21 CFR 11 UV And FL Solutions Software Announced
Lambda Advanced Technology is delighted to announce the availability of 21 CFR Part 11 versions of the respected UV Solutions and FL Solutions control software.
The speedwave MWS-2 and MWS-3+ digestion units utilise microwaves to directly heat the sample, giving reduced digestion times and significantly higher sample throughput rates.
The Digestec range of pressure digestion systems is available for extended digestion periods at high temperatures and pressures for even the most difficult samples such as SiC and alpha Al2O3.
For routine applications, the speedwave MWS-2 provides a versatile approach to digestion with an average digestion time of 15-20 minutes.
The compact unit operates up to a temperature of 220 deg C and offers a choice of sample numbers and volumes, from 5 sample vessels at 70 ml and 100 bar to 24 vessels at 10 ml and 75 bar.
A contact- free IR measurement system measures the actual temperature of the samples in individual vessels rather than the external vessel temperature.
For the most sophisticated digestion control, the speedwave MWS-3+ unit uniquely features a contact-free temperature measurement system and a patented contact-free pressure measurement system for all of the sample vessels.
These novel methods of temperature and pressure control increase both user safety and the reproducibility of the digestions.
Since no sensors need to be connected to the pressure vessels, sample handling is greatly simplified.
The MWS-3+ unit is configured to accommodate 12 sample vessels of 30, 60 or 80 ml volume or 8 vessels of 100 ml volume.
A maximum temperature of 260 deg C and operating pressures of up to 150 bar increase the range of digestions that can be performed.
Digestec DAB pressure digestion systems consist of stainless steel pressure digestion vessels with a TFM PTFE liner.
Available in capacities from 10 to 250 ml, the systems can be operated at pressures up to 200 bar and externally heated to temperatures up to 250 deg C.
Equipped with a pressure relief device, these systems can be used over whatever time period is required to complete the dissolution. Request a free brochure from Lambda Advanced Technology ...
