Brookhaven Instruments products

Brookhaven Instruments’ scientists have extensive experience in the development of instruments and methods for light scattering. This experience has been incorporated into the BI-200SM Research Goniometer to make it the finest instrument available for research applications of light scattering.

The Brookhaven BI-DCP Particle Size Analyzer is a digitally controlled, high-resolution, particle size distribution analyzer. It yields high-resolution results in the size range from 0.01 to 30 microns with typical analysis times ranging from 5 to 30 minutes. The DCP software provides easy instrument control, data analysis, and database management. The software is menu-driven and permits a variety of report formats.

The BI-ZTU Autotitrator option for the NanoBrook zeta potential analyzers is ideal for automatic determination of the isoelectric point (IEP) of colloidal materials. Four pumps provide unparalleled flexibility for optimizing reagent use. The dramatic savings of reduced labor costs allow for larger scale studies that produce more valuable results.

The NanoBrook Series size and zeta potential analyzers incorporate all you need for fast, routine, sub-micron measurements of size and zeta potential. Based on the principles of Dynamic Light Scattering (DLS) for particle sizing and distribution, and based on Doppler velocimetry (electrophoretic light scattering or ELS) for zeta potential measurement, most measurements only take a minute or two. The instrument also includes Phase Analysis Light Scattering (PALS) measurements for samples with low mobilities.

The BI-DNDC is a deflection-type refractometer that may be purchased for use in either batch or GPC/SEC mode. In batch mode, the specific refractive index increment, dn/dc, is determined. This value is required as a parameter in molecular weight measurements using light scattering. In GPC/SEC mode, dn/dc is already known, and the instrument is used as a concentration detector for GPC/SEC applications.

The BI-MwA has the highest performance/price ratio of any light scattering detector used for molecular weight determination. Eliminate SEC/GPC column calibration and improve data quality. Rapidly reduce uncertainty with no assumptions required and true extrapolation to zero angle.

The BI-RIVS is a combination RI and Viscometry detector used in SEC/GPC determinations of the MWD using universal calibration.

The BI-RC27 is a 20mL scintillation vial made of borosilicate glass, with an outer diameter of 27mm. One box of BI-RC27s contains 100 scintillation vials with unfastened polyethylene caps included. BI-RC27 – Round glass sample cell, 27mm OD.

The BI-SCGO is a reusable glass square sample cuvette for use with organic solvents. These can be used for both DLS and zeta potential determination. Each box contains 10 cuvettes with caps, and each cuvette can hold approximately 4.5mL. The Bi-SCGO is compatible with the SREL solvent-resistant electrode. BI-SCGO – Square cuvette/cell, Glass, Open.

The BI-SREL is a solvent-resistant electrode used to determine zeta potential. This electrode can be used with most organic solvents and aqueous solutions. Check with Brookhaven Instruments for unusual solvents. The BI-SREL is compatible with both the BI-SCP and the BI-SCGO cuvettes.
