Frequently Asked Questions
Q: If there are no additives in the plastic used to make your tips, how are you able to achieve low liquid retention?
A: Some manufacturers use additives that alter the hydrophobicity of their plastic so that their tips provide low retention capability. NanoScreen does not believe that this is the best solution or that it is even necessary. By employing a high polish technique during the manufacturing of our molds, we are able to achieve an ultra-smooth finish on the surface of both the core pin and the cavity. This translates directly into an ultra-smooth finish on the interior and exterior surfaces of our pipette tips. Thus providing low retention capability.
Q: What is the difference between the P30 and the P10 384 tips?
A: The internal diameter of the P30 pipette tip is larger than that of the P10 - offering a 30uL capacity versus a 10uL capacity. The external dimensions of the two tip types are identical. Both are designed to work with the CCS style or Type-A 384 channel head. These heads are found on NanoScreen's Factory Certified Multimeks, PerkinElmer's PlateTrak, MiniTrak, EP3, LumiLux, and Janus systems. They can also be found on earlier versions of Molecular Devices' FLIPR systems.
Q: Is there a performance difference between the P10 and P30 pipette tips?
A: At volumes of 1uL and above, both tips will provide equivalent performance in terms of precision and accuracy. Below 1uL, the P10 will provide progressively better performance as the volume goes down. Though the P30 performs very well at the 500 nL level and has even been used successfully at the 250 nL level, the P10 will provide consistently better results in this volume range .
Q: What is the volume capacity of your aerosol barrier tips?
A: On the P30 Aerosol Barrier tip, the maximum usable capacity is 30 uL. On the P10, it is 10 uL.
