A PL Reagent Reservoir is a laboratory container used to hold and dispense liquid reagents during pipetting procedures. It is commonly made from high-quality, chemical-resistant plastics like polypropylene (PP) or polystyrene (PS). The reservoir features a wide opening for easy filling and a V-shaped or tapered bottom that ensures minimal liquid wastage. Many models include graduated markings for approximate volume measurement and are compatible with single and multichannel pipettes. Available in sterile and non-sterile types, it supports various laboratory applications. Reagent reservoirs are lightweight, easy to handle, and improve efficiency, accuracy, and cleanliness in routine laboratory workflows.
