Microscope Slides and Cover Glass for Microscopy and Pathology
Slides and cover glass are the base consumable for every microscopy and pathology workflow, from routine smears to immunohistochemistry. This category covers plain, frosted and charged slides plus cover glass in the coverslip sizes and thicknesses that match common objectives and mounting methods.
Slide and Cover Glass Formats Stocked
- Plain microscope slides - 25 x 75 mm and 3x1 inch clear glass slides with cut, ground or beveled edges, for wet mounts and general microscopy.
- Frosted slides - Single- and double-frosted slides with a writing area for pencil or marker labeling, in white and colored frost for specimen sorting.
- Positive-charged slides - Charged slides with a treated surface that binds tissue sections and cytology preparations for immunohistochemistry and adhesion-sensitive staining.
- Cover glass - Square and rectangular cover glass from 18 x 18 mm to 24 x 60 mm in No. 1 and No. 1.5 thickness, in corning-style boxes for mounting and coverslipping.
- Specialty slides - Concavity (well) slides, adhesion-coated slides and thick slides for specific mounting and manual staining methods.
Slide and Cover Glass Comparison
| Format | Common Size | Feature | Typical Use |
|---|---|---|---|
| Plain slide | 25 x 75 mm | Cut or ground edge | Wet mounts, general microscopy |
| Frosted slide | 25 x 75 mm | Writing area | Labeled smears, routine staining |
| Positive-charged slide | 25 x 75 mm | Treated surface | IHC, cytology adhesion |
| Cover glass No. 1 | 22 x 22 mm | 0.13-0.17 mm | Standard coverslipping |
| Cover glass No. 1.5 | 24 x 50 mm | 0.16-0.19 mm | High-magnification imaging |
Charged Versus Plain Slides and Coverslip Thickness
Plain slides cover wet mounts and routine microscopy. Positive-charged slides carry a surface treatment that electrostatically binds tissue sections and cytology cells, which reduces section loss during aggressive staining and immunohistochemistry.
Slides and cover glass are consumed by the case in any pathology or cytology operation, with charged slides turning over fastest in immunohistochemistry programs. Standing orders on frosted and charged slides and standard cover glass keep the grossing and staining benches supplied. Order at the best Wholesale Prices with MAP Medical.
Frequently Asked Questions
What is the difference between plain, frosted and charged slides?
Plain slides are clear glass for wet mounts and general microscopy. Frosted slides add a matte writing panel for pencil or marker labeling. Positive-charged slides carry a surface treatment that binds tissue sections and cytology cells, which prevents section loss during immunohistochemistry and aggressive staining. Labs stock all three by workflow.
What is the difference between No. 1 and No. 1.5 cover glass?
Cover glass is graded by thickness. No. 1 is roughly 0.13 to 0.17 mm and covers routine coverslipping. No. 1.5 is roughly 0.16 to 0.19 mm and matches the design correction of most high-magnification and oil-immersion objectives, giving sharper images. Both are stocked across the common square and rectangular sizes.
What cover glass sizes are stocked?
Cover glass is stocked in square sizes such as 18 x 18 mm and 22 x 22 mm and rectangular sizes up to 24 x 60 mm to match slide coverage and specimen size. Size selection depends on the mounted area and coverslipping method. Each product page lists the size and thickness grade.
Can hospitals and labs order microscope slides and cover glass in bulk?
Yes. Microscope slides and cover glass are stocked in case quantities for pathology and cytology labs, hospital and reference labs, and research facilities. Standing orders cover the highest-volume SKUs, including positive-charged slides, double-frosted slides and No. 1.5 cover glass. Contact our procurement team for tiered case pricing and standing order setup.
What slide and cover glass should a laboratory stock on its formulary?
A working slide and cover glass stock list typically includes plain slides for wet mounts, frosted slides for labeled routine staining, positive-charged slides for immunohistochemistry and cytology, and cover glass in both No. 1 and No. 1.5 thickness across the sizes the workload requires.
