If you want clarity and remove the particulate, then a Buchner Funnel and vacuum flask at the least is what you want. Can be had relatively cheap. There are inexpensive options for a vacuum pump.
I dont do QW, or extract at sub zero temps. I extract at room temperature. I do several washes and combine them. I want it all. I can remediate most anything I dont want.
Use <=1.5um Slow filter paper. Filtering can get 'slow' and take a while, so be patient. You will be rewarded. I am presently waiting for some 0.45um membrane stock to arrive. I am excited to see the difference between solution filtered to 1.5um and 0.45um.
Using Carbon:
- Contrary to popular belief, new research has indicated that the the loss of important cannabinoids due to the use of carbon is negligible.
When I first started using Carbon, I was under the assumption that 'more is better'. So I was using it in excess. Then I read a few articals indicating Carbon will leach cannabinoids. So I began using Carbon very sparingly. Today, I use approx. 10g-12g Carbon for every 28g of flower/biomass.
- You will want to filter the carbon out thru DE (
diatomaceous earth). Using DE will trap fine plant particulate and other undesirables as well. This is why you want to use a slow filter paper with very small pores.
- A lot of people say to make a 1/4" (+/-) 'cake' of Carbon above a cake of DE in Buchner Funnel. I found for best results, is to
mix the carbon directly into the solution and allow to mix for approx. 5mins on magnetic stirrer. Then vacuum filter the solution thru a 1/4"-1/2" cake of DE, using a SLOW filter paper with a pore size of 1.5um or less.
When purged of solvent, the extract is almost the consistency of shatter. I purge the solvent inside my 2L rotovap. I evap off the bulk of solvent in a 500ml or 1000ml boiling flask. Then I filter one more time, and switch to a 250ml boiling flask to finish and purge. My batch size is typically 56g biomass. My biggest extractions being a QP. For me, 56g flower usually yields approx. 10g-11g final extract.
This extract results in a smooth, tastey, and mind bending dab. If using fresh stock, the final extract should taste similar to the flower's aroma.
I highly suggest vacuum filtering thru a Buchner Funnel. Yes, a bit of expense. But again, you will be well rewarded. I got 80% of my labware from Amazon. The rotovap I purchased from LeDab.
This knowledge should be free for all. I am no expert and I dont profess to be one. I am always learning. Just sharing what I have learned, right or wrong. Please correct me if I am wrong. I do not want to spread misinformation. 
I don't think first rinse will be black, but it's not what I wanted. Next time I use bud no trim and nothing that has been sifted for kief. That will probably help out a lot.
