DPX Mountant- 250gm Packs

DPX Mountant is a synthetic resin-based mounting medium widely used in microscopy and histology to preserve stained specimens on glass slides for examination and long-term observation. The name DPX refers to a formulation traditionally containing distyrene (polystyrene resin), a plasticiser, and xylene. This mounting medium forms a transparent layer between the specimen and coverslip, helping maintain specimen visibility and preserve staining characteristics. Its optical properties support microscopic examination of appropriately prepared biological and histological sections. DPX Mountant is commonly used in histopathology, cytology, teaching laboratories, and research facilities, particularly for preparations stained using haematoxylin and eosin and other compatible staining methods. It is a ready-to-use liquid rather than a single pure chemical compound, so its composition, viscosity, drying behaviour, and safety characteristics depend on the formulation. Lab Wale offers DPX Mountant in 250 gram packs for suitable microscopy, educational, and research laboratory applications.

Key Features of DPX Mountant

• Transparent mounting medium: Forms a clear mounting layer that allows light to pass through appropriately prepared specimens during microscopic examination.
• Synthetic resin formulation: Traditionally combines a resin, a plasticiser, and an organic solvent to support specimen mounting and coverslip adhesion.
• Stain preservation: Helps preserve compatible stained preparations for microscopic observation and laboratory archiving.
• Optical compatibility: Its refractive properties support examination of appropriately mounted histological and cytological specimens.
• Ready-to-use liquid: Designed for direct application in compatible mounting procedures, subject to the manufacturer’s instructions and specimen requirements.

Laboratory Applications of DPX Mountant

• Histology slide preparation: Used to mount appropriately stained tissue sections under coverslips for microscopic examination.
• Haematoxylin and eosin staining: Commonly used to mount compatible H&E-stained histological sections while maintaining specimen visibility.
• Cytology preparations: Used in suitable cytological slide-mounting procedures when the specimen preparation and staining method are compatible with resin-based media.
• Educational microscopy: Supports the preparation of permanent or long-term teaching slides for supervised practicals in biology, histology, and pathology-related subjects.
• Research specimen archiving: Used in research laboratories to mount compatible stained specimens for subsequent microscopic observation, comparison, and documentation.

Frequently Asked Questions About DPX Mountant

What is DPX Mountant used for in microscopy?

DPX Mountant is used to secure coverslips over suitably prepared and stained specimens, particularly histological sections. It forms a transparent mounting layer that helps preserve staining characteristics and supports microscopic examination. Its suitability depends on the specimen, staining procedure, and compatibility with resin-based mounting media.

What are the main components of DPX Mountant?

Traditional DPX Mountant formulations contain distyrene, a polystyrene resin, a plasticiser, and xylene as a solvent. Formulations can vary between manufacturers, including differences in plasticiser composition. The complete product is a mixture rather than a single chemical compound with one molecular formula.

Does DPX Mountant have a molecular formula or CAS number?

DPX Mountant does not have one universal molecular formula, empirical formula, or molecular weight because it contains multiple components. Some suppliers assign CAS number 130-12-2 to their DPX product, but identifiers can vary by product documentation. Confirm the identity and safety information for the specific formulation being purchased.

Can DPX Mountant be used with haematoxylin and eosin-stained slides?

Yes, DPX Mountant is commonly used for compatible haematoxylin and eosin-stained histological preparations. The specimen should be processed according to the staining protocol, including any required dehydration and clearing steps. Follow the mounting medium manufacturer’s instructions to avoid incompatibility or deterioration of the preparation.

How should DPX Mountant be stored and handled safely?

Store DPX Mountant in a tightly closed, compatible container in a cool, well-ventilated area away from heat and ignition sources. Traditional formulations containing xylene are flammable and may produce harmful vapours. Wear suitable gloves and eye protection, avoid inhalation and skin contact, and follow the applicable Safety Data Sheet and institutional procedures.

Storage Conditions for DPX Mountant

Store DPX Mountant in its original, tightly closed, compatible container in a cool, well-ventilated area, protected from direct sunlight and excessive heat. Keep it away from ignition sources and incompatible chemicals. Because many formulations contain volatile, flammable organic solvents, ensure appropriate ventilation and follow the supplier’s specified temperature range and storage recommendations.

Precautions for Handling DPX Mountant

Review the applicable Safety Data Sheet before use. Wear suitable chemical-resistant gloves, safety goggles, and protective laboratory clothing. Handle the medium in a well-ventilated area or fume hood as required to minimise exposure to solvent vapours. Keep it away from flames, sparks, and hot surfaces, avoid skin and eye contact, and collect spills and waste using approved procedures for solvent-containing laboratory chemicals.
