BD‑93B Scott Volumeter Bulk Density Tester | ASTM B329 ISO3923‑2 Powder Apparent Density Meter-Labcan Scientific

Product Description

BD‑93B Scott Volumeter, also named Scott apparent bulk density tester, implements the internationally‑recognized Scott volumeter method to measure loose apparent density of powders. Unlike tapped density which applies mechanical tapping compaction, Scott density represents powder natural packing status under pure gravity without any external compression force. This parameter directly indicates powder flow‑behavior, inter‑particle interaction and filling performance, which has great guiding significance for powder pressing, mixing, feeding and packaging production processes. #### Working Principle Sample powder is poured into the top feeding funnel, first passing through a standard‑size sieve to break large lumps and filter oversized particles. Then powder flows into the transparent baffle box equipped with four inclined glass baffles. These baffles repeatedly divert and disperse powder stream, break soft agglomerates, prevent particle segregation, and allow powder to fall down uniformly in a fully loose condition. Powder free‑falls from fixed height into the 25 mL calibrated receiving cup. Once the cup is overflowing, excess powder is scraped level with the top edge by a straight scraper. Weigh the powder inside cup on external analytical balance. Divide sample mass by cup volume to obtain Scott apparent bulk density value. #### Instrument Construction & Material Advantage All parts that directly contact powder sample, including feeding funnel, sieve frame and calibrated receiving cup, are manufactured from high‑quality 304 stainless‑steel. It delivers excellent anti‑corrosion performance against most inorganic powders, pharmaceutical excipients and pigment materials; meanwhile avoids metal contamination to samples. The baffle box adopts transparent housing structure. Operators can visually observe powder flowing state during the whole test, quickly identify abnormal phenomena such as bridging, blocking or uneven flow, so as to judge whether the sample is suitable for Scott volumeter testing. Four pieces of optical glass baffles have smooth surface, low powder adhesion, and can be disassembled separately for thorough cleaning to avoid cross‑contamination between different batches or different sample types. Built‑in spirit level together with four adjustable leveling feet ensure the whole unit keeps horizontal during operation. Deviation of installation level will cause uneven powder falling and bring repeatability error; this leveling mechanism guarantees consistent test conditions for every measurement. #### Operation & Lab Compatibility BD‑93B Scott Volumeter is a gravity‑driven manual test device requiring no power supply. It matches with external analytical balance (not included) for mass weighing. The complete test workflow is simple, but strictly standardized to meet international standard requirements. All key dimensional parameters including funnel outlet size, vertical drop height from funnel to receiving cup, baffle installation angle are strictly manufactured according to ASTM B329 dimension requirements. Components can be quickly disassembled without special tools for cleaning and sample change‑over, which improves laboratory testing efficiency especially for frequent multi‑batch testing scenarios. #### Standard Compliance & Application Value This instrument fully complies with ASTM B329, ISO 3923‑2, USP <616> Method 2, EP 2.9.34‑2 and GB/T 1479.2‑2011. It can be used for quality control in production site as well as pharmacopoeia‑compliant laboratory testing. Please note the method limitation: Scott volumeter is suitable for free‑flowing powder. For sticky, highly cohesive, damp powder that tends to bridge and block inside baffles, Scott method is not applicable. In such situation, it is recommended to combine tapped bulk density test to evaluate powder physical properties comprehensively. For manufacturers, R&D teams and third‑party testing institutes, BD‑93B provides repeatable, comparable Scott apparent density data, supporting raw‑material incoming inspection, new‑formula development, batch‑to‑batch consistency verification and product technical‑document preparation.
