In recent years, there has been an increasing demand for polypropylene, the plastic that makes pipette tips. However, a manufacturing plant fire has taken out 80% of the country's supply of used pipette tips. Currently, demand is at an all-time high, and prices are soaring as a result. In order to address this issue, manufacturers are exploring alternative materials for tip boxes.
While most pipette tips are made from low-density polyethylene, some are made from high-density polyethylene. While polypropylene is a relatively safe material for laboratory use, it does contain some phthalates that are harmful to human health and the environment. Regardless of the material used, these are still considered safe in most places. Luckily, there is a wide variety of plastic available for these products, and the choices are many. If you need a tip for a certain chemical, it may be made from a high-density polyethylene or a natural polypropylene resin. The bottom line is that you should make sure to recycle these pipette tips when you are finished using them. They are durable enough to be reused a hundred times and are very convenient to use.
Pipette tips are usually made of low density polyethylene or polypropylene. It's a transparent, colorless plastic that's good for most applications. It has a broad range of temperature and chemical inertness. There are some additives in polypropylene pipette tips. The most common are the color-developing materials and the release agent, which helps the tip separate from the mold quickly. The no-additive pipette tip is rare. It's made of high-density polyethylene terephthalate. You can purchase high-quality plastic pipette tips by avoiding low-density polypropylene. These are the most expensive tips in the market, so they are made of recycled material.
When purchasing plastic pipette tips, look for a manufacturer that makes their pipette tips from virgin plastic. Some companies may mix recycled polypropylene with virgin plastic. This is not safe, and there's a high chance that contaminants can get into the laboratory. Fortunately, the company Labcon uses only virgin plastic and grinds it into the pipette tip boxes. This helps ensure that there's no waste.
Although polypropylene is commonly used in pipette tips, it's important to choose one that is free of additives. LDPE is not a toxic substance, but it is used to create a release agent for pipette tips. This prevents them from sticking together in the mold. It's best to choose a tip that is free of additives. This is not common, but it's worth looking for.
Pipette tip boxes can be reused. The pipette tips are reused over again, and they are available in different sizes, and they are packaged in a way that minimizes waste. To help reduce the amount of waste, these tips can be used again. Aside from being reusable, they are also recyclable. They are also packaged in molds to minimize plastic waste.
Besides being recyclable, pipette tips should be properly cleaned. If the tips are contaminated, they must be thoroughly disinfected. The best solution for this is to use a pipette tip that has an air cushion in the middle of it. The air cushion will protect the pipette from contamination. It's important to wash and clean the tip before use. You should also consider the materials that are used in the pipette tip.
Fortunately, most pipette tips are made from low density polyethylene or polypropylene. These materials are acceptable in most areas of the United States, but if you're unsure of what type of resin you'll need, check the materials label on the box to make sure you're buying a durable one. You can even find recycled plastic pipette tips at a local pharmacy.
