Blank Cartridge - FAQs

Is there any label on the "Blank Cartridge" for the 433A peptide synthesizer (PN 400198) and if not, what happens at the bar code reader?

The blank cartridges are labeled but the label does not include the name of an amino acid. They do have a bar code. It will be read as "#29", but you may, through the Software "Dictionary", change the code assignment to correctly reflect the amino acid you are using. Any amino acid cartridge without a barcode will be interpreted as though the "pusher" has reached the position before the needles. This will stop the synthesis, as continuing could mean spraying liquid from the needle onto the instrument guideway and other surfaces. This is a safety over-ride, and occurs with either "yes" or "no" selected for the barcode reader interrupt feature.
