Carboy with Vacuum Port - 20,000 Milliliters - (65/50) Made of Borosilicate

The 20,000 milliliters Carboy with Vacuum Port is a large-capacity borosilicate 3.3 laboratory vessel with a 20,000-milliliter nominal volume, 65/50 ground-glass joint, and dedicated vacuum connection. Its size provides substantial working capacity for compatible liquid handling, collection, storage, filtration, or transfer setups.

The 65/50 joint should be paired only with compatible laboratory components using the corresponding taper designation. The vacuum port can be incorporated into an appropriately designed reduced-pressure system, but the presence of a vacuum connection does not by itself establish a maximum vacuum or pressure rating. Whole-system suitability depends on the vessel condition, connected glassware, tubing, seals, pump, and procedure.

Because a filled 20,000 milliliters Carboy with Vacuum Port can be heavy, plan its location and support before adding material. Use suitable handling methods and avoid carrying the vessel by the neck, joint, or vacuum connection. Confirm chemical compatibility for the substance being held and leave appropriate headspace for the procedure.

Inspect the entire carboy before every use, including the base, sidewalls, neck, 65/50 joint, and vacuum port. Chips, cracks, deep scratches, impact damage, or damaged sealing surfaces are reasons to remove the vessel from service. Do not apply reduced pressure to damaged glassware. Use appropriate shielding and safety procedures for vacuum work and avoid inappropriate thermal shock.

The 20,000 milliliters Carboy with Vacuum Port is a high-capacity option for compatible laboratory systems requiring a 65/50 connection. Browse related vessels in our Borosilicate Glass Laboratory Equipment collection.

Frequently Asked Questions

Which joint and capacity are listed?
The listing specifies a nominal capacity of 20,000 milliliters, borosilicate 3.3 glass, and a 65/50 ground-glass joint.

Does the vacuum port establish an operating limit?
No. Obtain the documented vessel rating and confirm the complete system is suitable for your intended pressure differential.

How should I handle this large vessel?
Plan stable support before filling. Do not carry it by the neck, joint, or vacuum port, and inspect the glass before each use.
