Description of Event or Problem

IN JUNE 2006, ROCHE MOLECULAR SYSTEMS, INC. PROVIDED A PRODUCT BULLETIN CLARIFYING THE USE OF THE GOLD PLATED HEAT BLOCK AND THE ALUMINUM HEAT BLOCK ON THE APPLIED BIOSYSTEMS GENEAMP PCR SYSTEM 9700 THERMAL CYCLER. IN RESPONSE TO THE THE BULLETIN, THE CUSTOMER REPORTED THEY HAD BEEN USING THE ALUMINUM HEAT BLOCK WHEN PERFORMING THE AMPLICOR CT/NG TEST. THE ALUMINUM HEAT BLOCK WILL NOT ACCEPT A MAXIMUM RAMP SPEED WHICH IS REQUIRED TO PERFORM THE AMPLICOR CT/NG TEST. THE CURRENT AMPLICOR CT/NG TEST PACKAGE INSERT DESCRIBES THE SETTING OF THE TEMPERATURE RAMP SPEED TO MAXIMUM BUT DOES NOT IDENTIFY THE HEAT BLOCK TO BE USED.
