These pipette tips are manufactured to extremely high quality and purity standards and are designed to cover all of the specific needs of your samples. Offering reduced-force tip attachment and ejection with complete sealing, epT.I.P.S. work in perfect combination with your Eppendorf pipettes and form a fully integrated pipetting system that
Select a sample size to give 20 to 200 colony-forming units (CFU) per filter. The ideal sample volume for non-potable water or wastewater yields 20–80 coliform colonies per filter. For finished, potable water, the volume to be filtered will be 100 mL. When the sample volume is less than 20 mL (diluted or undiluted), add 10 mL of sterile dilution
The sample is then applied to the RNeasy MinElute spin column. RNA binds to the silica-membrane, contaminants are efficiently washed away, and high-quality RNA is eluted in water. Enzymatic reactions or crude RNA preps are simultaneously cleaned up and concentrated in less than 15 minutes.
