Lab Safety Supply Inc 20F849 Microscope Slides Borosilicate Glass 72 Pack
A pack of 72 borosilicate glass microscope slides measuring 75 mm by 25 mm with ground edges at 45 degrees
- Product typeAssortments & Kits
- Borosilicate glass resists thermal shock with 90 x 10-7/°C expansion
- Ground 45° edges prevent cuts during slide handling
- 72 slides per pack supply high-volume microscopy work
- 1 mm thickness fits standard microscope stage clips
- Refractive index 1.52 delivers clear bright-field imaging
Microscope Slides Borosilicate Glass 72 Pack
These microscope slides are made from borosilicate glass and come in a pack of 72. Each slide measures 75 mm in length and 25 mm in width with a thickness of 1.1 mm. They are designed for laboratory use and general microscopy applications.
Ground Edges and Optical Clarity
The slides feature ground edges at a 45-degree angle for safer handling during preparation. A refractive index of 1.52 provides clear optical performance for accurate viewing. The material withstands temperatures from 20 to 350 degrees Celsius without damage.
Suited for Routine Lab Work
This pack suits educational settings, clinical labs, and research facilities needing standard-sized slides in bulk. Buyers requiring slides with pre-applied coatings, frosted ends, or non-standard dimensions should look at other options.

Questions about this item
How many slides in the 72-pack will need replacing if they chip or break during routine handling?
The pack contains 72 individual borosilicate glass slides; any that chip or break can be replaced slide-for-slide from the same box.
At what temperature does the glass itself reach its maximum operating limit during continuous use?
The borosilicate glass is rated to a maximum operating temperature of 350 °C, which is the first thermal limit the material encounters.
How much heat does each 75 mm × 25 mm × 1.1 mm slide absorb when left on a 350 °C stage all day?
With a coefficient of thermal expansion of 90 × 10⁻⁷/°C and an elastic modulus above 7 × 10⁴ MPa, the thin glass reaches thermal equilibrium quickly and adds negligible load to the stage heater.
