Precision Sealing for Reliable Fluorescence Imaging
Nail polish was never made for microscopy. Its solvents can leach into your mounting medium, distort fluorescence and damage delicate samples. After hours of staining and imaging prep, you deserve a sealant that won’t silently sabotage your work. CoverGrip™ protects your signal so your data stays true.
CoverGrip™ delivers a clear, durable seal for wet-mounted coverslips without fluorescence interference. Formulated with microscopy-safe ingredients, it prevents leaching, preserves signal integrity and replaces nail polish for high-quality imaging.
Key Features
- Engineered to protect fluorescence signals
- Clear, hard, durable seal that stays stable over time
- No leaching into aqueous mounting medium
- Kinder to delicate samples than nail polish
- Fast drying for smoother workflows
- Clean d-limonene formula with a gentle citrus scent
- Available in lab-friendly 15 mL and 100 mL formats
CoverGrip™ vs Nail Polish
| Feature | CoverGrip™ Coverslip Sealant | Nail Polish |
|---|---|---|
| Fluorescence Safety | No leaching or signal disruption | Can leach and distort fluorescence |
| Specimen Integrity | Gentle and microscopy-safe | Harsh solvents can damage samples |
| Seal Quality | Clear, durable, stable | Shrinking, cracking or leaching over time |
| Drying Time | Fast, smooth workflow | Often needs overnight drying |
| Purpose | Designed for microscopy | Not intended for scientific imaging |
