The new Findenser is an innovative and unique air condenser which replaces the need for water-cooled condensers in over 95% of all common chemistry applications. Findenser comprises a glass condenser and an external finned aluminium jacket, between which a small amount of water is permanently sealed. The design of the glass inner and finned jacket mean Findenser has a much greater surface area and heat transfer capacity than a standard air condenser. The result is a 'superair condenser,' that tests have shown performs as well as a traditional water condenser in all popular chemistry applications. Findenser requires no running water to operate, thus eliminating the need to purchase and dispose of water. Findenser can be used in vessels up to 2 L with up to 1 L of solvent. It comes as standard with a B24 ground glass cone and fits all standard tapered glass sockets.


Designed to maximize benchspace, LS-Series/LM-Series/MM-Series Chillers provide up to 1,290 watts of cooling at 20° making them ideal for use with rotary evaporators, jacketed incubators, small reaction vessels, spectrophotometers, chromatography columns, condensers, and other devices that require robust heat removal. Three different models of compact chillers are available: The LS-Series, which has a working temperature range of -20°to +40°and provides 475 watts of cooling at -10° the LM-Series, with a working temperature range of -10° +30°and a 230 watt cooling capacity at -10° and the MM-Series, which has a working temperature range of -5°to +50°and provides 129 watts of cooling at -5° All three models control temperature with ±°stability and are equipped with a low-flow–rate alarm, user-adjustable high- and low-temperature alarms, a top-mounted fill port with built-in fluid filter, lighted fluid level indicator, and washable rigid-frame air filter.


A new range of Aptamer Protein Precipitation Kits bind with unmatched high specificity and affinity to target molecules. The new Aptoprecipitation (AP)/Co-Aptoprecipitation (Co-AP) Kits are aptamer-based protein precipitation kits designed to provide easy, quick, and consistent protein precipitation. The new kits offer a range of unique characteristics and provide significant advantages over alternative methods. Based upon a proprietary oligonucleotide, aptamer kits will not contribute to protein/peptide background that can interfere with subsequent mass analysis. Supplied as a complete kit in which aptamer is covalently conjugated to magnetic beads, you can perform successful pull-down experiments with ease, without the traditional troublesome conjugation step. Unlike antibody-based protein precipitation methods, aptamer is highly specific recognizing just the native form of target proteins, not the denatured form. The mild elution conditions used with Aptamer kits enable isolation of intact proteins and protein complexes.


An exciting new generation of Temperature Control and Mixing Instruments is now set to impress with excellent mixing results, outstanding temperature management, and the ergonomics and simplicity essential for routine use in a busy laboratory. The excellent mixing results of the new Eppendorf ThermoMixer C, F1.5 and FP (two-in one instruments for combined mixing and incubating) are due to the unique 2DMix-Control technology which ensures fast and efficient mixing in just seconds and now offers reliable mixing solutions in 96- and 384-well plates. Controlled circular movements achieve thorough mixing of liquids in even the smallest volumes, while the anti-spill technology prevents lid wetting and cross-contamination. For dry incubation, the new Eppendorf ThermoMixer C and ThermoStat C are operated together with Eppendorf SmartBlocks which are easily exchangeable in just seconds, thanks to the unique Eppendorf QuickRelease technology. These individually sensor-controlled SmartBlocks are the best solution for maintaining accurate, uniform temperatures.


An extensive range of reagent reservoirs are available for 96-well and 384-well multichannel pipetting systems. Adopting a standard SBS/SLAS footprint—the extended range of reagent reservoirs (100 mL and 300 mL) are fully compatible with all liquid handling systems including Integra's VIAFLO 96 and VIAFLO 384 Handheld Multichannel Electronic Pipettes. Individual pyramidal indentations (96 or 384) in each reagent reservoir allow maximum liquid recovery when using the VIAFLO 96 and VIAFLO 384 electronic pipettes as well as other platforms. VIAFLO multichannel reagent reservoirs are both economically and environmentally friendly because users can reuse the reservoir base and dispose of the reservoir inserts. These reagent reservoirs are also designed to nest within one another without sticking and come in compact, space-saving packages.
