FAQs

Q1: Why do I need a thickened glass flask for vacuum filtration?

A1: When you connect a vacuum pump to the flask, it pulls the air out, creating intense negative pressure inside. A standard, thin-walled Erlenmeyer flask cannot withstand this pressure and will violently implode, sending dangerous glass shards and chemicals everywhere. Our filtering flasks are heavily reinforced with extra-thick Borosilicate 3.3 glass to safely handle extreme suction forces.

Q2: Do I need filter paper to use the ceramic Buchner funnel?

A2: Yes. Unlike glass sand-core funnels, a ceramic Buchner funnel has a flat bottom with relatively large, laser-drilled holes. You must place a circular piece of qualitative or quantitative filter paper flat over these holes. Wet the paper slightly with your solvent to seal it before turning on the vacuum pump.

Q3: How do I ensure the rubber adapter creates a good seal?

A3: Place the tapered rubber adapter cone securely into the neck of the glass flask, then push the ceramic funnel down firmly into the rubber adapter. Once you turn on your laboratory vacuum pump, the negative suction pressure will naturally pull the funnel downwards, instantly creating a flawless airtight seal.

Q4: Will the provided vacuum hose collapse under high pressure?

A4: No. Standard silicone tubing will instantly suck flat (collapse) under strong vacuum pressure, cutting off the suction. The hose provided in this kit is manufactured from ultra-thick rubber with a massive 14mm outer diameter and an 8mm inner bore, ensuring it remains wide open and structurally rigid under intense negative pressure.
