent will interfere with later observations.

How should they be stored?

In a dry place, with the box closed and the desiccant left inside. Humidity makes the cover slips stick together, which increases breakage when separating them.
