Product description

250mL glass dropping funnel with PTFE stopcock and angled stem for precise liquid addition without lubrication.

The Kimble KIMAX 250mL Dropping Funnel is a precision glassware instrument designed for controlled, dropwise addition of reagents in chemical and biotechnological laboratories. Featuring a chemically resistant PTFE stopcock, this funnel operates smoothly without lubrication, eliminating contamination risks important for molecular diagnostics and synthetic biology workflows.

Key technical features include:

  • 250mL capacity for moderate volume reagent additions
  • Angled glass stem enabling ease of single-drop delivery directly into reaction mixtures
  • Large white marking spot allowing clear, durable labeling for sample identification and traceability
  • PTFE stopcock resistant to corrosion and seizing, suitable for aggressive chemical and biochemical reagents
  • Ideal for bioprocessing applications, colorimetric assays, and biopharmaceutical production pipelines requiring precise reagent control
  • Widely used in biotechnology labs, organic synthesis, and analytical chemistry for liquid transfer and titration protocols

This dropping funnel supports critical workflows in gene editing experiments, live-cell assays, and molecular cloning workflows by ensuring exact reagent dosing and maintaining sample integrity through contamination-free valve operation.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
