New Industrial Rotary Evaporator After 10 successful years in the market, Buchi’s 20 litre Rotavapor®
R-220 is ready for an upgrade. Buchi has refined its industrial Rotavapor implementing
R-220 SE focuses on safety and ease-of-use. The concept behind all Buchi equipment stems from the idea that with easy handling, safer operation is achieved. The patented EasyClamp executes fast and safe installations while securing glass joints.
new accessories and technologies with its new Rotavapor R-220 SE (Second Edition). The new Rotavapor®
The simplistic intuitive design of the control panel provides essential information including bath, vapor and cooling temperatures without complicated menu navigation. Additional safety precautions can be taken by attaching an optional safety enclosure, which does not restrict access to the glassware.
Technological advances come in the form of the new level sensor and USB module. Minimise the time spent supervising the evaporation process by automating the endpoint with the receiving flask level sensor. The USB module is capable of recording data and interfacing with peripheral equipment to provide a state-of-the-art large-scale evaporation solution. Intelligent, easy-to-handle, and above all, safe operation makes the new R-220 SE the right decision for your large-scale evaporation needs.

The World’s First Multiple Wavelength Refractometer
Video Demonstrates Evaporator Versatility & Ease of Use
Genevac has announced a new online video demonstrating the ease of use and market-leading operational versatility offered by its Rocket™ Evaporator.
Presented as a Flash media presentation
(
www.genevac.com/movie/rocket/) the new video includes an informative introduction to the revolutionary evaporation technology used by the Rocket. Following this the viewer is seamlessly guided through the system operation – from the wide range of compatible sample holders for drying and concentration, loading samples, ease of operation, stored method programming through to proprietary Genevac innovations that ensure sample integrity.
Analytik Ltd introduce the DSR-L from Schmidt + Haensch as the world’s first automatic refractometer to measure refractive index at multiple wavelengths. The use of discrete LEDs makes it possible to implement any combination of customer-specified wavelengths, allowing quasi-spectral measurements in almost real time.
extremely valuable in both R&D as well as quality control. It is ideal for measuring the refractive index dispersion of proteins, viscous materials, lenses, glass, thin film, and polymers and can be used to test product purity, characterise optical materials, identify counterfeits, and analyse quantities of dissolved solids like sugar, glycol and fats.
By precisely measuring samples at seven separate wavelengths (400nm, 435.8nm, 486.1nm, 546.1nm, 589.3nm, 656.3nm, & 706.9nm), the DSR-L gives unique fingerprint-like data. There are many solutions that are chemically different but display comparable refractive index values at the traditional 589.3nm wavelength, however because the DSR-L can measure RI at multiple wavelengths, key differences can be obtained from otherwise similar samples. The electronic Peltier device controls temperatures from +18 to +30°C and eliminates the need for an external water bath or thermostat. With accuracy of ±0.01°C, a temperature is easily set and the automatic refractometer quickly heats or cools to the target temperature. The DSR-L also features a long-lasting LED light source (100,000 hours), linear high-resolution CCD sensor, menu-driven backlit LCD displays, 4 user profiles, password protection, printer and data ports, and optional USB ports.
The included software package and RS-232C cable make it easy to connect the DSR-L to computers for collection of measurement data or for remote operation with full command of all functions. As new software versions are released, the instrument can also receive flash updates.
The DSR-L is suitable for ASTM D 1747 Standard Test Method for Refractive Index of Viscous Materials and ASTM D 1218 Standard Test Method for Refractive Index and Refractive Dispersion of Hydrocarbon Liquids.

Benefiting from a patented low temperature, low pressure steam heating technology - the Rocket Evaporator is able to uniquely achieve the dual goals of very fast evaporation with very precise temperature control thereby accelerating the safe concentration or drying of samples. Developed in response to user requests for an evaporator that could quickly process larger volumes of solvent in parallel and without supervision, the Rocket Evaporator is designed to dry or concentrate six flasks, each containing up to 450ml of solvent. For scientists looking to concentrate extracted samples prior to analysis - the new Puck sampling accessory extends the sampling versatility of a Rocket Evaporator to simultaneously accommodate up to eighteen 60ml Accelerated Solvent Extractor (ASE®
) tubes. Circle no. 369
Efficient Pre-Concentration of Protein Solutions
For laboratories looking to pre- concentrate protein solutions prior to separation (size exclusion chromatography, electrophoresis) or analysis (x-ray crystallography) the miVac sample concentrator from Genevac provides a highly efficient, cost effective alternative to traditional membrane centrifugation techniques.
Using membrane centrifugation valuable sample is often lost due
to protein binding to the membrane. By comparison using a miVac sample concentrator ensures complete sample recovery even when taking proteins to very high concentrations. For protein laboratories that handle large numbers of protein samples - the miVac also offers the benefit of greatly reduced spending on consumables.
The miVac range has been designed to meet the requirements for speedy, yet careful biological sample concentration. Each miVac sample concentrator is designed to provide very high performance, precise temperature control and ease of use – all within a small benchtop footprint. miVac sample concentrators are capable of removing water and organic solvents from a variety of sample formats including tubes, microplates, and vials. Built-in stored methods for drying aqueous and alcohol-based samples improve performance and optimise concentration time.
