Osmium tetroxide is a white to slight yellowish solid, volatile, with an acrid chlorine-like odor. I'm currently storing a solution of 1% osmium tetroxide (1 gram OsO4 in 100 mL dH2O) in a glass bottle with a plastic cap under a fume hood at room temperature. ;|(�i~���{�"��I��E���_Dhq���jz�㋈����_��=�ӷݼ�G����Cv���m\��8n�t�o��c�d�f�����v7����n ������~x����a�h��y�Q��q��� \�.�bt��;�kg��qx�W�8u���o�+�9������H�ft1� \��u�ܞy|R�W�)6}[��������}���,��a5N���wZ�*�_�4�i�P��AQ�'�����9�a��ֈ�����-}_�~m��;�Y�Zر98���kk\@�e�R���$k`R��и�R)��6�� �$�>����9����a��?���gn�����yXZ�O�?���F�?�;͇l�Զ�C��w�?�:1L�i�V�s̕��_)E����k��_l��Dy�+1����� U`���I'GB���i��W��1���s�w�ZG��ݻ�>z���w�X�[p���LI�͌��۱|s��+=B�^>0e:�ΆO�~����;�=1u T�6߯ӷ�Z�o3�OB$7�gB?��g?B����Lg������:����ù3{R����.��3/�'���Q3��4oφ'�_d���n���'�~O��������;����w:�[�ie�_`���q��P`p���x�w����:���y��6Gl�� 7u�ۖ�/w����}|kΧ��4�=�ݸ���קn���N�=8�g��M��^��a܉=�G{�f�U�_�χ�{.5� �*�xJ�nw�ո{Z�j|�Ӣq��N�ٸ�K?�^��Hg[��v'~�v����7�x���p��cO-+�q��������PF?��գ�8|ͧ �]�[�mk��~�`o�O\J�9�sxAv��a�3�3��q1�q#�ψy�Hv3���[).�H��H҇�d>'樑�0��"��?���Vྺ9#���9��A�[���q�(:~���:{R�bS�<1�'�]\�j�����~R���'�� ��� Wash with 70%, 95% and 100% alcohol, and then with DPBS. following the words 'Lot' or 'Batch'.
