Entrambi spendono una barca di soldi per farsi pubblicità sul web http://modernhomesleamington.co.uk/component/k2/itemlist/user/315?format=feed puntando sul fatto che puoi guadagnare At the hearth of the UltraWAVE is a Teflon-lined 1 liter stainless steel reaction chamber, which serves both as a microwave cavity and a reaction vessel.
Samples are weighed into vials, and suitable reagents are added. Vials are placed in a rack, which is automatically lowered into the reaction chamber. The chamber is sealed and pre-pressurized with inert gas, which physically acts as a cap for the vials, avoiding boiling of the solutions and preventing cross contamination.
At the completion of the microwave run, a built-in cooling device rapidly lowers the temperature.

http://inter-actions.fr/bilobrusuy/2538 The UltraWAVE operates up to 199 bar pressure and 300°C. Unlike all conventional microwave digestion systems, every sample is under direct temperature and pressure and temperature control- no needs to rely on a reference vessel or to an indirect control such as infrared temperature sensors.
This assures complete control of the digestion process in every sample.
All sample types are digested at the same temperature and pressure even with different acid mixtures and volumes.
Moreover the UltraWAVE thanks to the Automatic Gas Module further improves the lab throughput.

The PID controller monitors pressure, digestion and chamber temperature 20 times/sec, adjusting microwave power to control even highly exothermic reactions.
opcje binarne najmniejszy depozyt At the completion of the microwave run, the UltraWAVE built-in water cooling device enables the temperature to lower from 270°C to 80°C in just 12 minutes.
Once the system reach the set cooling temperature, automatically releases the pressure from all the vials simultaneously.
http://weselny-duet.pl/visre/pieor/396 No vessel assembly/disassembly is required, vessel cleaning is eliminated with disposable glass vials, and method development is virtually eliminated.
There are also major savings on consumables costs, which is important for high throughput labs using closed vessel digestion.
Racks from 4 to 22 positions are available with vials made of quartz, PTFE/TFM or disposable glass vials, in order to match even very low blanks level.
Ask to your local Milestone Specialist the best configuration for your needs.
here The UltraWAVE is operated via a compact control terminal with easy-to-read, bright, full-color, touch- screen display.
Hundreds of applications, including all US EPA methods, are preloaded in the UltraWAVE terminal.
The terminal is provided with multiple USB and RS-232 ports for direct printout of microwave methods and runs, and for interfacing the instrument to external peripherals.
The terminal runs the Milestone’s unique multi-language EasyCONTROL software, to provide simple, user-friendly control of the microwave sample preparation process. Simply recall a factory-stored method or create a new one; press ‘START’ and the system will automatically follow the user defined temperature or pressure profile, utilizing a sophisticated PID algorithm to regulate the microwave power.
