Glass Laboratory Jars. Specimen Jar with Knob.
Specimen jars with a Knob on the Lid.
These are made for the laboratory market and are not finished to perfect finish levels. This is in terms of a square view, as it may just be the hand blown swirl seen and loved by many personal shoppers over the years. Getting them is harder and harder and the price sometimes goes up. If a size runs out, it is not so easy to replenish, as a rather large order has to be made before our suppliers in China will deem it worthwhile to make up a shipment for us. No doubt, if your order is large enough we could adjust the quantity availabe for you to book and pay for the order, but it then could be 2 to three months or more away till we can get in the jars. These have a large opening when the lid is removed, and so flour, rice, and all sorts can be stored in them. Even sweet foods have been found to be safe from ants where nothing else was seen to be. The reason is the ground glass to ground glass seal. In particular, the 90mm x 300mm has been out of stock.
