Pen-Fix                                                                                                             

Pen-Fix is a uniquely buffered alcoholic formalin fixative. It is designed to perform well with fatty or thick tissue sections. Fixation and dehy-dration occur simultaneously and the penetration rate is three times faster than that of 10% Neutral Buffered Formalin. Pen-Fix is an excellent frozen section fixative and can be used on all open or closed tissue processors and in the grossing room. It is recommended for use in the second and/or third stations of the processor as a secondary fixative.
