Cover Glass for Hemocytometer, 10/pk

Precision-ground for accurate manual cell counting, this specialized cover glass fits standard hemocytometer counting chambers used in in vitro cell culture workflows. Unlike conventional microscope cover slips, hemocytometer cover glasses are manufactured to a controlled thickness and optical flatness, producing a defined volume above the etched counting grid so cells settle in a single, uniform focal plane during microscopy.

Each glass rests securely on the chamber shoulders of Improved Neubauer, Bürker-Türk, and similar counting slides, supporting reproducible enumeration of suspension cells, primary cultures, and viability assays such as trypan blue exclusion. The set is supplied as a pack of 10 cover glasses, providing a practical quantity for routine laboratory use, while individual pieces can be cleaned and reused between counts when handled with care.

Offered by STEMCELL Technologies as part of its cell counting accessory line, this cover glass integrates with the company's broader portfolio of hemocytometers, viability stains, and counting workflows. Researchers working with hematopoietic cells, immune cells, and cultured mammalian lines rely on a precisely seated cover glass to prevent grid distortion, fluid leakage into the chamber moat, and inconsistent chamber depth, common sources of error in manual counts.

For best results, load the cell suspension into the chamber with a pipette first, then place the cover glass gently on top so capillary action draws the fluid under the glass without introducing bubbles. The flat optical surface supports clear visualization of the etched grid at microscope magnifications of 10x to 40x, and the rigid glass withstands repeated cleaning with ethanol or mild detergent between sessions.
