Offering a timesaving and efficient solution for researchers working with limited sample volumes in automated laboratories, the Large Opening R.A.M. Vial, 12x32mm, with StepVial design are available in clear or amber Type 1 borosilicate glass with a 9 mm threaded neck finish. Providing reduced volume sample containment for automated sample handling systems the inserts are centered precisely into the recessed “step” in the neck opening of the vial, eliminating the need for metal or plastic springs. Suitable for use with robotic arm autosamplers such as those available from Agilent Technologies and others they are available with a large marking spot allowing researchers to mark vials easily with a #2 pencil or marker.
