Syringe filler

During analysis of gases dissolved in transformer oil by HAS (head space analysis) method it is necessary first of all to fill the syringe with transformer oil by gas-carrier and then after obtaining equilibrium distribution of gases, dissolved in the oil, between liquid and gas phases insert gas phase into the chromatograph (blow the doses of injection valve of chromatograph). Moreover, syringe filling operations and sample injection are done without access of air. During syringe filling there is possibility to fixate the plunger on certain volume.
