Instituting economical ways to save electricity could save about three quarters of the electricity consumed in the U.S. at an average cost of about one cent per kilowatt-hour, according to Amory Lovins, chairman and chief scientist of Rocky Mountain Institute.

Laboratory Technology

Quality by Design (QbD) refers to the strategies developed and advanced by the US Food and Drug Administration, the International Conference on Harmonisation (ICH), and the United States Pharmacopeia (USP),1-5 based on scientific principles and risk assessment and focused on product and process understanding.

If your pipettes have not been calibrated recently, the quality of your results and the integrity of your data are questionable.
Ask the Expert

David Patterson, PhD, professor of computer science at the University of California at Berkeley, talks to contributing editor Tanuja Koppal, PhD, about big data—what it is, where it applies, and what lab managers can expect to gain by investing in it. He also provides guidance on where people can get more
information about (and help with) big data and the possible concerns they need to be aware of.
Lab Health and Safety
Lab Health and Safety Tips

The practice of forbidding smoking, eating, and drinking in laboratories is one of the basic good hygiene practices. Unfortunately, it is often one of the most frequently disregarded. Too many people seem to have a "good reason" for continuing these bad habits. None of these reasons are good enough.

Research-Specific Labs

A series of food safety crises, including melamine contamination in pet foods; E coli-tainted spinach, peppers and green onions; and a Salmonella typhimurium outbreak in peanut products have transformed food analysts from vigilant sentries into veritable centurions stridently safeguarding the quality, regulatory compliance and safety of our food.
INSIGHTS

Centrifuges work on the principle of sedimentation facilitated by an apparent angular force that draws components of a rotating sample away from the center of rotation. Although centrifugation theory is straightforward, its engineering literature is voluminous due to the number of industries and research operations that depend on the operation.
Surveys

Whether to employ central washing stations or point-of-use washers located under a lab bench or in a corner is also something that has to be addressed with regards to laboratory glassware washers. The former provide an economy of scale and are popular with lab workers who, almost universally, hate to “wash the dishes.” The downside for central washing stations is that glassware tends to disappear over time, due to breakage and operator error.

Gas chromatography (GC) is a common technique used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. GC is typically used for separating the different components of a mixture, improving the purity of a particular substance, or identifying a particular compound. GC is a ubiquitous technique, and the various GC instruments available are designed to achieve every requirement of the technique.

Common laboratory ovens maintain temperatures ranging from just above ambient to about 300°C and are ubiquitous in chemistry, biology, pharmaceutical, forensics, and environmental labs. Units operating at temperatures above 300°C are normally dedicated to specialized applications in physics, engineering, electronics, and materials processing. Typical lab ovens use four to six cubic feet of space and are located on benchtops or stacked atop another oven; other units may be much larger.
Maintenance Matters
How it Works

Problem: Vacuum pumps are laboratory workhorses, providing the conditions needed to run many lab applications. Unfortunately, pumps are also exposed to acid or organic chemical vapors that can cause some real maintenance issues. Particularly with oil-sealed, rotary vane pumps, the exposure of the oil to the chemical vapors can cause the oil to become corrosive, or to break down and no longer serve its vital lubricating function. Regular oil changes are needed to protect the pump.

Problem: In almost any laboratory or scientific research facility today, there are numerous devices, instruments or processes that require cryogenic fluids or gases supplied from cryogenic sources. The past quarter-century has seen cryogenic liquid cylinders expand from a rarity in laboratories with relatively few applications, to become the dominant mode of supplying high-purity gas and cryogenic fluids.

Problem: For a lab manager, these scenarios are all too familiar:
- A medical research lab has a -20°C freezer where the door is frequently left ajar and there is no door alarm.
- In an academic biology lab, a -20°C freezer is accessed on average 20 times an hour and also has a -80°C freezer that warms to -55°C routinely due to new lab students and sustained door openings, thinking “hmmm, what did I come here for again?”
- As a lab manager, you receive a phone call at 3 a.m. saying a freezer has alarmed which forces you to go into the lab in the middle of the night.

Design for atmospheric pressure ionization sources came of age in the late 1980s to provide a powerful analytical tool—the mass spectrometer —the ability to characterize analytes amenable to liquid chromatography as gas-phase ions removed from the liquid. The motivating force behind such invention has always been the need to answer questions better and faster with tools that provide greater utility.

Automation offers improved productivity, reduced manual input and the elimination of Safety Health and Environment (SHE) issues associated with solvent exposure.
Products in Action

When preparing biological samples, you need a lab assistant you can trust, one that is focused on consistency and reproducible results across 10’s and 100’s of samples. Advancing your science and increasing the pace of your experiments is your job! Being tied to the bench for routine pipetting tasks doesn’t have to be!
