Application

There are no set rules in the application of the Stomacher
as a guide only and not to restrict laboratory technique.
5.1.1

Bag Selection and Filling

For best results it is recommended that only genuine Seward Stomacher
frozen foods should not harm the bags but hard particles such as bone, grit, fruit-stones and seeds
may cause puncturing. Where a marginal condition exists or any hazardous material is being
blended it is recommended that two bags are used one inside the other.
If required, several bags may be processed simultaneously providing the total volume does not
exceed 80 ml. When doing so, it is recommended that they be layered vertically so that the 'load' is
fairly evenly distributed over the paddle faces.
For volumes greater than 80ml, an alternative Stomacher

Speed Selection

The NORM. (normal) speed is suitable for the vast majority of applications and the instrument will
always set automatically to that position upon powering up. If an alternative speed setting is desired
this may be selected either prior to or during operation of the instrument. When depressed a short
signal will be heard and the corresponding small indicator lamp at the top corner of the touch pad
will illuminate.
The LOW speed may be more suitable for delicate work e.g. cell separation to reduce or avoid cell
damage. Use of the HIGH speed can provide better agitation when blending predominantly liquid
substances possibly reducing the processing time. In the event of the power being interrupted the
speed setting will always revert to NORM.
