Pyrex Corning 1395-250, 250ml Round Media Storage Bottle, with GL45 Screw Cap (Pack of 2)

These media storage containers work well. The lids do not leak, and the glass is extra thick. Like most Pyrex containers and beakers, the letters and graduated measuring marks will not come off easily. I have not tried taking them off with a strong acid, but they are holding up well so far.

Top quality, never disappoints. I use in a pressure cooker and it’s perfect!

I use these for microbiological growth media preparation, sterilization, and storage. I purchased these and the generic blue-capped ones on here. As I expected from Pyrex, these are of much better quality and worth the higher price.

They are PERFECT for pouring agar. im a huge fan of these, will be ordering another set when possible

If you are looking for a resistant glass like actual "pyrex" glass, this is NOT the one. I put an already cold beverage in the 2 bottles , then placed them in frezzer, and next day I found both broken. Waste of money.

Use them told hold an additive for my Cummins. I buy in bulk then split it down to these jars.

Good for making agar

After 1 round in the pressure cooker the inner lid gasket has already failed. 1 was ok the other is already useless.
