Precision mixing, heating, and titration are vital for achieving accurate analytical outcomes. Professional laboratory flasks are engineered from high-grade borosilicate glass to provide exceptional thermal shock resistance and chemical durability. As a core component of our vessels range within general laboratory consumables, these flasks are foundational for daily research tasks and complex chemical reactions.
Why Choose Professional Laboratory Flasks and Accessories?
Our curated collection of reaction vessels and stabilizing tools is designed for mechanical strength and user safety:
- DWK Duran Super Duty Flasks: We stock DWK Duran Super Duty Erlenmeyer Flasks in both narrow and wide neck configurations (25 mL to 2000 mL), featuring reinforced rims to significantly reduce the risk of breakage.
- Secure Stabilization: Utilize Heathrow Scientific Lab Ring Leads (42 mm to 66 mm C-Shape) to weight down flasks in water baths, preventing them from floating or tipping during heating.
- Advanced Material Science: Find flasks crafted from authentic Duran glass, recognized for its superior resistance to corrosive reagents and high-temperature applications.
- Optimized Neck Designs: Explore narrow neck flasks for minimizing evaporation or wide neck options for easier filling and cleaning in routine lab procedures.

Frequently Asked Questions
1. What makes a DWK Duran "Super Duty" flask different from standard flasks?
DWK Duran Super Duty Erlenmeyer flasks feature a modified rim design that provides increased mechanical strength, significantly reducing the risk of chipping or cracking during heavy daily use.
2. Why use a C-shaped ring lead with laboratory flasks?
The C-shaped design by Heathrow Scientific allows the weights to be easily slipped around the neck of a flask, even if there are already tubing connections in place, ensuring stability in water baths.
3. Are these Erlenmeyer flasks suitable for heating?
Yes, all DWK Duran and Bohemia Cristal flasks are manufactured from borosilicate glass, which is specifically designed to withstand direct heating and rapid thermal changes.
4. When should I choose a wide neck flask over a narrow neck?
Wide neck flasks are ideal for procedures involving high-viscosity liquids or for tasks that require the frequent addition of solids, as they provide easier access for spoons and cleaning brushes.
