Heathrow ScientificHD234526B Moisture Proof Sealing Parafilm, 100mm width x 38m length, 132 mm Width x 135 mm Height x 112 mm Depth, Transparent

Parafilm is synonymous with lab work, every lab I've been in has a roll of it somewhere (often coveted by that one researcher who's work is clearly more important than yours and believes you to be a lesser creature in the grand scheme of scientific discourse and therefore a resource like this is worth keeping away from you).This is that stuff, there are cheaper alternatives and buying them will likely create more problems than the money saved will solve. Buy this stuff, it does the thing lab workers expect it to.Non-sciencey people > Parafilm is like fancy cling film or cellophane, the big difference is the low chemical reactivity, the stretch and sealing properties mean you can cap a tube or flask with reasonable expectation of air/water tightness. And if you want, you can scrunch it up and block stuff with it. I use it sometimes to cover vinegar/oil flasks or to cap storage bottles I've lost the tops of in everyday life..... cause I sometimes do cool science stuff and fail at everyday life stuff (like remembering where caps are)

Good standard product.

There’s quite some variability to the adhesion with the backing paper, but this doesn’t affect use just makes it a pain to handle sometimes.Careful not to cut it too close to the reel or you’ll lose the end in the box.

0 stars. Old parafilm, improperly stored. Peeling away from the backing of the tape all the way around the roll.SHAME ON THESE SELLERS.

perfect

Most of the tape had dried out and although not completely useless it was a tiresome task to use as it kept snapping

Great for sealing agar plates
