25-mL Conical TubesEppendorf’s last tubes innovation—the conical tube format 25 mL—comes with new versions: Amber, Protein LoBind, and DNA LoBind. The innovative material of the amber-colored 25 mL conical tubes is highly transparent, while at the same time effectively protecting the sample from low-wavelength light. This way, the pipette tip immersion can be safely monitored during liquid transfer, which helps avoid cross-contamination.

An institution that has long influenced academia in the United States has lost credibility. The College Board—a nonprofit organization that oversees the development of Advanced Placement (AP) precollege courses and the administration of the SAT exam that is used in college admissions—has been caught in an outright lie about its practices, raising questions about its vulnerability to political pressures.
