DVH Vessel Care (709-DS)
The DVH vessels have been designed for use exclusively with the
Agilent 709-DS Dissolution Apparatus. The vessel was engineered to be
easily substituted with another DVH vessel should it become
accidentally broken or damaged during use. The vessel utilizes a Noryl
collar and a PVC coating to properly align the vessel within the 709-DS
as well as protect the electronic components. Although these materials
have excellent thermal, electrical and chemical resistance; exposure to
harsh organic liquids and temperatures above 55°C should be avoided.
All electrical contact surfaces are gold plated to provide excellent
corrosion resistance.
Your DVH vessel is highly water resistant, meaning it may be cleaned
with routine manual glassware cleaning procedures and allowed to dry.
Similar to water resistant watches or electrical devices this does not
mean it is waterproof which means the vessel should not be deeply
submerged, pressure washed or undergo extended submersion for
greater than 30 minutes.
Do not wash 709-DS vessels in a dishwasher. The connectors should
be kept as dry as possible at all times. If the connectors become wet
during hand washing, or have been submerged for longer than 30
minutes, it may be necessary to allow them to dry prior to use.
DVH vessels (709-DS) require extra care when rinsing. Ensure the
vessel plate and attachment clips are dry and free from any debris before
re-inserting the vessel.
