FAQs

Which calibration substance is included in the dropping point accessory box?

The dropping point accessory box contains the following calibration substance:

  • Benzoic acid

What does the dropping point accessory box consist of?

The DP accessory box is included in the standard delivery of the DP70 and DP90. It provides useful accessories for reliable sample preparation:

  • The DP sample preparation tool that enables efficient and clean filling of up to 4 dropping and softening point cups with liquid or solid substances, including a handle to place or remove the tool's plate into an oven or a refrigerator
  • Two tamping rods to press ground solid samples into dropping or softening point cups
  • 2 softening and 2 dropping point cups made of chromium-plated brass
  • 2 stainless steel balls according to ASTM D6090
  • 2 cup lids with vent hole to close the sample-containing cup
  • 6 glass cups for collection of liquefied or softened samples during the respective tests
  • Sample carrier that holds two dropping or softening point cups with glass collectors and cup lids
  • A stand that holds two sample carriers
  • A spatula to transfer the sample into a cup or to remove excessive sample
  • A rod to remove excessive lubricant grease from a dropping point cup according to the procedure specified in ASTM D556
  • Benzoic acid reference substance for calibration of the instrument

When is the use of a steel ball required?

Depending on the substance softening, it may be necessary to promote the flow by applying a ball weight. When performing softening point determination of resins according to METTLER TOLEDO’s cup-and-ball method (ASTM D6090), a steel ball with a diameter of 8.7 mm and a weight of 2.77 g is required to weigh the sample in the cup. The ASTM D6090 standard is based on METTLER TOLEDO instruments and specifies the requirements for automatic softening point determination of resins.

Are there solutions that help to avoid tedious cleaning?

Tedious and time-consuming work in dropping and softening point analysis involves cleaning the components after completion of the analysis. Unhealthy, nonpolar solvents may be required in order to dissolve the sample residues. METTLER TOLEDO provides disposable aluminum sample cups and glass sample collectors that make cleaning unnecessary. The post-treatment process is, therefore, significantly accelerated, and the system is ready for the next measurements within a short time. The dropping point system by METTLER TOLEDO is therefore much more efficient than other competitor systems that require complete cleaning of the sample holder prior to the next analysis.
