Gill's Hematoxylin is a specially formulated solution for use as a biological stain for the nuclei and nuclear chromatin of normal and abnormal cells whether in whole or sliced cells. Our Gill's Hematoxylin is designed to use at its full strength. It is microfiltered prior to shipment; therefore, filtration before use is not required. For repeated use further filtration is recommended. At the discretion of the user, the Gill's Hematoxylin No. 2 and No. 3 may be diluted with ethylene glycol (25% is recommended) to produce a weaker stain solution.

Preparation of Glycol Methacrylate
An alternative fixative to Formalin and Formaldehyde.
EMS is proud to introduce an alternative to Formalin and Formaldehyde in many different applications.
Our unique kit comes premixed and measured and ready to use. The kit consists of 2 vials: Solution A & Solution B (Absolute Ethanol, Glyoxal Solution, Acetic Acid and water).
Add solution A to solution B. Vortex the two solutions together and bring to a pH of 4.5 with the addition of NaOH 1M. The solution needs to be used immediately once mixed.
