These pipette tips are great. we used the tips with our gilson pipettes and they fit very well. so I consider them universal fit.

The pipette tips do not fit the box and are unusable since they slip in the hole when you press the pipette down. Not functional and now need to order from a different company. They fit the pipette, but after autoclaving in a box, they are worthless.

The tips from this large bag from Kashi Scientific fit onto a Cekegon 100-1000 μL micropipette that I ordered for a project. The two made a budget-friendly combination.The Cekegon adjustable micropipette can go to 1000 μL max, so that’s the size of tips I ordered. I chose that size to avoid disaster if I accidentally set the pipette too high for the tip– for example, setting it at 1000 μL when it has a 200 μL tip on it could cause fluid to be drawn up into the pipette, which would ruin it. So I ordered tips that matched the max volume of the pipette. I don’t know if this is standard practice, but it worked for me.The tips were labeled “sterile”, and came in a heat-sealed bag with tear-off notches at the top. There’s a ziplock closure below the notches; I only tore off a few inches on one side, and kept the rest sealed, to lessen the risk of contamination.Not sure what else to say. They’re tips! They worked!Remember to wear gloves and reseal the bag quickly to lessen the risk of contamination.

First off, let me just say that I'm not using these in a biological lab, so I can not attest the sterility and lack of human genetic material.I use a cheap 1mL micropipette for general chemistry because it is easier to use over any available pump for glass pipettes. I don't usually do anything super exotic, so polypropylene is acceptable to me. My cheap micropipette is fairly precise and dispenses volumes that I work with, so this bag of tips is a win for me.
