GEMINI 1 Ph 200 torr Dry Vacuum Pump
Welch, 2060B-01, GEMINI 1 Ph 200 torr Dry Vacuum Pump with North America Plug 115VBring vacuum to where you need it. GEMINI pumps operate on DC power and are readily used with a car adapter or 120VAC adapter. Excellent vacuum for filtration or sampling - 190 torr, 13 l/min. Small, lightweight, portable, includes gauge and vacuum regulator. Polyarlyamide heads, fluorpolymer elastomer diaphragms, tubing, valves.FeaturesPowerful, portable, economicalAdvanced chemical resistanceApplicationsVacuum FiltrationMany filtrations require only minimal vacuum to proceed; deep vacuum is not required. Vacuum pump flow required is roughly proportional to the total surface area of filters being used. Filtration of particulate-clogging samples can be improved somewhat with deeper vacuum, but a combination of larger filter surface area, smaller samples, and sequential use of decreasing porosity filter papers may also be required for timely filtration. Choose a standard duty vacuum pump for aqueous vapors; use a PTFE pump for resistance to harsh chemicals. ... Show More Show Less
