Chemical, water or other analysis requiring exact measurement and dispensing of liquid reagents relies on the use of pipettes. Some pipettes are disposable, however, reusable glass pipettes are preferred because they are typically of higher quality and are calibrated more exactly.

The oxygen radical absorbance capacity (ORAC) assay is an analytical method to determine the antioxidant potential of nutraceutical, pharmaceutical and food ingredients.

The answer is simple: if you use your balance at all, regular calibration is critical. The question frequently comes up when a balance is initially purchased. A new balance operator’s manual almost always recommends calibration before use

Troubleshooting, scheduling, communicating, and consulting are just part of lab manager Lisa Wright's many responsibilities

Although gold nanoparticle production can be controlled to yield specific size ranges, both the concentration and size of nanoparticles must be checked following production. UV-Vis spectrophotometry is an established QC method for this; however cuvette spectrophotometers often require dilution of the nanoparticle solution before measuring, and volumes up to 3 mL.

While searching for that extra degree of safety in your laboratory or trying to remove fumes/gases from the laboratory environment NuAire has the proper canopy connections to exhaust your Class II, Type A2 Biological Safety Cabinet.

With the expansion of the global nutraceutical market, the spotlight on the analysis of its raw materials is ever increasing. Testing of nutraceutical products for heavy metals like lead, arsenic, cadmium and mercury has gained utmost importance. Extremely low levels of these heavy metals like mercury, in nutraceuticals make its analysis challenging.

Solvent removal from solutions is commonly performed in laboratory and production processes. There are a number of different methods that can be used for solvent removal, including evaporation, vacuum concentration, lyophilization, reverse extraction, solute precipitation, and dialysis (solvent exchange).

This Application Note will demonstrate the extraction of 1,4-Dioxane from an aqueous matrix using Option 1 of EPA Method 522 for 500 mL initial volume sample. It will make use of the SmartPrep Cartridge Extraction System to produce a valid Initial Demonstration of Precision (IDP) and Initial Demonstration of Accuracy (IDA).

Rotational viscometers are the most widely used tool in today's QC labs for making viscosity measurements.  Many small changes, like reduction in sample size and shortening the viscosity test time, can lead to significant increase in QC lab productivity.

The Cleveland Fire Department's mobile lab begins and ends with equipment.
