About this item
Sterile Storage & Culture Incubation
Xin Tester Threaded Erlenmeyer Flask (50mL – 2000mL)
Standard narrow-neck flasks require cotton plugs or aluminum foil wraps, which risk contamination during vigorous shaking and media transport. The Xin Tester threaded Erlenmeyer flask features a molded GL-standard screw neck fitted with a liner-sealed screw cap. Fabricated from Type I Class A 3.3 borosilicate glass, it ensures zero alkali leaching and high thermal shock resistance. Explore our complete selections in the Lab Glassware catalog.
Leak-Proof GL Thread Geometry
Heavy-pitch glass threads provide effortless cap tightening and loosening. The inner cap PTFE sealing disk creates an airtight barrier against organic solvent vapor escape and microbial contamination.
Conical Vessel Mixing Dynamics
The wide conical base and tapered neck promote smooth vortex fluid mechanics on orbital shakers without spilling, while offering ideal geometry for culturing bacteria, fungi, and suspension cells.
Capacity Options & Use Advice
Available in 50mL, 100mL, 150mL, 250mL, 500mL, 1000mL, and 2000mL. Always loosen screw caps slightly before autoclaving to allow internal steam pressure relief.

FAQs
Q1: What is the main advantage of a screw cap Erlenmeyer flask over a standard one?
A1: The threaded screw cap provides a highly secure, leak-proof seal. Unlike open-mouth or rubber-stoppered flasks, it allows you to aggressively shake cultures or store volatile chemicals long-term without any risk of spilling or evaporation.
Q2: Are the cap and the pouring ring safe for autoclave sterilization?
A2: Yes. Both the blue screw cap and the clear anti-drip pouring ring are manufactured from high-quality Polypropylene (PP). They are highly heat-resistant up to 140°C, making them perfectly safe for standard 121°C or 134°C laboratory autoclave cycles.
Q3: When should I choose the amber glass option?
A3: Amber glass is specifically designed to block ultraviolet (UV) light. You should choose the amber flask if you are storing light-sensitive chemical reagents, pharmaceutical compounds, or biological samples that undergo photochemical degradation when exposed to normal room lighting.
Q4: Can I heat this flask directly on a bunsen burner?
A4: No. You should never apply a direct open flame to the flat bottom of any Erlenmeyer flask, as localized heat causes uneven thermal expansion and cracking. You must always place a ceramic-centered wire gauze between the flame and the glass to distribute the heat evenly.
