Thermo Scientific Flask 1000 ml Baffled Base PETG Case of 6 Flasks

Thermo Scientific Nalgene 4113-1000 Erlenmeyer Flask – 1000 mL, PETG, Baffled Base

The Thermo Scientific Nalgene 4113-1000 is a single-use, 1000 mL Erlenmeyer flask engineered for the efficient preparation, mixing, and storage of suspension cell cultures and biological media. Molded from crystal-clear, break-resistant Polyethylene Terephthalate Glycol (PETG), this disposable flask serves as a robust alternative to fragile glass laboratory ware. A key feature of this specific model is its baffled bottom geometry, which dramatically increases hydrodynamic agitation and gas exchange when placed on an orbital shaker. Supplied with a solid, non-vented high-density polyethylene (HDPE) screw cap, the flask is provided pre-sterilized and ready to use, completely eliminating the costly downtime and contamination risks associated with washing and autoclaving reusable glassware.

Technical Performance and Design

• Baffled Bottom Geometry: The molded internal baffles disrupt laminar fluid flow during orbital shaking. This converts a simple swirl into a turbulent mixing action, driving oxygen deep into the culture media and preventing cells from settling.

• Crystal-Clear PETG Construction: The premium PETG resin provides glass-like optical clarity for easy visual inspection of culture turbidity, while remaining highly shatter-resistant to ensure technician safety.

• Solid Sealing Cap: Equipped with a solid, non-vented screw closure. This creates a secure, leak-proof seal ideal for anaerobic cultures, sealed mixing applications, or the long-term cold storage of prepared biological buffers.

• Molded Graduations: Features prominent, molded-in volumetric graduations that will not rub off or fade, allowing researchers to quickly and accurately assess fluid levels without requiring secondary measuring vessels.

Key Benefits & Applications

• Suspension Cell Culture: The rigorous mixing action created by the baffles makes it an essential vessel for high-density bacterial, yeast, or mammalian suspension cultures that require elevated dissolved oxygen levels.

• Time and Cost Efficiency: Discarding the flask after a single use completely eliminates the labor, water, and energy costs associated with the rigorous cleaning and autoclaving cycles of traditional glass Erlenmeyer flasks.

• Cross-Contamination Prevention: Arriving sterile and strictly single-use guarantees a pristine environment for each new culture, avoiding the residual detergent or protein carryover that plagues poorly washed reusable vessels.

• Safe Waste Disposal: The PETG material safely collapses under the heat and pressure of a standard autoclave cycle, significantly reducing the volume of biohazardous waste generated by the laboratory.
