Operation Sbh Conc/1 - Stuart SBH CONC/1 Instructions For Use Manual

To insert the needles, press each needle firmly, pointed end first, through the relevant guide hole with enough
pressure to pierce the sealing membrane behind. The gas chamber membrane is self sealing so needles can be
removed and replaced several times. Only use needles where samples will be placed or gas will be wasted.
Replace the gas chamber onto the carriage and tighten via the locking nut.

Operation SBH CONC/1

Use the carriage handle to raise the needles to the highest point away from the block heater, insert your sample
test tubes into the block heater. Carefully lower the needles into your sample tubes, using the carriage handle.
Position the needles at the required height above the liquid surface, take care not to lower the needles into your
samples. Set the block heater to the desired temperature and switch on the gas supply, taking care not to exceed
2 psi. To further speed up evaporation, the height of the needles can be gradually lowered as the sample volume
reduces. On completion switch off the gas flow and raise the chamber out of the way. Take care the needles may
be hot at this point. Operation of your Stuart block heater will be detailed in the manual supplied with it, if further
copies are required these can be downloaded at www.barloworld-scientific.com.
