Double-Ring Quartz Boat for Laboratory Furnaces

Заявка за решение за кварцово стъкло

Introduction

This double-ring quartz boat is designed for sample loading, calcination, ashing, material treatment and thermal processing in laboratory tube furnaces and muffle furnaces. The dual-ring structure provides stable handling, easy positioning, and reduced contact with heating zones, helping maintain consistent thermal behavior during experiments.

Key Features

Made from high-purity fused quartz with excellent thermal shock resistance
Smooth internal surface for uniform heating and easy sample removal
Double-ring structure for secure handling and stable placement
Flame-polished edges to reduce chipping and improve durability
Suitable for high-temperature laboratory applications and research workflows

Available Customization

TotalQuartzWorks supports full customization based on your application needs:

Length, outer diameter, and wall thickness
Single ring / double ring / reinforced ring designs
Round bottom, flat bottom, or customized trough geometry
Fine grinding or flame-polished finishing
Optional marking, numbering, or lot-tracking for laboratory management

Typical Applications

Powder calcination and heat treatment
Catalyst and material science experiments
Semiconductor and optics laboratory research
CVD, diffusion, and thermal processing
Ashing, oxidation, and controlled-atmosphere heating tasks
