General purpose centrifuge line

Thermo Scientific general purpose centrifuges feature increased capacity and flexibility with rotor innovations including the Thermo Scientific TX-1000 rotor, which employs a 4-liter capacity in a traditional 3-liter footprint. Additionally, the Thermo Scientific MicroClick 30 x 2 rotor offers a 30-place capacity for microtube and nucleic acid spin columns, and is ideal for molecular biology applications. These high-capacity rotors are designed to process more tubes in fewer runs, saving time while reducing energy and wear on the centrifuge. The centrifuge line is designed for a wide range of clinical and life science applications, from cell culture to bioproduction to proteomics, food safety, pharmaceutical, stem cell, microbiology and genomics. The general purpose centrifuge floor models conserve valuable bench space with an almost 25% smaller footprint compared to refrigerated benchtop models and a working height of 79 cm, providing true ergonomic design for removing tubes and exchanging rotors.

EKF Diagnostic’s PlasmaPrep-12 centrifuge

The PlasmaPrep-12 centrifuge for quick blood separations in standard tube sizes is intended for use in both the hospital and clinical laboratory. The PlasmaPrep-12 is designed for STAT serum/plasma separation and is well-suited for coagulation studies as it enables fast blood separation, is easy to use and is controlled by a microprocessor with four pre-programmed spin times. These include the Platelet Poor Plasma mode, providing serum or plasma separations in three minutes, and the Platelet Rich Plasma mode, providing platelet rich plasma in 30 seconds.

LW Scientific’s 2014 USA E8 centrifuge

The new 2014 USA E8 centrifuge is designed, engineered, and assembled at LW Scientific’s ISO-certified, FDA-registered manufacturing facility in Lawrenceville, GA. This new model features improvements such as higher speeds for faster and cleaner separations, quieter operation for peaceful work environments, lower chamber temperatures for cooler test-tube samples, shorter height to fit under any cabinet, and auto-calibrating speed function for precision results. It has an auto-brake to stop the rotor in less than 30 seconds to save time. The E8 family also includes a digital model, with no knobs and precise time and speed programs for CLIA compliance and high accuracy. Laboratorians may choose the fixed-speed model for spinning blood only, or the variable-speed or digital models for spinning blood, urine, fecals, semen, and other fluids at the correct speeds for proper separations and clear results. Three models of USA E8 Porta-Fuge are also available in the E8 family.

Beckman Coulter’s Allegra X-5 air-cooled benchtop centrifuge

The Allegra X-5 air-cooled benchtop centrifuge is designed specifically for clinical sample preparation. Bundled packages, which include swinging bucket rotors and common adapters, enable fast and convenient setup. The small footprint unit offers a capacity for up to 140 blood collection tubes, a maximum speed of 4,700 rpm, and centrifugal force of up to 4,470 x g. Benchtop centrifuges in the Allegra suite are offered for such applications as serum, plasma, and whole blood sample processing; protein precipitation and particulate and cell sedimentation; and in vitro cytotoxicity and receptor binding sample processing.

Thermo Scientific’s Sorvall LYNX Superspeed centrifuge

The Sorvall LYNX superspeed centrifuge represents the latest advancements in centrifugation technology to simplify performance and improve productivity, safety, and reliability. The centrifuge provides 100,000 x g top speed performance and supports sample processing from 50mL conical tubes to 6-liter capacity. Innovations include push-button rotor exchange; Auto-Lock, for fast and secure rotor placement; instant rotor identification; Auto-ID for immediate rotor detection and programming; and lightweight and durable Fiberlite carbon fiber rotors.

New Products

Saveris 2 Wi-Fi data logger system

Testo has introduced the Saveris 2 Wi-Fi data logger system, which precisely measures and records temperature and humidity measurements and transmits them to the testo Cloud via an existing wireless network. The measurement values are then securely stored online, and can be called up at any time using a Smartphone, tablet, or PC.

The system is plug and play, with no software needed to be installed. The only requirements are an Internet connection, wireless LAN, and a normal web browser. In addition to being able to view and evaluate the data from anywhere in the world, an email and/or text message immediately notifies users when alarm thresholds have been exceeded.

Testo Saveris 2 Wi-Fi data loggers have integrated sensors for temperature and humidity measurement or external probes which can be connected to meet a wide variety of applications, including pharmaceutical storage, server rooms, facility management, blood banks, supermarkets, and museums. The data is securely stored on both the Wi-Fi logger and in the testo Cloud.

Biomedical’s  urinalysis transport system

Biomedical Products Corp. offers  color coded  screw caps,  clear 10 ml  plastic tubes with an inside conical bottom within the tube for urine sediment analysis after dip stick chemistries analysis.

These collection and specimen transport tubes are ideal for transport of urine specimen without leakage from off-site clinics to the reference main laboratory for testing. Urine for urinalysis, culture, and special chemistry can be placed into the transport tube containing a preservative which allows specimens to be transported without the need for refrigeration for 24 to 48 hours while maintaining the integrity of the specimen. Tubes are packaged in case of 500 tubes.

Fluid Metering’s valveless OEM pumps

Miniature, stepper-driven valveless OEM pumps from Fluid Metering, Inc. (FMI), are ideal for low and micro-volume fluid control in Medical Diagnostic and Clinical Chemistry Instrumentation.

FMI OEM pumps integrate FMI’s unique patented CeramPump valveless pumping principle with precision stepper control.  The CeramPump utilizes one moving part, a sapphire-hard ceramic piston, to perform all fluid control functions, eliminating valves typically present in low volume metering technologies.

The valveless function is accomplished by the synchronous rotation and reciprocation of the ceramic piston within a precisely mated ceramic liner. The reciprocation action of the piston, similar to a standard piston pump, accomplishes the pumping function.  However, that’s where the similarity ends.  The piston also rotates, alternately aligning a flat at the end with the inlet and outlet ports of the pump.  When the flat is aligned with the inlet port, fluid can be drawn into the pump.  When the flat is aligned with the outlet port, fluid can exit the pump.  Only one port is open at any time and at no point are both ports interconnected. This effectively functions as, and replaces, conventional check valves.

Utilizing sapphire-hard, dimensionally stable components, as well as eliminating check valves, results in a pump that will maintain 0.5 percent precision for millions of cycles without maintenance or recalibration.  The CeramPump, having only one moving part in contact with the fluid, eliminates multiple syringes, valves, and actuators typically present in other low and micro-volume metering systems.
