Test Tube With Screw Cap, PP

GISCOM’s Test Tube With Screw Cap (PP) is a durable, leak-proof laboratory tube designed for reliable sample handling, storage, mixing, and centrifugation tasks. Manufactured from high-quality polypropylene, it ensures excellent chemical resistance and secure sealing for sensitive biological, chemical, and clinical samples. These tubes are widely used in research labs, diagnostics, microbiology, and quality-control workflows where dependable sample integrity is essential.

Key Features

• Leak-proof screw cap ensures secure closure and prevents sample evaporation or contamination.
• High-clarity polypropylene body for easy sample visibility.
• Chemically resistant to most acids, bases, and organic solvents.
• Strong mechanical durability, suitable for routine laboratory use.
• Uniform wall thickness for consistent performance.
• Non-cytotoxic and biologically safe for sensitive applications.
• Lightweight and shatter-resistant alternative to glass test tubes.
• Compatible with standard laboratory racks, mixers, and centrifuges (within defined limits).

Material Specifications

Material: Premium Polypropylene (PP)

Properties:

• High chemical resistance
• Excellent thermal stability (typically up to 121°C for autoclaving)
• Impact-resistant and non-breakable
• Low protein binding

Compliance: Manufactured according to global laboratory plasticware standards (ISO-compliant manufacturing environment)

Technical Specifications

• Available Sizes: As per the standard size table
• Dimensions: Precision-moulded inner and outer diameters for smooth handling.
• Closure Type: Screw cap (PP), ribbed for a firm grip.
• Tolerance/Accuracy: Uniform dimensions, controlled through high-precision moulds.
• Calibration: Transparent body for easy visual volume estimation (non-graduated unless specified).
• Accessories: Screw caps are included with every tube; coloured cap options are available on request.

Handling & Precautions

• Autoclavable at 121°C (ensure caps are loosened before autoclaving).
• Avoid exposure to temperatures above recommended PP limits to prevent deformation.
• Suitable for mild centrifugation (verify model-specific RPM limits).
• Do not use with strong oxidising agents that may degrade PP.
• Clean using mild laboratory detergents; avoid abrasive cleaners.
• Ensure caps are tightened securely to maintain sample integrity.
• Store in a clean, dry environment away from direct heat.

Applications

• Clinical & Diagnostic Labs: Blood, serum, and sample preparation.
• Microbiology & Bacteriology: Culture preparation, organism transport, inoculation.
• Pharmaceutical & Biotech: Sample storage, QC/QA workflows, stability testing.
• Chemical Laboratories: Reaction set-ups, reagent handling, routine analysis.
• Academic & Research Institutions: Teaching, training, and experimental work.

These tubes support daily workflows in R&D labs, production facilities, and controlled environments where reliable sample management is essential.
