Numbers by each section relate to those in the Safety Data Sheets (SDS). 1) FULL NAME OF CHEMICAL with chemical formula, including ‘common’ name, and grade where possible. (examples: Sodium Hydroxide (NaOH) GPR; Methanol ‘HPLC grade’; Boric Acid ‘ANALAR’) Crystal violet stain 2% Crystal violet in 95% ethanol

PURPOSE FOR WHICH YOU NEED THE SUBSTANCE: (brief description of what you are going to do with it and why) Microbiological stain

QUANTITY /AMOUNT OF SUBSTANCE REQUIRED: (examples: 5g; 250ml; 1000 units; 2 slopes) 20 ml in dropper bottle only 2-3 drops per slide

QUANTITY /AMOUNT OF SUBSTANCE TO BE PREPARED from original above: (examples: 500ml 0.5M solution; 20 petri dishes) Be aware: if what you make is radically different from the original substance A SEPARATE CoSHH FORM WILL NEED TO BE PREPARED. none

I CONFIRM THAT A SAFER ALTERNATIVE CANNOT BE USED NOW REFER TO THE APPROPRIATE SAFETY DATA SHEETS FOR THE SUBSTANCE.
