documentation. The validation of processes will become ever more significant, which is why suitable software solutions will have to be available to meet these requirements. Today the INCO2 is already fitted in its standard form with a whole series of convenient and time saving functions and interfaces for programming, data storage and the documentation of processes.


ELECTROPOLISHING: SMALL CAUSE, LARGE EFFECT


The surface roughness of conventional stainless steel can neither be felt with the fingers nor seen with the bare eye. And yet in some circumstances they can provide a large surface for germs only a few micrometers in length. For working with biological materials the


stainless steel chambers of all Memmert CO2 incubators INCO2 are therefore additionally smoothed by electrolysis for working with biological materials – a procedure that is standard in the manufacture of medical instruments, in order to remove the micro roughness on the metallic


surface. At the same time the corrosion resistance of the metal is increased by this procedure. For the employees in the laboratory, cleaning and disinfection are also simpler due to the extremely smooth surfaces, and considerably more effective with respect to hygiene.


HUMIDITY CHAMBER HCP AS AN ALTERNATIVE TO THE INCO2


Even if the currently valid DIN EN ISO 11731-2:2007 no

longer stipulates that samples must be fumigated with


CO2, it does announce a recommendation to the extent that carbon dioxide can promote the growth of certain


legionellae. For laboratories that do not use CO2, the Memmert humidity chamber HCP represents a comparable alternative to the INCO2. This also offers all the advantages of the INCO2 mentioned above, such as sterilisability, safety and controllability - the rH concentration can be set via the active humidity control between 20% and 95%.


Progressive flattening of a metal surface through electropolishing


Element unit. Designed for use with the Milli-Q®


Integral and Milli-Q Advantage systems from Millipore, the device ensures delivery of ultrapure water with extremely low levels of elemental contamination (single ppt or sub-ppt level) for laboratories performing trace and ultra-trace elemental analysis.


By eliminating problems due to backgrounds with high elemental contamination, water produced by the Q-POD Element device can help scientists achieve greater sensitivity and reproducibility in their work. Ultrapure water with minimum elemental contamination is typically required for use in blanks, standard solutions, sample dilutions and plasticware rinsing by researchers working with IC, ICP-MS and GF-AAS analytical instruments.


“With elemental contamination levels of between 10-100 times lower than any other product on the market, Millipore’s Q-POD Element unit will help move ultra-trace elemental analysis to new levels," said Jean-François Pilette, Millipore Lab Water Group Product Manager. "It is the most advanced solution available today for production of ultrapure water with the lowest elemental trace contamination— at high flow rate—and at a reasonable cost,” he added.


Equipped with a footswitch for hands-free water delivery, the Q-POD Element unit is ideal for use in a Class 1000 clean room environment. The unit supplies water in the volumes required by the user (up to 1.5L/min), which avoids water storage as well as the associated contamination risks. Scientists working under a Class 100 laminar flow hood can activate delivery with the footswitch and seamlessly continue their work without stopping to dispense ultrapure water manually.


Q-POD Element water quality was verified by independent laboratories specialising in ultra-trace analysis. These validation test results are available upon request. Circle no. 425
