Electrophoresis Product Range Expanded
Cleaver Scientific announces an addition to its electrophoresis product range. The range now includes the compact CSL multiSUB Midi 96 and 96 Stretch system which can be used in conjunction with samples from 96 well plates to allow direct loading and easy identification of samples.
With an average run-time of just 15 to 30 minutes, the Midi 96 system enables rapid identification of samples, with direct and rapid sample loading facilitated using 8 channel pipettes. Four comb options are available – 8MC with 1 or 2 marker lanes in 1 or 1.5mm thickness.
The run length between lanes is 1.8cm for the MSMIDI96 version and 3.6cm for the Stretch version. The Stretch version also has the capability for increased capacity allowing samples from two Micro titre plates to be loaded.
Flexibility and choice are among the key features of the CSL range of gel electrophoresis tanks which comprises horizontal and vertical gel electrophoresis tanks, blotting systems, comet assay, cellulose acetate, 2-D systems, power supplies, DNA sequencers and gel documentation systems. These are suitable for a variety of DNA, RNA and protein gel electrophoresis applications and analysis.
Constructed using the latest injection moulding technology and made from durable, resistant materials, the tanks offer innovative and easy-to-use leak-proof gel casting to save time in the laboratory.
Among the innovations and choices offered are more options for gel size, sample number and volume, along with five thicknesses of comb. Also, there are more preparative, high sample number and multi- channel pipette compatible comb options and combs, which are height adjustable and warp proof.
There are also options for the type of comb with convenient double-sided, two combs in one and combination combs, which include a loading guide on the reverse aiding sample loading.
Gel sizes offered range from 7cm x 7cm up to 33cm x 45cm. Cleaver Scientific also offer many other options to enhance the visibility of the wells during gel loading, such as using an inert dye which is used to stain the stacking layer of protein gels.

New Whitepaper on Reactor Temperature Control from Huber
Huber has produced a new 14 page whitepaper showing the effects of good heat transfer on the process under all conditions. Huber revolutionised the world of temperature control in 1989 with the introduction of Unistat technology and the new whitepaper aims to provide information about temperature control systems drawn from Huber’s vast experience in the field of thermal dynamics.

The Whitepaper provides information on:
• Thermal dynamics – The effects of pressure and flow on thermal transfer
• Centralised Systems – Achieving better control for large volume production reactors
• Environmental commitment – Reduced energy consumption and natural refrigerants.
• Case studies – Precision cooling at low temperatures, control of exothermic reactions and temperature cycling

When cultivating microorganisms in Erlenmeyer flasks on a vibrating board, the oxygen intake is frequently the limiting factor for cell growth. In standard Duran Erlenmeyer flasks, a liquid sickle forms, the size of which depends on the speed of the board and the vibration diameter. The larger the surface of the content, the larger is the gas exchange surface and with it the possible oxygen intake.
The speed and the associated oxygen intake only increase in a limited manner. The new Duran Erlenmeyer flask with four baffles on the bottom interrupts the laminar flow to create a turbulent flow. The surface of the liquid and the gas exchange surface is increased, so that the oxygen intake can be increased. Laboratory tests showed that the oxygen intake could be doubled due to the chicanes in contrast with the standard Duran Erlenmeyer flasks.
Due to completely automated machine manufacturing, the Erlenmeyer flasks with baffles from the Duran Group are geometrically reproducible. The wall thickness of the flasks has been increased to achieve excellent mechanical strength and to guarantee a long product service life. The flasks can be sealed with the reusable Duran Group membrane cap. This enables reproducible gas exchange in contrast with other closure options, such as sealing with cotton wadding or similar.
