I required a one-on-one meeting with the student with the written lab in hand -- then I would read it in front of the student and provide the feedback as if I were grading it.
When "advertising" this option to my students, I stated that the students who met with me, and made the improvements I suggested, usually received good grades on those lab reports.
I did have a student try to give me a disk with the lab to be read on it, but I refused to review the lab -- I required my teacher meeting with the student and the printed out lab report as it was more affective.
Another student met with me but made none of the corrections and simply erased the penciled in comments. This was a surprise but that was the student's choice.
I talk about another strategy for making up missed lab activities (due to absence) in my lab book
"Chemistry on a Budget" available at amazon.com and lulu.com -- it contains 13 labs that require consumable materials you can purchase at local stores -- and it's only $20!
Each lab is presented with two possible report formats -- both labs use the same procedure but each has a different conclusion -- one with 10 questions to be answered as a conclusion, the other with a full laboratory report required. This gives the teacher the option of what type of report is desired, and each version is designed to be just two pages. This way the teacher can photocopy just one 2-sided page per student (saves paper).
It will take a little time to get to you, so order it and enjoy your summer vacation!
Have a good week!
