Laboratory Service

Welcome to BSI Advance Laboratory

Our advance laboratory is equipped with a test apparatus which complies with internationally recognized test standards (ASTM & ISO Standard), and allows the user to measure filter media performance under defined conditions with regard to the  filtration velocity, particle size distribution, and cleaning requirements.

The advanced lab is also equipped to measure tensile strength and flex strength, and can conduct particle size analysis, microscopic analysis, fabric permeability analysis, and chemical analysis.

Instrumental Analysis Laboratory

Scanning Electron Microscope (SEM)

Membrane structure or pore morphology was investigated by using scanning electron microscopy (JSM-IT100).

► Pore and/or particle size ► Membrane morphology ► Membrane structure

Capillary Flow Porometer (PMI)

Trans-membrane pore size distribution was measured by the combined gas flow/pore dewetting method.

Laser Particle Size Analyzer

► Measurement: Particle Size

► Particle size range: 0.01 um to 3500 um

► Dispersion type: Wet, Dry   

► Technology: Laser Diffraction 

Spectrophotometric Analysis For Water Quality

UV/VIS Spectrometer Analysis:

► Free Chlorine and Total Chlorine ► COD (Chemical Oxygen Demand) ► TOC (Total Organic Carbon )   ► Ionic Content Test 


Wide measuring range using three selectable readout modes—0 to 4000 nephelometric turbidity units,

0 to 26,800 NEPH (Nephelos), and 0 to 980 EBC (European Brewing Convention)


Fourier Transform Infrared Spectroscopy (FTIR) Analysis:

► Chemical structure ► Unknowns Identification (Solids and Liquids) ► Impurities or Toxicity Screening


Rotational viscometers use the idea that the torque required to turn an object in a fluid is a function of the viscosity of that fluid.

They measure the torque required to rotate a disk or bob in a fluid at a known speed.

Separation Technology Laboratory

Filter Efficiency Testing Equipment

► Standard Practice for Determining the Performance of a Filter Medium Employing a Single-Pass, Constant-Rate, Liquid Test.

► Test Procedure: ASTM F795-88

Liquid Particle Counter

► The optical particle counters are volumetric particle counters with a variety of sizing sensitivities as low as 0.5 microns.

► They provide high precision analysis for most process chemicals including hydrofluoric acid and hot corrosive chemicals up to 120°C.

Silt Density Index Test Meter

► It is generally used to measure the SDI value before RO inflow, preferably below a certain value to increase the life of the RO membrane or the rear filter.

► Based on ASTM Method 4189-95.
► Minimum water sample requirement: 20 L
