We are using Radiation Sterilization after packaging our products. Expiration date is indicated on products packaging. Those without indication can be used for 2 to 3 years after production.
We recommend that you change half volume of the medium by using micropipette gently. Notice the non-adhesion spheroid may be removed when changing medium. Please do not set the pipette tips close to spheroid in medium. Slowly aspirate is highly recommended.
We are doing X-ray sterilization after packaging our products. Generally, plastic products may be deteriorated after X-ray sterilization. Our products can be used until their expiry date, but those without their expiry date indicated can be used for 2 to 3 years after production.
