U9-E08. Portable Tándem NanoScan SMPS Nanoparticle Sizer 3910 and Optical Particle Sizer (OPS) 3330

Equipment funded by European Union (NextGeneratioEU) -Plan de Transfomación y Resilencia

Portable Particle sizers acquired for Unit 9 in NANBIOSIS through Next Generation Funding.

Description: NanoScan SMPS™ Nanoparticle Sizer delivers a TSI Scanning Mobility Particle Sizer (SMPS™) spectrometer in a portable package that is about the size of a basketball. Easy to use, lightweight and battery-powered, the NanoScan SMPS™ spectrometer enables investigators to collect valuable nanoparticle size data. The NanoScan SMPS™ Nanoparticle Sizer spectrometer is suitable for a variety of applications, such as a multitude of mobile studies, workplace exposure monitoring, point source identification, and student lab education. Derived from TSI core technologies, the NanoScan SMPS spectrometer is an innovative, cost effective solution for real-time nanoparticle size measurements.

Technical Specifications: Weighing less than 20 pounds (including two hot-swappable batteries), the NanoScan SMPS™ Nanoparticle Sizer 3910 measures nanoparticle size distributions from 10 to 420 nm in one minute. Its internal Condensation Particle Counter (CPC) uses isopropyl alcohol as a working fluid, so the NanoScan is suitable for use in a variety of sensitive environments. Single particle mode allows the user to monitor particle concentrations of a single, user-set particle size. Data logging is built in to the instrument, so measurements may be made without the use of a laptop.

As a package, i.e. the model 3910 combined with the Optical Particle Sizer (OPS) 3330 enables users to measure three orders of size magnitude from 10 nm to 10 µm. These instruments are affordable, portable, and provide real-time data that can be merged with the multi-instrument manager (MIM) software. Used already for cabin measurements in cars and airplanes, the sky is literally the limit when it comes to new applications. Quantification thresholds reach to maximum concentrations of up to 150.000 particles per cm3.

Applications: General applied research; Indoor/outdoor air quality investigations; Nanotechnology/nanoparticle applications; Combustion/emission research; Mobile studies; Health effects/inhalation toxicology; Occupational hygiene/workplace exposure monitoring; Point source identification.

U6-E16. Freeze Dryer

Freeze drying (also known as lyophilization) is a water (or other solvents) removal process typically used to preserve materials, to extend their shelf life or reduce its weight. Freeze drying works by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change directly to a vapor (sublimation).

Freeze drying occurs in three phases:


Freezing can be done in a freezer, a chilled bath (shell freezer) or on a shelf in the freeze dryer. Cooling the material below its triple point ensures that sublimation, rather than melting, will occur. This preserves its physical form.

              2-Primary Drying

Freeze drying’s second phase is primary drying (sublimation), in which the pressure is lowered and heat is added to the material in order for the water to sublimate. About 95% of the water in the material is removed in this phase. Primary drying can be a slow process.

             3-Secondary Drying

Freeze drying’s final phase is secondary drying (adsorption), during which the ionically-bound water molecules are removed. Most materials can be dried to 1-5% residual moisture.

Technical Specifications:

  • Vacuum pump: 7 m3/h
  • Condenser min. Temperature: – 80º C


Solvent removal is typically used to preserve materials, to extend their shelf life or reduce its weight.

U6-E05. Tangential flow filtration system

Tangential flow filtration (TFF)  is a process of separation widely used in bio-pharmaceutical and food industries. It is different from other filtration systems in that the fluid is passed parallel to the filter, rather than being pushed through a membrane perpendicularly which can clog the filter media. This method is preferred for its continuous filtration and reproducible performance. The particles that pass through the membrane, the permeate, are put off to the side, while the rest, the retentate, is recycled back to the feed.

 Technical Specifications:

  • Volume: 10 ml
  • Filtration volume rate: 0.01 to 2300 ml/min

Aplications: Tangential flow filtration is used in the following processes:

Concentration: Increases the concentration of a solution by removing fluids while keeping the solute molecules. This process is done by selecting a filter significantly smaller than the solute molecules to allow for a higher retention of solute molecules.

 Diafiltration:  The separation of small and large particles, leaving the smaller particles behind without altering the overall concentration.

U6-E08. Mastersizer 2000

Mastersizer 2000 – Malvern


The Mastersizer 2000 uses the laser diffraction technique to measure the size and particle size distribution of materials. This is carried out by measuring the intensity of light scattered when a laser beam passes through a sample of dispersed particles. The detectors measure light intensity for red and blue light. The data is analyzed to calculate the size of the particles that created the scattering pattern.

The equipment contains two sample dispersion units:
– Wet: for samples in solution, which can be applicable to different solvents.
– Dry: for solid samples in powder form, which are dispersed by a current of air.

Technical specifications:

• Particle size: 10 nm – 3.5 mm
• Measurement principle: Mie and Fraunhofer dispersion
• Light source:

U6-E10. Nanosight NS-300 for Nanoparticle Tracking Analysis by fluorescence mode.

NanoSight NS300 – Malvern


The NanoSight NS300 uses nanoparticle tracking analysis (NTA) technology, which uses the properties of light scattering and Brownian motion to obtain measurements of concentration and size distribution of particles in liquid suspension.
A laser beam passes through the sample chamber, and suspended particles in the path of this beam scatter the light in such a way that they can be easily seen through a 20x microscope on which a camera is mounted. The camera runs at 30 frames per second and captures a video of the particles in their natural Brownian motion. The software tracks the particles individually and, using the Stokes-Einstein equation, calculates the hydrodynamic diameter of each of them.

Technical specifications:

• Size range: 10 – 1000 nm
• Concentration range: 106 – 109 particles/ml
• Temperature control range: 5º C below ambient to 50º C
• Minimum sample volume: 250 µl
• Camera: SCMOS
• Focus: Computer controlled motorized focus
• Fluorescence: 6-place motorized filter wheel, with filter options
• Wavelength:
– Blue: 488nm
– Green: 532nm


• Molecular and particle size distribution analysis.
• Concentration measurement.

Update of the Nanosight system

  1. The Green laser module for the NanoSight NS300 equipment.

The NS300 allows analysis of the size distributionand concentration of all types of nanoparticles from 0.01 – 1 µm in diameter. This new laser module will allow NTA to measure a range of fluorescent particles, avoiding interferences during the measurements due to sample (auto)fluorescence and absorption.  This is done by detecting the fluorescence signal, which is emitted naturally by particles or as a result of fluorescence labeling or tagging.
