 |
Standard
Screw Thread Finish
"T"
= Outer diameter of the thread
"E" = Inside diameter of the thread
"ID" = Inside diameter
"S" = Start of thread
"H" = Distance from top of finish to shoulder for
closure clearance |
Standard
Crimp Seal Finish
"T"
= Outer diameter of seal
"E" = Crimp tool and robotic arm clearance
"ID" = Inside diameter
"A" = Crimp seal thickness
"H" = Distance from top to shoulder for crimp and
robotic arm clearance |
Screw Thread Finishes
GPI refers to the "Glass Packaging Institute"
The
GPI is responsible for establishing and issuing standards
for the types and finishes produced by American glass
manufacturers.
For
example, an 8-425 neck finish is approximately 8mm in
diameter across the outside of the threads.
The
425 represents the finish (style of thread). |
Typical GPI finishes found in the chromatography
field are as follows:
8-425
Closure - Varian, Shimadzu
10-425 Closure - Waters Alliance 2690
13-425 Closure - Waters 48 position WISP™, Shimadzu
Note:
9mm thread finish does not appear in the GPI finishes.
It is not a standard finish. The 9mm closure and vial are
used with Agilent equipment. |
Glass
Technical Information
Terminology
Borosilicate - A glass that is high in silicate and having at least
5% boron oxide.
Linear
Coefficient of Expansion - Fractional change
in length of glass per degree change in temperature.
Strain
Point - Maximum temperature to which glass should
be heated during use.
Types
of Glass
USP
Type - Pharmaceutical glass containers can be
classified as USP Type I, II, III or NP. |
Type
I - Borosilicate glass represents the least reactive
glass.
Type I glass has the least pH shift. (Lowest leaching characteristics)
Coefficient
of Expansion = 33 or 51 for Clear and 51 for Amber
Type
II - is de-alkalized soda lime glass with higher
levels of sodium hydroxide and calcium oxide.
Type
III - soda lime glass - cannot be autoclaved.
Type
NP - general purpose soda-lime glass used where
chemical durability and heat shock are not factors.
Coefficient
of Expansion = 92 |
