Designed to work with all sample storage 96-format tube and rack combinations, without use of adapters, the Univo Electric Capper CP480 sets a new benchmark for ease of use, versatility, and speed of operation. Operating as a stand-alone benchtop unit the compact Univo Electric Capper is able to uniformly cap a complete rack of 96 sample storage tubes in only four to nine seconds—less than half the time of competitive systems. The versatile Univo Electric Capper can cap all Micronic plug style caps: capmats, capbands, and capclusters made of TPE, EVA, or other materials on 96-format Micronic tubes and racks. The capper is also compatible with most other brands of tubes and caps. The Univo Electric Capper is extremely easy-to-use. For capping, simply place the rack filled with tubes in the sample holder and place a capmat, capband, or capcluster on the tubes.


The Brooks Plate Auditor is a fast, accurate, and noninvasive tool for identification of precipitate and empty wells in compound and screening plates. The new Plate Auditor is the result of a successful collaboration with the Scripps Research Institute. The new Plate Auditor is designed to evaluate the quality of microplate-based compound samples for precipitation and liquid volume prior to use in compound management and high throughput screening activities. The system rapidly analyzes plates to automatically verify sample integrity thus eliminating the need for extensive manual quality control. The ability of the instrument to provide sample color information makes the Plate Auditor a unique option for monitoring sample quality over time, and identifying wells with artifacts which may interfere with or invalidate screening results.


CloneCatcher Gold DH5G Electrocompent E. coli cells exhibit extremely high electroporation efficiencies that approach the theoretical maximum of 3.4 x 1011 cfu/μg pUC19 DNA. Transferring exogenous DNA into E. coli is a standard laboratory method for cloning genes and constructing cDNA, genomic, and epitope libraries. The limiting factor in many library-screening efforts or multiple fragment ligations is the efficiency by which DNA can be introduced into E. coli. Electroporation is one method to efficiently introduce DNA into E. coli. CloneCatcher Gold cells meet the needs of scientists that are seeking to find rare clones or are building complex or metagenomic libraries. CloneCatcher Gold significantly outperforms all other commercially available Electrocompetent Cells when introducing ligated DNA. When the amount of input DNA is limited, CloneCatcher Gold enhances your likelihood of success. CloneCatcher Gold requires less topoisomerase-loaded vector and therefore can reduce the overall operating costs.


A new 5 μm particle has been added to the Kinetex core-shell product line. As the largest diameter particle in the family, Kinetex 5 μm core-shell columns deliver better performance than 3 μm or 5 μm fully porous offerings, with no increase in backpressure. In fact, the new 5 μm media provides 90% higher average efficiencies compared to the same size fully porous columns and little to no method development is required to achieve improved performance on standard high-performance liquid chromatography (HPLC) systems. Chromatographers can simply substitute these columns into reversed phase HPLC methods that use traditional fully porous columns. Kinetex 5 μm delivers increased resolution and higher efficiencies and extends the scalability and portability of the product line. With the current range of available particle sizes, including 1.3 μm, 1.7 μm, and 2.6 μm, the same method can be easily transferred from UHPLC to HPLC to Preparative LC with Kinetex Core-Shell Technology


A line of thermal test enclosures for the ThermoJet ES precision temperature cycling system is now available. The thermal enclosures provide highly accurate testing and processing of temperature sensitive electronic products. Available in either clamshell or hood configurations, the thermal test enclosures may be used to isolate a device under test (DUT) at a precise temperature insulated from external conditions, thereby providing the optimal conditions for highly accurate testing. Maintaining a uniform stable temperature with real-time thermal measurements on a DUT, the new thermal enclosures deliver unmatched test accuracy and precision. The thermal enclosures allow temperature testing of a variety of device sizes into almost any test setup, enabling characterization, qualification, and fault isolation on components or production level testing. All thermal test enclosures are electrostatic discharge-free and/or electromagnetic interference shielded.
