Accurate Pipettes Ensure Reproducible Research

Every researcher relies on accurate and reproducible results to publish research results in renowned journals. Pipette accuracy checks reduce errors, but they are also time-consuming and resource intensive. Choosing a balance that can easily be converted for quick pipette accuracy checks helps to assure the reproducibility of results.

Every researcher needs accurate, reliable and reproducible results to publish their research in renowned magazines. Global standards such as GLP and ISO 8655-6 require pipette testing at defined intervals to ensure their proper functioning. However, in between these periodic checks, researchers typically have little security that their pipettes are functioning properly.

Easy Checks for Repeatability
Pipette accuracy checks reduce errors, but they are also time-consuming and resource intensive. Now, convertible semi-micro balances such as the METTLER TOLEDO NewClassic MS combine standard weighing and pipette accuracy checks in the same easy-to-use laboratory balance for reliable—and reproducible—results.

A Stand Alone Solution
The NewClassic MS105 converts easily from a laboratory balance with 0.01 mg readability into a stand-alone pipette check-station. Firmware guides users through the check process. An evaporation trap is the only external device needed, if the pipetting volume is smaller than 100 μg. The trap keeps humidity levels stable during the check and thus minimizes evaporation for accurate testing.

Automatic Calculation
Distilled water is pipetted onto the balance and converted to a volumetric value. Proprietary embedded MS105 firmware automatically calculates systematic and random pipetting error in absolute and relative values. Results are displayed and can be printed for traceability or for a easy and quick comparison with the manufacturer’s tolerances

Maintaining Academic Accuracy
Convertible laboratory balances such as the NewClassic MS are ideal for use in the life sciences and other research areas requiring absolute surety when publishing results. By performing more frequent pipette checks than the periodic required ISO standard calibrations, researchers gain added security that pipettes are still performing as expected.

Innovative Products for Academic Research
METTLER TOLEDO offers a broad portfolio of high performance laboratory instruments for the academic world. Innovative RAININ pipettes such as the XLS Lite enhance lab performance, and minimize fatigue and injuries. Laboratory balances from the Excellence and NewClassic lines cover all weighing needs, from high performance weighing and One Click™ solutions to basic weighing with smart operation.

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.
