Plague sample

The plague sample  is a quest item given to the player by Elena during the Biohazard quest. The player must smuggle it into the gated area in the south-east of Varrock and give it to Guidor along with some ethenea, liquid honey, sulphuric broline and touch paper. As with the ethenea, liquid honey, and sulphuric broline, this item will disintegrate if you teleport with it in your inventory. Banking the item is the easiest way to avoid this.

Player who teleport with the sample receive the message:

"the plague sample is too delicate... it disintegrates in the crossing"
