13x100 mm Test Tubes in Pakistan

13×100 mm Test Tubes in Pakistan

13×100 mm Test Tubes (7 mL / 8 mL Sample & Culture Tubes) are high-clarity laboratory tubes engineered for clinical sample collection, serological testing, blood fractioning, and routine laboratory centrifugations. Manufactured from premium, optical-grade polystyrene (PS) for visual transparency or chemical-resistant polypropylene (PP) for thermal stability, these round-bottom tubes fit standard centrifuge rotors, test tube racks, and automated analyzer racks. Essential for pathology laboratories, diagnostic centers, blood banks, and educational institutions across Pakistan.

13×100 mm Test Tubes – Clinical Diagnostic & Sample Tubes

13×100 mm Test Tubes provide a reliable, shatterproof, and cost-effective container solution for routine clinical chemistry, serological assays, and general 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 seal 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 Collection & Serological Testing: Standard tube size used for blood sample processing, serum separation, cross-matching, and routine serology in clinical labs.
Pathology & Immunoassay Workflows: Ideal for sample aliquoting, urine analysis, viral transport media, and assay incubation in diagnostic centers.
General Laboratory Centrifugation & Prep: Used across academic and industrial research labs for sample mixing, serial dilutions, and low-to-medium speed centrifugation.

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.
