Pipette tips are used with pipettes and pipettors to speed processing and reduce cross-contamination. They are available in a variety of materials and styles. Popular pipette styles used are: Universal pipette tips, Filter pipette tips and Low retention pipette tips. Pipette.com offers a wide variety of first party and third party pipette tips
Filter capsules for rinsing tests. All filter capsules were of size 10" and were based on PES and PVDF membranes and are commercially available. They are used for sterilizing-grade filtration with a final membrane pore size of 0.2 or 0.22 µm. All filters were suitable for gamma irradiation.
Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either when fluids are initially drawn or delivered. Circular shaped in diameters that fit common syringe sizes, the cartridges remove fragments that would otherwise
Tygon ® Tubing. This broad range of flexible Tygon ® tubing products are engineered to meet many user specifications including chemical resistance, fluctuations in temperature, abrasion, high purity and long service life.
Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels.

Aijiren / VanKel / Varian Filters. Vankel dissolution baths can use different filters. The -01 filters fit on the 3.6mm (0.0142") cannulae and also on the 2.1mm (0.083") cannulae with flexible tygon tubing (tubing increases the diameter to 3.6mm). If the tygon tubing is removed from the 2.1mm cannulae then 'direct fit' filters should be used.
