Debubbler Series

The Systec Debubbler Series for low-pressure diagnostic and life science instruments improves on passive bubble-trap technology with active bubble removal and transfer-line degassing. Three configurations — active debubbler, degasser/debubbler, or transfer-line degasser — offer the choice of removing bubbles with or without also removing dissolved system gases. Highly efficient online active debubbling helps equipment manufacturers improve dispensing precision, reduce sample loss and reagent usage, and improve analytical accuracy in high throughput applications. The new series features an innovative semipermeable degassing membrane to remove gases from dispensed liquids.

Gel Documentation System

The next generation DigiGenius budget gel documentation system features a high-resolution, computer-controlled camera, allowing molecular biologists to easily view images in real time on any computer. The 10-megapixel camera can separate even the closest band images. The camera can be linked via an interface to a computer in order to automate the camera's setup and images can be captured on either a flash card or computer. Users can choose to add compatible components to the basic system such as an ultraviolet transilluminator or white or blue conversion screens. It comes with a safety hood upgradeable to a full minidarkroom.

Sulfur-Compound Measurement

A sensitive new analytical system enables routine measurement of thiols, thioesters, disulfides, and other sulfur-containing compounds. Sulfur-containing compounds are critical to a variety of biologically and clinically important processes, from oxidative metabolism, to cardiovascular and neurodegenerative-disease mechanisms, to signal transduction, but measuring them has been difficult. The new system incorporates a specially developed electrochemical cell with a unique boron-doped diamond (BDD) working electrode coupled with the Coulochem III ECD system. The electrode provides excellent sensitivity and durability, while eliminating the problems of fouling, high background, and mobile phase oxidation associated with earlier electrochemical detection (ECD) systems.

Precision Optical Filters for Fluorescence Microscopy is a new catalog that includes 15 new high-performance sets for fluorescent proteins and 10 new sets for fluorescence resonance energy transfer. These new products complement an extensive selection of dye-specific filter sets for all single-label and multilabel microscopy applications, including quantum dots, multiplex fluorescence in situ hybridization, ratio imaging, confocal, and multiphoton. Other resources include a fluorophore reference table, light source and detector spectral data, an explanation of filter nomenclature, guidelines for choosing the optimal filter sets, and a list of components organized by wavelength.

Distillation System

The Lab-Crest Midi-Dist Distillation System saves space and time in laboratory testing and analysis requiring distillation. Designed to allow replacement of costly macro distillation techniques, these compact units allow multiple samples to be prepared for analysis quickly and easily. The heater, holder, manifolds, tubing, couplings, and controls are integrated and designed to simplify setup and use. It is comprised of 10 complete borosilicate glass units and a 10-position aluminum heat block and apparatus holder, coated with Teflon for corrosion resistance. Glassware, heater, water, and vacuum manifolds, controls, and connections are integrated into a single compact system. The system can handle up to 10 50-ml liquid or sludge samples.

Multiparameter System

Version 2.0 of the LiQC multiparameter system is for simultaneous determination of density, refractive index, pH/conductivity, and color. The instrument combines single measurements into one automated process. A sample vial is filled, placed on an automatic sample changer, and assigned a barcode label. The LiQC automatically completes every subsequent step: choosing the appropriate method, pumping the sample into the various flow-through cells, and performing all measurements. The instrument evaluates results statistically, compares them to specifications, and transfers them to laboratory information systems. The LiQC thoroughly cleans and dries the measuring cells before moving on to the next sample.
