The new Interlocked™ Vial is composed of a glass vial and a clear glass insert fused together, thus eliminating any movement of the insert and concerns about contaminants around the fused seam/space between the neck of the vial and the insert.
Glastic is a unique combination of Type I low extractable borosilicate glass insert and a clear or amber thermoplastic polymer outer vial shell. The glass is the only contact between the sample and the seal.
The ID design of the J.G. Finneran R.A.M.™ Vial incorporates the Step Vial feature that precisely centers a limited volume inert in the vial neck. The flanged conical insert will only work in the Finneran vial.
