The F4060-B is the 125 mL polycarbonate baffled-bottom sterile Erlenmeyer flask with vented screw cap — sold at $268 / case of 24 ($11.17/flask). NEW PRODUCT FAMILY: F40xx Erlenmeyer flask line — 4 volumes (125 / 250 / 500 / 1000 mL) × 2 materials (Polycarbonate baffled / PETG flat-bottom). Individually wrapped sterile for direct-to-cell-culture workflow.
Author confidence note (MEDIUM) — class flag: Universe labels this SKU capital but case-pack sterile single-use flasks are functionally consumable. Flagging FQ-class for tech-support clarification at brand closeout.

Why Polycarbonate Baffled vs PETG Flat-Bottom
The F40xx family is offered in two material / bottom combinations at each volume — each suited to different cell-culture / shaking-flask workflow needs:
| Feature | F40xx-B (Polycarbonate Baffled, this product) | F40xx-F (PETG Flat-Bottom) |
| Material | Polycarbonate | PETG |
| Bottom | Baffled | Flat |
| Mixing efficiency | Higher (baffles induce turbulence) | Standard |
| Aeration / O₂ transfer | Higher (enhanced gas-liquid interface) | Standard |
| Optical clarity | Clear | Clear |
| Autoclavability | Yes (polycarbonate) | Limited (PETG is single-use) |
| Cost per flask | Higher (this product) | Lower |
Pick the F4060-B (polycarbonate baffled) when:
- Mammalian / microbial suspension culture with shaking workflow — baffles enhance mixing and oxygen transfer
- High-density cell culture where O₂ transfer is rate-limiting
- Method-development workflows that benefit from controlled turbulence
- Polycarbonate durability allows multiple uses if reused (autoclave between cycles)
Pick F4060-F (PETG flat-bottom) when:
- Standard cell-culture flask workflow without mixing-enhancement need
- Static culture or low-shaking workflows
- Single-use disposable workflow — PETG is cost-optimized for one-time use
- $28 per case savings ($240 vs $268)
