I feel like I’ve seen this answer before, but I can’t find it here in the forum.  I also don’t see it in the Guide.

If I use a 1 ml syringe, how much is 1 drop?  I’m planning to use the syringe to measure DMSO.  I’ve never used DMSO yet, so I want to make sure I do it correctly.

We are using an international standard for liquid measurements, which is 20 drops per 1ml. One ml ÷ 20 drops = 0.05ml per drop of liquid. 

   

When using DMSO in a syringe, you may want to check compatibility of the syringe plastic and rubber parts with DMSO. I would also look at using a glass pipette. They do have a plastic bulb to draw up liquids, so just make sure the DMSO does not reach the bulb. There are also glass eye droppers available. You can find both on Amazon.com

I really appreciate the detail of your reply!  It’s very important to get this right.  

So now this leads to a whole new set of questions.  I’ve been using plastic syringes to dose my cats…I wonder if I’ve been harming them with the plastic?  It seems like I would need to use a glass pipette instead of a syringe.  This may explain why some aren’t improving.

The descriptions of syringes on Amazon just say quality plastic and they’re from China.  No idea what “quality plastic” they’re made of!

Besides Amazon I wonder where I could get a glass syringe or if the pipettes are better?

I like to use glass if it is available. 

The descriptions of syringes on Amazon just say quality plastic and they’re from China.  No idea what “quality plastic” they’re made of! I think everything is made in China! 

Besides Amazon I wonder where I could get a glass syringe or if the pipettes are better? I often buy from www.aliexpress.com/  Just received a 100ml glass syringe yesterday from AliExpress. It cost about $10 USD.
