The Drummond EZ Grip Tissue Culture Nosepiece eliminates the possibility of cross-contamination due to over-pipetting. It incorporates a dual hydrophilic 0.8 Μm, hydrophobic 0.8 Μm filter which prevents further use once contaminated by fluid. 
 
This double membrane filter provides a barrier to particles as small as 0.1 Μm. Each kit contains all necessary parts including four filters. Extra filters may be ordered separately.
