The removable water bath connects directly to the inlet and outlet of the heater /
circulator. Following are the connection procedures for the VK 7025 Dissolution
Apparatus:
Step 1. Ensure the water bath is positioned under the vessel plate and rests
firmly on the base plate. Secure the vessel plate to the frame with three
screws. Finger-tighten the screws. overtightening the screws could
damage the vessel plate.
Step 2. Locate the two tubing clamps.
Step 3. The heater / circulator has two liquid ports, one on each end. The inlet is
connected to the water bath outlet and the outlet (which is located next
to the power switch) is connected to the water bath inlet.
Step 4. Slip a tubing clamp over one end of the short length of tubing that is
connected to the underside of the water bath. Carefully place this end of
the tubing over the inlet port on the heater / circulator. Slide it on until it
meets the heater / circulator.
Step 5. Slide the clamp toward the end until it is over the inlet port and secure.
This ensures a leak-free connection.
Caution
Do not overtighten the tubing clamps. Damage to the plastic
tubing could result.
