CoverGrip™ Coverslip Sealant is the first product specifically designed for sealing the edges of wet-mounted coverslips for fluorescence microscopy. Unlike nail polish, CoverGrip™ contains no ingredients that can leach into aqueous mounting medium and affect specimen fluorescence. CoverGrip™ is made with d-limonene, a natural, environmentally-friendly solvent with a pleasant citrus aroma, and dries to form a clear, hard, durable seal along the edges of the coverslip. Available in 15 mL brush-cap applicator bottles (23005) or in 100 mL dropper-cap refill bottles (23005-1) .
