    Frequently Asked Questions (FAQs)

    What material are these tubes and caps usually made from?
    Many 16 × 100 mm screw‑cap tubes are made from borosilicate or AR glass for chemical and thermal resistance, with polypropylene (PP) screw caps for a tight, durable seal.
    What is the typical capacity of a 16 × 100 mm screw‑cap tube?
    A 16 × 100 mm tube generally holds about 12–15 mL of sample, depending on wall thickness and design.
    Are these tubes leak‑proof and safe for transport?
    When properly tightened, screw‑cap tubes are designed to be highly leak‑resistant and are widely recommended for safe specimen transport and storage.
    Can screw‑cap test tubes be autoclaved?
    Glass screw‑cap culture tubes in borosilicate glass with suitable PP/PTFE caps are commonly described as autoclavable at around 121 °C; always follow the specific manufacturer’s instructions.
    Are these tubes reusable?

    Glass screw‑cap tubes are typically reusable after proper cleaning and sterilization, while many PP tubes are reusable for a limited number of cycles depending on your lab SOP.
