Centrifuge The medium capacity Allegra X-30 Series Benchtop Centrifuge from Beckman Coulter, Inc. is a versatile instrument for general research use and clinical sample preparation. The 18-inch-wide instrument is available individually or packaged with the appropriate rotors and lab ware to provide high-level performance in a range of applications. Additionally, two new rotors are available in conjunction with the Allegra X-30 instruments: the SX4400, a 1.6-litre swinging-bucket rotor and the S6096 microplate rotor that accommodates 3 x 2 microplates or 2 x 1 deep-well plates. With its newest swinging-bucket rotor and 15 and 50 mL conical tube adapters as well as blood sample processing and microplate application packages provide everything needed. Its swinging-bucket rotor’s maximum speed is 4,700 rpm, with rcf of 4,255 x g. In total, the Allegra X-30 accepts 13 different rotors and a range of lab ware to accommodate a variety of samples and run conditions. A refrigerated version of the centrifuge, the X-30R, can be cooled from room temperature down to 4ºC in less than ten minutes.

Chemistry Systems Syrris offers the Asia range of flow chemistry systems for performing a wide variety of chemical reactions. The portfolio includes the Asia 110 system is ideal for beginners in solution phase flow chemistry. It includes a pump, a chip climate controller, a glass microreactor and a pressure controller. The Asia pump is extremely chemically resistant and designed specifically for flow chemistry. It has two continuous pumps for delivering smooth flow from 1µL/min to 10mL/min. The pump has an integrated pressure sensor which allows it to automatically stop in the case of a blockages or leak. The Asia chip climate controller enables the microreactors to be heated from -15 to +150ºC without the need for a circulator or a cold water supply. The entire system can be upgraded to include automated collection, use of solid phase reagents, temperatures up to 250ºC, kg synthesis, analysis integration, flow liquidliquid extraction and full software control.

Injector VICI Valco’s introduces its new Cheminert C52 Series Injector. Using its Cheminert HPLC injector design and the 24 volt motor from our popular microelectric actuators, the C52 needs only to be connected to the instrument’s power supply. Control is simplified to require a single contact closure; the injector’s position is determined by whether the closure is held high or low. There’s even an easy way for the instrument to confirm the valve’s position by sensing the output from a built-in sensor. All these features are built into a compact and lightweight package, available in 4, 6, 8, and 10 port configurations, stainless or PEEK.

Thermometer Control Company’s new Traceable® Infrared Dual Lasers Thermometer with Type-K Probe is simple; turn on, point at sample, and take a reading in less than a second. Dual lasers indicate the outer diameter of the surface area being measured and the white LED light illuminates the surface. Field of view is 12:1 (for example, at a distance of 24 inches the reading spot size is two inches). Unit reads both fahrenheit and celsius of any surface for solids, semisolids, and liquids. Non-invasive, notouch, measurements are ideal for food, life sciences, pharmaceuticals, petroleum products, clean rooms, electronics, and field use. Temperature range is –76 to 1022°F and –60 to 550°C. Resolution is 0.1°. Accuracy is ±2% or 2°C + 2%. For measurement of different types of material, adjustable emissivity may be set from 0.1 to 1.00 in increments of 0.01. Range using Type-K thermocouple jack is –83 to 2552°F and –64 to 1400°C.
