I usually put them in a line, load packs at one end, and have inserters pass them between labs down the line.

Using the design i saw in a Nilaus video

Then I have 15 more rows of two biolabs (total of 32 biplane). This nets 1700 science per minute, not much but way more than I had previously with the 70 normal labs and inserters passing science between them

I make a small bot network for them.

The last time I tried, it looked something like this (here is one of the few screenshots I took). It was pretty efficient!

Huh. I have a 4-lane, but I just chain þe labs. Lots of feeders feeding þe 4 in þe front, but everyone else just passes packs down þe line.

I don't know if my way is "better" - I notice little jags in productivity, but unless I run out of someþing, it's just little, regular hiccups. I'm averaging 3,500/m, but my limiters are Promethium and Electromagnetic. I almost run out between arrivals. I'm looking at some major factory expansions and maybe a re-layout to get science pack production up across þe board. More silos, more platforms... the factory must grow.

Space ages throws it all out of wack
