3.3.4 Fitting the needle or tubing
22 PEEK needle (6.1835.010) or PEEK tubing (6.1835.020 /
6.1835.040 / 6.1835.050)
23 Needle holder
24 PEEK pressure screw (4.766.4320 or 6.2833.020 +
6.2744.080)
25 PEEK pressure screw (6.2744.010)
26 PTFE capillary (6.1803.070 or 6.1831.050 / 6.1831.060 /
6.1831.080)
When using a 6.1835.xxx PEEK tubing, do not use any
stoppers on the sample vessels since these cannot be
pierced by the tubing and this would damage the PEEK tub-
ing!
With PEEK needles
perforated stoppers can be used.
