Aspiration/Pressure Transfer Station Model 2511
Standard duty, oil-free station is an economical, portable solution for aspirating or filtering.
Added accessories include 1.2-L autoclaveable collection receiver, hydrophobic inline filter,
automatic shutoff and vacuum regulator to simplify use. All wetted parts are treated for
corrosion protection from moisture. Recommended for aspirating aqueous solutions including
buffers, but not for acidic, basic or organic vapors and gases.
Cell Culture Aspiration Station Model 2515
Cell culture station cat. no. 2515B-75 (115V, 60Hz), 2515C-75 (230V, 50Hz), is an
economical, portable solution for aspirating tissue culture samples. A high flow (34 L/min),
WOB-L piston pump is the heart of this cell culture aspiration station. Added accessories
include a 1.2-L autoclaveable collection receiver, a hydrophobic inline filter, an automatic
shutoff and vacuum regulator to simplify use. All wetted parts are treated for corrosion
protection from moisture. Recommended for aspirating aqueous and bleach solutions, but not
for acidic, basic or organic vapors and gases.
Welch Standard Duty Dry pumps are ideal for pumping water vapor. These WOB-L piston
pumps have a high water vapor tolerance. Each aspiration system comes with inlet liquid trap,
mounted vacuum gauge and vacuum regulator.
The most common reason for vacuum pump failure is ingestion of liquid into the pump
mechanism. Dry vacuum pumps are designed for pumping gases and vapors. Liquids
ingested into the pump mechanism may cause the valves to fail on a Standard Duty Pump. To
help prevent the ingestion of harmful liquids and particles, Welch includes a liquid trap and
hydrophobic filter with all of its aspiration systems.
