Lab Safety Conical Flask 250 mL Pack

The Lab Safety Supply Inc 5YHR2 is a clear glass Erlenmeyer flask with a ground mouth and canted neck. It comes in a pack of 12 units, each offering a 250 mL capacity with 8.4 oz equivalent. The transparent body features printed graduations from 50 to 250 mL in 50 mL subdivisions for easy volume reading.

Ground Mouth Compatibility

The single specification that determines fit is the ground mouth neck style, which accepts standard glass stoppers for a secure seal. This non-sterile flask is autoclavable, allowing repeated heat sterilisation without damage to the glass body. Buyers needing a threaded or snap-cap closure will find this neck style incompatible with those sealing methods.

Laboratory Build Integration

Each flask stands 5.5 in tall and integrates into general lab workflows requiring mixing, heating, or temporary storage of solutions. The clear glass construction frees users from concerns about chemical reactivity common with plastic alternatives. The pack of 12 supports high-throughput routines while the absence of included closures means stoppers must be sourced separately to complete the setup.

Questions about this item

What does the 250 mL capacity mean when I am measuring liquids in the flask?

The flask holds up to 250 mL total, with graduations from 50 mL to 250 mL in 50 mL steps so you can read approximate volumes directly on the glass.

How does the ground mouth affect what stoppers or closures I can use?

The ground glass neck accepts standard taper stoppers or joints for a tight seal; no closure is included, so you choose the stopper size that matches the taper.

Will the 5.5 in height fit on my shelf or in my autoclave?

At 5.5 inches tall, the clear glass Erlenmeyer fits most bench shelves and is autoclavable for steam sterilisation.
