Common Types of Plasticware in Labs
Plastic lab equipment is commonly used in scientific research because it's affordable, light, sturdy, and chemical-resistant. Unlike glass lab tools, plastic ones are less likely to break, adding safety to the lab environment. Let’s look at some commonly used labware with a durable plastic alternative:
Beakers
The most common labware, beakers, come in all shapes and sizes, from squat and sturdy for mixing to tall and slender for measuring. Polypropylene (PP) is your go-to for most applications, while Polyethylene (PE) is ideal for high temperatures.
Graduated Cylinders:
One of the most common plastic materials used for graduated cylinders in laboratories is polypropylene. These cylinders are crucial for the accurate measurement of liquid volumes. The transparent nature of polypropylene allows researchers to easily observe and measure the levels of liquids, making it an ideal choice for precise experiments involving the addition or transfer of fluids.
Centrifuge Tubes:
Polyethylene is a prevalent plastic material for centrifuge tubes, chosen for its durability and chemical resistance. These tubes are designed to withstand high centrifugal forces during sample separation processes. They come in various sizes and are essential for tasks such as isolating DNA, separating components of a mixture, or conducting biochemical assays.
Cuvettes:
In the realm of cuvettes, Polystyrene stands out as a widely used plastic material. Cuvettes are transparent cells used to hold liquid samples for analysis in spectrophotometers. Polystyrene cuvettes provide excellent optical clarity, allowing for accurate measurements of absorbance and fluorescence, making them indispensable for experiments involving the analysis of light-absorbing or emitting substances.
Pipettes:
Polyethylene and polypropylene are frequently employed in the production of pipettes, as these materials offer excellent chemical resistance and are autoclavable for sterilisation. Pipettes come in various types, such as micropipettes and serological pipettes. They are used for precise liquid handling, ranging from transferring small volumes in molecular biology to larger volumes in clinical and chemical laboratories.
Spatulas:
Polypropylene is a popular choice for spatulas due to its chemical resistance and ease of cleaning. Spatulas in laboratories are versatile tools for scooping, mixing, and transferring solid and powdered substances. They are indispensable in tasks like weighing samples, preparing solutions, and accurately transferring materials between containers.
Storage Bottles:
For storage bottles, high-density polyethylene (HDPE) is commonly utilised. HDPE is known for its excellent chemical resistance and durability. These bottles are reliable containers for storing various liquids and solutions, ranging from reagents to media. The secure sealing properties of HDPE storage bottles make them essential for maintaining the integrity and longevity of stored materials in laboratory settings.
These are just some of the many types of plasticware in labs that are commonly available in almost every laboratory shop or supplier. The first thing we need to establish before purchasing is what laboratory apparatus can you afford right now as glassware, and then buy the rest as plasticware for now; that is if you want to go all glass.
When Should You Consider Plasticware over Glassware?
Choosing between plasticware and glassware in the lab depends on several factors, and opting for plastic isn't always a clear-cut decision. Here's a breakdown of situations where plasticware might be the better choice:
Safety:
- Plasticware eliminates the risk of dangerous glass shards in case of drops or accidents, making it ideal for settings with students or high activity levels.
- If you're working with corrosive or hazardous chemicals, plastic's lower risk of breakage can minimise potential injuries during spills.
Durability:
- Plasticware generally withstands bumps and drops better than glassware, minimising breakage and replacement costs.
- Plastic's lighter weight makes handling easier, especially for large or frequent manipulations.
Cost-effectiveness:
- Generally, plasticware is cheaper than glassware, making it a budget-friendly option for startups, educational labs, or experiments with high material consumption.
- While reusable glassware offers cost savings over time, the replacement cost due to breakage can be significant. This Plasticware might be more cost-effective in the long run for labs with frequent accidents or activities with a high risk of breakage.
- Disposable plasticware adds disposal costs, while reusable options require cleaning and sterilisation resources. Weighing these against the purchase price is crucial for finding the most economical option.
Convenience:
- Many types of plasticware can be sterilised with autoclaves or other methods, making them reusable for repetitive tasks.
- Colored plasticware helps quickly identify contents, improving organisation and reducing confusion.
- Temperature tolerance: While not all plastic types can withstand moderate heat and cold, some offer an alternative to glassware in specific applications.
Specific Applications:
- Thick-walled polypropylene centrifuge tubes are preferred for their strength and chemical resistance during high-speed spins.
- Plastic bottles and tubes provide lightweight and durable options for storing samples and reagents at various temperatures.
- Portable and shatterproof plasticware is ideal for research in settings where space and risk of breakage are concerns.
However, plasticware also has limitations:
- Not all types of plastic ware in labs resist all chemicals, so compatibility testing is crucial to avoid reactions or leaching.
- Most plastics have lower heat tolerance than glassware, making them unsuitable for high-temperature reactions or heating equipment.
- In highly precise measurements, especially for optical analysis, glassware may offer superior accuracy due to its inherent clarity and stability.
- Disposable plasticware creates waste, so reusability and eco-friendly options should be considered for sustainable practices.
Ultimately, the best choice depends on your specific needs and context. Consider the factors mentioned above, assess the risks and benefits, and consult your lab guidelines to make an informed decision for each individual use of plasticware or glassware.
