Closures, plugs and pouring rings in various designs

easier and therefore, experiments easier to conduct. Pouring rings are available in a range of thread sizes. 

PP and PTFE multiple distributors for bottles offer a high chemical resistance. PP (polypropylene) is very similar to HDPE-type plastics, however, PP is slightly harder and more heat-resistant. Whereas PTFE distributors for bottles (polytetrafluoroethylene) are hydrophobic with resistance to high temperatures, but can also display non-stick properties. These multiple distributors for bottles are available in a variety of thread sizes. 

Thread adapters can be essential in the lab as they allow accessories with incompatible thread sizes to be fitted together, and can also be purchased from Fleischhacker. 

Glass caps and the correct sealing options are important for your particular glass laboratory bottle. However, a Kapsenberg cap may be preferable for the choice of metal material, as it aids gripping when attaching the cap to a straight neck culture flask.

Ensure your bottles and containers are easy to identify with colour-coded bottle tags and adhesive labels. Furthermore, ensure the reproducibility of your experiments with tamper evident closures which prevent tampering, theft and product switching. Made of PP and available in a variety of thread closures and colours. Port system-type screw caps are also available in a variety of colours and thread sizes but with the added benefit of a hose connection port. At Fleischhacker, we also provide tools for opening and closing, for example, silicone rubber seals are also essential for sampling. Screw caps are available in PP, LDPE and PTFE, and in a range of colours. Additional screw caps may be purchased to permit the opening and closing of the Duran® bottles, some with only a three-quarter turn for ease of use. For experiments which require the centrifuge, you can find reliable PP screw closures with silicone gaskets. Wash bottle attachment caps come in a range of sizes, made from LDPE.

Use silicone lids to protect your solutions while they are still in the laboratory vessels. These are not only stretchable but also resistant to extreme temperatures and chemicals. Stoppers can also be used to protect solutions, available in various sizes and colours and made of either neoprene, chloroprene, natural rubber, cork, or silicone. A mix of PTFE, PP, and glass ground stoppers also help to contain solutions which are stored in tubes, some with hexagonal-shaped heads which are a grip aid.
