the corresponding seals. The adapter seals have to be exchanged regularly. The corresponding
spare parts are listed in section 10.3.
NOTE
Overtightening the lock nuts on the conical adapters of the vacuum cover and sample tubes will
scarcely remedy a leak problem, but would decrease the lifetime of the parts. The problem is more
readily solved by checking the quality of the corresponding seals, i.e. the adapter seals and/or the
conical O-rings.
NOTICE
Risk of thread damage by overtightening
• Do not use a wrench with a long lever arm when exchanging the conical adapters due to
physical or chemical damage
