Productbeschrijving:
Qualtech-producten voor de industrie Powder Angle of Repose Tester is a precision powder test instrument to determine the flow-ability and flow properties of powders and granular materials including pharmaceutical powders, cosmetic powders, flour, sugar, coffee, powdered milk, toner, metal powders and related materials as well as naturally present powders and granules including snow, dust, sand, volcanic ash and related materials.
De Rusthoek is the angle of the conical pile of powder or granules created when a specified amount of powder is poured onto a horizontal surface and it indicates the amount of interparticulate friction between individual particles representing the flow properties of powders and related materials.
Deze professional Powder Angle of Repose Determination is designed and engineered offering a precision engineered high quality stainless steel design combined with a precision engineered funnel, a precision protractor, an integrated level and a powder tray to ensure high accuracy, high repeatability, user-friendly application, user-friendly sample handling, an ergonomic design, reliable performance, longevity and much more.
This precision Powder Angle of Repose Tester is designed and engineered in accordance with international test standards including:
- ASTM D6393-08 (Standaardtestmethode voor de karakterisering van bulkvaste stoffen aan de hand van Carr-indexen)
- ISO 4324 (Oppervlakteactieve stoffen — Poeders en korrels — Bepaling van de rusthoek)
- ISO 8398 (Vaste meststoffen — Bepaling van de statische hellingshoek)
- DIN EN 12047 (Vaste meststoffen – Bepaling van de statische hellingshoek)
- Amerikaanse Farmacopee – USP 1174
- Europese Farmacopee – EP 2.9.36/17
ASTM ISO USP Powder Angle of Repose - Orifice Diameter:
We provide precision equipment you need for repeatable powder testing. While we offer a range of precision engineered Funnel Sizes up to 25mm, choosing the right Orifice is about more than just getting the powder to fall, it's about the integrity of your data.
The 5mm Standard: The validated Choice
Our 5.0mm precision engineered Orifice is the center of professional powder characterization.
Global Comparability: Most international standards including ISO 4324 and USP <1174> are built around the 5mm opening. Using this size ensures your results can be compared with labs and suppliers and your customers and clients worldwide.
Controlled Flow: A 5mm stream prevents 'Cone Collapse'. It allows particles to settle naturally, giving you a true measurement of the powder's internal friction.
Our Tip: Even for 'sticky' powders, we recommend using our included Stainless Steel Stirring Rod with the 5mm Precision Funnel. This maintains standard compliance while gently assisting the flow.
When to Choose a Larger Orifice (10mm - 25mm)
We know that in the real world, some industrial powders are extremely cohesive and simply will not pass through a 5mm opening. We offer larger custom engineered Precision Funnels with an Orifice Diameter of up to 25mm to ensure you can still complete your tests, however, test results may be outside of recognized Test Standards and primarily helpful for your laboratory's internal QC.
What you should know before choosing a larger size:
Beyond the Standard: Using a larger Orifice usually moves your test outside of recognized ISO/USP specifications. You are creating an 'Internal Standard' rather than a globally comparable one.
The 'Avalanche' Effect: A 10mm or larger stream is much heavier. The weight of the falling powder can compress the pile, often resulting in a slightly shallower angle than a standard test would show.
Why We Tell You This:
Other shops might simply sell you a larger funnel without a second thought. We believe in Honest Engineering. We want you to have the funnel that works for your material, but we also want you to know exactly how that choice affects your scientific data.
Whether you need the precision engineered Orifice with a diameter of 5mm as recognized standard or the convenience of a larger precision engineered customized Funnel, we have the precision equipment to get the job done.
