Mettler-Toledo MCP1-S Pipette Calibration Balances: Calibration Spotlight

The Mettler-Toledo MCP1-S represents top-of-the-line pipette calibration equipment, with capabilities for single and multi-channel pipettes. PTS pairs our system with the Calibry pipette calibration software, fully CFR part 11 and ISO 8665 compliant. This combination ensures accurate, efficient, and precise calibration of pipettes whether in our lab or on a customer site.

The MCP1-S improves both accuracy and time-to-completion for twelve-channel pipette calibrations.

Precision Hardware: MCP1-S

The MCP1-S features the ability to calibrate all multi-channel pipettes with a dispensed volume greater than 10 μl.  This system greatly reduces the calibration time of a multi-channel pipette. Using the MCP1-S allows all twelve (12) channels to be checked in a single step. Additionally, the system provides quick validation of individual channels. ISO 8655 specifies that up to three hundred and sixty (360!) measurements must be taken using a conventional balance: the MCP1-S needs only thirty (30).  When compared to a conventional analytical balance, this fully automatic process improves calibration ergonomics and reduces time requirements by up to ninety (90) percent.  This results in improved calibration productivity and reliability.

Swapping the 12-channel transport carriage with the glass evaporation trap places the MCP1-S in single-channel pipette calibration mode.  The built-in moisture trap around the weighing vessel ensures evaporation and wind currents do not affect even the smallest volumes. Environmental readings recorded prior to calibration, coupled with a Z factor, ensure accurate measurements unaffected by environmental factors. 

The MCP1-S features a controlled chamber for single channel pipette calibration.

Precision Software: Calibry

The Calibry software optimizes pipette calibration according to ISO 8655. Designed with these procedures in mind, the software optimizes data management and guarantees traceability.  Additionally, the accompanying database incorporates manufacturer specifications for each pipette type.  When the user selects a pipette its specifications immediately show, saving valuable time. Calibry automatically adds pipettes to the calibration task list as the recalibration date approaches. Further, calibration results can be viewed at any time during the procedure.  Values outside tolerance limits show clearly in red, allowing technicians to take immediate corrective measures.

Coupled with the Calibry software, the MCP1-S offers unrivaled accuracy and performance when calibrating single- or multi-channel pipettes in our environmentally controlled laboratory.

Precision Partners: PTS

PTS goes to great lengths to ensure all pipette calibrations are accurate and precise.  This includes the design and maintenance of our temperature-controlled PDCL (Pipette/Dimensional Calibration Laboratory). Network-enabled equipment controls and monitors this lab, ensuring ideal conditions within two degrees and three percent humidity. When our partners prefer onsite service, we utilize mobile monitoring devices to ensure complete compliance with required conditions, bringing the precise calibration techniques of our in-house lab to your facilities.

Calibration Spotlight: Hart Scientific 1590 Super-Thermometer II

What Is a Super-Thermometer?

Metrology laboratories around the world rely on super-thermometers for their reliably accurate, easy-to-take measurements.  For instance, the Hart Scientific 1590 Super-Thermometer II reads accurately to 0.00025°C or 1 ppm. This high degree of accuracy makes super-thermometers perfect for calibration of SPRTs (Standard Platinum Resistance Thermometers). Further, they are the best lab instruments to take advantage of SPRT accuracy. They read temperature directly, automate data collection, and calculate constants for ITS-90. Additionally, the large LCD screen of the 1590 Super-Thermometer II features a live graph which records temperature trends during calibration.  This allows PTS technicians to see when the temperature has stabilized enough to ensure an accurate reading.

How Does PTS Use the Super-Thermometer II?

The typical benchtop thermometer has an error level twenty to forty times larger than the Super-Thermometer II. However, the resolution of the 1590 with a 25-ohm SPRT is 0.000125°C. Because of this,  the 1590 Super-thermometer II can easily calibrate Platinum Resistance Thermometers (PRTs), Resistance Temperature Devices (RTDs), thermistors, thermocouples, and related measurement devices. As a key provider in the scientific services calibration industry, PTS services all manner of temperature devices. As an ISO:17025 accredited organization, we meticulously catalog uncertainty data for our 1590. Customers may request this data as needed.

SPRTs interpolate temperature according to the International Temperature Scale of 1990 (ITS-90). In use, the AM1960 covers the range from -200 °C to 670 °C.

We paired our 1590 Super-Thermometer II with a quartz-sheathed SPRT Accumac AM1960. This allows accurate measurements up to 600°C.  This instrument gives PTS the ability to calibrate all temperature devices in-house. Because of this, we have more time to devote to serving our customers. This ensures our turn around time is quick and efficient to minimize the time you are without your instrument. You won’t wait six weeks (or longer!) to receive your PRT or temperature device back from calibration. You can rest assured knowing your temperature device will be calibrated to its greatest degree of accuracy from PTS.
