A paraffin wax dispenser in a laboratory is primarily used for the precise and efficient dispensing of molten paraffin wax, which is essential in histology and pathology labs. These dispensers are crucial for embedding tissue samples in paraffin wax, a process that preserves and supports the tissue for sectioning and microscopic examination. The dispenser maintains paraffin wax at a consistent, optimal temperature, ensuring it remains in a liquid state for easy handling. This is vital because paraffin wax solidifies at room temperature, and maintaining it in a liquid form prevents frequent reheating, which can degrade the wax quality. In histological procedures, after tissue samples are fixed and dehydrated, they are infiltrated with paraffin wax. The dispenser allows technicians to pour the molten wax into embedding molds containing the tissue samples. Once the wax solidifies, it forms a block that can be easily sliced into thin sections using a microtome. These sections are then mounted on slides for staining and microscopic analysis. The use of a paraffin wax dispenser enhances workflow efficiency, reduces the risk of contamination, and minimizes wax waste. It often features a heated reservoir, a spout or nozzle for controlled dispensing, and sometimes a heated work surface to keep molds warm during the embedding process. This equipment is indispensable in laboratories focused on tissue analysis, enabling accurate and reliable preparation of samples for diagnostic and research purposes.
