The ConductScience Benchtop Turbidimeter provides precise turbidity measurements from 0 to 400 NTU with ±2% accuracy and repeatability. This compact analyzer employs standardized nephelometric detection to quantify suspended particle concentrations in aqueous samples across diverse research and analytical applications.
The instrument features 0.01 NTU resolution for high-precision measurements and includes dual cuvettes for efficient sample processing. With universal AC power supply compatibility (100-240V, 50/60Hz) and compact benchtop design, the turbidimeter integrates readily into existing laboratory workflows requiring reliable water quality assessment and particle suspension analysis.
How It Works
Turbidimetry measures the reduction in transmitted light intensity caused by suspended particles in a sample. The instrument directs a collimated light beam through the sample cuvette and detects the transmitted light intensity. Particles in suspension scatter incident light according to Rayleigh or Mie scattering principles, reducing the amount of light reaching the detector proportional to particle concentration and size distribution.
The nephelometric detection system correlates light attenuation with turbidity units (NTU), providing quantitative measurement of suspended particle density. The instrument's optical design minimizes stray light interference and maintains measurement stability across the 0-400 NTU range. Dual cuvette capability allows for reference blank correction and sequential sample analysis.

This turbidimeter combines research-grade precision (0.01 NTU resolution, ±2% accuracy) with practical laboratory features including dual cuvettes and universal power compatibility. The single 0-400 NTU range eliminates range switching while covering diverse analytical applications from environmental monitoring to pharmaceutical quality control.
Practical Tips
Use certified turbidity standards that bracket your expected sample range and verify calibration before each analytical session.
Why: Ensures measurement accuracy and traceability throughout the analytical sequence
Clean cuvettes with distilled water and lint-free tissue between samples to prevent cross-contamination.
Why: Residual particles from previous samples can bias turbidity measurements and reduce accuracy
Allow samples to reach room temperature and mix gently to achieve uniform particle distribution before measurement.
Why: Temperature differences and particle settling can cause measurement variability and non-representative readings
If readings appear unstable, check for air bubbles in the cuvette and verify the optical path is clean and unobstructed.
Why: Air bubbles and optical contamination scatter light and cause erratic turbidity measurements
Record replicate measurements and calculate standard deviation to assess measurement precision and identify outliers.
Why: Statistical analysis of replicates validates data quality and identifies potential sampling or measurement errors
Handle cuvettes carefully to avoid scratches on optical surfaces and wear appropriate PPE when measuring hazardous samples.
Why: Scratched cuvettes scatter light and compromise accuracy while hazardous samples require appropriate safety precautions
Position the instrument away from vibration sources and direct light to minimize measurement interference.
Why: Mechanical vibrations and stray light can affect optical stability and measurement reproducibility
Document sample preparation methods and measurement conditions to ensure reproducible results across analytical sessions.
Why: Consistent methodology is essential for valid data comparison and regulatory compliance in quality control applications

Compliance
What is the minimum detectable turbidity change this instrument can reliably measure?
The instrument provides 0.01 NTU resolution with ±2% repeatability, enabling detection of turbidity changes as small as 0.01 NTU under stable measurement conditions.
How frequently should the instrument be calibrated for quantitative research applications?
Calibrate with certified turbidity standards at the beginning of each analytical session and verify calibration periodically during extended measurement sequences to maintain ±2% accuracy.
What sample volume is required for accurate turbidity measurements?
Sample volume depends on cuvette specifications; consult product datasheet for exact volume requirements and minimum fill levels for accurate optical measurements.
Can this turbidimeter measure colored samples that may interfere with optical detection?
Colored samples may cause interference in turbidity measurements; use appropriate blank correction and consider color compensation methods or alternative analytical techniques for highly colored matrices.
What is the recommended warm-up time before taking measurements?
Allow the optical system to stabilize according to manufacturer specifications before beginning measurements; consult product datasheet for specific warm-up requirements.
How does this benchtop model compare to portable turbidimeters for field measurements?
This benchtop model provides higher precision (0.01 NTU resolution) and stability compared to portable units but requires AC power and laboratory conditions rather than battery operation for field use.
What data output formats are available for integration with laboratory information systems?
Consult product datasheet for specific data output capabilities, interface options, and compatibility with laboratory data management systems.
What maintenance procedures are required to maintain measurement accuracy?
Regular cuvette cleaning with distilled water, periodic calibration verification with standards, and optical component cleaning per manufacturer guidelines maintain measurement performance.
