Xtra clean conical cap
This item is ideal for a vial cap for washing/cleaning solvents. The septa-less structure ensures that the cleaning solvent is not
contaminated by the septum, making it safe to use for long-term multi-sample analysis.
Acts like a septum but without the actual “septum”. This septum-free cap prevents elastomer-based contaminants from entering the wash
solvent, while reducing the rate of solvent evaporation.
