Brief introduction Tap density is one of the important indicators of the quality of the powder , a tap density measurement , refers to an amount of powder into the container , the vibration under certain conditions until the volume of the container is no longer to reduce the powder , the powder read the volume , weight and then divided by the volume of the powder tap density is obtained . JZ-7 Powder tap densitometer by a precision variable speed motor , stainless steel guide frame and other components , solid structure is reasonable, simple , test data managed by the computer . Instrument has two work stations, which can measure the two samples. Features Technical principle: tap density refers to the powder filled in the container in a predetermined condition is the density after tapping . JZ-7 -type tap densitometer meet the national standard GB / T 5162-2006/ISO3953: 1993, with reference to the United States Pharmacopoeia , European Pharmacopoeia standard works. Instrument features : JZ-7 Powder tap densitometer is mostly composed of 304 pieces , solid structure is reasonable, simple , accurate test . When the first samples of the powder into the test tube , and then the sample tube into the instrument working position , press the start button , the powder particles without damaging the original form , the sample tube and down repeatedly inertial motion , when the gap between the particles tend to the limit , the powder is no longer reduced volume , the volume of the powder after vibration , the weight data is input to a computer , automatically calculates the tap density of powders , bulk density results . Technical parameters Measurement accuracy: precision error <± 1%; the test sample tube in a cycle automatically rotated a certain angle , to ensure powder appear before the state level, so as to ensure a high degree of measurement accuracy noodles . Tap Time: tap the length of time can be adjusted by a microcomputer counter . Vibration frequency: 300 times / min Note : You can also buy devices with adjustable frequency Vibration amplitude : 3mm ± 0.2 mm Sample tube : Configure three kinds of glass sample tube , the volume was 25mL 50mL 100mL Instrument appearance : length 450mm width 280mm height 230mm Power supply : AC220V ± 10V 50HZ 50W Use of environmental requirements : relative humidity less than 85 %, no condensation Other requirements: clean environment no smoke , no mechanical vibration source or around sources of electromagnetic interference .
