Instrumental Analysis Laboratory

Welcome to BSI Adv. Lab. Center 

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.


Automatic Digital Refractometer

Measures Refractive Index over a wide range, from 1.3250 to 1.7000, with a measuring temperature range up to 70°C.

This is ideal for samples with a high Refractive Index, oils and fats with a high melting point, and other similar samples.


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)


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.

Contact Angle Goniometer

If the water contact angle is smaller than 90°, the solid surface is considered hydrophilic, ex: PES、PVA、Glass

And if the water contact angle is larger than 90°, the solid surface is considered hydrophobic, ex: PP、PVDF、PTFE

Particle Sizing Instrument

► Measurement: Particle Size

► Particle size range: 0.01 um to 3500 um

► Dispersion type: Wet, Dry

► Technology: Laser Diffraction

Tensile Tester

Tensile testing is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure.

Infrared Spectrometer (FTIR)

Fourier Transform Infrared Spectroscopy (FTIR) Analysis:

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

Capillary Flow Porometer (PMI)

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

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
