Cia thiab ceev faj
9 9-BIS(4-AMINO-3-FLUOROPHENYL)FLUORENE should be stored in a tightly sealed light-resistant container at 15–25℃, in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Khaws nws cais tawm ntawm cov kua qaub uas muaj zog, cov hauv paus, oxidizing cov neeg ua haujlwm thiab cov dej noo kom tsis txhob muaj tshuaj lom neeg uas ua rau muaj kev puas tsuaj zoo.
Thaum tuav, hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv, tsom iav thiab lub tsho hauv chaw kuaj mob, thiab ua haujlwm hauv lub fume hood los tiv thaiv kev nqus plua plav thiab daim tawv nqaij / qhov muag. Tshem lub thawv tam sim tom qab siv. Kev pov tseg pov tseg nruj me ntsis raws li cov cai tswj kev phom sij hauv zos.
