Jiangsu Yongjian Pharmaceutical Technology Co., Ltd
Jiangsu Yongjian Pharmaceutical Technology Co., Ltd., tsim nyob rau hauv Lub peb hlis ntuj 2012, yog ib tug high-tech enterprise integrating R & D, ntau lawm thiab muag khoom.Nws yog feem ntau koom nrog hauv kev tsim khoom, kev tsim kho thiab kev tsim cov txheej txheem tsim khoom ntawm cov khoom siv ntuj tsim, tshuaj suav tshuaj siv cov ntaub ntawv thiab tshuaj impurities.Lub tuam txhab nyob rau hauv Tuam Tshoj Pharmaceutical City, Taizhou City, Jiangsu Province, nrog rau 5000 square meter ntau lawm puag thiab 2000 square meter R & D puag.Nws tsuas yog ua haujlwm rau cov koom haum tshawb fawb loj, cov tsev kawm qib siab thiab cov khoom lag luam decoction ntau lawm thoob plaws lub tebchaws.
Txog tam sim no, peb tau tsim ntau tshaj 1500 hom natural compound reagents, thiab muab piv thiab ntsuas ntau tshaj 300 hom ntaub ntawv siv, uas tuaj yeem ua tau raws li kev soj ntsuam txhua hnub ntawm cov chaw tshawb fawb loj, cov chaw soj ntsuam hauv tsev kawm ntawv thiab cov khoom siv decoction.
Raws li lub hauv paus ntsiab lus ntawm kev ntseeg zoo, lub tuam txhab vam tias yuav koom tes nrog peb cov neeg siv khoom.Peb lub hom phiaj yog ua haujlwm rau kev kho tshiab ntawm cov tshuaj suav tshuaj.
Advantageous Business Scope Ntawm Lub Tuam Txhab:
1. R & D, ntau lawm thiab muag khoom siv tshuaj siv tshuaj ntawm cov tshuaj suav tshuaj;
2. Customized tshuaj suav tshuaj monomer tebchaw raws li tus neeg siv khoom tus yam ntxwv
3. Kev tshawb fawb txog cov txheej txheem zoo thiab cov txheej txheem kev txhim kho ntawm cov tshuaj suav tshuaj (cog) extract
4. Kev koom tes thev naus laus zis, hloov pauv thiab tshawb nrhiav tshuaj tshiab thiab txhim kho.
Kev Pabcuam Yongjian
Customized kev pab cuam ntawm tshuaj siv cov ntaub ntawv ntawm tsoos suav tshuaj
Jiangsu Yongjian Pharmaceutical Technology Co., Ltd. yog feem ntau koom nrog hauv kev tshawb fawb ntawm cov tshuaj nquag ntawm cov tshuaj suav tshuaj rau ntau tshaj kaum xyoo.Txog tam sim no, lub tuam txhab tau ua qhov kev tshawb fawb tob txog ntau dua 100 hom kev siv tshuaj suav tshuaj, thiab tau rho tawm ntau txhiab yam tshuaj.
Lub tuam txhab muaj cov neeg ua haujlwm R & D sab saum toj thiab cov khoom siv tshuaj ntsuam xyuas zoo tshaj plaws hauv kev lag luam, thiab tau ua haujlwm ntau pua lub tsev tshawb fawb txog kev tshawb fawb.Nws tuaj yeem ua tau sai thiab ua tau raws li cov neeg siv khoom xav tau.
Tshuaj impurity sib cais, kev npaj thiab kev pom zoo kev pab cuam
Impurities nyob rau hauv cov tshuaj yog ze ze rau qhov zoo, kev ruaj ntseg thiab stability ntawm cov tshuaj.Kev npaj thiab qauv kev lees paub ntawm impurities hauv cov tshuaj tuaj yeem pab peb nkag siab txog txoj hauv kev ntawm impurities thiab muab lub hauv paus rau kev txhim kho cov txheej txheem ntau lawm.Yog li ntawd, kev npaj thiab kev sib cais ntawm impurities yog qhov tseem ceeb heev rau kev tshawb fawb txog tshuaj thiab kev loj hlob.
Txawm li cas los xij, cov ntsiab lus ntawm impurities nyob rau hauv cov tshuaj yog tsawg, lub hauv paus yog dav, thiab cov qauv yog feem ntau zoo ib yam li lub hauv paus ntsiab lus.Dab tsi tshuab siv tau los cais thiab ntxuav tag nrho cov impurities hauv cov tshuaj ib los ntawm ib qho thiab sai sai?Cov txheej txheem thiab cov txheej txheem twg yog siv los lees paub cov qauv ntawm cov impurities no?Qhov no yog qhov nyuaj thiab kev sib tw uas tau ntsib los ntawm ntau lub chaw muag tshuaj, tshwj xeeb tshaj yog cov chaw muag tshuaj ntawm cov tshuaj cog thiab tshuaj suav patent.
Raws li cov kev xav tau zoo li no, lub tuam txhab tau tsim cov tshuaj impurity cais thiab purification cov kev pab cuam.Relying ntawm nuclear magnetic resonance, huab hwm coj spectrometry thiab lwm yam khoom siv thiab thev naus laus zis, lub tuam txhab tuaj yeem txheeb xyuas cov qauv ntawm cov khoom sib cais, kom ua tau raws li cov kev xav tau ntawm cov neeg siv khoom.
SPF Tsiaj Kev sim
Kev tsim kho thaj tsam ntawm thaj chaw sim tsiaj yog 1500 square metres, suav nrog 400 square metres ntawm thaj chaw soj ntsuam SPF thiab 100 square metres ntawm P2 qib cell kuaj.Coj los ntawm cov kws tshawb fawb ntawm Tuam Tshoj Pharmaceutical University, nws tsim ib pab pawg kws tshaj lij nrog ntau tus neeg rov qab los.Muab cov qauv tsiaj zoo, kev sim tsim, tag nrho cov haujlwm thiab lwm yam kev pabcuam rau biomedical scientific tshawb fawb, kev qhia thiab kev tsim kho kev lag luam.
