          permitting an absorption measurement directly on the sample in

               The prior art references relied on by the examiner are:

                                                       (filed Apr. 4, 1989)           
               Claim 8 stands rejected under 35 U.S.C. § 102(b) as                    
          described by or, in the alternative, under 35 U.S.C. § 103 as               
          unpatentable over Lilja.  Claims 1, 3, 4, 7 and 12 stand rejected           
          under 35 U.S.C. § 103 as unpatentable over Pierre, Banauch,                 
          Draeger, or Tanaka, either of those references considered alone             
          or further considered in view of Lilja.  We shall reverse these             
          rejections.                                                                 
                                     DISCUSSION                                       
               The examiner's finding, that Lilja describes the disposable            
          cuvette of claim 8, is clearly erroneous.  We summarily reverse             
          the rejection of claim 8 under 35 U.S.C. § 102(b) as described by           
          Lilja.                                                                      
               With respect to the rejection of claim 8 under 35 U.S.C.               
          § 103 as unpatentable over Lilja, the examiner bears the initial            
          burden of presenting a prima facie case of unpatentability.  In
