Abstract

A container (1) for storing a bodily fluid, for example a blood collection tube (2), comprising: an interior space (4) configured to store the bodily fluid; and a wall (5) enveloping the interior space, wherein a surface of the wall (5) facing the interior space (4) of the container (1) forms a contact surface (6), wherein at least a portion of the contact surface (6) is provided with a primer coating (7), wherein the primer coating (7) is formed from a perfluorophenyl azide (PFPA) including an azide group (9) and a functional group (10), and wherein a co polymer made from poly (N-vinylamine-co-N-vinyl acetamide) is bonded to the functional group (10) of the primer coating (7). The invention also relates to a method for coating a contact surface (6) of a container (1) for storing a bodily fluid.

PEG/PEO-PPO-copolymers,   b. poly-(3-methacryloylaminopropyl)-(2-carboxyethyl)-dimethylammonium-carboxybetain-methylacrylamid (pCBMAA-1), or   
       c. polypeptide-based block copolypeptides. 
     
     
         2 . A container ( 1 ) for storing a bodily fluid comprising:
 an interior space ( 4 ) configured to store the bodily fluid; and   a wall ( 5 ) enveloping the interior space,   wherein a surface of the wall ( 5 ) facing the interior space ( 4 ) of the container ( 1 ) forms a contact surface ( 6 ),   wherein at least a portion of the contact surface ( 6 ) is provided with a primer coating ( 7 ),   wherein the primer coating ( 7 ) is formed from a perfluorophenyl azide (PFPA) including an azide group ( 9 ) and a functional group ( 10 ),   wherein a copolymer made from poly(N-vinylamine-co-N-vinyl acetamide) is bonded to the functional group ( 10 ) of the primer coating ( 7 ), and   wherein the container is a blood collection tube ( 2 ).   
     
     
         3 . The container of  claim 1 , wherein the container is a blood collection tube ( 2 ).
