Hey dieselenthusiast, the Biopro and other reactors like it are real scams. I paid only $800 for my first reactor and even that was way too much.
Are you serious?

Is this really as good of a processor than the BioPro? Will this kit pass the ASTM standard?

No, it will not meet ASTM specs if good oil is not used and you do not titrate. But neither will the Biopro if you dont titrate and use low ffa oil. The biopro uses a two stage acid base process to convert the oil. If you do not titrate
EVERY batch of oil you will not have full conversion and thus not have ASTM spec fuel. The Biopro uses a guestimate with the reactants based on a neutrally titrating oil such as NEW oil. I don't know about you but I don't want to buy new oil for $3 a gallon then spend another $ or more when I could just buy D2 for the same price.
Contrary to UFO's statement about heat, I can attest that it will handle temperatures of up to 190f without melting or even deforming. Since you will never be able to produce BD at a temp greater than 160 it will never overheat.
The PVC plumbing on my unit has held up to production for two years and never have I had any leaks at all except when I did not mix my methoxide long enough and the transfer pipe was left full oh KOH granules for a week. 1 hour and $10 to fix that and away it went again.
The Biopro has timers on it which allow you to switch it on and walk away until you have to start the next stage of processing, Just like the $6 timer on mine. Contrary to what they would like purchasers to think, they have the same number of steps to perform as the Ebay reactor, but they do have shinny buttons.
The makers claim that the reactant chambers are sealed for safety, Yeah the loading orifices are sealed but the chambers are vented to the air just like every other reactor. They still have to be used in a very well ventilated area.
The Biopro is an excellently put together and pretty piece of equipment, but it cant do magic. The chemistry is the same as all other processors use, the time invested is the same, the money is ridiculous. For most home brewers the point of doing it is to save money, $8000 will take a LONG time to recoup.
I'm not trying to plug the units sold on ebay or say that the Biopro is not very well built. I don't even approve of the crazy price of the poly ones sold on ebay. No one should tell you what to buy with your hard earned money, but I do think that you would benefit from some more research on processors, hopefully you won't be misled by someone who just wants to cash in on the Biofuel wave.
