产品详情

小规模粉末扩散器* 3433 (SSPD) 通过使用文丘里管吸引器从转盘提升粒子产生少量粉末。转盘以变速旋转来控制气溶胶浓度。SSPD 中形成的剪切力足以分解 0.5 至 50 µm 粒径范围内的大多数干燥粒子。

提供可选转盘选择，以满足特殊需求。由于 SSPD 只分散少量样本，因此它特别适用于涉及稀有、贵重或危险材料的研究。它还有效地分散用于校准测量仪器的聚苯乙烯乳胶 (PSL) 球。与本公司的 Aerodynamic Particle Sizer® (APS™) 粒径谱仪配套，用于干粉的粒径分布测量。

技术参数：
Output Concentration Range
  0.3 to 4 mg/m³ with standard motor; 3 to 40 mg/m³ with alternate motor
Powder Feed Rate Range
  3 to 90 mg/hr
Carrier Gas Flow Rate Range
  12 to 21 liters/min at 138 KPa (20 psi)
