The B3110-50 is the smallest-volume Erlenmeyer flask in the hybex B3110 family — 50 mL × 12 flasks per pack at $74 ($6.15 per flask). The B3110 family is the standard open-mouth Erlenmeyer flask line for cell culture, microbial culture, microbiology, and standard chemistry workflows at the bench-flask scale. Distinct from the B3220 capped Erlenmeyer family (Erlenmeyer flasks with integrated GL45 caps for sealed-container workflows).

Why an Erlenmeyer Flask — Bench-Flask Workflows
The Erlenmeyer flask geometry (conical body, narrow neck) is the workhorse format for bench-scale culture and chemistry workflows:
- Microbial / cell culture — narrow neck reduces evaporation while allowing aerobic exchange; the conical body provides good liquid coverage during shake-flask cultures
- Magnetic stirring — conical body geometry pairs well with magnetic stir plates
- Liquid mixing / titration — the swirl-mixing geometry is the lab standard for hand-mixed solutions
- Solution preparation — buffer / reagent prep at standard bench-flask volume
Pick the B3110-50 (50 mL) when:
- Workflow uses small-volume Erlenmeyer flasks for microbial culture starters, small-volume reactions, small-batch reagent prep
- 12-flask pack supports facility-scale small-flask workflows
- Open-mouth (uncapped) is appropriate — workflow doesn't require sealed-container storage between uses
Pick the B3220 capped Erlenmeyer family when sealed-container storage between uses is the workflow (GL45 cap for sealed-bottle storage in addition to flask use).
hybex B3110 Erlenmeyer Family — Pack-Size Selection
| SKU | Volume | Pack | Per-flask cost | List price |
| B3110-50 (this product) | 50 mL | 12/pk | $6.15 | $74 |
| B3110-125 | 125 mL | 12/pk | $7.51 | $90 |
| B3110-250 | 250 mL | 12/pk | $8.76 | $105 |
| B3110-500 | 500 mL | 6/pk | $12.25 | $74 |
| B3110-1000 | 1000 mL | 6/pk | $18.79 | $113 |
| B3110-2000 | 2000 mL | 1/each | $34.44 | $34 |
Pack quantity decreases with volume (12/pk for small volumes, 6/pk for medium, 1/each for the 2 L flask) — reflects the storage / shipping practicality of larger glassware.
Application Profile
Microbial culture starters — overnight starter cultures in 50 mL flasks for downstream scale-up.
Small-volume cell culture — small-batch suspension cultures, small-batch protein-expression starters.
Small-batch reagent / solution prep — 50 mL working solutions, small-batch buffer prep.
Magnetic-stir reactions — small-volume magnetic-stir reactions on stir plates.
Educational laboratory teaching — undergraduate / graduate microbiology / chemistry coursework where 50 mL Erlenmeyer flasks are the standard student-cohort format.
Multi-investigator shared-facility procurement — 12-flask pack supports facility-scale small-flask inventory.
Method-development workflows — protocol-development at small-volume Erlenmeyer scale.
Ordering & Configuration
Pair with appropriate stoppers / closures per workflow. B3110 family ships uncapped — for sealed-container workflows step to B3220 (capped Erlenmeyer family) or pair with separate stoppers.
Confirm autoclave compatibility. Erlenmeyer flasks are typically autoclave-safe (borosilicate glass standard) — confirm with Benchmark Scientific tech support if workflow includes specific autoclave-cycle protocols.
Plan for flask-replacement cycle. Glass flasks are durable but eventually accumulate scratches / chips; plan periodic replacement at facility scale.
Confirm at quote: flask material (typically borosilicate), autoclave compatibility, workflow scale, and lead time.
Warranty: Per Benchmark Scientific standard consumable terms.
