Mineral oil is being poured into a glass lab-grade funnel, and the camera pans down a glass tube, and then cuts to a close up of a thermometer, with someone wrapping a rubber band on its end.
A chemist licks the end of a plastic needle, then secures it in the band, the dredges it through a pile of what's probably heroin. He puts the thermometer above the glass tube, then lights a gas lamp and puts it under the contraption.
"Blast off," he says, then begins to read and evaluate the numbers as Sal paces, watching the numbers go up.
Weinstock puffs at a cigar.
The test completes and the chemist says it's the purest heroin he's ever seen.
The chemist says goodbye and Weinstock and Sal talk numbers: there's 60 kilos of dope, which is worth half a million (that's 3.21 million bucks in 2015 dollars).
Sal wants to go ahead as soon as possible, because Charnier is impatient, but Weinstock cautions him to chill out: he can gather the money to make the deal, but it always pays to be patient—if he were more patient, the cops wouldn't be tailing him.
