U6-E09. Nanosight LM -20 for Nanoparticle Tracking Analysis

Nanosight LM -20 for Nanoparticle Tracking Analysis.

Description: Particle size distribution (from 10 to 1000nm) and particle concentration by real-time visualization of nanoparticles in a liquid

Technical Specifications:

Nanoparticle analysis range: typically 10 nm – 1000 nm, dependent on particle material

Particle type: any

Solvent: any non-corrosive solvent and water. A range of solvent-resistant seals are available.

Sample volume requirements: 0.3 ml

Applications: Particle size distribution and particle concentration by real-time visualization of nanoparticles in a liquid. In addition to biological samples also paints, pigments, sun creams, inks, metals, metal oxides or fuel additives in any non-corrosive solvent and water can be examined with virtually no sample preparation.

U6-E06. Malvern Zetasizer Nano ZS particle size analyzer

Malvern Zetasizer Nano ZS particle size analyzer.

Description: The Zetasizer Nano ZS is a molecular and particle size, surface charge, and molecular weight measurement system based on static light scattering (SLS), dynamic light scattering (DLS), and electrophoretic light scattering (ELS). ). These are rapid, accurate and repeatable measurement methods that do not require large sample volumes and are non-destructive.
SLS determines the molecular weight from different concentrations of a sample by applying the Rayleigh equation.
DLS uses the Brownian motion of particles, which move randomly in a liquid. Through established theories, the speed of diffusion is related to size.
ELS combines light scattering with electrophoresis, converting electrophoretic mobility into a measure of zeta potential.

U6-E02. High-pressure phase analyzer for studying the thermodynamic behaviour of materials

High-pressure phase analyzer for studying the thermodynamic behaviour of materials

Description: Stainless steel vessel equipped with a sapphire windows for visual observation inside the vessel.

The equipment allows for a wide range of phase analysis, such as solubility and miscibility studies, with solids, liquids and gases at different range of pressures, up to 150 bar.

The vessel is equipped with a moving piston, driven by nitrogen at high pressure. The moving piston allows for a change in the effective volume of the vessel, allowing you to increase or decrease the amount of material inside the chamber during the phase analysis while maintaining isobaric conditions.

Technical Specifications:

• Capacity: 29 to 55 mL
• work pressure: 150 bar
• work temperature: 50º C
• Material: 316 Stainless steel
• Gas: Nitrogen

Aplications:

• Analysis of phases
• Studies of solubility and miscibility

U6-E01. High-pressure laboratory-scale plant with 50, 100 and 300 ml reactors for the processing of biomaterials

Description: The lab-scale high pressure equipment used to process materials with compressed fluids (i.e. CO2, ferons)

Technical Specifications: Lab-scale high pressure systems, based on a 50mL, 100 and a 300mL stirred high pressure autoclaves equipped with pumps for the supply of compressed fluids and liquid solutions, respectively. Both plants could also optionally be equipped with several filters, manometers, thermocouples and back pressure regulators. The maximum operative pressure is 23MPa and the maximum operative temperature is 200ºC.

The 300mL system is also equipped with a mass flow meter, and a data acquisition system.

The plants have been designed for micro- and nanostructuring molecular and soft materials.

Particulate polymeric matrix uniformly loaded with active compounds (therapeutics, cosmetic ingredients, catalyst, pigments and dyes, etc..)

Dispersed systems (suspensions, liposomes, emulsions, vesicles,) with narrow particle size distribution and high morphological homogeneity.

Porous materials, either crystalline or amorphous, with defined porosity and porous size.
