The Sarmix MR 1 is a versatile and economic rotating mixer. It has three rotisserie configurations, two rotisserie positions, and can be placed in various positions to produce a wide range of motions. When the rotisserie is mounted in the vertical position, a gentle rolling motion is produced. For more vigorous mixing, the rotisserie can be placed horizontally. The same rotisserie position is used to create a tumbling movement by tilting the unit to rest on either end. Any of the three rotisseries can be used as a rocking platform.


The new Dionex ICS-5000+ Reagent-Free HPIC system is designed to elevate ion chromatography separation capabilities to new levels of resolution, speed, and flexibility. The new Dionex ICS-5000+ Reagent-Free HPIC system is designed to operate at continuous pressures up to 5,000 psi at analytical flow rates and extend the benefits of high-pressure ion chromatography to standard bore and microbore as well as capillary format separations. High backpressure tolerance is intended to let users increase flow rates to maximize throughput while still providing the advantages of electrolytic eluent generation and suppression. The Dionex ICS 5000+ HPIC system features a proprietary all-PEEK polymer flow path for metal-free inertness with the strength to operate continuously at 5,000 psi. The Dionex ICS-5000+ HPIC system can use the new high-efficiency 4 μm-particle-size IC columns at high pressures, which may enable users to discover peaks they have been missing.


The groundbreaking BWB XP is the only five-channel flame photometer in the world offering simultaneous detection and display of all five elements. The incorporation of high-quality build and unparalleled performance with state-of-the-art technology provides improved accuracy and stability while significantly reducing analysis time. BWB flame photometers have been designed to combat the challenge traditionally faced in photometry such as maintaining flame intensity, consistency in liquid to flame flow rate, and pressure to fuel gas flow rate, all of which affect the photometers ability to determine the concentration of metal ions. Benefits include analysis in parts per million and a clear, intuitive LCD display—which eliminates the need for specialized training, saving time and money. In addition to logical simplicity, the BWB flame photometers include everything required to use the product straight from the box—just add gas. The built-in air compressor greatly reduces noise and laboratory footprint while increasing instrument stability, accuracy, and reproducibility.


The Hyb-Ice Thermal Profiling System is an affordable and flexible alternative to a standard thermal cycler for performing everyday temperature profiles. The system consists of a programmable heating/cooling base and removable block that heat and cool samples from 4°to 99° The system accommodates a variety of quick-change blocks to fit nearly any tube or plate. The Hyb-Ice System provides excellent temperature regulation, uniformity, and ramp rates and performs polymerase chain reaction in either standard- or large-volume tubes. A non-contact heated lid controls condensation. Programs can be stored or run via an onboard USB drive.


The PowderSafe Type B Enclosures usher in a new era of powder weighing and containment technology. PowderSafe Type B enclosures provide a controlled negative pressure HEPA-filtered environment for professionals to work with and weigh powders. PowderSafe Type B is fabricated with polypropylene, which is a chemically resistant, high-mass polymer. The innate chemical resistance of polypropylene allows users to easily clean the enclosure without the worry of degradation, while the high-mass construction alleviates the threat of vibration and balance disturbance during weighing. Exclusive to PowderSafe enclosures, HepaSafe technology allows the operator to safely and easily change both the prefilter and the primary HEPA filter while the enclosure remains under negative pressure. Furthermore, FlowSmooth technology provides even, horizontal air distribution throughout the enclosure, preventing turbulence. This laminar horizontal air movement is also key to operator protection from hazardous chemical and compounds being manipulated within the enclosure.
