Nice seal and sturdy build

Excellent and efficient communication and delivery, all questions answered promptly

This company did an amazing job shipping us the kill jars quickly. There was excellent communication, response time, and shipping time. The University of Florida will definitely be using this company again in the future!

This product works fine, except for the fact that I notice quite a bit of odor from the 16oz jar even after I have tightened the lid as much as possible. This is particularly noticeable when I place the "charged" collecting jar in a plastic re-closable bag to protect it from damage while I am carrying it around. When the bag is opened, the trapped odor/fumes are especially strong coming from the bag where they have collected due to leakage from the jar. Note that while this is my first collection jar, it appears to me that the Ethyl Acetate liquid that I place in the jar loses it strength too quickly. So, I wonder if this is not related to the "large" amount of fumes escaping the jar as the Ethyl Acetate is essentially evaporating. I really am not sure why this apparent leakage of fumes happens. The glass jar has a metal screw-down lid with what appears to be a white (probably cardboard) liner. When tightening the lid as much as possible (when initially sealing the jar), if one comes back a few minutes later and checks the lid, there almost always seems to be a bit more of a "tightening" turn that can be obtained by turning the lid a bit more. My first thought was that the lid had been sealed to the jar in a cross-threaded/crooked position. But after inspecting the lid once it was tightened, it appeared to be level with the top plane of the jar and no evidence of cross threading was evident. My other theories as to why this situation is occurring include the possibility that the lid is not sitting level with the top of the jar (probably by a very slight amount), so that when tightened this allows some of the Ethyl Acetate fumes to escape. My second theory is that the cardboard liner absorbs some of the Ethyl Acetate fumes inside the jar and these fumes work their way to the outside edge of the cardboard liner (past the outer edge of the jar) and are escaping into the atmosphere where the odor is very noticeable, especially in a closed room or building. I am sure that if this jar had a lid similar to that of a food canning jar, this situation would not occur. However, since canning jar lids have a removable/replaceable liner with a rubber seal, I am not sure if this is would be a workable solution to the problem, or not. If I can find a canning jar lid that will fit the diameter of this collecting jar, I will certainly try this latter solution. The reason I think this might work is that (1) the canning jar lid liner is metal and will not absorb odors, and (2) the rubber outer edge seal of the lid liner will prevent any odor from escaping from the collecting jar. As the lid liner become worn along the rubber seal at the edge, it can easily be replace with a new one. There also might be other advantages to this type lid. For example, when removing the lid for collecting an insect, one can first remove only the outer tightening ring leaving the jar "sealed" to a degree by the metal lid liner. When the ready to make the insect collection, the metal lid liner can be quickly removed, the insect is then placed into the jar, and the metal lid liner quickly put back over the jar opening to minimize the amount of fumes escaping. The metal screw-down outer ring (like on a canning jar) can then be installed on the collection jar and tightened a minute or two later.
