HD-Type and HDHT-<br />
Type <strong>Syringes</strong><br />
Modern GC headspace<br />
analysis requires<br />
injecting over large<br />
temperature ranges.<br />
Conventional head<br />
space syringes on the<br />
Plunger<br />
New Compression Spring market use a rubber<br />
PTFE Plunger Tip<br />
O-ring sealed plunger<br />
which has a limited<br />
sealing performance at high temperatures. This<br />
is due to varying thermal expansion between<br />
the different materials. The high dynamic<br />
HD-Type syringe and HDHT-Type syringes<br />
employ a unique spring in the plunger tip<br />
which compensates for the materials’ different<br />
expansion coefficients, creating a superior seal<br />
over a larger temperature range, improving<br />
syringe lifetime.<br />

HDHT-Type <strong>Syringes</strong><br />
A cement-free connection between the needle<br />
and the glass barrel make HDHT-Type syringes<br />
a perfect choice for applications where<br />
temperatures up to <strong>20</strong>0 °C will be used.<br />
