FAQs

1. What is the maximum vacuum pressure the Whatman SF100 suction flask can handle?

The flask is designed to withstand standard laboratory vacuum pressures up to 760 mmHg, but always ensure gradual pressure application to prevent stress fractures.

2. Can this flask be used with aggressive solvents like acetone or hydrochloric acid?

Yes, the borosilicate 3.3 glass construction resists most laboratory solvents, including acetone, hydrochloric acid, and sodium hydroxide, though prolonged exposure to hydrofluoric acid should be avoided.

3. Is the side arm diameter compatible with standard rubber tubing?

The side arm features a 24/29 joint size, which is compatible with most standard laboratory rubber or silicone tubing used in vacuum filtration setups.

4. How should the flask be cleaned after use with biological samples?

For biological contaminants, autoclave at 121°C for 20 minutes, then rinse with distilled water followed by 70% ethanol. For stubborn residues, use a mild detergent solution with a soft brush.

5. Are there alternative flask sizes available in the same series?

The SF100 series includes variations like 250mL, 500mL, and 2L capacities, offering flexibility for different sample volumes while maintaining the same material and design specifications.
