Isingeniso Se-Flask Volumetric

Igabha lomthamo (iflask yokulinganisa noma iflaskhi ethwelwe iziqu) ucezu lwengilazi ye-laboratory, uhlobo lwebhodlela laselebhu, elinganiselwe ukuqukatha ivolumu eqondile ezingeni lokushisa elithile. Amabhodlela weVolumetric asetshenziselwa ukuxubana okunembile nokulungiswa kwezixazululo ezijwayelekile.

Imiyalo

Ngaphambi kokusebenzisa ibhodlela levolumu, kudingeka amasheke amabili alandelayo.

1. Umthamo webhokisi lomthamo uhambelana nalokho okudingekayo.

2. Bheka ukuthi ukhokho uqinile futhi awuvuza yini.

Beka amanzi ebhodleleni eduze nolayini wokumaka, xhuma istobha ngokuqinile, bese usivumela sime imizuzu emibili. Hlola nephepha lokuhlunga elomile eceleni komthungo webhodlela ukuze ubone ukuthi akukho ukuvuza kwamanzi. Uma ingavuzi, vula ipulagi engu-180 °, uyivale ngokuqinile, uyihlanekezele, bese uvivinya ukuvuza kule ndlela. Isitobha esiqinile kufanele sigcinwe endaweni ephephile. Kunconywa ukubopha intambo entanyeni yebhodlela ukuyivimba ukuthi ingawi noma ixutshwe nezinye izitobha.
