How do I know which rubber stopper size fits my test tube or flask?

Rubber stoppers are numbered by a graduated size system, and each number maps to a top and bottom diameter in millimetres. Measure the inner mouth diameter of your tube, flask, or bottle in mm and pick the stopper whose bottom (smaller) diameter is slightly larger so it wedges to form a seal. This Enjoyist set includes detailed dimensions for each size, from #000 to #7, to help you select the correct fit for your glassware.

Can these Enjoyist rubber stoppers be autoclaved and reused?

The suitability of these Enjoyist rubber stoppers for autoclaving is not specified. Natural rubber, the material used, may degrade or harden at high temperatures typically used in autoclaving. For applications requiring repeated steam sterilization, it is advisable to consult the manufacturer's specifications or consider stoppers made from specialized materials like neoprene or EPDM, which offer better heat resistance.

Are these rubber stoppers suitable for aggressive chemicals or high pressure?

These Enjoyist rubber stoppers are ideal for use with non-aggressive or concentrated solutions. They are not recommended for highly aggressive chemicals, solvents, or high-pressure applications, as the natural rubber material may not withstand such conditions. Always verify the chemical compatibility and pressure rating for your specific application before use.

Ideal For General Lab Use, Not For High-Pressure or Aggressive Chemicals

This assorted set is perfect for general laboratory sealing needs, including test tubes, flasks, and bottles with non-aggressive solutions. However, these stoppers are not designed for high-pressure applications or use with highly aggressive chemicals or solvents, as the natural rubber may degrade. If you require stoppers for autoclaving at high temperatures or for use with strong acids or bases, consider specialized materials like neoprene or EPDM. For everyday lab tasks, this assortment offers excellent value and convenience.

How to use

Select the Right Size — Measure the inner diameter of your test tube, flask, or bottle opening in millimeters. Choose the Enjoyist rubber stopper whose bottom diameter is slightly larger than your opening to ensure a snug, sealing fit.
Prepare the Stopper — If the stopper has surface dust from packaging, gently wash it with water. Ensure the stopper and the opening of your glassware are clean and dry for optimal sealing performance.
Insert and Seal — Firmly insert the selected stopper into the opening of your glassware. Apply gentle, even pressure to seat it properly, creating a secure seal suitable for non-aggressive solutions or storage.
