Fluorescent conjugates
Affinity-purified antibodies labeled with a series of advanced fluorescent dyes offer intense fluorescence and photostability, properties that allow the detection of low-abundance proteins with sensitivity and specificity. These DyLight fluorescent conjugates combine the sensitivity and reproducibility of the manufacturer’s antibodies and streptavidin with the intensity of the dyes to provide brilliant analysis in fluorescence microscopy, flow cytometry, Western blotting, enzyme-linked immunosorbent assay, and other fluorescence applications. They provide a higher-performance alternative to conventional Cy dyes and fluorescein. The conjugates are offered with DyLight 488, 549, and 649 dyes, which have well-differentiated emission spectra to facilitate sensitive multicolor analysis.

Thermoconductive modules
A line of portable thermoadaptive modules for tube and plate cooling and heating have been designed to keep laboratory samples organized during these procedures. Each CoolSystem ensures that every tube or plate in the ThermalTray remains organized and kept at a precise temperature all day. The tray provides a stable, constant-temperature platform for the various tube and plate modules that can be used; modules never sink into the ice or water bath so samples cannot float, get lost, or become contaminated. Operating with any temperature media, including ice, dry ice, water baths, heat plates, and liquid nitrogen, the modules organize and keep secure dozens of temperature-stabilized samples.

Temperature controller
Designed for the electrophysiological, cellular, and neurological sciences, the TC-144 dual-temperature controller is capable of simultaneously driving two devices within a temperature range from ambient to 65°C. The device is a compact, basic, on-off controller with a slowly ramped switching speed, making it well suited for large mass devices where the temperature changes slowly. The controller can be powered from a wall adapter, as well as from a 12-V battery for sensitive electrophysiology applications.

Spot curing system
The new BlueWave LED visible light, high-intensity spot curing system has no bulbs to change and maintains a constant intensity for thousands of hours. The system generates light using an array of surface-mount light emitting diodes instead of traditional metal halide or mercury bulbs. The visible light energy produced in a relatively narrow wavelength band is centered at 410 nm. The system emits a maximum visible light intensity output of over 2500 mW/cm2 from an 8-mm diameter lightguide, and allows users to adjust intensity output from 0 to 100%.

Tapered tip needles
When dispensing high-viscosity fluids with standard blunt-end tips, extra pressure is necessary to overcome the resistance when entering the straight needle tube. A tapered dispensing needle designed specifically for high viscosity adhesives and silicone is well suited to effectively prevent and reduce the tertiary pressure phenomenon. The needles’ molded, plastic, tapered design diminishes the post-dispensing ooze that can be experienced with blunt-end tips, particularly when using high-viscosity fluid requiring higher pressure to dispense.

MDS42-competent cells
Multiple-Deletion Strain 42 (MDS42) is the only competent cells commercially available with a completely sequenced and analyzed genome. A series of deletions were performed to remove nonessential genetic elements, which has improved the transformation efficiencies and improved protein expression. With 15% of nonessential regions of the genome removed, the MDS42 competent cells contain no insertion sequences elements, phage and prophage elements, recombination regions, and endonuclease A, which may cause problems for modern lab applications.

Brushed dc motor
An addition to an electric motor manufacturer’s highest-performance range of brushed dc motors features an ironless rotor so that the drive operates detent-free and exhibits minimal rotor inertia. The RE 65 motor delivers 250 W and is suitable for applications requiring high efficiency, high power density, and minimal operating noise. Depending on the type of winding, the motor’s cylindrical drive, which measures 65 mm in diameter by 130 mm in length, produces a nominal torque of 0.5 to 0.9 N•m at a nominal speed of 2400 to 3700 rpm. Offering a very high power density, the motor can attain efficiency levels as high as 90%, and its nominal voltages in the 18- to 70-V range make it well suited for battery-powered applications.

Hybrid linear actuator
A size 11 double-stack noncaptive hybrid linear actuator is suited for compact linear motion applications requiring precise positioning and rapid motion, including medical equipment, handheld instruments, and valve controls. The 28000-series actuator has a leadscrew that runs axially through the center of the motor and is restrained from rotating; as the internal threaded rotor rotates, the leadscrew moves axially but does not rotate. This design is appropriate when long linear travel is a requirement and in applications in which the leadscrew is secured at both ends and the motor translates along the screw. Available in a variety of resolutions ranging from 0.000125 to 0.002 in. per step, the actuator delivers thrust up to 30 lb. Standard and custom configurations are available.
