U6-E11. Turbiscan Lab

Turbiscan Lab

Description: Turbiscan is used to detect at an early stage all kinds of destabilisation such as coalescence, flocculation, creaming, sedimentation, etc… Various products such as emulsions, suspensions or foams can be studied from low to high concentrations without any sample preparation or dilution. Stability kinetics and index are measured for an efficient sample analysis and comparison.

Applications: Stability studies

Kondo effect in a neutral and stable all organic radical single molecule break junction

It is shown that the paramagnetism of the polychlorotriphenylmethyl (PTM) radical molecule in the form of a Kondo anomaly is preserved in two- and three-terminal solid-state devices, regardless of mechanical and electrostatic changes. Indeed, reported evidences demonstrate that the Kondo anomaly is robust under electrodes displacement and changes of the electrostatic environment pointing to a localized orbital in the radical as the source of magnetism. Strong support to this picture is provided by DFT calculations and measurements of the corresponding non-radical species. These results pave the way towards the use of all-organic neutral radical molecules in spintronics devices and open the door to further investigations into Kondo physics.

U6-E03. Four Glove Dispensing isolator for expermiments with highly active and cytotoxic compounds

Four Glove Dispensing isolator for expermiments with highly active and cytotoxic compounds.

Description: The four-glove isolator is a safe chamber, with controlled environment for the weighing and handling of potent drug compounds.

Technical specifications: The Isolator has been designed to offer containment to a working OEL (Occupational Exposure Limit) of less than 0.1Jgrams/m³ time weighted average over an 8hr operational period (TWA).

The Isolator is designed to offer an internal air cleanliness of Class 8 as described in ISO 14644-7 and the test pass criteria is a leakage rate of ≤0.25% vol/hr and is in line with Class 2 classification of ISO 14644-7.

  • Internal Environment: – Main Chamber: -100Pa +/- 10%.
  • Air Changes per hour: Nominal 20 during normal operating conditions giving ISO 8.
  • Glove Breach Velocity: >0.5m/sec.
  • Exhaust System: Max air flow 108m3/hr.
  • Inlet HEPA Filter: H14 Canister (safe-change when changed into Isolator). 99.995% efficient @ 3Jm particle size.
  • Exhaust HEPA Filter: 1st Stage – H14 HEPA & 2nd Stage – H14 HEPA mounted within Push-Push Safe Change housing 99.995% efficient @ 3Jm particle size.

Applications:

Pharmaceutical Manufacturing: In pharmaceutical manufacturing, especially for the production of potent drugs or active pharmaceutical ingredients (APIs), a 4-glove isolator can be used for containment. It helps in preventing cross-contamination and ensures the safety of both the product and the operator.

Biotechnology Research: In research laboratories working with hazardous biological materials such as viruses, bacteria, or genetically modified organisms (GMOs), a 4-glove isolator provides a secure environment for manipulation and experimentation. It minimizes the risk of exposure to harmful agents.

Sterile Compounding: In compounding pharmacies and hospital pharmacies, a 4-glove isolator can be utilized for sterile compounding of medications. It helps in maintaining aseptic conditions, preventing contamination, and ensuring the safety and efficacy of compounded drugs.
