Laboratory funnel Manufacturer, Suppliers and Exporter in India
Lab Glassware Manufacturer is leading Laboratory funnel Manufacturer,and supplier and Exporter in Amabla India
Filtration, liquid-liquid extraction and controlled reagent addition are the main tasks served by the Laboratory Funnel range from Lab Glassware Manufacturer. Plain filter funnels suit gravity filtration, while Buchner and fritted-disc funnels work with a filter flask and pump for vacuum filtration. Separating funnels in pear, cylindrical or Squibb shapes handle solvent separation, and dropping funnels, some pressure-equalising, add reagent dropwise. A PTFE key stopcock needs less maintenance than solid glass, and powder or thistle funnels help with transfers into narrow necks.

What Sits Inside the Laboratory Funnel Category
All individual funnel listings are catalogued under the Funnel subcategory. The table below groups them by the job a buyer is actually trying to do, rather than by product code.
| Funnel type | Distinguishing feature | Typical buyer |
|---|---|---|
| Filter / analytical funnel | Plain or polypropylene funnel for gravity filtration | Routine filtration in teaching and QC labs |
| Buchner / fritted-disc funnel | Flat perforated or sintered-glass disc for vacuum filtration | Labs running vacuum filtration with a filter flask and pump |
| Separating funnel | Pear, cylindrical or Squibb/Gilson shape with glass or PTFE stopcock | Liquid–liquid extraction and solvent separation work |
| Dropping funnel | Cylindrical or pear shape, needle-valve, PTFE or solid-glass stopcock, some pressure-equalising | Controlled, dropwise addition of a reagent during a reaction |
| Powder / cone / thistle funnel | Wide stem or long stem for solids or narrow-neck pouring | Powder transfer and general pouring into narrow-necked vessels |
| Funnel holders & vacuum filtration kits | Stands, holders and complete filtration set-ups | Fitting out a complete filtration station |
Choosing Between Laboratory Funnel Options
Start from the task rather than the shape: gravity filtration of a routine sample calls for a plain or fritted filter funnel, while vacuum filtration of a precipitate needs a Buchner or fritted-disc funnel used with a filter flask and pump. Liquid–liquid extraction calls for a separating funnel, where the stopcock choice (PTFE key, solid glass or PTFE needle-valve) follows the same reasoning as for burettes — PTFE needs less maintenance and resists most solvents, while a pressure-equalising side-arm is worth adding for closed-system, air-sensitive dropping.
Frequently Asked Questions
What is the difference between a filter funnel and a Buchner funnel?
A plain filter funnel relies on gravity and is used with folded filter paper for routine filtration. A Buchner or fritted-disc funnel has a flat perforated base and is used with a filter flask under vacuum, which filters much faster and suits finer precipitates.
Which stopcock should a separating or dropping funnel use?
PTFE key stopcocks are a practical default because they need little maintenance and resist most common solvents and reagents; a solid-glass stopcock is a lower-cost option for light use, and a PTFE needle-valve suits fine, dropwise control near the end of an addition.
What is a pressure-equalising dropping funnel used for?
A pressure-equalising funnel has a side arm connecting the headspace above the liquid to the receiving flask, which keeps the addition rate steady in a closed or inert-atmosphere set-up where a plain vented funnel is not suitable.
