Free Control Slides

Histology Control Slides

Beginning this week, all 22ct histology control slides (see link below) bought will now come with 3 extra unstained slides FREE. Buy 22 get 25 controls.
Histology Control Slides

We have 24 different human histology control types to choose. Mouse and rat normal tissues are also available as control slide sets (inquire). Some controls like Fite, fungus, gram and helicobacter pylori are four of our most popular controls. They go fast, get them before they’re gone!

This promotion (3 free slides) will be species specific but not necessarily same tissue type. We will try to match same controls as bought but if they are not available, we will throw in another validated control type. If you order hospital grade human tissues you will get 3 similar unstained slides, free. Likewise, if you order Mouse or Rat 22ct, you will get 3 free mouse or rat slides respectively.

Extra slides will be marked with either our slide printer or hand written. Extra slides may or may not be sequentially ordered and will be placed at the back of each box.

Free slides are not guaranteed and will discontinue at anytime. 100ct boxes not included in the promotion.

Grocott’s Methanamine Silver (GMS)

Here is another fungus stain.  Some of the fungi that you might stain with PAS but do not will stain with the GMS.  The silver used must be disposed of properly (not down the sink).  When using gold chloride remember to use plastic forceps, metal forceps will corrode on contact.  All glassware should be chemically cleaned before use to reduce contamination.  Pictures will be coming soon.

Use Control Tissue with known fungi.

Safety equipment: Work under a hood with lab coat, gloves, and glasses.

Special stains protocols

I am trying to figure out what to do about the special stains protocols.  There are about 35 of them.  Putting them on the front page does not seem to be efficient.   I would like them all to be searchable and downloadable, maybe on a different page.  What do you think, does it make a difference?
