Fermentations and cell cultures require tight control of system variables to achieve consistent, desirable results. Regulating variables such as oxygen, pH, and temperature has long been accepted as important for assuring viable processes. More recently, researchers have recognized the need to regulate nutrients and byproducts as well, and have determined that controlling them plays a vital role in the health and productivity of their processes.
The YSI 2700 SELECTTM Biochemistry Professional analyzer provides vital information about your processes. It provides rapid, accurate analysis of key nutrients and byproducts, including:
- Glucose
- L-Lactate
- L-Glutamine
- L-Glutamate
- Ethanol
- Lactose
- Sucrose
- Galactose

DEA 230 Epsilon
There are three different systems in the 230 Epsilon series of Dielectric Cure Professional monitors: the high-performance, 2-channel DEA 230/2 with the broadest measurement and frequency range, particularly for product development and process optimization, the single-channel DEA 230/1, and the 10-channel DEA 230/10, also suitable for applications in manufacturing.
For the investigation of the curing behavior of thermosetting resin systems, composite materials, industrial adhesives and professional paints, dielectric analysis (DEA) has stood the test of time because it can be employed not only on a laboratory scale, but also in process. Versatile sensors for almost every application are available for measurement of the ion viscosity.
The different models of the DEA 230 Epsilon can be connected to the dynamic mechanical professional analyzer DMA 242 C for simultaneous DMA-DEA analyses. The combination of these complimentary methods provides additional information for complete characterization of the crosslinking behavior of the reactive polymers. |

Many institutions are doing research and development on food. The aim is to improve the nutritional value of the food. The parameters may be to compare different foods or different manufactures or to generically improve the food. Other aspects may be to improve the digestion and energy absorption of animal feeds.
Part of the research involves determining the calorific value of the food. The calorific value of a particular food is the same as the energy content of that food.
The food can be for either human or animal consumption.
Institutions performing this type of research include:
Animal and Dairy research
Department of Agriculture
Universities
Technicons
Government or private food industries
A calorimeter is used to determine the calorific value. The sample to be measured is ground into a powder and then prepared into tablet form. The sample should be made into a tablet so as to prevent splattering when the sample burns. Splattering is when un-burnt sample is thrown out of the crucible during combustion, thus causing inaccurate results. In tablet form, feeds usually burn consistently and without splattering.

| VLM Sample Concentrators are an time saving alternative to rotary industrial evaporators, if there are many samples to be processed. For this purpose nitrogene is distributed by the gas supply unit and introduced into the test tubes, flasks, chrom. vials, microcentrifuge tubes, or wells of microtiterplates The flow of nitrogene can be individually adjusted. The evaporation cold is compensated by the metalblock thermostats manufacturers thus there is a constant temperature. Complete systems for 24,48, are available with a convenient lift or - for small budgets - with a stand. If samples have to be concentrated to a rest volume we recommend the EVA VIS model, which allows to watch the first row of samples placed into heating block with vertical slits. The evaporators shall be placed run in a hood but there is also a professional cabinet available you will find among accessories. For more information please visit our VLM Laborshop (www.vlm-laborshop.de) or give us a call 49 5202 919930. |

The WyattQELS (Quasi-Elastic-Light-Scattering) instrument contains a real time digital correlator. The correlator measures the autocorrelation function of the intensity signal from any one angle of the DAWN or from the 90 degree location of the miniDAWN. The correlator then calculates the hydrodynamic radius at each elution time in order to provide hydrodynamic radii over an entire chromatographic peak.
Unlike many other dynamic light scattering instruments, the WyattQELS detector, when interfaced to the DAWN, allows one to measure correlation as a function of angle. Particles larger than 150nm may scatter relatively little light at 90 degrees because of intra-particle interface or "Mie scattering".
Features
Multiple Tau correlation design with a fixed range of channel from 480 nsec to ~1 hour (real-time).
No sample time optimization required!
A total of 264 channels with input data format of 5 bit for the first 16 channels, the the sample time doubles every 8 channels and the data width is incremented 1 bit for every set of channels. No pre-scaling required.
