Custom Quartz Combustion Boats

Small open quartz troughs for sample combustion, ashing, or thermal treatment inside a furnace tube — sized to your sample volume and furnace tube ID.

Capacity isn't a spec on its own — it follows directly from length, width, and depth, so send those three dimensions rather than a target volume alone. The boat also has to fit inside your furnace tube ID with clearance to load and unload, so confirm tube ID alongside boat width.

Wall, Bottom and End Geometry

Wall and bottom thickness are chosen for thermal shock resistance and handling durability, not for capacity — a boat that's repeatedly heated and cooled needs enough wall thickness to avoid cracking, which is more of a factor at larger sizes. Ends are typically open (rectangular trough) or slightly upturned to keep sample material from spilling during handling.

Quartz Combustion Boats Size / Capacity / Joint Standard

Boat length and width are usually constrained by your furnace tube's inside diameter — the boat has to pass through the tube opening and sit within the heated zone. Send your furnace tube ID and heated-zone length alongside your target sample capacity so we can confirm a boat that fits both.
