Tap Density Tester

Description：

The Tap Density Tester is advance microcontroller based with user friendly software in dialog mode. The Alpha-Numeric splash proof keyboard allows entries such as sample name, sample number or ID number for data authentication. The report printout complies with GLP requirements and a built-in Real Time Clock provides date, time display, and authenticity of the printout.

Standards：

ISO 3953

ASTM B527

GBT5162-2021. GB5162-2021.

Specifications:

Features：

Designed to meet current USP and ASTM Specifications fortap density testing.

The unique simultaneous tapping and rotating motion assures that the material is evenly packed.

Calculates test results – Tapped Density, CompressibilityIndex, Hausner Ratio, and Bulk Density.

Two cylinder holders will hold 100 mL and 250 mL cylinders.

Balance interface for sample weight transfer.

Test Method：

This test measures increased bulk density attained after mechanically tapping a graduated measuring cylinder or vessel containing a powder sample. After observing the initial powder volume or weight, the measuring cylinder or vessel is mechanically tapped, and the volume or weight readings are taken until little further volume or weight change is observed.

FAQs:

Q: How do you operate the Tap Density Tester?

A: To operate the Tap Density Tester, place the powder sample into the designated chamber, set the required number of taps, and switch on the device. The tester will automatically perform tapping cycles to compact the powder, after which you can measure the resulting density.

Q: What materials is the Tap Density Tester made from?

A: This tester is constructed primarily from durable plastic, which ensures longevity and resistance to chemical corrosion, making it ideal for laboratory and industrial use.

Q: When should I use the Tap Density Tester in my laboratory process?

A: Use the Tap Density Tester during quality control or material research phases whenever precise measurement of powder compaction or bulk density is required, especially for optimizing formulations or ensuring product consistency.

Q: Where is the Tap Density Tester manufactured and available for export?

A: The Tap Density Tester is manufactured in China and is available for domestic supply as well as export to international markets.

Q: What is the process for measuring tap density using this tester?

A: The process involves placing your powder sample in the tester, setting tap parameters, executing tapping cycles to compact the material, and then measuring the samples final volume and mass to calculate tap density.

Q: What benefits does the Tap Density Tester offer to laboratories and manufacturers?

A: The tester offers accurate and consistent tap density measurements, helps regulate material properties, contributes to meeting industry standards, and supports efficient quality control in manufacturing and research environments.

Q: How does the Tap Density Test Apparatus ensure accurate results?

A: The Tap Density Test Apparatus is equipped with a 1 stroke/min accuracy, a digital presettable counter, and an automatic reset feature. These elements provide consistent and reliable tap density measurements, conforming to USP, ASTM, and IP standards.

Q: What are the benefits of the programmable timer and automatic reset functions?

A: The programmable timer, coupled with the automatic reset, allows for precise control over tap cycles and effortless operation. After each test, the device resets itself, making repeated measurements time-efficient and highly reliable.

Q: Where can the Tap Density Test Apparatus be used commercially?

A: This apparatus is widely suitable for use in research laboratories, pharmaceutical manufacturing, quality control departments, and the cosmetic industry for assessing powder flow and density characteristics.

Q: Which accessories are included with the Tap Density Test Apparatus model?

A: The box includes two interchangeable graduated cylinders (25 ml and 50 ml), an operation manual, and a power cable, providing immediate functionality for diverse measurement needs.

Q: What is the process for changing cylinders on the Tap Density Test Apparatus?

A: Changing cylinders is streamlined with the quick-lock clamping system. Simply unlock, switch to the desired cylinder volume, and lock it securely for the next test. No tools or complicated procedures are required.
