Drying under control

Retsch of Haan, Germany, has introduced its Rapid Dryer TG 200, which produces a constant flow of warm air to keep particles agitated and separate.  

The result is a rapid, gentle and uniform drying process without localised overheating or agglomerations, providing a loose, thoroughly mixed product.  

Benefits include a maximum drying temperature of 150°C, digital controls for temperature, time and air flow, and interval mode for improved mixture of fluidised bed. 

Processing times in the TG 200 range from five to 20 minutes. 

Typical samples include coal, fertilisers, plants, plastics, soils, and waste. The Rapid Dryer can also be used to dry quickly test sieves or other laboratory items. 

Clean, dry nitrogen

Domnick Hunter of Birtley, UK, has extended its range of liquid chromatography/mass spectrometry nitrogen generators with the launch of four new models: the LC/MS 15, LC/MS 20, LC/MS 30, and LC/MS 40. These new models have been designed to meet the gas flow, purity and pressure requirements of the latest generation of LC/MS instruments.  

The generators can supply nitrogen to single or multiple instruments and can drastically reduce ongoing laboratory gas costs. Using fully regenerative pressure swing adsorption technology, the generators provide a continuous stream of clean, dry nitrogen without the need for secondary purification. They are fully compatible with all known atmospheric pressure chemical ionisation and electrospray ionisation interfaces.  

Models featuring integral oil-free compressors give increased security of supply, and remove the reliance on external air supplies. Dual compressors reduce the duty cycle. 

Domnick Hunter has recently appointed Kinesis as a primary distributor for its range of laboratory gas generators in the UK. 

Simpler rotary evaporation

The new modular R-210 and R-215 Rotavapors from Büchi Labortechnik of Flawil, Switzerland, offer a range of glass assemblies, vacuum controllers and a choice of vapour temperature and rotation display.  

The Rotavapor bath obtains its mains power in a similar way to a cordless kettle, allowing easy removal and cleaning. An infrared sensor transmits the bath temperature to the Rotavapor. The vapour duct establishes an end-to-end connection between the evaporation flask and the condenser, thus preventing possible cross-contamination, and the Combi-clip makes it easier to remove and change the flask and vapour duct assembly. 

Integrating pipetting data

Tecan from Männedorf, Switzerland, has launched four new software packages: Freedom EVOware Sample Tracking, Freedom EVOware 1.2, Magellan 6.0 and i-control. Freedom EVOware Sample Tracking software integrates data from Freedom EVOware 1.2 and Magellan 6.0 for easy combination of plate readers and pipetting platforms. 

The sample tracking software can register scanned labware, and integrate and process all pipetting, methodological and plate reader data. It also stores the results before generating and exporting reports and is compatible with an extensive range of Tecan products. 

i-control software controls the Infinite series of readers and is similar to Freedom EVOware 1.2. The two software packages integrate seamlessly with each other, with i-control taking over from Freedom EVOware once the microplate is transferred to the Infinite reader. 

Fluorescence monitored

An advanced system to apply time-resolved fluorescence spectroscopy on the micrometre scale has been developed by the Spex Fluorescence division of Horiba Jobin Yvon of Stanmore, UK.  

Time Correlated Single Photon Counting (TCSPC) components fit directly to microscopes to give fluorescence lifetime measurements.  

Light sources are interchangeable 'plug and play' pulsed laser diodes or light emitting diodes (LEDs), including the first deep ultraviolet LED light sources (280 nm and 340 nm). Ultraviolet LED 280 can measure fluorescence lifetimes of proteins, such as tryptophan, directly from tissue samples. 

The system can be used to measure lifetimes from 100ps to 100 µs with TCSPC and phosphorescence lifetimes of over 10 µs.   

This system can  be used for cellular and tissue analysis by monitoring fluorescence from conjugated fluorescence markers and quantum dots, and auto fluorescence from proteins, DNA and antibodies. 

The magic touch in your lab

Metrohm has introduced Titrando Touch Control as an ergonomic control unit for titrators. It can be held in the hand, placed on the lab bench or attached to the wall. 

The Titrando supports all potentiometric titration modes, including dynamic equivalence point titration, monotonic equivalence point titration and SET (titration to one or two preset endpoints). 

The Titrando is fitted with a measuring interface that can measure pH, potential, temperature and the concentration with ion-selective electrodes.

Basic laboratory operations such as pipetting, transferring, dosing, dispensing and diluting can be controlled using the liquid handling functions of a dosing interface, Dosino. 

The Titrando can control sample changers, sample preparation steps and unattended overnight operation.
