FAQ
What comes in the GL-14 Vacuum Filtration & Solvent Purification Set?
The GL-14 Vacuum Filtration & Solvent Purification Set includes a borosilicate filtering flask (choose 500 mL, 1000 mL, 2000 mL, or 5000 mL), a 300 mL graduated funnel, an aluminum clamp, and a rubber stopper adapter.
What is the frit size and why does it matter?
The GL-14 Vacuum Filtration & Solvent Purification Set uses a 40 µm fritted glass disc, a versatile porosity for general solvent purification and routine lab filtrations.
Is the glassware chemical and heat resistant?
Yes. The GL-14 Vacuum Filtration & Solvent Purification Set is made from heavy-duty borosilicate glass, which is acid/alkali resistant and tolerant of high temperatures.
Which flask size should I choose?
Select the GL-14 Vacuum Filtration & Solvent Purification Set size that aligns with your SOP throughput—500 mL for small-batch prep, 1000–2000 mL for routine work, and 5000 mL for larger volumes.
