Detect Dengue From the First Day Fever Appears
Inverness Medical has announced the launch of the new Panbio®
Dengue Early Rapid
immunochromatographic test for the early detection of dengue infection. Designed for use in conjunction with other dengue serology tests, the
Dengue Early Rapid test can help to diagnose active dengue infection from the very first day fever appears. In facilitating early diagnosis, therapy and monitoring can begin much earlier, reducing the risk of severe complications such as dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS).
Detecting dengue NS1 antigen in serum, the Dengue Early Rapid test is able to provide a specific diagnosis of dengue infection in 15 minutes following an easy three step procedure. This is especially valuable in areas where diagnosis could be confounded by serological cross reactivity. There are four distinct dengue virus serotypes (DEN -1, -2, -3, -4) which are immunologically related and can all cause dengue fever. Although related, the four serotypes do not provide cross-protective immunity against each other, resulting in patients in endemic regions often having more than one infection during their lifetime. The risk of DHF rises substantially with second or subsequent infections, further emphasising the need for early diagnosis that enables early treatment and care.

Launch of New High Performance Circulators

Atomising Nozzles Deliver Precise Spray Pattern
The new atomising spray nozzles from Lee Products generate a precise 50° hollow cone spray pattern to ensure controlled atomisation in a very compact package. They are available in both airless and air-assisted styles and will suit critical spray applications in laboratory, medical device, general design applications or wherever exceptionally precise spray patterns are required. The airless atomising nozzles do not require an external air supply and will atomise with pressures as low as 10 psi (on water). They are available in multiple flow ranges and can be installed directly onto a proprietary VHS micro-dispense valve for precise flow control using pulse-width modulation (PWM).
The air-assisted models utilise an external air source to control the atomisation and allow for lower operating pressures (5 psi). The pressure of the liquid and air can be independently controlled to fine-tune the flow rate and nozzle performance to suit the application requirements. In addition to the standard options, Lee Products can supply these atomising nozzles with special mounting configurations and PEEK wetted materials on request.

The new Unistat 905w is the latest addition to the Unistat®
range of high performance circulators from
Huber. With 6kW heating power, cooling powers from 4,5kW @ 0°C and 0,7kW @ -80°C and a temperature range of -90 to 250°C the new 905w brings a tailored cryogenic solution to lower volume reactors. Introduced to the market in 1991, and with a temperature range from -120 to +425°C, the Unistats®
were designed for
demanding temperature control applications where reliability, predictability and tight control are a necessity in a constantly changing reaction mass. Critical process temperatures can be maintained through mixing, ingredient addition, exothermic and endothermic reactions. This level of temperature control can lead to increased yields, lower resource consumption and lower running costs, making the Unistats®
a more
efficient and profitable alternative to other temperature control methods. Designed to give the highest possible flow rates, the new Unistat®
905w
features an efficient variable-speed pump with soft start. This enables the safest and fastest ramp rates resulting in tighter control of process temperature while protecting your reactor and maximising process efficiencies. The pressure of the thermal fluid is closely controlled and monitored by an adaptive controller that brings a new level of precision to thermal control that can be delivered to a wide variety of applications. A hydraulically sealed circulation thermostat, the Unistat®
905w allows fluids
to be used safely above flash points without the fear of ignition and associated greasy residue that comes from oil vapours. In addition, because the fluids are not exposed to the atmosphere whilst being heated and cooled, they do not degrade dramatically extending their lifetime by years.
