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.
