The Eppendorf Combitips prevent aerosol contamination even when working with aggressive, radioactive, or toxic material due to the hermetically sealed piston.

While bulk tips might be the best option out there for labs where the budget is tight, Racked Sterile Tips are a much better option for labs where sterility is paramount and the time of scientists and lab technicians is valuable and there is no extra time available to be constantly refilling and reracking tip boxes every time one is emptied. This is especially true in labs where a lot of multi-channel pipettes and multi-well plates are used, as these labs will often go through an enormous amount of tips per day and would simply not have the time to be refilling tip boxes every time they need to plate up a new plate. Using a multi-channel pipette, you could empty a tip box in minutes. In these situations, it is best and makes the most sense to be able to just open another fresh box of Racked Sterile Tips.
