Dear Paul Thomas ,
Although I am not 100% sure of what I am about to suggest (it is worth confirming on the web), TEOS, as a silicate, tends to bond with -OH groups. In this sense, the glass pippette might have some those present, free and available for the TEOS to bond with them. Based on this, I suggest to use plastic rather than glass.
Hope this helps!
Thanks Agustin Forchetti Casarino
We are planning to use TEOS for syntheis we get confused with its usage and waste disposal
Dear Paul Thomas ,
That is great. TEOS tends to be reactive, due to the presence of Si-O-C2H5 groups, either in the presence of acids or bases. There are some examples here:

It is advised to be careful when using it since it "likes" water for example. It is not dangerous at all, but you should not leave bottles open or something similar since it will start reacting with the ambient moisture for example.
Best of luck with your research!

We planning to syntheis Silicon dioxide from TEOS the waste after seperation silicon dioxide, is it okay to store in plastic container or it should only store in glass container
I am very much confused on that prepspective
Dear Paul,
After the synthesis of silicon dioxide, the waste will be mainly based on ethanol. To dispose this waste, I suggest plastic containers. When working with TEOS, always prioritize the use of plastic labware rather than glass.
