DNA and PCR studies involve molecules like DNA/RNA and proteins that have a tendency to bind to plastic pipette tips.
Molecules like DNA/RNA and proteins have a tendency to bind to plastic pipette tips, leading to errors, transfer losses and cross contamination.
So-called "low retention" tips merely prevent liquid adhering to the pipette tip, so that even if all the liquid has been expelled valuable molecules can still be retained, bound to the tip surface.
Available in the UK exclusively from Camlab, AvantGuard barrier pipette tips are low retention tips, but also feature a unique surface treatment that significantly reduces binding.
In an independent evaluation, AvantGuard tips showed four times less DNA retention than the best conventional low retention tips.
They also incorporate a high quality polyethylene barrier that prevents contamination of the pipettor shaft to minimise the risk of carry-over.
AvantGuard tips are certified free of RNase/DNase, human DNA/PCR inhibitors and trace metals and are non-pyrogenic.
They are suitable for all the most popular pipettors - Socorex, Ranin, Gilson, Eppendorf, Labsystems and Biohit - and delivery volumes from 10 microlitres to 200 microlitres.
Labs particularly recommend AvantGuard tips for PCR and other applications where aerosol contamination is a concern, for less carry-over and less DNA and Taq bound to the walls of the tip.
