Burette, TPX

The GISCOM Burette, TPX is a high-precision volumetric instrument designed for titration and quantitative liquid dispensing in analytical laboratories. Manufactured from premium TPX/PMP for exceptional clarity, it ensures accurate and reliable measurements required in routine and advanced analytical workflows. Its leak-proof stopcock system and individually calibrated scale make it essential for chemical analysis, quality control, and research applications.

 Key Features

• Crystal-Clear TPX/PMP Body for excellent visibility of liquid meniscus.
• Leak-Proof Stopcock equipped with a self-lubricating PTFE plug for smooth, controlled flow.
• Individually calibrated to deliver maximum measurement accuracy.
• High Chemical Resistance to dilute acids, alkalis, and most laboratory reagents.
• Wide pH Compatibility (1–14) supporting diverse titration applications.
• Safe & Shatter-Resistant alternative to traditional glass burettes.
• Durable Acrylic Construction unaffected by common mineral acids and bases (except HF and ammonium hydroxide).
• Lightweight and Easy Handling, ideal for high-throughput laboratory environments.

 Material Specifications

• Material: TPX® / Polymethylpentene (PMP) or equivalent acrylic-grade laboratory plastic.

Properties:

• High transparency for precise meniscus reading
• Excellent resistance to a wide range of laboratory chemicals
• Low moisture absorption and dimensional stability
• Heat resistance typically up to ~170°C (dry); safe wet heat below standard autoclave levels depending on protocol

Compliance: Manufactured using internationally accepted laboratory volumetric standards (ISO-style accuracy).

Technical Specifications

• Available Sizes: Common burette capacities include 25 ml and 50 ml (or as per order specification).
• Graduations: Fine, clearly printed, permanent markings for precise titration readings.
• Accuracy Class: Conforms to standard burette tolerance limits suitable for analytical use.
• Calibration: Individually calibrated for accuracy; supplied “To Deliver” (TD).
• Stopcock Assembly: Leakproof acrylic body with PTFE plug ensuring smooth and drip-free flow control.
• Chemical Compatibility: Suitable for up to 5% w/w acid solutions or 30% w/w bases.
• Accessories Included: Complete burette with fitted stopcock unit, ready for use.

Handling & Precautions

• Safe Use: Operate the stopcock gently to maintain calibration and prevent mechanical wear.
• Cleaning: Rinse with distilled water after each use; use mild detergents when required. Avoid abrasive cleaning to protect clarity and graduations.
• Heating & Autoclaving: Avoid high-temperature sterilization unless strictly within TPX safe limits; prolonged autoclaving may cause material stress.

Do’s:

• Store vertically to prevent stopcock distortion.
• Ensure stopcock lubrication remains intact.

Don’ts:

• Do not use with hydrofluoric acid or concentrated ammonium hydroxide.
• Do not expose to open flame or extreme heat sources.

Appropriate handling ensures long service life and preserves volumetric accuracy.

Applications

• Academic & Research Laboratories – titration, chemical analysis, solution standardization.
• Pharmaceutical QC/QA Labs – precise volumetric testing and assay preparation.
• Chemical & Petrochemical Industries – routine titrimetric evaluations.
• Biotechnology & Life Sciences – buffer preparation and controlled analytical workflows.
• Environmental & Water Testing Labs – alkalinity, hardness, and various field analyses.

Indispensable for any laboratory requiring consistent titration accuracy and durable plastic burettes.
