All of the Glass Vials on this page are manufactured from ‘Neutral’ Glass, otherwise known as ‘Type 1’ Glass. This is Pharmaceutical grade Glass and therefore the most refined and stable Glass available. The Amber Glass Vials are available with either a Thermoset Screw Cap or a Cap,Teat and Pipette Assembly for liquid-drop dispensing. The more comprehensive range of Clear Glass Vials all come with a Screw Cap (usually Black) as standard. We also carry stock of two more specific ranges of Vial: a Snap-Neck Vial with a wide Neck to suit a Snap-on LDPE Closure and an Injection Vial to suit an injection port Crimp Closure for injectable medications or a Cork Stopper.
