USA Lab 20L ThermalShield 650°C Insulating Fabric for 20-22L Flasks

USA Lab ThermalShield – 20L

The USA Lab ThermalShield delivers superior protection and thermal performance at an affordable price. Designed to insulate your distillation setup, the shield keeps heat inside your flask where it’s needed most, improving efficiency and consistency.

Beyond thermal insulation, the shield also provides physical protection, helping safeguard your glassware against falling objects, thermal strain, and even potential implosions under high vacuum or fatigue stress.

Each shield is constructed with 96%+ SiO₂ glass fiber cloth and reinforced with two-sided liquid silicone cloth with glass fiber, offering premium insulation up to 650°C. The non-conductive materials create a safe and effective barrier around your flask.

The 20L ThermalShield is versatile, capable of accommodating 1, 2, or 3-neck 20–22L flasks, making it an excellent fit for a wide range of laboratory applications.
