The PTL-100 culture vessel is a square box-style culture vessel that is compact enough for optimal storage, yet large enough to allow for multiple cultures to grow in your gel. PTL-100 is also graduated with 25 mL and 50 mL graduations on one side so you have a guide for how much media you are pouring into your vessel. PTL-100's are molded from autoclavable high clarity polycarbonate plastic which allows for lightweight transportation of your cultures, excellent light transmission, and high durability (virtually unbreakable). PTL-100's are packaged with PTL-100C closures.
Please note: The container and lid is very tight fitting at first, but loosens up after the first autoclave cycle.
