16x150 mm Test Tubes with Rim – Heavy-Duty Laboratory Culture & Reaction Tubes 16x150 mm Test Tubes with Rim deliver exceptional structural strength, thermal resilience, and versatility for demanding laboratory procedures. Manufactured from low-expansion borosilicate glass (or high-grade autoclavable polypropylene), these tubes withstand rapid temperature fluctuations, direct flame heating, and aggressive chemical reagents without cracking or leaching. The flared, fire-polished rim provides a secure grip for handling with tube holders, prevents accidental slippage, and facilitates easy sealing with cotton plugs, rubber stoppers, or plastic caps. Designed with uniform wall thickness and a smooth round bottom, they ensure optimal heat distribution and reliable sedimentation during centrifugation across analytical labs throughout Pakistan. Key Applications: Microbiological Culturing & Fermentation: Ideal for growing bacterial strains, yeast cultures, and biological broths in bacteriology and biotechnology labs. Qualitative Chemical Analysis & Heating: Used for heating solutions, conducting precipitation reactions, and performing flame tests over Bunsen burners. Sample Collection & Centrifugation: Suited for bulk sample aliquoting, serological testing, and medium-speed laboratory centrifugation. Specifications & Properties: Product Name: 16x150 mm Test Tube with Rim / Rimmed Culture Tube Dimensions: Outer diameter 16 mm x Length 150 mm Nominal Capacity: Approx. 25 mL to 30 mL volume Material Options: Low-expansion Borosilicate Glass (heat-resistant) OR autoclavable Polypropylene (PP) Rim Design: Flared, reinforced fire-polished rim for secure gripping and cotton plugging Bottom Profile: Smooth round (U-bottom) profile for uniform heating and centrifugation Thermal Resistance: Borosilicate glass withstands continuous temperatures up to 500°C and thermal shock up to 100°C ΔT Chemical Resistance: Highly inert against strong mineral acids, organic solvents, salts, and biological solutions Packaging Options: Bulk packs of 100 units in protective corrugated boxes with divider inserts Storage Conditions: Store upright in a clean, dry location protected from mechanical shock and heavy impacts. Safety & Handling: Hazard Class: Non-hazardous consumable prior to use. Glass tubes present a thermal burn hazard when heated and a laceration hazard if broken. Handling & Usage: Always heat glass test tubes uniformly using a wire gauze or water bath, pointing the open end away from personnel. Use proper test tube holders or tongs when heating over flames. Disposal: Dispose of broken or chemically contaminated glass tubes in rigid sharps containers or specialized glass waste bins according to laboratory safety protocols.

Description

12×100 mm Test Tubes – Serology & Clinical Sample Tubes

12×100 mm Test Tubes provide a reliable, shatterproof, and cost-effective container solution for routine clinical chemistry, serological assays, and specialized sample handling. 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:

  • Clinical Chemistry & Serological Testing: Standard elongated tube size used for blood sample processing, serum separation, cross-matching, and routine serology in clinical labs.

  • Pathology & Diagnostic Workflows: Ideal for sample aliquoting, urine analysis, viral transport media, and assay incubation in diagnostic centers.

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

Specifications & Properties:

  • Product Name: 12×100 mm Test Tube / 6 mL Round-Bottom Tube

  • Dimensions: Outer diameter 12 mm x Length 100 mm

  • Nominal Volume: Approx. 6.0 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 plug 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)

  • Sterility Options: Available in bulk non-sterile packs or individually wrapped sterile packs

  • 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 biological 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.
