Fabricated from high-durability, chemically resistant fiberglass yarn and woven textile fabric, this hemispherical mantle cradles the lower half of single-neck and multi-neck glass vessels. This lower-body coverage delivers efficient thermal transfer up to internal operating temperatures of 450 C while maintaining complete visual clarity of the upper flask neck, fluid reflux lines, and condensation levels. Powered at 115V AC (180 Watts), it features a built-in 2-wire lead with a twist-lock connector designed to integrate with external variable voltage or proportioning temperature controllers, preventing localized hot spots and thermal shock risks on glass walls.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance and Structural Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSoft Flexible Fabric Construction:\u003c\/b\u003e Woven from high-purity fiberglass yarn, allowing the mantle body to conform closely to standard 250 mL round-bottom glass contours.
