Laboratory Products 45 The New PCR Instrument that Sends Status Emails
The Eppendorf Mastercycler nexus family of PCR instruments offer excellent reproducibility, low noise emission and the versatility to use all types of consumables. Up to three units may be combined for higher throughput, while software capability enables users to access a booking schedule for the instrument and receive email notification when the PCR cycle is finished. Low energy consumption and a small footprint add to the advantages of the Mastercycler nexus for both academic and industrial research laboratories. Designed to be affordable, flexible and reliable, the Mastercycler nexus incorporates Eppendorf’s flexlid™ concept with automatic height adjustment of the lid. In combination with the universal block this allows use of the widest variety of PCR consumables, from large 0.5mL tubes down to low profile plates and strips, and therefore a correspondingly wide range of reaction volumes. Excellent block homogeneity and temperature accuracy deliver highly reproducible results. The Mastercycler nexus gradient model provides a true gradient with 12 different temperatures and features SteadySlope technology to ensure that the heating and cooling ramp rates are identical in both optimisation and routine experiments.
With low noise emission, unrivalled at only <40 dB(A), the Mastercycler nexus will not disturb an environment where complex work is carried out. Energy efficiency is a further benefit: only 0.154 kWh are needed for a PCR and standby power consumption is 6 W. The small footprint and front-to-back ventilation system save space and allow units to be placed side-by-side. To increase PCR throughput one or two Mastercycler nexus eco modules (with no control buttons or display) may be connected to the Mastercycler nexus. According to Dr Kay Körner, International Senior Product Manager PCR: “The Mastercycler nexus is ideal for all PCR applications, from large volume to small volume, including emulsion PCR, in situ PCR, and low to high throughput. The combination of low noise levels, mainly due to less ventilation, with excellent temperature accuracy and high energy efficiency make the Mastercycler nexus a true masterpiece of engineering.”

Compact Foam-in-the- Bag System Without Drums or Containers
Storopack is introducing Foamplus Mini, a stand- alone table-top work-station, which dispenses PU foam cushions. The ‘foam-in-the-bag’ packaging system pursues an innovative approach: the foam components are directly inside the device and not in special drums or containers. This simplicity has also been adopted in operation. There is the choice of four bag sizes and five alternative filling amounts. The running operation functions without a cleaning procedure helping users to achieve minimal downtime.
With one component pack, the device can manufacture on average between 30 and 40 foam cushions. In order to refill it, the front cover is opened at the upper end of the system, and a new component pack is placed inside the system.
The compact construction of the Foamplus Mini allows the option of transferring the location in use: Mornings in the production department and afternoons in shipping - the versatility of the machine is possible because the system is lightweight and portable and only needs a standard 220 V power connection. For the user, this means simple ‘plug-and-play’ when packing.
PU foam cushions are a light, universally applicable form of protective packaging. The plastic molds to the individual contour of the product to be packaged as it hardens. The impact resistant cushions are able to overcome demanding transport situations thanks to their high level of resilience and rebound elasticity. Foamplus Mini also has a manual mode. The operator has an infinite number of bag sizes available for generating the PU foam cushions to pack particularly large articles. Storopack also offers equipment for pre- formed cushions to be used in standardised shipments. This application allows users to manufacture protective packaging in advance.
