The first cup having a chamber containing a first absorbent material, a first disinfectant or an antimicrobial agent in the first cup, and a first peelable seal. The second cup having a chamber containing a second absorbent material, a second disinfectant or an antimicrobial agent in the second cup, and a second peelable seal. A threaded connection is disposed on the bottom exterior surface of the first cup having threads that are sized and pitched to engage threads of a luer lock collar on the distal end of the syringe barrel to allow the first cup to be connected to the syringe assembly. The second cup and the syringe assembly are interlocked through interference fit or snap fit of the thumb press of the syringe and ledge of the second cup.
