Usp class plastic tests are designed to assess the biological reactivity of various types of plastics materials in vivo. Usp 35 biological tests / 〈 88〉 biological reactivity tests, in vivo 95 this classification does not apply to plastics that are in- table 2. In the opposite muscle of each animal. Evaluation of skin reactions ( continued) tended for use as containers for oral or topical products, or that may be used as an integral part of a drug formulation. In- vivo usp 88 cytotoxicity testing what is cytotoxicity?
Use an incubator capable of maintaining a temperature of change to read: 37 1 and a humidified atmosphere of 5 1% carbon di- oxide in air. The systemic injection test and the intracutaneous test are used for elastomeric materials, especially to elastomeric closures for which the appropriate biological reactivity tests, in vitro 〈 87〉 have indicated significant biological reactivity. Moderate to severe erythema 3. Swab the skin lightly with diluted alcohol and dry the skin prior to injection. Usp high- density polyethylene rs. • test control extraction containers use only containers, such as ampuls or screw- cap culture test tubes, or their equivalent, of type i glass. These two tests are used for plastics and other polymers, in addition to a third test, the.
Cytotoxicity refers to molecules and compounds that are poisonous to living cells. Originally developed to test drug containers, the class plastics tests are often performed on unmolded plastic resins as well as containers. Remove loose hair by means of vacuum. This chapter is intended as an initial screen to identify elastomeric closures that might be appro- priate for use with injectable preparations on the basis of their biological compatibility, their aque- ous extract physicochemical properties, and their functionality. In- vivo usp 88 cytotoxicity testing cytotoxicity testing, general, medical device testing, parenteral products / by ethide laboratories in- vitro usp 87 vs. Perform the test in a clean area. On the day of the test or up to 20 hours before testing, clip the fur of the animals on both sides of the spinal column.
