Applications and Experiments for the 250 ml Separating Funnel
With twice the volume of the 125 ml model, this separator handles a full demonstration batch or a solvent extraction that needs repeated washing. It is filled through a Glass Funnel, shaken, then clamped on a Laboratory Retort Stand while the layers settle and the lower one runs off through the tap.
- Class 9 science: a teacher demonstration of oil and water separating into layers.
- Class 12 chemistry: washing and separating an organic product from an aqueous layer.
- B.Sc. organic chemistry: solvent extraction with repeated portions of solvent.
- B.Pharm practicals: extraction steps in preparing and purifying compounds.
Vent the funnel after each shake by inverting it and opening the tap, keep solvents away from flames, and let students work with it only under supervision.
Standard Scope of Supply
Each unit is supplied as one 250 ml glass separator complete with its tap and frosted stopper. The retort stand and the ring or clamp needed to support it are separate items that can join the same quotation, along with a receiving beaker or flask.
Packing, MOQ and Lead Time
From a single demonstration funnel to a full practical batch, Science Lab Supplies quotes the quantity you name, with packing, delivery time and price set out clearly. Stands, beakers and the smaller separator can be added from the same laboratory glassware supplier in India.
Holding an Importer-Exporter Code as a registered exporter, Science Lab Supplies is able to ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Prices for the 250 ml separator are given on request: add it to the enquiry cart, send a short note via the contact page, or, for a tender, start with the lab tender page.
Frequently Asked Questions
How is this model different from the 125 ml separator?
Both have a spherical glass body with a tap and frosted stopper; this one holds 250 ml, so it suits demonstrations and extractions that need more liquid than the 125 ml size allows.
Why vent a separating funnel?
Shaking a volatile solvent builds pressure inside. Inverting the funnel and briefly opening the tap releases it so that the stopper does not blow out.
Who supplies the 250 ml Separating Funnel (Separator)?
Science Lab Supplies, operating out of Ambala, India, quotes this separator to schools, colleges, training institutes and distributors, and prices it for tender contractors on request.
What can collect the lower layer?
Any clean vessel placed under the stem, for example the Chemical Glasses (Beaker) 250ml, which matches the separator’s capacity. Close the tap as soon as the boundary between layers reaches it.
