Draws a liquid repellent barrier around a section of tissue with the proper surface tension to hold aqueous solutions. Barrier material is insoluble in alcohol and acetone. Remove with xylene. Each makes hundreds of wells.
For use with frozen sections it provides a sticky membrane on the slide that the section is placed on. This eliminates the section from falling off, moving, or wrinkling on the slide during immunostaining procedures. Wide tipped.
A wide tipped pen, designed for use with paraffin sections. The pen provides a sticky membrane to the glass slide which not only prevents paraffin sections from falling off but also keeps the sections flat on the slide.
Coating pen with a wide point (18mm) for fixing tissue sections (paraffin embedded, frozen and formalin sections). The unique pen is unaffected by heat up to 120 degreesC . Can be used in microwave staining, immunostaining, in situ, etc.
Staining guard pen for use at temperatures as high as 120°F. Can be used to perform the peroxidase-anti-peroxidase method, ABC method, and Fluorescent antibodies method with satisfactory results.
