Product Code : SCL-GF-10366

The Heavy Wall Filter Flask is a Boro 3.3 laboratory vacuum flask used for vacuum filtration, suction filtration, filtrate collection, and solid-liquid separation. It is specified in 1L, 2L, and 5L sizes with a 1/2" barb connection for compatible vacuum tubing setups.

Product Description

The 1L, 2L, 5L Boro 3.3 Heavy Wall Filter Flask 1/2" Barb from Lab Glassware Manufacturer is intended for vacuum-assisted filtration workflows in chemistry, research, QC, pharmaceutical, and teaching laboratories. The supplied product name confirms Boro 3.3 glass, heavy-wall construction, 1L / 2L / 5L capacity options, and a 1/2" barb reference.

Heavy-wall filter flasks are used with compatible funnels, rubber connectors, glass joints, tubing, clamps, and vacuum sources. Related verified product pages list filter flasks and Buchner flasks for vacuum work. Exact vacuum rating, barb material, side-arm construction, neck finish, wall thickness, and certificate documentation should be confirmed before final catalogue approval.

Key Features

• Boro 3.3 glass: specified in the product name for laboratory chemical and thermal-resistance context.
• Heavy-wall flask body: intended for vacuum filtration workflows where reinforced flask construction is required.
• Three capacity options: available as 1L, 2L, and 5L for different filtration volumes.
• 1/2" barb reference: intended for compatible vacuum tubing connection.
• Side-arm filtration use: supports vacuum-assisted filtrate collection when connected to a verified vacuum source.
• Laboratory workflow support: suitable for chemistry, QC, research, pharmaceutical, and education labs.
• Specification-dependent safety: vacuum rating, tubing fit, flask condition, and glass compatibility must be verified.

How to Use the Heavy Wall Filter Flask

1. Select the correct 1L, 2L, or 5L flask for the expected filtrate volume.
2. Inspect the glass body, neck, side arm, barb, and base for cracks, chips, scratches, or stress marks.
3. Fit a compatible funnel, adapter, or stopper onto the flask neck.
4. Attach verified vacuum tubing securely to the 1/2" barb.
5. Place filter paper or the correct filter medium in the funnel.
6. Apply vacuum gradually and check for leaks before adding the sample.
7. Pour the sample steadily and avoid overfilling the receiving flask.
8. Release vacuum before disassembly, then empty, clean, dry, and store the flask.

Safety note: Use only undamaged, vacuum-suitable glassware. Do not use cracked glass, mismatched tubing, hot liquids, incompatible solvents, pressure-generating samples, or unverified vacuum sources. Wear goggles, gloves, and a lab coat, and use a shield where required.

Care & Maintenance

• Clean immediately after filtration to prevent residue and crystallized deposits.
• Inspect the barb and side-arm area before every vacuum setup.
• Store padded and upright to protect the heavy glass body and connection point.
• Remove from service if cracks, scratches, chips, leaks, or vacuum-stress marks appear.
