Mefuta ea lifilimi tsa sterile syringe

Frarile syringe craringe e ka khethoa ho latela mekhoa e mengata:

1. Sebopeho sa lintho tse bonahalang

Lisebelisoa tse sebelisoang bakeng sa membrane le matlo a na le tšusumetso e kholo ts'ebetsong ea filthara le ho ikarabella bakeng sa kopo e itseng:

Nylon: E tsebahala ka matla a eona a bohlokoa le ho hanyetsa ka Chection. E loketse li-solvel tse futhumetseng le tsa manyolo.

PTFE.

PES (Polyettherulfone): hydrophphilic, tekanyo e phahameng e phallang; E loketse tharollo ea mahe le mecha ea lihloliloeng.

Pvdf (Polyvinlidene Fluoride): Na thepa e tlase ea protheine e tlamang, e loketseng lits'ebetso tsa likopo tsa tlhaho.

Mce(e tsoakiloeng): E loketse tharollo ea metsi; hangata e sebelisoa likopi tsa Microbioiggy.

2. Sekepe sa pore

Melemo ea ho sebelisa li-syrive Syrits

Ho na le menyetla e mengata ea ho sebelisa li-syriwa Syrits:

1. Mohlala oa mohlala

Ka ho tlosa li-kidminant le di-ditlhents, litšila tsena li thusa ho boloka botšepehi ba li-sampole tse hlokolosi, bo bakang sephetho se tšepahalang sa mahlale a sa tšepahaleng.

2. E bonolo ebile e potlakile

Lifilimi tsa sterringe li fana ka mokhoa o potlakileng le o bonolo oa ho lokisetsoa ntle le tlhoko ea lisebelisoa tsa ho fifala kapa lisebelisoa.

3. Sebetsa sa theko
