50pcs Slides 1.2mm Thick and 100 Pcs Cover Glass Biological Microscopes
The package includes 50 rectangular microscope slides and 100 cover glasses for biological specimen preparation.

Product Overview
The package includes 50 rectangular microscope slides and 100 cover glasses for biological specimen preparation. Slides are made of clear glass with ground edges, measuring 25.4mm x 76.2mm and 1mm to 1.2mm thick. Cover glasses are 20mm x 20mm with a thickness of 0.13mm to 0.17mm. Both are used to mount, flatten and protect specimens for clear optical observation under a biological microscope.

Key Benefits
- Rectangular slides with ground edges reduce the risk of cuts during handling
- 1mm to 1.2mm thickness ensures flatness and compatibility with standard microscope stages
- Clear glass slides provide good light transmission for high contrast imaging
- 20mm x 20mm cover glasses flatten specimens and reduce glare under the objective
- 100 cover glasses per box support repeated specimen preparation in teaching or lab use
- Standard sizes match common microscope stage clips and objective working distances
Application Scenarios
- Preparing biological tissue sections for classroom demonstration under a biological microscope
- Mounting blood smears or cell cultures in a clinical or research laboratory
- Creating temporary slides for student practical sessions in biology teaching labs
- Supporting routine specimen mounting in university or school laboratories
- Maintaining consistent sample flatness and optical clarity during repeated inspections
Who It Is For
- University and school biology teaching laboratories
- Clinical and veterinary diagnostic labs
- Research labs conducting histology or cytology work
- Students and educators preparing classroom specimens
- Quality control labs in pharmaceutical or biotech settings
Problems It Solves
- Unfinished or sharp-edged slides can damage specimens or injure users during handling
- Thin or uneven slides cause focus drift or image distortion under the objective
- Lack of cover glasses leads to specimen drying, contamination or uneven surface reflection
- Inconsistent slide thickness causes focus issues across different samples
- Low light transmission in poor-quality glass reduces image clarity and contrast
Technical Features
- Rectangular shape with precise 25.4mm x 76.2mm dimensions for standard stage fit
- Ground edges on slides to prevent finger cuts and improve handling safety
- 1mm to 1.2mm thickness ensures flatness and compatibility with standard microscope objectives
- Clear glass material with high light transmission for consistent optical performance
- 20mm x 20mm cover glasses with 0.13mm to 0.17mm thickness to flatten specimens and reduce glare
- Cover glasses protect specimens from drying, contamination and mechanical damage

Comparison With Other Options
| Plastic slides and cover glasses | Glass slides offer better flatness, higher light transmission and greater durability under repeated use and cleaning. |
|---|---|
| Slides with unground edges | Ground edges reduce the risk of cuts and improve handling safety during specimen preparation. |
| Cover glasses with inconsistent thickness | Controlled 0.13mm to 0.17mm thickness ensures consistent optical performance and prevents focus shift. |
Use Guide
- Always handle slides with clean hands or gloves to avoid oil or residue on the surface
- Place the specimen on the slide before adding the cover glass to avoid air bubbles
- Use a single cover glass per specimen to maintain consistent thickness and focus
- Clean slides and cover glasses with ethanol after use to prevent residue buildup
- Store in a dry, dust-free environment to prevent contamination between uses
