Iindaba zeshishini

Iimitha ze-benchtop kudala zazingamandla okusebenza kwiilabhoratri zohlalutyo, uqinisekiso lomgangatho wemizi-mveliso, kunye namaziko emfundo. Ngokungafaniyo noogxa abaphathwayo, iimitha ze-benchtop zibonelela ngozinzo oluphezulu, uluhlu olwandisiweyo lokulinganisa, kunye nezakhono ezininzi zeeparamitha. Nokuba ulinganisa i-pH, i-conductivity, ioksijini enyibilikileyo, okanye ugxininiso lwe-ion, imitha yebhentshi eyomeleleyo iyimfuneko kwizicelo ezifuna uchaneke ophezulu kunye nokuphinda-phinda. Kwesi sikhokelo sibanzi, sintywila nzulu kwindalo yonke yee-benchtop metres, sivavanya amandla azo, imida, kunye neemeko ezifanelekileyo zokusebenzisa - lonke eli xesha siqaqambisa izisombululo ezivela kubavelisi abathembekileyo abafana neShanghai DDK Scientific Instruments Co., Ltd.

Iimitha zepokotho zibe zizixhobo eziyimfuneko kuwo wonke amashishini apho imilinganiselo ekhawulezayo, ethembekileyo, nephathwayo ifuneka. Nokuba zisetyenziswa ngabahloli bendalo esingqongileyo, amagcisa aselabhorethri, iingcali zolimo, okanye iinjineli zemizi-mveliso, ezi zixhobo zihlangeneyo zibonelela ngofundo olukhawulezileyo lweeparamitha ezinje nge-pH, ukuqhuba, ubushushu, okanye izinto eziqinileyo ezinyibilikisiweyo. Ngokungafaniyo nezixhobo zebhentshi ezinkulu, iimitha zepokotho zenzelwe ukwenza lula ngaphandle kokuncama ngokuchanekileyo.

Isisombululo se-pH se-buffer luhlobo lwesisombululo esinokugcina ixabiso le-pH lizinzile. Ukuba ixabiso elincinci le-asidi okanye isiseko songezwa kwesi sisombululo, okanye ixabiso elincinci ...
