Microwave Closed Vessel Digestion System UltraWAVE
Benchtop Single Reaction Chamber (SRC) Digestion System
SINGLE REACTION CHAMBER (SRC) DIGESTION IN A BENCHTOP PACKAGE
The Game Changer in Microwave Digestion
Milestone’s unique Single Reaction Chamber (SRC) technology, first developed with the UltraCLAVE, overcomes the limitations of traditional microwave sample preparation.
At the heart of the system is a large sample chamber that is pre-pressurized with inert gas and heated with microwave energy. The chamber serves both as a microwave cavity and a reaction vessel. Employing the same SRC technology as the UltraCLAVE, the UltraWAVE offers the same great benefits, but in a smaller benchtop instrument, making it accessible to every lab. With higher performance, higher sample throughput, improved workflow, plus lower labor and consumables costs when compared with conventional closed vessel systems, the UltraWAVE is transforming microwave digestion. And not only microwave digestion: its higher sample weight capability, greater digestion power, outstanding throughput and ease of operation means UltraWAVE can replace open vessel digestion, high pressure ashing and even block digestion in many applications.
UltraWAVE Key Benefits
Greater Ease of Use
Compared to closed vessel digestion, the UltraWAVE is significantly easier to use and workflow is dramatically improved. No assembly/disassembly of vessels is required, and no vessel cleaning (with disposable glass vials). Direct temperature and pressure control of every sample ensures complete control of the digestion process. Any combination of sample types can be digested simultaneously; no need to batch samples into identical types. No method development is needed (the same method can be used for almost every sample type) and no need to use different rotors for different sample types. And for the first time, reference standards (any matrix) can be digested alongside samples, enabling true in-run digestion QC.
Compared to closed vessel digestion, labor costs are significantly lower because no vessel assembly/disassembly is required, vessel cleaning is eliminated with glass vials, and method development is virtually eliminated. There are also major savings on consumables costs, which can be significant for high throughput labs using closed vessel digestion.
Lower Operating Costs
The UltraWAVE has higher sample throughput than closed vessel digestion, even where closed vessel systems are used with high capacity rotors, due to quicker sample loading/unloading and shorter cool down time. And since there is no need to batch samples into identical types for digestion, workflow is significantly improved.
Capable of operating up to 199 bar pressure and 300°C, the UltraWAVE enables complete digestions for virtually every sample type, outperforming any other microwave digestion system. The high pressure capability, and powerful microwave source enables higher sample weights to be digested. For example up to 2g of infant formula can be digested, 2-3 times higher than is possible with a high pressure rotor with closed vessel digestion, and very useful to labs at the limit of ICP-OES detection. Blanks are significantly lower than with closed vessel digestion, since less solution transfer occurs, quartz vials can be used and digestion acid volumes are lower.
Fields of Application
Volatile analytes are not lost during digestion using the UltraWAVE. Environmental labs that have traditionally used block digestion are now finding they can recover volatile analytes successfully with UltraWAVE.
Food and Feed
The ability to digest higher sample weights than any closed vessel system allows UltraWAVE to digest up to 2g of sample, replacing open vessel digestion systems and dry ashing in busy food labs.
Consumer products testing
With the UltraWAVE, consumer products testing labs can batch many different sample types together for simultaneous digestion, greatly improving the digestion workflow.
The ability to digest different sample types in a single batch, no loss of volatiles and very low digest acid volume makes UltraWAVE the perfect partner for ICP-MS in clinical labs.
In pharmaceutical testing, unknown, high organic content samples necessitate the use of high pressure vessels with closed vessel digestion. The UltraWAVE can handle pharmaceutical samples with ease.
When testing materials for ROHS directive compliance, the UltraWAVE can digest the entire range of sample types subject to regulation. Its ability to digest mixed batches greatly increases productivity.
At the heart of the UltraWAVE is a Teflon lined, 1L stainless steel reaction chamber, which is also the microwave cavity. This allows the design of the1500W microwave source to be perfectly matched to the cavity shape for optimum microwave distribution and fast, even heating. Samples are weighed into vials and placed in a rack, which is lowered into the reaction chamber. The chamber is sealed and pre-pressurized with inert gas, which acts as a “cover” over the samples, preventing cross contamination. Unlike closed vessel digestion, different sample matrices can be digested together, and the chamber is water cooled, which makes cool down time very fast.
Like all Milestone products, the UltraWAVE has been designed with operator safety of paramount importance. A thick acrylic shield surrounds the work area, which lowers into position automatically as the chamber is closed. A run can not be started unless the chamber clamp is in position, and the clamp cannot be released until the chamber is cool, and pressure has been released. The PID controller monitors pressure, digestion and chamber temperature 20 times/sec, adjusting microwave power instantaneously to control even highly exothermic reactions.
Performance and Control
The UltraWAVE is an ultra high performance system, operating up to 199 bar pressure and 300°C, and ensuring complete digestion of even the most difficult samples. And unlike closed vessel digestion, every sample is under direct pressure and temperature control; no need to rely on indirect control such as infrared temperature sensors. This assures complete control of the digestion process in every sample. No need to use a reference sample, and no venting of vessels due to over pressure. The UltraWAVE reaches temperature faster, cools faster, and is capable of higher pressure and temperature than any closed vessel system.
Available sample rack configurations include 4, 5 and 15 position, plus a 22 position rack for microsamples. Vials are available in glass (disposable), quartz or TFM, and are fitted with Teflon caps, loose fitting to ensure pressure equalization. Numbered rack trays give the operator an easy visual check of vial number. UltraWAVE sample racks fit easily on a balance, so samples can be weighed directly into vials already loaded into a rack. Unlike closed vessel digestion, no vessel assembly or disassembly is required, and with disposable vials, no cleaning step is needed, greatly increasing productivity.
The UltraWAVE is operated via an industrial grade control terminal featuring a full-color 6.5” touch screen display. The terminal runs Milestone’s renowned EasyCONTROL software, common to all our digestion instruments. EasyCONTROL enables simple and intuitive, but extremely flexible and powerful control over the digestion process. Digestion method setup could not be simpler: set target temperature, ramp time and hold time. Press ‘Start’, and the system automatically follows the temperature program, continuously varying the microwave output via a sophisticated Proportional Integral Derivative (PID) controller.
Unlike other digestion systems, the operator is not required to set the power level. UltraWAVE’s PID controller automatically applies the require microwave power to follow the desired temperature profile regardless of sample weight or number of samples in the run. EasyCONTROL has full audit trail capability plus multi-level user access security for compliant environments: each operator has a personal password to access the software. EasyCONTROL can generate sample run reports, combining the microwave program with sample weights and reagent volumes. Sample weight can be imported automatically into the run data file by connecting a balance to the terminal via a serial port. Run data is stored on a flash drive or USB memory stick and can be transferred to a PC with optional EasyDOC software
