Peristaltic Pump for Challenging Liquid Handling

Integra has launched a new version of its popular Dose It peristaltic pump with enhanced functionality, enabling laboratories to undertake even challenging liquid-handling tasks. The new Dose It Customize software mode allows users to create their own personalised liquid-handling protocols. Up to 20 consecutive dispensing and aspirating steps can be defined. A range of settable parameters, such as volume, flow rate and repetitions, can be assigned to each step.

In addition, the flow rate can be set to ramp up or down to the target speed, avoiding foaming, splashing or unwanted turbulences during dispensing. Applications that have benefited from the new Dose It Customize mode include gentle filling of density gradient tubes by slowly increasing the flow rate, coating Petri dishes by adding and removing coating solution, and preparing serial dilutions by having an air gap between sample and the diluent.

Simple to set-up and implement, the scope for optimised liquid-handling protocols using the Dose It is said to be almost limitless. Dose It is an intuitive programmable peristaltic pump that simplifies the dispensing of cell-culture media, buffers and other solutions for volumes ranging from 0.1 to 2,500ml. Dose It features a very small footprint and weighs 3.5kg, making it suitable for bench-top or in-hood dispensing applications. Programming the Dose It is fast and easy through a multilingual user interface (English, Spanish, German, French and Italian).

The instrument's pump head accommodates the use of different tubing diameters (1-8mm), allowing a range of volumes to be dispensed with optimal speed and precision. A built-in print capability supports the capture of program details for record keeping and quality control. Many accessories are available to support a variety of dispensing applications.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
