By combining a wide mouth with a tapered neck, the Versa Vial, by J.G. Finneran Associates, simplifies the task of routinely preparing samples for autosamplers. The vase-like neck design of the Versa Vial has a 9mm opening, which is the largest target opening area available for any autosampler vial. With this unique design, it is easier to add samples to the vials using a pipette, and safer to empty the vials. Problems generally associated with crimping and decapping, such as cracked necks and dangerous sharp edges from aluminum seals, are eliminated. The elongated pick-up area in the neck accommodates variations in the robotic arm settings allowing this vial to be used with most autosamplers, including Agilent, CTC, Finnegan, PerkinElmer, Varian, and the Waters Alliance instruments.
The 12×32 mm Versa Vial is available in clear or amber Type I borosilicate glass, or polypropylene, which is ideal for ion chromatography applications. The vials can be sealed with either a 12 mm polyethylene plug, PTFE/silicone plug or a chlorobutyl/siliconized plug. The polyethylene plug has a conical starburst design that eases autosampler needle penetration, and an extended tab to simplify plug insertion and removal. The softer PTFE/silicone and chlorobutyl/siliconized plugs press-fit securely into the neck opening and are autoclavable.
