Why do Triton X-100 and Tween 20 bottle lids always break?

In summary, the lids on Triton X-100 and Tween 20 are prone to breaking due to the detergents degrading the plastic material and possibly leaching substances into the solution. The cracks tend to occur at the edge where the circular top meets the vertical sides, which may be caused by the accessibility of the detergents and the design and tightening of the caps.

Why do the lids on Triton X-100 and Tween 20 break all the time? The lid on every bottle I've had has always cracked in a very distinctive manner (ie right along the edge where the horizontal circular top meets the vertical sides that screw on).

Thanks

I've noticed this as well. Certainly, the detergents must degrade the plastics (which may be leaching substances into the solution!). The location of the cracks is probably due to a combination of accessibility to the detergent solution, the design of the caps, and the points on the cap that bear the most force when tightened.
 

FAQ: Why do Triton X-100 and Tween 20 bottle lids always break?

What is Triton X-100/Tween 20?

Triton X-100/Tween 20 is a non-ionic surfactant that is commonly used in biological and biochemical applications. It is a detergent that helps to solubilize and stabilize proteins and other biomolecules.

What are the benefits of using Triton X-100/Tween 20?

Triton X-100/Tween 20 has several benefits, including its ability to effectively solubilize hydrophobic molecules, its mildness on cells and tissues, and its compatibility with a wide range of biological samples. It also has a low toxicity and is relatively easy to remove from samples.

How should I store Triton X-100/Tween 20?

Triton X-100/Tween 20 should be stored at room temperature in a tightly sealed container. It is important to protect the solution from light and moisture, as these can affect its stability.

Can Triton X-100/Tween 20 be used with other detergents?

Yes, Triton X-100/Tween 20 can be used in combination with other detergents to enhance its solubilizing and stabilizing properties. However, it is important to determine the compatibility of the detergents beforehand and to use them in appropriate concentrations.

How do I prepare a solution of Triton X-100/Tween 20?

Triton X-100/Tween 20 is typically prepared as a stock solution and then diluted to the desired concentration in the experiment. The recommended concentration for most applications is 0.1-1% (v/v). It is important to mix the solution thoroughly before use and to avoid excessive shaking or vortexing, as this can cause foaming.
