The new gel-loading pipette tips are perfect for loading SDS or agarose gels. For SDS gels in particular, it is only possible to load the gel with great difficulty when using a normal pipette tip due to the relatively narrow sample well.
Agarose gels can be easily pierced when applying the sample, which can result in the sample being completely lost. Due to the high degree of flexibility of the elongated gel-loading tips, loading SDS gels is made considerably easier and it is also more difficult to damage agarose gels.
