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。
特点和优势
应用范围
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)
Particle Size Range
Related to size of powder to be dispersed. Maximum size is approximately 50-μm aerodynamic diameter; particles smaller than 1 μm do not deagglomerate efficiently.
Turntable Rotation
Clockwise or counterclockwise, between 0.25 and 3.3 rev/hour; 2.5 to 33.3 rev/hour with optional high-speed motor
Power Requirements
100, 120, 220, 240 VAC; 50 to 60 Hz; 20 W
Dimensions (L x W x H)
386 × 432 × 343 mm (15.2 × 17 × 13.5 in.)
Weight
18 kg (39 lbs)
It is recommended that the powder dispersers described in this brochure be used with the TSI’s Air Supply System Model 3074B.
