I have a very viscous sample; will it go through the ProInsert?

It will go through but you can improve the outcome by treating your viscous sample with PureSperm Buffer before use. Dilute your sample with PureSperm Buffer 1+3 incubate in 37°C for 15-30 minutes, mix and it’s ready for the density gradient preparation. You can find more information on our website.
