17 Sample Preparation & Processing LED photoreactor for larger batch reactions
Uniqsis presents the Solstice Maxi™, a cutting-edge LED photoreactor designed to accommodate twelve 20ml cm3 septum-sealed reactor tubes in a jacketed, multi-position tube holder. Engineered for scientists aiming to scale up batch photochemistry reactions, the Solstice Maxi™ seamlessly integrates with a standard laboratory magnetic stirrer, ensuring efficient stirring of each tube’s contents.
Maintaining photochemical reactions at a fixed temperature is effortless with the Solstice Maxi™. By connecting it to a recirculating liquid coolant, precise temperature control (10 – 60ºC) is achieved. While a piped water supply is an option, enhanced temperature control is guaranteed through connection to a recirculating heat exchanger.
With the insertion of a Borealis high-power LED lamp unit (365nm, 385nm, 425nm, 440nm, 460nm or 525nm), positioned at the centre of the Solstice Maxi™, the system transforms into a versatile, temperature-controlled, multi-position photoreactor. An embedded temperature sensor measures the LED back-plate temperature, ensuring automatic detection and configuration of LED wavelength and electrical parameters when connected to the matching ‘smart’ power supply. For precise control over photochemical reactions, the power supply enables LED intensity variation in 5% increments from 10-100%.
The Solstice Maxi™ is powered by a digital power supply unit, offering remote control and displaying both the internal reactor and LED backplate temperatures. Although primarily designed as a batch photoreactor, the Solstice Maxi™ can be adapted for continuous flow processing by combining the lamps with a Uniqsis Cold Coil and internal coil reactor, adding further versatility to this advanced device.

Precision repeat dispensing at your fi ngertips
The Socorex Stepper™ is a compact and reliable instrument intended for serial dispensing within volumes from 10 to 5000 µL. Associated with only three Ecostep™ positive displacement syringes, it provides a broad choice of 53 different volumes, and up to 73 aliquots per filling.
Its unique four-finger activation eliminates thumb fatigue. This enables smooth monitoring of each step, whatever the pipetting speed.
There are three interchangeable setting knobs, bearing volumes and corresponding number of aliquots. Volume selection is easy and quick, with a clear reading of the adjustment chosen. The colour codes on both syringes and setting knobs eliminate any risk of wrong use. A graduation on the syringe helps monitoring liquid content. If remaining liquid in the syringe is smaller than the selected aliquot volume, the built-in self-locking mechanism stops distribution to prevent false delivery.
Stepper™ offers a great flexibility in use, fitting well in many laboratories performing repeat dispensing tasks such as screening procedures, dividing samples in small portions, or dispensing reagents in vials. And the very fine syringe tip end facilitates distribution in narrow tubes.
The positive displacement Ecostep™ syringes avoid any direct liquid contact with instrument, thus limiting contamination with chemicals such as acids, bases and solvents. Syringes are also efficient for the distribution of foaming liquids as well as viscous and high-density reagents.
The Stepper™ repeater pipette has a very long lifespan, well matching with today’s concern to limit impact on the environment. There is no battery to change, nor electronic parts to recycle. For further details check the website or contact your closest Socorex distributor.

62490pr@reply-direct.com Optimising seal quality and manufacturing workfl ows
Azenta Life Sciences has prepared an informative new video demonstrating the walkaway productivity achievable using its Automated Individual Access Roll Heat Sealer in molecular diagnostics, drug discovery and kit manufacturing applications.
The new video illustrates key benefits of the Automated Individual Access Roll Heat Sealer that include operational flexibility, reproducible sealing, intuitive operation and plug-and-play robotic integration.
This unique automated heat sealer can seal individual wells or tubes, enabling researchers to leverage the benefits of the Azenta Individual Access plate and seal range while maintaining the gold standard heat sealing provided by the device.
The Individual Access plate and seal range is based upon a plate design with individually removable wells, together with seals consisting of individual foil seal spots. Individual sealing enables selection and removal of tubes from the plate and is a flexible solution with the ability to also seal custom shapes with custom seals.
The high sealing pressure and accurate time and temperature controls used by Automated Individual Access Roll Heat Sealer deliver reproducible seal uniformity on a wide range of microplates.
User set-up is via a colour touch screen with intuitive user interface. To aid productivity, the Automated Individual Access Roll Heat Sealer provides the facility for saving password protected protocols and SOPs containing set temperatures and times.
Offering the versatility to be optimised for almost any sample integrity maintenance application – the instrument is ‘plug and play’ connectable with other instruments, such as readers, robotic arms, and liquid handlers, to give a custom automated system without the need to write expensive custom drivers.
