Care and maintenance
1
If the slot blot is used with radioactive materials,
decontaminate the 0-ring between uses. You may wish
to purchase a second ring for non-radioactive work.
(See Ordering information.)
2
Wash all blocks thoroughly in a mild water-based
laboratory detergent, then rinse well in distilled water.
Brief exposure to 5% bleach solutions can be used.
Do not use ethanol or other organic solvents. Do not
autoclave the slot blot or wash it at high temperatures.
3
Blot all blots dry immediately. Acrylic can absorb
water, which may cause it to warp.
4
Store the slot blot away from direct sunlight. If you
store it assembled, do not tighten the screws.
5
Store the PR648 slot blot with the membrane cutting
template, flat side-up, between the middle and top
blocks. This will protect the sealing ridge surrounding
the slots.
