Insect Collecting Jar, Glass, with Ethyl Acetate (#1108, 1116, BZ0068)

$15.98 USD
Item:8 Oz Jar with Agent

Put down insects the proper way with our Glass Bug Collection Jar. Each jar has a white metal screw-top lid that features a "Poison" label for safety and identification, and a layer of porous plaster at the bottom of the jar. Includes a 30ml bottle of Ethyl Acetate, commonly used as an insect killing agent. It is also useful for relaxing, preserving and de-clumping specimens. Instructions for killing-jar use and SDS sheet included. (EE0068-30)

To prepare for use, pour about 1 oz. of ethyl acetate into the jar, screw on lid and wait until plaster is fully saturated. Then, pour any liquid remaining on the surface back into the container of ethyl acetate. Recharge jars as needed.

How it works: The layer of porous plaster at the bottom of the jar absorbs the killing agent and permits fumes into the jar.  This is the preferred collection method for entomology. 

Available in 8 and 16 oz sizes. Jars are also available without the dispatching agent.

Jar dimensions:

8 ounce - 2 -7/8" Diameter x 3-5/8" Height (73mm Dai. x 92mm H).

16 ounce - 3-1/2" Diameter x 3-3/4" Height (90mm Dia. x 95mm H).

Excellent! Great for beginners

Needed a quick and easy and portable kill jar, so this is a perfect solution. I ordered two — one for me and one for a friend who has no biology training and is interested in insect preservation. I was very pleased to see that the jar and vial of ethyl acetate came with a small rubber dropper and a little slip of paper with some simple instructions for beginners in addition to the detailed chemical data sheet. Haven’t used the jar yet but the seal seems good, and the plaster pour is neat and looks great. Definitely would buy again!

Thank you for the detailed review! We're sure your words will be helpful to other buyers, and we're happy that you're pleased with your purchase. Have a great day!

Strong odor with lid tightened

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.

Thank you for your detailed review! In regard to the ethyl acetate, are you pouring in just a small amount and allowing it to soak into the bottom? Please note that any excess liquid that remains after after a few minutes should be poured out. It can be poured back into to the bottle, if desired. Also, we only use metal lids with plastisol liners for a good seal. They are, in fact, food jar lids. You'll notice the plastisol is applied where it makes contact with the jar. A cardboard liner wouldn't be nearly as effective. Please be sure to read the SDS form and follow all precautionary measures. Good luck!
