Matter funnels into the supermassive black hole from a ring of material circling around it and called an accretion disk.
The filter funnels the signals received from many directions into separate photodetectors and improves reception by combining the energies of the beams.
For prefilled syringes without attached sterile needles, expel the contents of each syringe into one or two separate membrane filter funnels or into separate pooling vessels prior to transfer.
