High quality D263 coverslip glass is essential for microscopy and imaging. Small diameter coverglass with diameters ranging from 3 to 8 mm are now available in convenient packages of 100.
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.
