Product Overview
DPX Mountant LR is a premium-grade, solvent-based mounting medium designed for creating permanent microscope slides with exceptional optical clarity. Formulated with a neutral pH balance, this non-fluorescent mountant ensures long-term preservation of stained biological specimens without yellowing or degradation over time. Its optimized refractive index (approximately 1.52) closely matches that of glass, minimizing light refraction for sharper imaging under high-magnification objectives. The medium’s controlled viscosity allows for bubble-free application, while its rapid drying properties enable efficient slide preparation without compromising structural integrity. Compatible with most histological stains including H&E, PAS, and Masson’s trichrome, DPX Mountant LR maintains stain vibrancy and morphological detail. Its hydrophobic composition prevents water absorption, making it ideal for humid Indian lab environments where moisture resistance is critical. The reagent-grade purity ensures consistency across batches, eliminating background interference in photomicroscopy applications. Unlike aqueous mountants, DPX’s xylene-based formulation provides superior adhesion to glass surfaces, preventing sample detachment during long-term storage or transportation.
FAQs
1. What is the drying time for DPX Mountant LR under standard lab conditions?
Typically dries to a hard, clear finish within 24-48 hours at room temperature (20-25°C), though initial tack-free surface forms in 2-4 hours. Accelerated drying can be achieved with gentle warmth (37°C) for 1-2 hours.
2. Can this mountant be used with immunofluorescence-stained samples?
No, DPX Mountant LR is not recommended for fluorescence applications as its solvent base may quench fluorophores. For immunofluorescence, consider aqueous mountants like glycerol-gelatin or commercial anti-fade reagents.
3. How should DPX Mountant LR be stored to maintain its properties?
Store tightly sealed in a cool, dry place away from direct sunlight and ignition sources. Ideal storage temperature is 15-25°C. Avoid freezing as it may alter viscosity. Keep container upright to prevent leakage.
4. What precautions should be taken when handling this mountant?
Work in a well-ventilated area or fume hood due to xylene vapors. Wear nitrile gloves and safety goggles to prevent skin/eye contact. Avoid inhalation of vapors, especially in confined spaces.
5. Is this mountant compatible with plastic coverslips?
No, DPX Mountant LR is formulated specifically for glass coverslips. The solvents may dissolve or deform most plastic coverslips over time, compromising sample integrity.
