Valves for vials
The screw-cap Mininert is available in a variety of sizes. The
crimp-top valve for 13 mm ID glassware slides into the neck
of the vial and features a threaded flange which is turned to
provide a leak-tight fit.

Valves with threaded fittings
Our threaded designs offer positive on/off fluid control as
an in-line valve or syringe access as a termination valve at
a sample point. In-line valves are 1/4-28 male to male or
1/4-28 female to female. Termination valves are offered in
1/4-28 male or female and 1/8" NPT male or female.

Mininert syringe valves
These convenient add-on valves allow our Series C and D
syringes to store samples at up to 250 psi. The valve body is
all PTFE, with a stainless steel stem. Also available to fit luer-
tip syringes from any manufacturer. All accept traditional
luer needles.

Mininert Valves
Mininert push-button valves are
highly dependable, leak-tight
closures for screw-cap vials and
other laboratory containers. When
used with a glass vial, only PTFE
and glass are in contact with the
contents. Their unique features make
Mininert valves the ideal closure for
specs
Temperatures
Mininert valves can be
used at temperature up
to 105°F. However, after
use at high temperatures,
the valve may leak
slightly when cooled
to room temperature.
Materials
PTFE is highly inert and
may be used with most
common materials. It is
particularly useful for
working with most acids
and organic solvents.
However, problems may
be encountered when
used with organometallics
and some strong bases.
We recommend actual
exposure tests before
use with any material.
Pressure
The sealing ability of
Mininert valves is more
than adequate for con-
taining most volatile
liquids and gases at
low pressures. Mininert
valves have been used as
high as 120 psi without
leakage, but this is

a recommendation
for pressurizing glass
containers to these levels.
Such pressurization of
glass containers can be
extremely dangerous.
calibration standards, air- or moisture-
sensitive fluids, derivatizing reagents,
or volatile chemicals. Operation is
extremely simple – push the green
button to open the valve, insert the
needle through the septum and take
a sample, withdraw the needle, and
push the red button to close the valve.
