Equipment

1. 10 ml disposable plastic syringe fitted (heat sealed) with a 200 μl pipette tip
   Using a Bunsen burner, heat and partially melt the wide end of a 200 μl pipette tip. Before the plastic has time to harden quickly insert the melted end of the 200 μl pipette tip into the luer-lok of a disposable plastic 10 ml syringe. Let the assembly cool and check the tightness of the seal by running 10 ml of water at high pressure through the syringe/tip assembly.
