Measuring Range 5-100 ℃ Fully Automatic Characteristic Viscometer Timing Range 0～999.99s

ST204A Fully Automatic Characteristic Viscometer

The ST204A fully automatic characteristic viscometer is suitable for the second method of the Chinese Pharmacopoeia General Rule 0633, the Ubbelohde capillary viscometer determination method, and the USP<911>viscosity Ubbelohde capillary method design and manufacturing. This method uses the relative method to measure the time required for a certain volume of liquid to flow through a capillary tube under the action of gravity, in order to obtain the fluid's kinematic viscosity.

The ST204A fully automatic characteristic viscosity analyzer has a series of fully automatic functions such as automatic constant temperature, automatic extraction, automatic timing, automatic calculation, automatic printing, automatic cleaning, and automatic drying in automatic mode. When in use, only one injection click is needed to start the experiment.

The Ubbelohde capillary viscometer selects a capillary viscometer with an appropriate inner diameter specification based on the viscosity range of the sample to be tested (Table 2 of the 2025 Chinese Pharmacopoeia).

Technical performance parameters:

● Compliant with standard: General Rule 0633 of the Chinese Pharmacopoeia 2025

● Temperature measurement range: 5-100 ℃ (with refrigeration)

● Temperature control accuracy: 0.1 ℃

● Display mode: Adopting human body sensing touch screen

● Operation process: The entire process of sample temperature control, detection, calculation, viscosity tube cleaning, drying, and report printing is automated

● Viscosity tube fixture: made of all 304 stainless steel material, with high and low temperature resistant graphite sliding bearing device

● Time recording: Automatically determine and record the flow time of the solution and the flow time of the solvent

● Test frequency: The test frequency can be set according to the experimental requirements

● Cleaning frequency: The cleaning frequency can be set according to the test sample and the difficulty of cleaning the sample

● Constant temperature time: The constant temperature time is set differently according to the temperature being tested. For example, if the temperature is generally 25 degrees, the constant temperature time is set to 15 minutes

● Intrinsic viscosity: Automatically calculate the intrinsic viscosity value according to the 2025 Pharmacopoeia General Principles

● Timing range: 0.0s to 999.99s;

● Timing accuracy: 0.01s

● Historical data: The query of historical data can be based on the testing time to retrieve historical records

● Detection method: photoelectric sensor detection

● Result output: It can also be equipped with a USB drive output function to output to the PC for long-term storage

● Data storage: USB data export function

● Software extension: The software can be remotely upgraded according to customer needs in the later stage

● Printer: equipped with a micro printer

● Power consumption of the whole machine: not exceeding 2000W.

● Working power supply: AC220V ± 10%; 50Hz

● Size and weight: 450 * 380 * 550mm 38kg
