+ infoDynamic viscosity measurement for laboratory and industrial applications
Dynamic viscosity measurement is essential for evaluating how liquids and semi-solid materials resist flow under applied force. Accurate viscosity data supports product development, quality control and process optimisation across a wide range of industries.
Fungilab provides complete dynamic viscosity measurement solutions based on precision rotational viscometers, temperature control systems and specialized accessories designed to deliver reliable, repeatable and traceable laboratory results.
Whether measuring low-viscosity liquids or highly viscous materials, Fungilab offers instruments adapted to routine laboratory testing as well as demanding research applications.

Dynamic viscosity
Viscosity is part of the science of Rheology which quantifies the resistance materials give to changing shape.
Proper interpretation of viscosity data can reduce the rate of rejects while keeping production and formulation development costs to a minimum. Consistent product quality is ensured through proper viscosity measurements, either alone or in conjunction with compatible tests.
Dynamic viscosity testing can help with:
- Material characterization or “finger-printing”
- Standard testing methods to check for differences between batches
- Indirect way of measuring quality
- Product formulation
- Quality control
- Process control
- Design, optimization and operation of process equipment

Newton’s Law
According to Newton’s law, the viscosity of a fluid is constant. As shear rate changes, shear stress changes in proportion such that viscosity is constant. Common fluids that exhibit such behavior are:
Unfortunately for us, not all fluids follow Newton’s law. In fact, most fluids do not. For this reason, fluids are classified into two categories:
Rotational Viscometer
The viscosity is calculated from the measured torque and rotational speed, as well as the dimensions of the measuring geometry.
A fluid’s resistance to flow is measured by the torque it exerts on the rotating shaft of the viscometer.
Absolute viscosity: the measuring geometry fulfills certain requirements (which is the case of coaxial spindles).
Relative viscosity: the dimensions of the measuring geometry are not well defined.
Advantage
Flexibility in:
- Viscosity Range
- Temperature range
- Shear rate range
Application
For Newtonian and non-Newtonian substances and temperatures different from room temperature.
Professional TLC chambers for chromatography laboratories
TLC chambers, also known as developing chambers or separation chambers, are used during thin-layer chromatography to create a saturated solvent atmosphere that promotes uniform mobile phase migration across the TLC plate. Proper chamber design is essential for obtaining reproducible Rf values and consistent analytical performance.
Types of TLC chambers
Fungilab offers several chamber configurations to suit different laboratory requirements:
- Normaplak chambers for standard 200 × 200 mm TLC plates.
- Multiplak chambers capable of accommodating multiple plates simultaneously for higher laboratory throughput.
- Miniplak chambers designed for compact 100 × 100 mm TLC plates.
Each chamber is manufactured from tempered glass with precision-ground surfaces to provide an excellent seal and stable chromatographic conditions. :contentReference[oaicite:1]{index=1}
Applications of TLC chambers
- Pharmaceutical quality control.
- Chemical laboratories.
- Food analysis.
- Cosmetic product development.
- Academic and research laboratories.
- Method development and validation.
Why chamber quality matters
A properly sealed TLC chamber minimises solvent evaporation and allows the atmosphere inside the chamber to become saturated before plate development. This improves separation reproducibility, reduces experimental variability and produces more reliable chromatographic results.
Benefits of Fungilab TLC chambers
- High-quality tempered glass construction.
- Excellent chemical resistance.
- Reliable solvent saturation.
- Precision-ground lids for improved sealing.
- Available for different TLC plate formats.
- Suitable for routine laboratory and research applications.
Fungilab manufactures a broad range of laboratory equipment in addition to viscosity measurement instruments, including TLC chambers developed for professional chromatography laboratories. :contentReference[oaicite:2]{index=2}
