We support and service your measurement equipment through its entire life-cycle, from installation to preventive maintenance and calibration to equipment repair.
Please choose your equipment type:
Certified melting point reference standards are substances that enable accurate temperature calibration and adjustment of melting point and dropping point instruments. Each high-purity METTLER TOLEDO reference substance comes with certified temperature values that are traceable to primary standards. Certified reference substances are provided in the range of 40 – 360 °C and are available as standard or as USP melting point reference standards.
With our simple, built-in calibration routines, you can adjust your instrument quickly. Perform a calibration with up to three substances and the instrument automatically calculates the slope and offset values for you.
Each METTLER TOLEDO high-purity reference substance comes with certified temperature values that are traceable to primary standards (LGC, London).
Certified reference substances are provided in the range of 40 – 360 °C to cover the full temperature range for reliable melting, dropping and softening point measurements.
The melting point accessory box contains the following melting point reference substances:
The USP melting point accessory box contains the following melting point reference substances:
The MP VPac™ contains the following melting point reference substances, each in 50 sealed standard METTLER TOLEDO melting point capillaries.
METTLER TOLEDO reference substances such as benzophenone, vanillin, benzoic acid and potassium nitrate provide certified temperature values that can be used for temperature calibration of the DP70 and DP90 furnaces. Caffeine and saccharine cannot be used as they do not drop properly.
USP specifies that the measured melting range must
a) Lie within the specified minimum and maximum temperatures (e.g. 81–83 °C for vanillin), and
b) Must not be broader than the specified admissible values (e.g. 1.5 °C for vanillin).
So, the permitted measured melting range for vanillin could be 81.0–82.5, 81.3–82.8 °C etc.
