VT setup

CryoProbe Installation BRUKER 51 (93)

CAUTION: Do not interrupt the VT unit or its gas flow at any time while the

CryoProbe is cold. The sample may cool down to very low temperatures, poten-

tially breaking the sample tube upon freezing or damaging the substance under

investigation. Moreover, only a constant dry gas flow will avoid water condensa-

tion inside the CryoProbe.

NOTE: Damages of this kind are not covered by the warranty. B

RUKER is not li-

able for destroyed samples due to disregard of the instructions given in the Cryo-

Probe documentation.

Table 3.13. VT setup

step action

v.1 Connect the VT gas inlet of the CryoProbe either directly to the VT unit

or to a BCU05 gas cooler but do not switch the BCU05 O

N yet.

CAUTION: When cold operation has been started, the VT gas supply

must not be interrupted before the CryoProbe has been warmed-up

again. Thus, a BCU05 gas cooler can only be inserted while the Cryo-

Probe is warm.

v.2 Set the VT gas flow rate and VT heater power limit according to the

values given on the specific L

IMITATIONS - WARNINGS sheet of the Cryo-

Probe. Do not switch the VT heater on yet.

NOTE: A high VT gas flow rate is recommended but it must not lift the

sample.

v.3 Verify that there is no sample in the magnet yet.

v.4 Configure the VT unit for the Pt100 temperature sensor with edte.

Make sure the Pt100 sensor cable is connected properly at CryoProbe

and VT unit.

NOTE: An optional B-TO2000 unit for conventional probes uses the

same type of Pt100 cable. The cable is suitable for the CryoProbe and

there are no special considerations when using a B-VT3000. A B-

VT2000, however, cannot be toggled properly from B-TO2000 to Cryo-

Probe operation with edte (although no error occurs); it must be set

explicitly at its E

UROTHERM module. With a B-TO2000, the EUROTHERM

would be set neither for a Pt100 (code 0225) nor for a Cu/Const thermo-

couple (code 0203) but with the special code 5203. When using a Cryo-

Probe, make sure the E

UROTHERM is configured for Pt100 with code

0225. See the B-VT2000 Operating Manual (P/N W1101034) for instruc-

tions.

v.5 Set the sample temperature to somewhere above room temperature,

e.g. 300 K.

v.6 Switch the VT heater on.

v.7 Wait until the ‘sample’ temperature and the heater power in the edte

window settle.
