Installation
Two 6 mm Swagelok water connections are provided. Although it is not critical, it is
preferred that the inlet water be applied to the axial Swagelok fitting and the water
outlet to the radial fitting.
The water temperature should about 20
o
C but above the dew point for the environ-
ment in which the evaporator is used. A flow of at least 0.5 litre/minute is required.
3.2 Linear Motion Thimble
IMPORTANT
Check that the countersunk mounting screws are not loose and that they are well
seated into their countersunk holes, or the thimble mechanism will catch on them.
The linear motion thimble is a precision mechanism and should always be turned slowly
and gently by hand. At no time should excessive force be used. The total thimble mo-
tion is 50 mm. When fully compressed the ends of the knurled grip are no more than
half way across the heads of the M3 countersunk mounting screws. The fully extended
position is 25 mm further back than this.
The end stop in the compressive direction is in the evaporator. The end-stop in the ex-
tensive direction is built into the thimble. The end-stops should not be used as a matter
of routine. They are there only for “last resort” protection of the bellows.
The instrument may be put out of alignment or damaged if the end-stops are hit
too hard.
3.3 Mounting rods and crucibles
To mount crucibles or rods
(1) Drive the thimble so as to bring the molybdenum rod holder backwards far
enough to give access to the screws and mounting hole.
(2) Insert the crucible or rod. Rods can be up to 55 mm long allowing for 5mm in-
sertion length in the rod holder.
