Though they say this winter on the east coast was NOT the longest or snowiest on record, I’m hard pressed to believe it. The stubborn patch of snow I’m looking at outside my office window indicates otherwise and shows absolutely no sign of melting...

A voluntary program to change lab practices saves money while promoting sustainability

How digital systems can save money, eliminate safety risks, and increase productivity

Negotiating skills can make the difference between disappointment and great joy in dealing with others to get what you need….and what you want.

Nongjian Tao, PhD, director of the Center for Bioelectronics and Biosensors at Arizona State University’s Biodesign Institute and professor in the School of Electrical, Computer, and Energy Engineering, talks to contributing editor Tanuja Koppal, PhD, about a new technique called plasmonic-based electrochemical microscopy (P-ECM) developed in his lab for imaging localized chemical reactions from single nanoparticles. He talks about the advantages of this technique when compared to conventional optical microscopy and scanning electrochemical microscopy (SECM) and its potential uses in diverse areas.

Analytical and QA/QC labs, under ever-increasing pressure to improve time to market, ensure compliance and realize cost savings, now have an all-inclusive informatics solution that gives them complete control over their methods and Standard Operating Procedures (SOPs) without having to purchase, integrate and validate software from multiple vendors.

Fluorescent western blotting is a powerful imaging technique which facilitates accurate protein quantification and multi-color analysis.  At Abcam, we listened to the demands of our customers, and generated high quality Alexa Fluor® 680/790 conjugated secondaries, to a large number of target species, for fluorescent western blotting.  As a result of this diversity and minimal spectral overlap of Alexa Fluor® 680 and 790, the reagents are ideal for multi-color analysis; furthermore customers can be reassured of the quality as Abcam publishes QC data for each individual product within the range.

When Wayne State University’s team began Phase II of its Chemistry building renovation, it was stumped by a seemingly simple question. Use a single blade damper terminal or a Venturi air valve technology to control its laboratory ventilation and exhaust system?

Recommended procedures for donning and doffing PPE for cleanrooms and containment labs

The use of warning signs to designate particular hazards is not just a good idea. It’s the law.

Learning to use evaporation starts very early in chemistry. For students, the process takes a very simple
 approach, maybe just putting a solution in a beaker over a flame and waiting. That technique, though,
 doesn’t provide the sophistication, control, or throughput that advanced techniques require. Consequently, scientists can use dedicated evaporators.

Microplate handlers are the robotic “glue” that unifies operations around a microplate workflow. The
 evolution of robotics and software has caused a “democratization” of lab automation in general, and microplate handlers in particular.

When preparing a sample for analysis that requires high temperature and pressure in an acidic environment, a scientist selects microwave digestion for the process. This attracts scientists from an extraordinarily large range.

Total organic carbon (TOC) analyzers present a rapid, efficient measure of the carbon contamination content of public drinking water and ultrapure water for lab operations.

Most HPLC analyses employ some form of sample preparation, especially with low-concentration analytes in complex mixtures.

“Is my water safe to drink?” Getting the answer to that question is Russell Leu’s main goal as section supervisor of the environmental laboratory in the Montana State Department of Public Health & Human Services (DPHHS).

The pros and cons of high-performance liquid chromatography (HPLC) compared with ultra-high performance LC (UHPLC) are by now the stuff of legend.

Because baths and chillers are such a basic piece of laboratory equipment, it’s easy to put them in a corner and forget about them. But, as with other instruments, maintaining your bath or chiller is extremely important.

Problem: Rotary vane, or oil-based, vacuum pumps, are a common piece of equipment found in most
labs. A vacuum pump is an accessory used with equipment such as freeze dryers, vacuum concentrators, glove boxes, and vacuum ovens. Just as in your car, the oil in a rotary vane pump needs to be changed periodically in order to run at its optimum. The ramifications of not doing regular oil changes is poor vacuum and seizing up the pump’s internal components, which can destroy an expensive pump.
