In addition, a sample line holder (shown in the following figure, on top of the magnet), a spare
parts kit and documentation are provided. Refer to Connecting the Transfer Line Holder
[}24] for instructions on how to install it.
Figure4.2: Recommended Laboratory Setup
The glass flow tube with flow tube protector and flow interface are shown in the figure Figure
4.3 [}17].
The 5 mm NMR glass flow tube together with the tube holder, which has the shape of a
spinner, is compatible with any standard Bruker 5 mm NMR probe with insertion depth of 20
mm. The InsightMR glass flow tube volume corresponds approximately to the active volume
of a standard 5 mm tube.
The transfer line is composed of 2 sample lines, sample in and sample return, and 2
concentric temperature control lines surrounding the sample lines. Thermostatic liquid is
flushed through the temperature control lines to maintain the temperature during the sample
transfer to the NMR and back. Insulating foam around the transfer line prevent temperature
loss, condensation and injury through high temperatures.
The recommended laboratory set up is shown in the figure Figure 4.2 [}16]. The pump and
the thermostat can be purchased together with InsightMR, as options. They are not included
as default.
The reaction mixture is pumped from the vessel, through the pump, the valve (flow interface)
and the sample lines, to the NMR and back. Tubing and standard HPLC fittings are provided
to connect the vessel to the pump, the pump to the valve and the valve back to the reactor.
The temperature control line inlets and outlets are fixed to the flow interface, which can be
secured to a laboratory stand.
