    Can somebody help me with this.

    In one of his experiments Pasteur prepared a nutrient-rich broth in a swan-neck flasks and he boiled the broth, then he left the flasks open to the air, and no microbes were found in the broth, but when he cut off the neck of the flasks the broth became cloudy with microbial growth.

    Can somebody check for mistakes. Thanks.

    Re: Can somebody help me with this.

    I would suggest you make this into two or three sentences instead of one.

    This is a problem: a swan-neck flasks -- since you use the plural after that, delete the "a."

    I'd also put a comma after that final "flasks."
    I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
