Click'n'goversus Pressure Lever Cassettes
Click'n'go
Cassettes
Advantages:
the Click'n'go cassette features an automatic occlusion
setting
an incorrect adjustment of the pressure lever
is not
possible
a calibrated, fatigue-proof spring guarantees
an optimum,
reproducible pressure onto the tubing independent
of the tubing diameter, material and its
condition
the pumping conditions are defined and reproducible
at any time
the occlusion remains correct during the whole service
life of the tubing
no occlusion resetting is required
optimum long-term channel-to-channel conformity
ideal for long-term and unattended operation
Limitations:
this type of cassette must not be used with the
tubing Tygon MH 2075 (use
cassette with the pressure lever)
not recommended for differential pressures above
1 bar / 14.5 psi
heavily varying differential pressure conditions may
influence the flow rate
the adjustable occlusion lever allows an individual
pressure setting for each channel
due to the various tube sizes, wall thicknesses and
materials available, an optimally adjusted occlusion
lever may offer advantages in comparison
to the Click'n'go cassette
for certain operating conditions, such as varying
and/or elevated differential pressure conditions,
this type of cassette may have advantages
over the Click'n'go cassette
preferably used for very hard tubing material, e.g.
Tygon MH 2075
Limitations:
the pressure lever must be individually
set on
each channel
for constant flow-rates it may be necessary to
readjust the pressure setting at regular intervals
the occlusion can be over-tightened
if the lever
is incorrectly set
an over-tightened tube pressure shortens
the service-life
of the tubing
the pressure lever should NOT be used
for flow-rate
adjustments. Such a "calibration" can be
instable and result in a shorter tubing life.
