12×75 mm Test Tubes in Pakistan

12×75 mm Test Tubes (5 mL Culture / Sample Tubes) are versatile, high-clarity laboratory tubes engineered for clinical sample collection, blood grouping, serological testing, and routine laboratory centrifugations. Manufactured from premium, crystal-clear polystyrene (PS) for optical transparency or durable polypropylene (PP) for chemical and thermal resistance, these round-bottom tubes fit standard centrifuge rotors, test tube racks, and clinical analyzer units. Essential for pathology laboratories, blood banks, diagnostic centers, and university research facilities across Pakistan.

12×75 mm Test Tubes – Serology & Clinical Sample Tubes

12×75 mm Test Tubes provide a reliable, shatterproof, and cost-effective container solution for routine clinical diagnostics, immunological assays, and liquid handling workflows. Designed with a uniform wall thickness and a smooth round bottom, these tubes ensure consistent sedimentation and maximum thermal and mechanical stability during centrifugation. The ultra-smooth inner surface minimizes cell attachment and fluid retention, while the precision rim ensures a tight leak-proof fit with standard push caps or stopper closures. Available in both optical PS (ideal for visual inspection and spectrophotometry) and autoclavable PP (ideal for chemical resistance), these tubes meet international quality standards for medical and analytical testing across Pakistan.

Key Applications:

  • Blood Bank & Serological Testing: Standard tube size used for ABO/Rh blood grouping, cross-matching, Coombs testing, and antibody screening in blood banks.

  • Clinical Pathology & Immunoassay: Ideal for serology, radioimmunoassay (RIA), urine analysis, and sample storage in routine diagnostic laboratories.

  • Sample Preparation & Centrifugation: Used across research institutes for vortexing, serial dilutions, sample fraction collection, and low-to-medium speed centrifugation.

Specifications & Properties:

  • Product Name: 12×75 mm Test Tube / 5 mL Round-Bottom Tube

  • Dimensions: Outer diameter 12 mm x Length 75 mm

  • Nominal Volume: Approx. 5.0 mL capacity

  • Material Options: Crystal-clear Polystyrene (PS) for optical clarity OR high-durability Polypropylene (PP) for chemical/thermal resistance

  • Bottom Profile: Smooth round (U-bottom) profile for efficient pellet formation and sedimentation

  • Cap/Closure Options: Compatible with 12 mm push-plug caps, flanged caps, or rubber stoppers (sold separately or pre-capped)

  • Centrifugation Rating: Up to 3,000 x g (PS models) or up to 4,500 x g (PP models)

  • Thermal Tolerance: PS (-10°C to +70°C); PP (-80°C to +121°C, autoclavable)

  • Packaging Options: Bulk bags of 500 or 1,000 units

  • Storage Conditions: Store at ambient room temperature in a clean, dry location away from direct sun exposure and heat sources.

Safety & Handling:

  • Hazard Class: Non-hazardous labware consumable prior to use. Biohazardous once contaminated with blood, serum, or clinical fluids.

  • Handling & Usage: Inspect tubes for cracks prior to high-speed centrifugation. Ensure balanced tube loading in centrifuge rotors to prevent tube breakage and aerosol formation.

  • Disposal: Single-use disposable laboratory labware. Dispose of used clinical test tubes in designated biohazard waste containers or autoclave prior to disposal according to biomedical waste standards.
