An arrangement of serum separation tube 10 or other evacuated tube or container is provided which type of tube requires the addition of a variety of different additives, depending upon the use which is to be made of the tube and/or the test to be carried out once a sample of blood has been introduced. The invention contemplates a simplified form for adding reagents to different tubes by introducing by mass production techniques reagents as required simultaneously to separate pieces of paper and/or polyester. The separate pieces 18 with reagent thereon are subsequently introduced into individual separation containers or tubes as required. The introduced pieces will have the required quantity of reagent thereon for the particular test involved. |
