Kitul de spray nazal (gol) este un consumabil de laborator \u0219i nu o substan\u021b\u0103 chimic\u0103: tehnic este un set de spray gol cu \u200b\u200bun flacon de 5 ml \u0219i un cap de pomp\u0103 cu capac protector. \u00cen cercetarea \u0219tiin\u021bific\u0103, un astfel de set este utilizat ca ambalaj de referin\u021b\u0103 \u00een cercetarea formul\u0103rilor \u0219i pentru caracterizarea interac\u021biunii dintre nebulizare \u0219i ambalare. Acest set este oferit complet gol, exclusiv pentru scopuri de laborator \u0219i cercetare.<\/p>\n
Setul este un a\u0219a-numit sistem de \u00eenchidere a recipientelor: combina\u021bia dintre un recipient \u0219i \u00eenchiderea asociat\u0103 func\u021bional cu acesta. Sticla este fabricat\u0103 din plastic \u0219i are un volum nominal de 5 ml; aceasta g\u0103zduie\u0219te o pomp\u0103 de pulverizare cu guler, un tub de imersie \u00een partea de jos \u0219i un capac de protec\u021bie care men\u021bine ie\u0219irea \u00eenchis\u0103. Spre deosebire de o sticl\u0103 cu capac cu filet, comportamentul aici este determinat nu numai de material, ci \u0219i de mecanic\u0103: pompa, ie\u0219irea \u0219i volumul mort fac parte din sistem. \u00cen cercetarea formul\u0103rilor, ambalajul este, prin urmare, considerat o variabil\u0103, mai degrab\u0103 dec\u00e2t o carcas\u0103 neutr\u0103.<\/p>\n
Principiul de func\u021bionare este pur fizic: ap\u0103sarea capului pompei creeaz\u0103 o diferen\u021b\u0103 de presiune care atrage lichidul \u00een tubul ascendent \u0219i \u00eel for\u021beaz\u0103 printr-o deschidere \u00eengust\u0103. Jetul de lichid care iese este instabil \u0219i se descompune \u00een pic\u0103turi; o camer\u0103 vortex din fa\u021ba deschiderii confer\u0103 acestui nor de pic\u0103turi un model conic. V\u00e2scozitatea, tensiunea superficial\u0103 \u0219i densitatea, \u00eempreun\u0103 cu geometria deschiderii, determin\u0103 fine\u021bea atomiz\u0103rii. Deoarece ace\u0219ti parametri sunt m\u0103surabili, un kit gol este un instrument potrivit pentru compararea propriet\u0103\u021bilor lichidului \u0219i a comportamentului de ambalare. Prin urmare, kitul de spray nazal este utilizat \u00een cercetarea \u0219tiin\u021bific\u0103 ca recipient de referin\u021b\u0103 \u0219i ca ajutor \u00een configura\u021biile experimentale.<\/p>\n

Within our range, this set falls under laboratory supplies and not under research compounds: it contains no dust and no chemical material is supplied. Researchers combine the set with other consumables and with liquids that have a specific function in the setup. Other items within the same line have been selected based on closure type, material choice, or volume; they differ in construction and in the extent to which they can influence a measurement.<\/p>\n

Because the set is empty, there is no chemical content and no expiration date; however, attention is required for the cleanliness of the internal surface. New plastic parts may contain dust or mold residue, and it is customary to rinse and dry the set before use.<\/p>\n Store the parts dry and dust-free at room temperature, in the original packaging and protected from prolonged sunlight, which damages plastic over time. Handle the material with standard laboratory precautions: work in a clean environment, use appropriate personal protective equipment, and prevent cross-contamination between sets that have come into contact with different fluids. Keep the packaging out of reach of unauthorized persons.<\/p>\n Compozi\u021bie \u0219i rezultate de laborator<\/h2>\nA purity percentage does not apply to this set: it concerns packaging and atomizer material, not a chemical compound. The relevant specifications are the nominal volume, the construction of the pump and bottle, and the fact that the set is supplied empty.<\/p>\n |
