Laird Advances DNA Replication Process with New PCR Cycler

Global technology leader Laird (LRD: London) is lowering the barriers-to-entry and increasing service differentiation for both manufacturers and solution providers of medical equipment with the release of a new PCR (Polymerase Chain Reaction) Cycler Evaluation Kit.

 Laird’s new Evaluation Kit enables faster and more reliable results for DNA replication processes. This allows medical equipment manufacturers and solutions providers to offer their customers more reliable and accurate results in less time which allows for shortened drug development times and increased throughput in testing labs.

 For example, when diagnosing hereditary diseases, identifying genetic fingerprints (used in forensic sciences and paternity testing), and detecting or diagnosing infectious diseases, Polymerase Chain Reaction (PCR) is often used to replicate the DNA being tested.  This is an exacting process, often times requiring the rapid heating and cooling of the DNA sample based on a predefined series of temperature steps. Simple temperature controllers can often overshoot set temperature points when ramping at these fast rates.  This can frequently lead to inaccurate test results.

 "The market is evolving toward faster chemistries used in DNA amplification. Too many manufacturers are using simple temperature controllers that are not sophisticated enough to manage fast thermal responses," explains Anders Kottenauer, Senior Vice President of Laird's Engineered Thermal Systems business. He adds, "Use of our new PCR Cycler technology can improve test accuracy and ultimately lead to the detection of new pathogens and treatment solutions.”

 The PCR Cycler Evaluation Kit, identified as model PC-24-TS-58, includes a programmable controller that utilizes an ultrafast thermal feedback loop and two control loops, one for the control side and one for the heat rejection side. These allow the controller to quickly and accurately adjust to the precise temperatures required throughout the process cycle without increasing test time or interfering with the results.

 The controller incorporates alarm features and a port for SD flash memory cards to log temperatures and electric current throughout the duration of DNA amplification.  This verifies that the device is operating effectively and that DNA has been driven to specified temperature set point ranges.

 The evaluation kit includes a thermoelectric assembly, cycling controller and graphical interface.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
