Homogenizers: Multitude of Methods for Extraction From Non-Liquid Samples
Homogenization seeks to create samples in which analytes of interest are dispersed uniformly throughout. Numerous technologies can achieve this, including pressure, mechanical (rotorstator or blade-type), and bead-beating. “Depending on the application, one approach may be more appropriate than others,” notes Holly Yacko Archibald, sales director at PRO Scientific (Oxford, CT).

HPLC Systems: Employment Trends, Modularity, UHPLC, and New Life for Liquid CO2
Many labs today face downsizing, a trend that began before the economic downturn of 2008. “Employers are more likely to retain analytical scientists who can not only press buttons and achieve the appropriate results, but who can also quickly perform unaided troubleshooting, develop methods, and generate consistently reliable data,” says Ade Kujore, marketing specialist at Cecil Instruments (Cambridge, UK).

It’s Not Only About Throughput
Automated liquid handling (ALH) grew from the highthroughput needs of medical diagnostic labs in the late 1980s through the 1990s and then received an additional boost from genomic sequencing. As it evolved from a specialized, expert-driven instrument system to a generalized laboratory workstation, ALH has become more accessible to more workers in more labs. Learn more

HP 5890 column head pressure issues
I am having issues with my HP 5890. When the unit is powered up, it sucessfully goes through the self check. The issue is that the column head pressure is measuring zero. I have adequate pressure feeding into the unit. Can anyone offer suggestions on what the issue is? Read this discussion

Eppendorf microfuge fan always on
Standard bench 5415C microfuge. Has a fan in the bottom face. This fan normally only blows when the fuge is active (rotating). In one of ours, the fan is now blowing all the time. Some sort of a short, presumably? Unplugging the unit in search of a "reset" does nothing to help - the fan comes back on immediately when re-plugged to socket. Same for activating/ending a centrifuge run.The speed and time controls for the centrifuge work fine. Anyone know how to fix this fan activation/inactivation sequence? (not "buy a new one") Provide an answer
