Coverslip/Coverglass

High quality coverslips glasses are essential for microscopy and imaging. 
Small diameter coverglasses with diameters ranging from 3 to 8 mm are now available from stock in convenient packages of 100.

  • 3 mm round in #0 or #1 for cranial window technique
  • Available in #0, #1, #1.5 and #2 thickness
  • Round, square, and rectangular geometries
  • High tolerance versions available
  • Ships from stock for fast delivery
Coverslip Glasses

For microscopy at higher resolutions (e.g., 40X, 60X or 100X), choosing the correct coverslip thickness is critical to good image resolution.

Warner's line of German borosilicate glass include coverslips at #0, #1, #1.5 and #2 thickness. We also offer high tolerance (thickness) coverslips in several popular sizes.

Coverslip glasses in most geometries and thickness are stocked in depth, especially the sizes used with Warner chambers. Coverslip glasses are shipped from stock in convenient packages of 100 (unless stated otherwise). Consult the Specifications tab to select the correct coverslip/coverglass for your chamber and application.
