2 independent reaction vesselsthe tribute™´s reaction vessels are completely independent.  synthesize any 2 peptides simultaneously at different scales and using different programs for each cycle!101 unattended couplingsthe tribute™´s amazingly compact amino acid rack can perform over 100 couplings without reloading!  perfect for long peptide synthesis.click here for video of amino acid rackfull-color chemical-resistant touchscreencompletely revolutionary, this cutting-edge feature makes software operation a snap, and with no external computer, the tribute™ saves you valuable lab space as well!click here for videoflexible fluid delivery (top-down or bottom-up)the tribute™ is completely flexible.  choose top-down or bottom-up deliveries depending on the properties of your reagent.click here for videoadjustable nitrogen and vortex mixingthe tribute™ features fully adjustable nitrogen and independently adjustable vortex mixing.  enjoy high coupling efficiencies with great mixing!barcode scanning of amino acid vialsloading amino acid vials is a snap with this feature!  just scan, load, and press the forward button!click here for videouser loggingthe tribute™ provides different levels of security for different users with its login screen.  ■ system access limited to authorized individuals■ user id and password provide an electronic signature for each user■ users may login as an administrator, designer or runnerpersonalized user databasesindividual users can cr-eate their own programs and peptide sequences that can only be accessed when they are logged in. files can be cr-eated on the tribute™ or on an external computer and transferred to the tribute™ via a portable usb drive:

e-mail notification featurehave the tribute™ send an email to your computer or cell phone at a specified program step, at the beginning of each cycle, or when an error occurs.safe response featurethe tribute™ can rinse and drain your reaction with a solvent of your choice if your synthesis is interrupted for any reason.automated cleavagethe tribute™ can deliver tfa to the reaction vessel from a solvent bottle or an amino acid vial.  afterwards, collect your cleaved peptide in a 50 ml centrifuge vial in the tribute™´s convenient collection stand.  just add ether directly to the collection vial and centrifuge to precipitate your peptide!automated cycle dependent volume incrementationthe tribute™ can automatically adjust delivery volumes to account for resin volume increases as your synthesis progresses.  delivery volumes will increase by an increment of your choice each cycle.
