71 Sample Preparation & Processing New Options Increase Versatility of High Pressure Parallel Reactor
The Asynt MultiCell is a lightweight, high pressure parallel reactor designed for undertaking experiments including carbonylation, hydrogenation, catalysis and supercritical fluid reactions as well as air sensitive material studies. Used in conjunction with a hotplate stirrer the standard 316 stainless steel MultiCell reactor offers users the ability to undertake 10 x 30 ml reactions in parallel at pressures of up to 50 bar and temperatures up to 200°C.
In response to customer requests - Asynt has developed a range of new features and options for the MultiCell high pressure parallel reactor that further increases the versatility of this high performance system. These new options include a system capable of operating up to 350°C and 200 bar; a 4-position system offering reaction volumes of up to 150ml; the ability to make additions / take samples under pressure; sub-ambient reactor cooling and the ability to have different temperature and pressure in each reactor cell.

Planetary Mill with a Variable Transmission Ratio
In contrast to conventional Planetary Mills, the rotational speed of the grinding bowls and supporting disk can be configured separately in the Vario-Planetary Mill PULVERISETTE 4 classic line with 2 working stations from Fritsch GmbH. This results in a single mill for mechanical activating and alloying providing optimum grinding conditions suited to the respective material to be ground and the size of the grinding bowls and balls.
The PULVERISETTE 4 classic line also operates according to the Planetary Principle, but the transmission ratio between grinding bowls and supporting disk is variable adjustable. This means you can directly influence the movement and paths of the grinding balls: depending on the setting, you can obtain high impact energy or high friction, according to your needs, or have your PULVERISETTE 4 classic line operate as a Centrifugal Mill. You are free to choose all intermediate levels and combinations between friction-based and impact-based comminution.
Features include: flexible configurable grinding conditions: impact and/or friction; rotational speed up to 400 rpm; ideal for mechanical alloying and activation; simultaneous processing of up to 4 samples; especially suited for material research and development applications; ultimate fineness down to 0.1 µm; useful capacity of 2 x 0.5 ml to 2 x 225 ml; bowl sizes 12 ml, 45 ml, 80 ml, 250 ml and 500 ml capacity.
The Vario-Planetary Mill PULVERISETTE 4 classic line can be combined with the GTM-System for measuring of the gas pressure and temperature during grinding. This turns your mill into an analytical measuring system.

New Automatic Melting Point System with Digital Video Technology for Walk-Away Recording of Sample Melting Launched
Bibby Scientific Ltd have announced that Stuart®, a leading UK manufacturer of bench-top laboratory equipment, has launched the SMP50, a new automatic melting point system that incorporates high resolution video technology combined with an intelligent melt algorithm to determine the melting point of up to three samples, simultaneously and automatically. The SMP50’s digital camera also records the sample melt, providing confirmation of the automatically-obtained result and time-stamped video files that can be easily transferred to a PC for long- term proof of measurement and traceability.
This latest addition to Stuart’s leading range of Melting Point products can be trusted to measure sample melting points automatically, through monitoring and identifying small changes in the sample. Its accurate and reliable capabilities save valuable time and labour for scientists while conforming to Pharmacopeia and GLP standards. The system’s user-interface is based on the well-known Android platform, making it highly intuitive to set up and navigate, with a logical layout and easy access of common tasks from the home screen.
The SMP50’s functions include rapid ramp mode, for quickly scanning through the entire temperature range (at 20ºC per minute) when working with unknown plateau temperatures. “Stuart has been instrumental in making the automatic melting point a commonplace piece of laboratory equipment,” said Jackie Taylor, Product & Marketing Communications Manager at Bibby Scientific. “The new SMP50 is built on cutting-edge, intelligent technology that fully automates melting point measurements in a simple, compact and user-friendly unit that’s suitable for labs of all sizes.” All operation is via the 7-inch high-definition colour touchscreen and, once programmed, users can walk away from the system and leave it to complete the melt analysis independently. Alternatively, melting can be observed live on-screen, or through watching the video recording post-melt; up to 300 melt files can be stored in the system’s 8GB memory.
