The hose combinations are to be selected on the basis of the required application.
When using Micro Ubbelohde viscometers with TV sensors, the ignition temperature of the
media to be measured has to be taken into account! It has to be higher than 250 °C.
In the work mode "Press", in case of malfunction, the sample can emerge from the capillary
tube and could enter the thermostat bath! Therefore, especially during the pressing work mode, a
correct connection of the measuring tripod to the ViscoPump III and a properly used viscometer are very
important for the safe operation. With health hazardous and/or corrosive samples (e.g. acidic, toxic or
hazardous to the environment), the work mode "suction" is the preferred choice.
In the work mode "suction", the sample can be pumped into the ViscoPump in case of a
malfunction! In order to avoid this and the associated damage to the ViscoPump III, you must always
use a suitable tube kit including the safety bottles VZ 7021 or VZ 7022 during the work mode "suction".
In order review a possible immersion of the sample into the safety bottle, a capacitive sensor VZ 8552 is
highly recommended.
Description
Silicone hose kit, oppressive, for
Ubbelohde viscometers (3 legs), and
Cannon-Fenske and Ostwald viscometers
Silicone hose kit, suctioning, for
Ubbelohde viscometers (3 legs)
PTFE hose set, suction, for Ubbelohde
viscometer (3 legs)
PTFE hose kit, suctioning, with soda lime
filter VZ 7215 for Ubbelohde viscometers
(3 legs)
PTFE hose kit, suctioning, for Ubbelohde
viscometers (4 legs)
PTFE hose kit, suctioning, with soda lime
filter VZ 7215 for Ubbelohde viscometers
(4 legs)
For TC viscometers (3 and 4 legs) with
screw connections: Silicone hose fittings
with connecting cable. For oppressive
operation
Application
Standard, but please observe: the sample
can leak from the capillary tube during a
malfunction
Standard, safer than oppressive operation,
as the sample cannot leak from the
capillary tube.
Unsuitable for volatile samples.
For aggressive samples that attack
silicone, such as sulphuric acid. Hose
lengths are designed to fit the AVS
on the support console VZ 8571.
All hose sets for suctioning operation can
be combined with the suction set and the
sample fill set.
For aggressive samples whose vapors are
absorbed by soda lime filters to protect the
ViscoPump. Depending on the sample, an
active carbon filter VZ 7216 can be used
instead of the soda lime filter VZ 7215.
Hose lengths are designed to fit the
