  • What glass “dish” should I use for my hotplate?

    Posted by suswang8 on October 12, 2022 at 3:49 am

    I am getting a new hotplate and want a “double boiler”-kind of set up where I have a glass dish on the bottom, add water too it, and then add my beakers into a warm bath.  I saw these online, but I am hoping there is a cheaper alternative under a different name?  
    I guess I could use this, but is the glass too thick for my purposes?
    Thank you.

    Sorry — I just realized my hyperlinks bombed.

    Let me try this again….

    Here is the product that I was thinking I should use as the “base” for my water bath, but I am wondering if there might be a cheaper alternative under a different product name?

    As a cheap alternative (assuming no one has a better suggestion), this is what I was thinking I might be able to use, but will the glass be too thick?

    Thank you.

    The cheap alternative should work. As long as you can boil water in it and it is pyrex, that will be fine.

    actually, that is a good point: it is not borosilicate glass, so I’m not sure how heat-proof it will be.

    We opt for good quality stainless steel pots. I find them a lot more robust and easier to use.

    We use SS containers as well.
