ST211A Manual Constant Temperature Cone Penetrometer Resolution 0.01mm Ointment

Product Specification

ST211A Manual constant temperature cone penetrometer

The ST211A manual constant temperature cone penetration tester is designed and manufactured according to the technical requirements and relevant regulations of the 2025 Pharmacopoeia 0983 cone penetration measurement method. It is mainly suitable for semi-solid substances such as ointments, eye ointments, and commonly used matrix materials (such as Vaseline, lanolin, beeswax) to control their properties such as softness, hardness, and viscosity, and avoid affecting the coating ductility of drugs.

Main technical features:

● Using a digital display to show the cone penetration value, it is intuitive and eye-catching.

● It has the functions of coarse and fine adjustment of the lifting frame, easy adjustment, and accurate needle alignment.

● Equipped with a heating and cooling constant temperature bath, automatic temperature control of the water bath, and high cost-effectiveness of the instrument.

Main technical parameters and indicators:

● Measurement range: 0-700 cone penetration (digital display shows 0-70mm)

● Cone entry timing control device: The time can be set arbitrarily according to one's own needs, with a time error of less than ± 0.1 seconds

● Resolution: 0.01mm

● Needle insertion accuracy: ± 1 cone penetration degree

● Temperature measurement range: 10-50 degrees (equipped with semiconductor cold cycle device, capable of heating or cooling)

● Temperature control accuracy: 25 ± 0.1 ℃

● Temperature control method: high-precision digital temperature controller, capable of maintaining a constant temperature up to the standard requirement of 25 degrees

● Standard cone: 102.5 ± 0.05g, in compliance with the 2025 Pharmacopoeia

● Lifting bracket: dual lifting adjustment mechanism for coarse and fine adjustment, making it easy for the needle tip to align with the sample plane

● Other: Equipped with a cold light source for easy use and operation.

● Standard cone:

Cone 1: The mass of cone I is 102.5g ± 0.05g, the mass of the matching cone rod is 47.5g ± 0.05g;

Cone 2: The mass of cone II is 22.5g ± 0.025g, the mass of the matching cone rod is 15g ± 0.025g (optional)

Cone No. 3: The total mass of cone No. III and cone rod is 9.38g ± 0.025g (optional)
