U6-S12. Packed (tapped) density (On-site) OUTSTANDING

Packed (tapped) density

Each particle of a solid material has effectively the same true density regardless of size or shape, but more or less geometric space is occupied by the material according to the relative particle-particle cohesion and mechanical interference. That is, the apparent bulk densities of powdered, granular or flaked materials are highly dependent on the manner in which the particles are packed together. Furthermore, handling or vibration of particulate material causes the smaller particles to work their way into the spaces between the larger particles. The geometric space occupied by the powder decreases and its density increases; ultimately no further natural particle packing takes place without the addition of pressure and maximum particle packing is achieved.
The equipment for this purpose is Autotap (Quantachrome Instruments).

The equipment provides tapped density measurements of powders for customers who need to characterise this property and add value to their materials.

U6-S05. Freeze dryer

Freeze dryer

Freeze drying (also known as lyophilization) is a water (or other solvents) removal process typically used to preserve materials, with the goal of extending their shelf life or reducing 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:

  1. Freezing: 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.

U6-S07. Interactions of two biomolecules with respect to binding kinetics and affinity by surface plasmon resonance (SPR).

Interactions of two biomolecules with respect to binding kinetics and affinity by surface plasmon resonance (SPR).

Technically speaking, SPR refers to an optical phenomenon that enables monitoring of changes in refractive index via a quantum mechanical principle.

In a traditional SPR experiment:

  • A target is immobilized or captured onto a surface known as a sensor chip.
  • A pump is used to flow analytes over the sensor chip.
  • An optical measurement system captures changes occurring on the surface of the sensor chip.
  • Software plots time-dependent responses in the form of a graph called a sensorgram.

Customer benefits

With SPR, you can determine the rates and affinity of interactions between biomolecules and answer multiple questions using a single instrument.
SPR is the gold standard for analyzing biomolecules, providing:
High quality kinetics (association and dissociation constants, plus equilibrium)

  • Real-time data acquisition.
  • Label-free analysis.
  • Faster, automated experiments.
  • Lower sample consumption.

SPR’s flexibility lets you study biomolecular interactions in a wide variety of analytes, from small molecules in drug discovery to peptides, proteins, DNA, viruses, and even whole cells. SPR allows for:

  • Simple yes/no binding
  • Equilibrium studies
  • Complex kinetic analyses

U6-S08. Tangential flow filtration

Tangential flow filtration

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.

Customer benefits

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.

Target customer

  • Pharmaceutical industry
  • Food Industry
  • Chemical industry
  • Materials research centers

U6-S02. High-pressure phase analysis – solubility, emulsification (Remote) OUTSTANDING

High-pressure phase analysis – solubility, emulsification.

This phase equilibria unit is built for the measurement and detection of phase equilibria and phase transitions by optical means.
The mixture of solute and solvent gas is agitated by the magnetic stirrer. Whenever samples are drawn from the top or the bottom connection in the cell, the directly connected counterbalance piston moves towards the centre of the cell, this keeping the pressure in the measuring cell constant even during the sampling operation. No need to add additional solvent gas, which would change mass ratio and temperature and consequently result in a disturbed equilibrium.

Customer benefits

• Capacity: 29-55 mL (depending on piston position)
• Operating pressure max.: 200 Bar
• Operating temperature max.: 150 °C

Counterbalance piston to maintain constant pressure during sampling operation

• Optical path length: 58 mm
