4. Locate the DrySyn MULTI base plate on a hotplate stirrer (Maximum

hotplate diameter 145mm).

5. Select the appropriate size of inserts for the flasks being used and carefully

place them into the base plate, if you are only doing 1 reaction, use the

central position for optimum stirring.

6. If available place the hotplate stirrer's temperature probe into the 3.5mm

hole in one of the inserts.

INSPECT YOUR GLASSWARE

Please ensure your glassware is free of star cracks. Flasks can become significantly

weakened around the perimeter by etching which occurs when the flasks are poorly

loaded into glass washers. Please be aware that glassware with etching should not be

used in the DrySyn.

ENSURE YOUR FLASK FITS PROPERLY

When selecting a flask, firstly ensure that the flask fits correctly by rolling it around in the

insert. If the flask feels tight, or scratches the side of the DrySyn, or feels like it is sitting on

an edge, the flask may be too big. Choose another flask. The DrySyn is manufactured to

0.2mm larger than the flasks supplied by Quickfit and Duran, please refer to the chart

below.

Select a long thin stirring bar for optimum stirring. Carefully place the stirring bar

into round bottomed flask. Do not drop stirring bars into the flask as this can cause

breakage!

CLAMP YOUR FLASK SECURELY AT THE NECK

Although the flask is supported from beneath, it is also advised to clamp the neck to stop

the flask from tilting. If using a condenser, it is essential to support the flask with a clamp to

hold the weight of the condenser and reduce the pressure on the flask.
