About this product

Screw Caps

Description:

Screw caps are threaded closures designed to seal containers such as bottles, vials, tubes, or jars. They are used across labs, manufacturing, and storage environments to ensure secure, leak-proof containment of liquids, powders, or samples. They come in various materials, liner types, and thread standards (e.g., GL45, GL18).


📐 Specifications:

  • Materials:

    • Polypropylene (PP) – autoclavable, chemical-resistant, lightweight

    • Polyethylene (PE) – economical and flexible, not always autoclavable

    • Phenolic resin – high temperature and chemical resistance

    • Metal (aluminum/stainless) – for industrial/chemical use

  • Sizes (thread types):

    • Standard thread types: GL25, GL32, GL45, GL80, or custom

    • Diameter ranges: 13 mm to 120+ mm

  • Liner Options:

    • PTFE/Silicone – for aggressive chemicals or air-tight sealing

    • Polyethylene Foam – general-purpose seal

    • Rubber or Teflon-faced rubber – for analytical uses

  • Colors: Often color-coded for identification

  • Autoclavable: PP and some others, depending on material


🧪 Uses:

  • Sealing laboratory bottles, tubes, vials

  • Chemical storage in reagent or sample bottles

  • Transporting liquids safely without leaks

  • Preventing contamination of sterile samples or reagents

  • Color-coded systems for reagent or sample differentiation


Features

  • Threaded Design: Ensures secure, reusable seal

  • Leak-Proof & Airtight: With compatible liners or gaskets

  • Chemically Resistant: Available materials handle acids, solvents, bases

  • Reusable: Most lab-grade screw caps are durable and autoclavable

  • Variety of Sizes: Fits vials, bottles, and tubes of many volumes

  • Optional Vented Caps: For sterile filtration or gas exchange

  • Color-Coded Options: Simplifies identification and organization

  • Wide-Mouth or Narrow Options: For easy pouring or precise control
