You certainly don't need expensive lab equipment to do philosophy. But a lot of philosophy is about interacting with others, about learning other people's ideas, considering them, coming up with your own reactions to those, and getting feedback as they consider your reactions. That kind of feedback loop is difficult if not impossible to do on a deep level without going to school for philosophy.
I'm sure there are people who have a very deep knowledge and understanding of philosophy despite being self taught, but I would be surprised if there were very many of them these days. It used to be a lot easier in the past, when there wasn't as much to learn. But even going back 2500 years to Plato's time, there was a great role for learning in the Academy, from which modern universities descend.
Of course, it doesn't take a university education to "do philosophy". You could certainly "philosophize" without any education (and a lot of people do, often not realizing that that's what they're doing). But I guess it all depends on what your goals are, and how deep you want to go.
I've personally found discussing what I'm learning with other students and with professors to be critical for my own education. I think philosophy is often as much of an oral tradition as it is a written one.
Finally, it requires an enormous amount of self-discipline to read and write as much as you would in getting a university education in philosophy, if you're going to try to teach yourself. A lot of people think they can just teach themselves, but later find to their regret that they can't without the structure provided by classes, schedules, graduation requirements, and teachers.
