NALGENE可修復(fù)式手動(dòng)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)?？烧{(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(cè)量數(shù)據(jù)，排氣口上帶有活動(dòng)蓋，真空觸發(fā)釋放時(shí)不會(huì)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. Removable cover on exhaust port and trigger to release vacuum without disconnecting pumps from the line. Can be disassembled for repair or replacement of internal parts. See Cat. No. 6132-1000 for repair kit. Nozzle fits standard
