Two Neck Round Bottom Flask Manufacturer,Supplier and Exporter in India

Product Code : SCL-GF-10326

The 2 Neck Round Bottom Flask 12L / 22L is a laboratory flask used for compatible reaction, heating, distillation, reflux, and vapour-transfer assemblies requiring two neck access points. This flask is specified with a 100mm center neck reference, a 24/40 side neck, and available 12L and 22L capacities.

Product Description

The 2 Neck Round Bottom Flask - 100MM Center - 24/40 Side - 12L, 22L from Lab Glassware Manufacturer is intended for larger-capacity laboratory glassware assemblies where the main vessel needs more than one access point. The confirmed product code is SCL-GF-10326.

The two-neck format allows one neck to connect to the main apparatus while the side neck can support compatible adapters, condensers, stoppers, thermometers, addition funnels, gas inlets, or other verified accessories. Exact glass type, wall thickness, center-neck standard, side-neck geometry, thermal rating, pressure/vacuum suitability, and certifications should be confirmed before final catalogue publication.

Key Features

• Two-neck design: supports multi-connection laboratory setups for reaction, reflux, and distillation work.
• 12L and 22L capacities: available in large-volume formats for compatible laboratory procedures.
• 100mm center neck reference: specified for the main center connection point.
• 24/40 side neck: supports compatible 24/40 jointed accessories or adapters.
• Round-bottom shape: useful for even heating and compatible support assemblies when properly clamped.
• Laboratory flask category: suitable for chemistry, teaching, research, and preparation-room setups.
• Specification-dependent use: heat, vacuum, pressure, and chemical compatibility must be verified before use.

How to Use the 2 Neck Round Bottom Flask

1. Confirm whether the required capacity is 12L or 22L before setup.
2. Inspect the flask for cracks, chips, scratched joints, stress marks, or contamination.
3. Confirm that the 100mm center neck and 24/40 side neck match the connected apparatus.
4. Secure the flask with proper support stands, clamps, and heating equipment before adding liquid.
5. Attach only compatible adapters, condensers, thermometers, or stoppers to the necks.
6. Add the sample or reagent without exceeding the safe working volume defined by the method.
7. Apply heat, stirring, reflux, or distillation conditions only within verified material limits.
8. Allow the flask to cool before disassembly, cleaning, and storage.

Safety note: Do not use this flask under vacuum, pressure, rapid heating, rapid cooling, or hazardous chemical conditions unless the glass type, wall thickness, joints, and full apparatus rating are verified. Use eye protection, gloves, clamps, and a fume hood where required.

Care & Maintenance

• Clean after use with a method compatible with the verified glass type and residue.
• Rinse thoroughly and dry before storage to prevent contamination.
• Store supported in a padded or dedicated large-glassware cabinet.
• Remove from service if any neck, joint, or bulb surface shows cracks, chips, leaks, or stress marks.

Frequently Asked Questions

What is a 2 Neck Round-bottom flask 12L / 22L used for?

A 2 Neck Round Bottom Flask 12L / 22L is used for compatible reaction, reflux, distillation, heating, and vapour-transfer assemblies requiring two access necks.

What does 100mm center mean?

100mm is the confirmed center-neck reference from the product data. Confirm whether it refers to neck diameter, flange size, or joint format before final specification use.

What does 24/40 side mean?

24/40 is the confirmed side-neck joint reference. The side neck should be connected only to compatible 24/40 laboratory glassware or adapters.

Is the flask made from borosilicate glass?

The exact glass type is not confirmed for this specific item. Add borosilicate, quartz, or other material claims only after verification.

Can this flask be used under vacuum?

Vacuum suitability is not confirmed. Use under vacuum only if the flask, joints, wall thickness, and complete apparatus are rated for that condition.

Does this product include stoppers or adapters?

The confirmed item is the 2 Neck Round Bottom Flask. Stoppers, adapters, clamps, condensers, and joint clips should be listed only after verifying the supplied configuration.
