Culture plate aid

A method of imaging a well in a multiwell plate, comprising:

• applying a cover to the multiwell plate, wherein the cover comprises
• a frame configured for attachment to the multiwell plate;
• a first movable guide member having two elongated side members that extend across the width of the plate, wherein a gap between the side members is substantially equal to a diameter of a single well in the multiwell plate and wherein the first movable guide member is slidable along the length of the frame;
• and
• a second movable guide member having two elongated side members that extend across the length of the plate, wherein a gap between the side members is substantially equal to a diameter of a single well in the multiwell plate and wherein the second movable guide member is slidable along the width of the frame,
• wherein the first and second movable guide member are configured to move independently from each other;
• adjusting the first and second movable guide members until the well is viewable through the gap created by the elongated side members of the first and second movable guide members;
• and
• imaging the well.
