Splinter-Proof Titrating Burettes

Engineered specifically for demanding laboratory environments and mobile field testing, the glass burette tube features a heavy-duty, transparent plastic protective sheathing. This specialized coating significantly enhances mechanical strength against accidental impacts and contains sharp glass fragments and hazardous reagents in the event of internal breakage. Squeezing the flexible polyethylene base bottle automatically fills the column and sets the liquid level precisely to zero, eliminating manual pipetting steps and accelerating high-throughput workflows.

Key Functional Benefits:

• Shatter-Proof Safety Sheathing: Transparent plastic coating protects the inner Borosilicate Glass 3.3 tube from impacts and safely contains chemical spills and glass splinters if broken.
• Automatic Zero-Point Calibration: Integrated overflow tube automatically resets the meniscus to the zero line when pressure on the reservoir bottle is released.
• Dual-Action Precision Dosing: The ergonomic Burkle armature allows rapid fluid delivery via a spring-loaded push button, as well as drop-by-drop fine titration via an adjustable micro-screw.
• Calibrated to Ex (TD): Volumetric graduations are calibrated to deliver ("Ex"), ensuring reliable accuracy for quantitative chemical analyses.
• High-Contrast Readability: Printed blue graduation lines paired with an integrated Schellbach contrast stripe ensure instant, parallax-free meniscus readings.

Cleaning: Wash column assemblies using mild, non-abrasive laboratory detergents. Avoid harsh scouring tools that could scratch or weaken the outer plastic sheathing.
