Needles made of zirconium oxide or PEEK can be used for removing sam-

Warning
When a sample tube 6.1835.050 or a blunt PEEK needle is used, no
stopper is permitted to be used on the sample vessels. These stoppers
cannot be penetrated by such needles. The needle could become dam-
aged if this is attempted! Perforated stoppers can be used with dou-
ble-bevel needles.
