Lab glassware bubblers are components that prevent a liquid (usually mineral or silicone oil) from "backflowing" into the prior components in the glass system. Bubblers typically have hose connections as their intake opening, often with a built-in stopcock so that the inflow can be halted as desired.
In chemistry glass applications, bubblers are used to prevent the cleanup or contamination that results from unwanted backflow.
Our lab bubblers include various styles for compatibility with a wide variety of glassware systems.
Adapter, Mineral Oil Bubbler with 10mm O.D. hose connection.
Used to monitor gas flow to reactions while providing a vent to the atmosphere. Reservoir head prevents oil from being sucked back into the system. Volume below the sidearm is approx 40mL. Bubbler has an 8mm OD top and side tubulations.
Bubbler has an integral valve to control the flow of inert gas into the system. Bubbler requires a minimal amount of oil due to the inner tube being within 5mm of the bottom. Both sidearms are 9mm OD for use with 3/8" Cajon® fittings. Overall height is approx. 220mm.
Similar in design to AF-0513 but with two oil reservoirs. Bubbler is approx 125mm W x 135mm H. Hose connections are 9mm OD at the middle serration.
High capacity check valve bubbler keeps oil and air from being drawn into a reaction system when negative pressure is developed. Bubbler has two 1/2" swagelock type fittings on top permitting one side to be connected to the nitrogen source and one side to the reaction system. The bubbler is...
Bubbler, Hose Connection, Stopcock, with small ball joints to prevent mineral oil being sucked back under sudden negative pressure into the system.
Used to monitor gas flow to reactions while providing a vent to the atmosphere. Bubbler has a "T" connection at the top to allow it to be mounted in-line while the reservoir head prevents oil from being sucked back into the system. Volume below the sidearm is approx 40mL. Bubbler...
Bubbler, Mineral Oil, with 10mm O.D. hose connection.
Used for the purging of Airfree or vacuum apparatus with an inert gas. The pressure release valve is connected on one side to the low pressure gas source and the other side to a manifold or reaction vessel. The check valve prevents oil and air from being pulled into the...
Unique design of bubbler allows for fine control of purge gas within an inert gas system such as a manifold. Purge gas enters bubbler through hose connection (A) and exits thru connection (B) which is connected to manifold. The large capacity of the main chamber (C) allows for rapid purging...
Bubbler, PTFE Stopcock, with small ball joints to prevent mineral oil being sucked back under sudden negative pressure into the system.
Bubbler has an adjustable inner tube with a #9 Chem-Thread. Taper at bottom of reservoir allows for use of a minimal amount of oil. Complete bubbler consists of the lower reservoir, adjustable inner tube, compression cap and Viton o-ring.
High capacity check valve bubbler keeps oil and air from being drawn into a system when negative pressure is developed. It is most often used when evacuating and purging apparatus with an inert gas. The bubbler is filled with oil (mineral or silicone) to a level slightly above the top...
Horizontal design of bubbler allows for in line connection and purging of apparatus. Hose connection has a 9mm OD middle serration. Complete with standard taper inner joint.
Used to monitor gas flow to reactions while providing a vent to the atmosphere. Reservoir head prevents oil from being sucked back into the system. Standard taper inner joint is for use in single or multi-neck flasks. Hose connection has a 9mm OD middle serration. The 24/40 jointed bubbler is...
Used for the control of carrier gases. Projection at top breaks bubbles. Supplied complete with rubber bulb. Hose connection has a O.D. of 9mm at the middle ring.
Micro impinger designed for sampling of small volumes of air at low jet velocity, as per EPA Method 6. Impinger bottle is graduated from 5 to 30mL in 5mL subdivisions. Both the bottle and stopper have 24/40 standard taper joints. The nozzle being replaced with an extra coarse fritted gas...
