Corning Lab Funnel Borosilicate Glass 75mm

Description

Product Overview

The Corning Lab Short Stem Funnel is engineered for precise powder handling and liquid transfer in scientific settings. Constructed from Borosilicate glass code 7740, it provides superior chemical resistance, thermal shock durability, and clarity for easy inspection. Key dimensions include a 75 mm top inner diameter, 94 mm height, and a short 17 mm wide stem with a 17 mm outer diameter, delivering a compact profile without sacrificing flow capacity.

Usage

This funnel excels in laboratory environments where accurate powder dispensing and bottle filling are critical. Ideal for chemists, researchers, and quality‑control technicians, it facilitates the transfer of fine powders, reagents, and viscous liquids into containers of various sizes. Its short stem design minimizes dead volume, reducing waste and contamination risk during repetitive tasks.

FAQ

Can this funnel be used with corrosive chemicals?

Yes, the Borosilicate glass construction resists most acids, bases, and solvents commonly used in labs.

Is the funnel autoclavable?

The funnel can withstand standard autoclave cycles, making it suitable for sterile applications.

What is the maximum powder load it can handle?

Its 75 mm diameter allows generous powder capacity; however, for optimal flow, avoid overfilling beyond the stem height.

How do I clean the funnel after use?

Rinse with distilled water, then use a mild detergent or laboratory cleaning solution; the glass can also be placed in a dishwasher if compatible.

Does the short stem affect pouring speed?

The wide stem design actually promotes faster, more controlled pouring compared to narrow‑stem alternatives.
