Note Use of the temperature probe with corrosive samples or extreme temperatures can
cause O-rings to break down faster.

Maintenance
Check stopper gaskets and O-rings regularly for wear and replace them when necessary. The
square stopper has two gaskets and internal O-ring. The round stopper has an internal
O-ring.
A 4 mm screw (at least 3 mm long) is required to remove the liner that supports the internal
O-ring.
To replace the internal O-ring (round or square stopper)
1. Insert the 4 mm screw several turns into the stopper base, and use it to pull the liner out
of the base (leave the screw in the liner).
