Weighing Bottle, Low Form

The GISCOM Weighing Bottle, Low Form, is a precision-engineered glass container designed for accurate weighing, drying, and storing of laboratory samples. Its low-form design ensures stability on analytical balances, enabling precise and repeatable measurements. Manufactured from high-quality Borosilicate Glass 3.3, it offers excellent thermal and chemical resistance, making it an essential tool for routine and critical laboratory applications. This weighing bottle is widely used in pharma, chemical, academic, and QC laboratories where reliability, accuracy, and contamination-free handling are crucial.

Key Features

• Low-Form Design: Provides maximum stability on balance pans and reduces tipping risks.
• High-Precision Construction: Ensures consistent weight measurements with minimal sample loss.
• Borosilicate Glass 3.3: Exceptional resistance to heat, chemicals, and thermal shock.
• Perfectly Fitted Ground Stopper: Secure sealing for moisture-sensitive and volatile samples.
• Smooth Inner Surface: Prevents sample adherence and supports easy cleaning.
• Autoclavable & Reusable: Withstands repeated sterilization cycles without loss of clarity or performance.
• Leak-Resistant Storage: Ideal for storing hygroscopic materials and analytical samples.
• Durable & Long-Lasting: Designed to maintain structural integrity under rigorous laboratory use.

• Chemical Resistance: Excellent resistance to acids, alkalis, solvents, and organic chemicals. Non-porous, non-reactive surface to preserve sample integrity
• Mechanical Properties: High strength and durability

Technical Specifications

• Available Capacities: Typically available from 20 ml to 50 ml (as per the standard size table)
• Design: Low-form cylindrical body with ground-glass stopper.
• Dimensions: As per standard laboratory size charts (can be provided upon order).
• Tolerance: Manufactured within strict dimensional and volume tolerances for laboratory precision.
• Calibration: Not required; volumetric accuracy is not critical for weighing applications.
• Accessories Included: Matched ground-glass stopper, Optional PTFE stoppers (custom order)

Handling & Precautions

• Safe Use: Always ensure the bottle and stopper are clean and dry before weighing. Handle with care to avoid chipping of ground surfaces.
• Cleaning Instructions: Wash with laboratory-grade detergents; rinse with distilled water. Compatible with ultrasonic cleaners.
• Autoclaving: Fully autoclavable at standard sterilisation temperatures (121°C for 15–20 minutes). Avoid sudden temperature changes to prevent thermal shock.
• Do’s & Don’ts: Do preheat before placing in hot ovens. Do not expose to open flames or extreme thermal gradients. Do not force open tight stoppers; gently warm if necessary.
• Best Practices: Store in dry, clean cabinets. Inspect for cracks or abrasions before use.

Applications

• Pharmaceutical Industry: Moisture determination, sample drying, stability testing.
• Chemical Laboratories: Precise weighing of solids, reagents, and hygroscopic and volatile materials.
• Academic & Research Labs: Routine analytical experiments and gravimetric analysis.
• Biotechnology & Life Sciences: Handling sensitive compounds that require contamination-free storage.
• Quality Control & Quality Assurance: Accurate sample preparation and measurement workflows.

The low-form weighing bottle plays a critical role in ensuring accuracy, reproducibility, and traceability in daily laboratory operations.
