Laboratory funnel Manufacturer, Suppliers and Exporter in India

Lab Glassware Manufacturer is leading Laboratory funnel Manufacturer,and supplier and Exporter in Amabla India

Lab Glassware Manufacturer designs, produces and exports laboratory funnels from its manufacturing base in Ambala, Haryana, in continuous operation since 1982. This category covers liquid-transfer, powder-transfer, filtration, separating, dropping, pressure-equalising and vacuum-filtration glassware supplied to school and college science departments, university and research laboratories, and industrial QC labs in India and to export buyers that have recently included institutions in Sri Lanka, Bangladesh and Nepal — part of a wider base of enquiries from across South Asia.

Quick answer: A laboratory funnel guides liquids, powders or filtered residues into a narrow-necked vessel, and the term covers a wide family of designs — filter funnels, Buchner and fritted-disc funnels for vacuum filtration, separating funnels for liquid–liquid extraction, dropping funnels for controlled reagent addition, powder and thistle funnels, and the holders and vacuum filtration kits used alongside them. The Funnel range under this category lists the individual designs and stopcock options available.

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

Standards Behind the Range

Funnels in this range are manufactured to align with the specifications that exist specifically for this product family — ISO 4798:1997 (Laboratory glassware – Filter funnels), ISO 4800:1998 (Laboratory glassware – Separating funnels and dropping funnels) and ASTM E1095 (Standard Specification for Common Laboratory Glass Funnels), with polypropylene funnels referencing ISO 7057 (Plastics laboratory ware – Filter funnels).

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.

For bulk, tender or export enquiries, send the funnel type, stem length, stopcock preference, disc porosity (for fritted funnels) and destination country in one enquiry so a single quotation can cover a complete filtration or extraction set-up rather than one line at a time.

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.

Can Lab Glassware Manufacturer supply funnels against school or government tenders?
Yes. Funnels and filtration sets can be supplied against school, college and government tenders, including Ministry of Education-linked programmes, as bulk or class-set orders. Share the tender specification, required type and quantity through Contact Us or the Tenders page.

Do you export Laboratory Funnel products outside India?
Yes, funnels and filtration accessories are exported to institutional and distributor buyers outside India, with recent enquiries from Sri Lanka, Bangladesh and Nepal among other South Asian markets. Export orders should confirm destination country, required documentation and protective packing for the glassware at enquiry stage.
