Selecting the Right Cell Culture Media

Whether the objective is cell-based assays, antibody production, or virus replication, your cell culture medium is a make-or-break component

The vast majority of laboratory-scale cell cultures are initiated for pure research. Labs that use one cell line throughout a project acquire the cells, authenticate them, and expand them sufficiently for the lab’s purposes.

New Applications for Molecular Spectroscopy

Some of the challenges associated with fast, real-time testing, comprehensive analysis of samples do exist but continue to be addressed with improvements in the technology

"In my opinion, the possibility of using FTIR in a high-throughput manner is very attractive, especially for toxicity screening tests," says Vinka Oyanedel-Craver, PhD, associate professor at the Department of Civil and Environmental Engineering at the University of Rhode Island.

Managing Laboratory Noise

Many areas within laboratories are inherently noisy. Exposure to loud noise for long periods can result in hearing loss

Noise is measured as sound-pressure levels in units known as decibels (dB). In standard workplaces, OSHA limits employee noise exposure to 90dB averaged over an eight-hour work shift (measured on the A-scale with slow response using a standard sound-level meter/ SLM). This is referred to as the permissible exposure limit (PEL).

Titration Automation Guide

Automating titration solutions means more than simply the titration results and calculations performed by automatic titrators. Sample preparation steps and operator independent sample series analysis must also be included. The main focus is on the repeated analysis of routine tasks.

Why Automate?

  • Improve results quality
  • Increase efficiency
  • Provide result security and compliance

Maintaining Your Lab's Cold Chain

Refrigerators and freezers are integral pieces of equipment in many research and clinical labs

Low temperatures are required to preserve samples and specimens, ensure vaccines and drugs do not degrade, and keep certain reagents from spoiling. Often, though, temperature-sensitive materials must be collected or transported beyond the confines of the lab.

Flipping the Switch on Ammonia Production

Process generates electricity instead of consuming energy

Nearly a century ago, German chemist Fritz Haber won the Nobel Prize in Chemistry for a process to generate ammonia from hydrogen and nitrogen gases. The process, still in use today, ushered in a revolution in agriculture, but now consumes around one percent of the world’s energy.

Refractometers: Secrets of Accurate Measurement

Many factors can negatively affect accuracy in refractometry. The secret is to eliminate them

A $100 handheld refractometer should not be used for pharmaceutical QC, but such an instrument might work for educational settings or rapid raw materials testing. Field measurements, including determination of fruit ripeness, represent another “quick and dirty” application for inexpensive refractometers.
