The PT-12 CultureJar is a tall, square, polycarbonate plant tissue culture vessel that is fully compatible with our PhytoCap CultureJar closures (sold separately). PTL-12 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-12'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). 

AUTOCLAVE NOTES:  While this product is autoclavable, it is susceptible to blemishes/white spots after each cycle. We recommend wrapping the vessels in foil prior to autoclaving as this prolongs the clarity. We do not recommend using bleach with this product.
