General description :
For very special applications, BMG LABTECH offers dedicated plate readers, such as the NEPHELOstar, RUBYstar and LUMIstar OPTIMA. The NEPHELOstar, a laser-based microplate nephelometer, is used for solubility testing of compounds as well as for detection of bacterial growth.
The NEPHELOstar microplate nephelometer detects particles in liquid samples by measuring forward scattered light when a laser beam is directed through the solution. This scattered light is detected at angles of up to 80 degrees, making it approximately thirty times more sensitive than tradional transmission readers that measure the reduction in direct light passing through a sample well.
Flexibily and performance of the NEPHELOstar allow more applications to be adaped to microplate-based laser nephelometry than ever before:
- Automated drug solubility screening
- Microbial growth kinetics monitoring
- Precipitation and polymerization monitoring

The Aurora Nephelometer delivers increased accuracy in studying particulates and their source of origin.
The effects of air pollution on human health and lifestyle are of a major concern today. There are many parameters contributing to air pollution, of which airborne particulates are a major contributor.
Nephelometers give indications of air quality by measuring the light scattering of particles in the air. This translates to visibility measurements and information for global warming studies.
The “new generation” of Aurora nephelometer is available in four models:
Aurora 1000 Nephelometer (single wavelength)
Aurora 2000 Nephelometer (PM2.5 correlation)
Aurora 3000 Nephelometer (3 wavelengths with backscatter)
Aurora 4000 Nephelometer (polar nephelometer)
The wavelengths are characterized as follows:
Blue : 450nm Fine & ultra fine particulates (wood fires, automobiles)
Green : 525nm Visibility (smog, fog and haze)
Red : 635nm Large particulates (pollen, sea salt etc)
Applications
- Visibility Measurements (Airports, City pollution, AAQMS)
- Dust/Sand storm monitoring and early detection networks
- Global warming studies (light scattering/radiation balance)
- Bushfire/pollution monitoring and early detection networks
- PM2.5 mass measurement correlation studies
Features
- Low power instrument (ideal for remote applications)
- Low maintenance
- Low cost of ownership
- Advanced LED light source
- Compact and portable

The most important parameters needed for water analysis, especially in drinking water are now available in a portable meter.
You can obtain lab performance in the field by using the HI 93102.
It not only measures turbidity, but also pH, total and free chlorine, bromine, iodine, iron and cyanuric acid (CYS).
All this in the palm of your hand and in seconds!
Measurements are made quickly and repeatedly through a sophisticated, yet easy-to-use microprocessor.
In colorimetric mode, users can select between factory preprogrammed calibration or calibrating the meter on their own, and measure either concentration or relative absorbance of the sample.
Up to 25 measured samples can be stored in memory together with time and date.

The HD25.2 is a digital turbidity meter for laboratory and mobile use, suitable for measurements in drinking water, beverages, waste water and process liquids. The working principle is based on the nephelometric (90° scattered light sensor) and ratiometric method. It is equipped with three light detectors and two LED light sources (white and infrared) which are permanently kept under control in order to guarantee long-term stability. The instrument performs measurements according to the standards EPA 180.1, ISO-NEPH (ISO 7027), EBC and ASBC. It is also able to carry out measures of transmission factor percentage of white and infrared light. Stabilized power supply and advanced electronics garantee optimal performances over time. The HD25.2 is a datalogger that stores up to 999 samples. The data can be transferred from the instrument connected to a PC via the multi-standard RS232C serial port and USB 2.0. The RS232C serial port can be used to transfer the acquired measurements to a 24 col-
umn printer. The dedicated software DeltaLog11 allows instrument management and data processing on PC.
