Stoelting bone cement #51458
Assistance
provided by Ann Bodio, student technician.
Shown are live scallops in air on the
benchtop, attached to plastic netting with Stoelting bone
cement #51458. Also shown are bottles of the two components
of the bone cement, a powdered component and a solvent.
8.57
grams of powder and 5.49 grams of solvent were mixed together
to form a viscous pink paste. Live scallop shells were brushed
with a plastic brush to remove algal fouling. They were blotted
dry and a blob of the pink adhesive was placed on the netting
which was on a piece of waxed paper. The live scallop was
pressed into the adhesive and left for 15 minutes to dry in
air. The scallops plus the netting were then immersed in flowing
seawater. Two of the animals immediately lifted off the adhesive.
Within an hour, another animal had come loose. The remaining
3 animals (out of 6) stayed attached to the netting. |
