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

16×150 mm Test Tubes without Rim – Precision Rimless Laboratory Tubes

16×150 mm Test Tubes without Rim deliver a streamlined, snag-free profile designed for modern laboratory workflows where automated capping, deep-well incubation, and compact storage racks are utilized. By eliminating the traditional flared lip, these rimless tubes allow stoppers, seals, and automated sample handlers to slide on and off effortlessly without catching. Manufactured from thermal-shock-resistant borosilicate glass or optical-grade plastic, they provide excellent chemical inertness against acids, bases, and biological reagents while ensuring clear visual inspection. Their uniform wall thickness guarantees balanced performance during centrifugation across diagnostic and analytical centers throughout Pakistan.

Key Applications:

  • Automated Clinical Analyzers: Ideal for high-throughput clinical chemistry platforms and automated sample handling systems that require rimless tube geometry.

  • Centrifugation & Sample Aliquoting: Suited for medium-speed centrifugation, blood fractioning, and general liquid sample storage.

  • Chemical Testing & Heating: Used in academic and industrial labs for qualitative reactions, reagent mixing, and controlled heating applications.

Specifications & Properties:

  • Product Name: 16×150 mm Test Tube without Rim / Rimless 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 optical-grade Polystyrene (PS) / Polypropylene (PP)

  • Rim Design: Plain, flat-cut rimless top to facilitate automated capping and plug sealing

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

  • Thermal Tolerance: Glass versions withstand temperatures up to 500°C and thermal shock; plastic versions rated per polymer spec

  • Chemical Resistance: High resistance to aggressive chemical solutions, aqueous reagents, and biological fluids

  • Packaging Options: Bulk packs of 100 or 500 units in protective cartons

  • Storage Conditions: Store upright in a clean, dry location protected from mechanical impact and moisture.

Safety & Handling:

  • Hazard Class: Non-hazardous labware consumable prior to use. Glass tubes present thermal burn risks when heated and laceration risks if fractured.

  • Handling & Usage: Use appropriate tube holders or racks when transferring or heating samples. Ensure balanced rotor placement during centrifugation.

  • Disposal: Dispose of broken or biohazard-contaminated glass tubes in rigid sharps containers or specialized glass waste bins in accordance with laboratory safety standards.
