Perform highly accurate low
temperature viscosity measurements with ISL's TLV25
system. Depending on the type of cryostat used, end
temperatures of
-30篊 (KV40) or -60篊 (KV80) can be reached. Lower
temperatures are also available upon request.
A microprocessor controlled heating
element ensures highly stable bath temperatures, even
when glassware is placed in the bath for measurement.
The setpoint can be set in steps of 0.1篊 from -90篊 to
60篊 (-130..140篎). Overall system accuracy is better
than ?.03K.
The TLV25 requires an external
cryostat. To maintain a stable temperature, the cryostat
must be capable of cooling 25 liters of liquid 5篕 below
the setpoint temperature. The following cryostats are
recommended and available from ISL as optional
equipment:
- KV40 Cryostat: enables cooling to -30篊
- KV80 Cryostat: enables cooling to -60篊 |
