NALGENE可修復(fù)式手動真空泵（帶壓力表）6132-0020

（6132 Repairable Hand-Operated Vacuum Pumps with Vacuum Gauge）

采用新式手柄設(shè)計(jì)，更加經(jīng)久耐用。機(jī)身材質(zhì)是聚氯乙烯，能快速達(dá)到并保持635mm HG的真空狀態(tài)。單手操作即可完成真空觸發(fā)釋放，食指輕觸即可釋放真空狀態(tài)。可調(diào)節(jié)真空釋放率。6132-0010的泵送率為15CC/沖程，排氣口處得正壓為7psig（.48bar）.6132-0020的泵送率為36CC/沖程，排氣口處的正壓力為0.84bar.全空口壓力為兩次沖程后得到的測量數(shù)據(jù)，排氣口上帶有活動蓋，真空觸發(fā)釋放時不會斷開真空泵與管線的鏈接。其噴嘴可連接1/4英寸的標(biāo)準(zhǔn)內(nèi)鏡的膠管，隨附兩英尺長的透明塑料管
Smaller size （Cat. No. 6132-0010） has pumping rate of 15 cc/stroke and 7 psig （.48 bar） positive pressure at the exhaust port. Larger size （Cat. No. 6132-0020） has rate of 36 cc/stroke and 12 psig （.84 bar） positive pressure at the exhaust port. Full blank port pressure is obtained with only two strokes.
