Asynt Photo ReactorParallel photoreactor

Asynt has introduced a new modular version of its popular LightSyn Illumin8 photoreactor, an innovative system with the flexibility to change quickly and safely between a selection of high-power light emitting diodes (LEDs) operating at wavelengths including UV (365 nm) and blue (450 nm).

It allows chemists to run up to eight photochemical reactions in parallel using low-cost 8 mL tubes. Compact in size, it offers up to eight interchangeable modules of eight UV or coloured LEDs with safety interlocks to ensure light-tight photochemical reactions. With each high-power LED positioned close to a corresponding reaction tube, it delivers an even photon flux to each position, ensuring the consistency of photochemical reactions. Integral active cooling ensures reactions do not overheat.

Mounted on a standard magnetic hotplate stirrer, reactions can be agitated and heated up to 80°C. Connectors on the top allow for an inert atmosphere or vacuum to be applied to each reaction tube.

Biochromato Ion RocketMass spectrometry method

BioChromato has demonstrated how a thermal desorption and pyrolysis/direct analysis in Real Time-Mass Spectrometry (TDP/DART-MS) analysis method can reveal the thermal history of recycled thermoplastic resins.

Physical properties of thermoplastic resins such as strength and ability to elongate are known to degrade after repeated thermal reprocessing. It is important to have analytical methods that can quickly and reliably reveal the thermal history. Many traditional analytical techniques, however, fail to detect differences between virgin and recycled thermoplastic resins.

Using an IonRocket sample introduction device from BioChromato, it was confirmed that TDP/DART-MS can be a useful way to evaluate thermal history, by using the antioxidants contained in thermoplastic resins as a ‘thermal history marker’.

The ionRocket is a temperature-heating device for direct thermal desorption and pyrolysis of samples, prior to ionisation and analysis by mass spectrometry. A temperature gradient from ambient up to 600°C can be achieved in just a few minutes.

Testa Analytical Play and Plug Reactor ModulesMass flow from peristaltic pumps

TESTA Analytical Solutions reports its real time flowmeter can determine average flow rate as well as peak values of pulsation, enabling selection of the most appropriate setting for any peristaltic pump application.

Peristaltic pumps are used for a wide range of applications, from simple solvent transfer to more complex flow chemistries and lab scale reactions.

Carlo Dessy, Technical Director, TESTA Analytical, commented: ‘As simple and dependable as peristaltic pumps are, they do, however, come with drawbacks intrinsic to their design and principle of operation. The flow rate cannot be determined just by the physical dimensions of the peristaltic wheel and tubing and its speed of rotation. Other factors including the viscosity of the transported liquid, flow pulsations, back pressure and ageing of the pump tubing have a significant influence.

Compact and powered via a USB connection, the flowmeter uses a thermal flow sensor that is not only extremely accurate, sensitive, and high-resolution, but is non-invasive.

Uniqsis peristaltic pumpsPlug and play reactor modules

Uniqsis offers affordable ‘plug and play’ reactor modules designed to make high performance flow chemistry accessible.

With an operating temperature range of ambient to +300°C, the HotCoil reactor heating module represents a cost-effective entry solution into flow chemistry, simply add pumps. With LED display and ‘push-to-set’ controller, it is ideally suited to stand-alone operation. Alternatively, it can be controlled by the Uniqsis FlowSyn, Binary Pump Module, or FlowControl software.

HotChip is a standalone heater module that provides precise temperature control of flow chemistry glass static mixer (GSM) chip reactors. The Uniqsis borosilicate glass chip reactor blocks can be used as static mixers or to perform fast exothermic reactions.

The Cold Coil II flow reactor module provides an entry-level solution for low temperature flow chemistry. With an external thermoregulation circulator it can maintain stable temperatures between -78°C and +150°C for extended periods. A glass cover eliminates convective effects; a vacuum jacketed glass cover is also available.
