AAPPTec - Complete Peptide Product Source

The amino acid and reagent solutions are stable without degradation or racemization during the length of most synthesis proceedures on the Apex 396.  We recommend that amino acid solutions and coupling reagent solutions should be freshly prepared at the start of each library synthesis. 

You can use as many or as few reactor wells in Apex 396 as you need.  You do not have to utilize all 96 reactor wells.  The Apex 396 reactor assembly is divided into 4 zones.  We recommend that nitrogen pressure should be switched off in unused zones to improve performance.

You can use one of the optional reactor assemblies that have larger reactor wells.  Reactor assemblies with 40 five mL wells, 16 ten mL wells, or 8 twenty mL wells are available for preparing peptides on larger scale.  Alternatively, you can synthesize the same peptide in more than one reactor well.  The Apex 396 produces highly uniform peptides across many wells.

You only need to change the filters if you are having trouble emptying the reactor wells.  Using high quality resins without "fines" will increase the usable lifespan of the filters.

You may have to replace the isolation isolation block on the affected arm.

No, the Apex 396 does not have heating or cooling capabilities.
