What game is this?

I'm looking for a game for the Apple II.  I don't recall much about it,
but I know:

It was a graphical adventure game, similar to an Infocom game but with
bitmapped graphics

In the beginning of the game you were wandering around in a desert,
perhaps on anothe planet.  Eventually you found a phone booth.  There was
some writing which said "if you're in a fix, try calling MIX" (you were
supposed to interpert MIX as a phone number written in Roman numerals)

There was a puzzle which involved obtaining a certain quantitiy of fluid
by pouring the fluid from one to another of a collection of different
sized beakers.  I think the fluid was some sort of medicine or antidote.

It was published before 1988

The title *might* have included the words "omega" or "lab" (not sure about
this one)

There was a similar game, made by the same company, on which you were
straned on a desert island.

In this other game, there was a puzzle of farmer, cabbage, goat, wolf
genre (farmer wants to get all three across a river in a boat that can
only cary the farmer plus one other thing, goat will eat cabbage and wolf
will eat goat if farmer is not present, etc), only a rickety bridge played
the role of the river and geometric solids played the role of the cabbage,
goat, and wolf

At the end of this other game, I *think* you escaped from the island in a
baloon.

Ok, that's about all I remember.  I know it's not much to go on, and is a
rather strange request, but I'd be very grateful if anyone could help ID
this game, or at least has some suggestions of how I could go about
finding it (maybe there's a comprehensive list of Apple II adventure games
somewhere)?  Thanks in advance,
