Conventional particle size measurement plays an important role in the pharmaceutical industry and other industries and is key to ensuring product quality. Dispersion is critical for any particle size measurement process, and there are two main approaches in laser diffraction systems: wet and dry. If the powder in the dry state is treated and the final product is a dry powder, the dry dispersion method is generally preferred. In the pharmaceutical industry, the active ingredients and excipients are usually treated in a dry form and the final state may be a dry powder, such as a dry powder inhaler. In the early stages of product development, pharmaceutical manufacturers may wish to use less than 100 mg of existing materials.

The particle size of the dry powder sample was measured.

In this application note, we measured only 5 mg of fine medicinal lactose aliquots and achieved good measurement reproducibility – meeting the reproducibility requirements of the ISO laser diffraction standard guidelines. We chose fine lactose as the active ingredient of the drug and a high-adhesive powder modeling material that is difficult to disperse.

Vein Finder

The vein viewer uses strong infrared light to detect dorsal venous rete of hand, so that health care workers can easily see the blood vessels and find IV sites for needle placement thus to achieve successful injections.

For people whose veins are not easily found (like infants, fat people, people with edema, etc.). patients who cannot move freely, and other accidental occasions.The product can be widely used in hospitals (like ICU.ambulance.neurology. orthopedics department and sureical department.rescue service for fire-fighting and soldiers. Especially useful under darkly lit environments or smoggy circumstances.
