Plasticware

Laboratory plasticware is used for sample collection, storage, liquid handling, centrifugation, cell culture, molecular biology, chemical storage, cryogenic preservation, and routine laboratory testing. It provides a lightweight, durable, and cost-effective alternative to glassware for many scientific applications.

The best material depends on the intended use:

Material	Typical Applications
Polypropylene (PP)	Centrifuge tubes, pipette tips, storage containers
High-Density Polyethylene (HDPE)	Chemical storage bottles, carboys
Low-Density Polyethylene (LDPE)	Wash bottles, dispensing bottles
Polystyrene (PS)	Petri dishes, tissue culture products
Polycarbonate (PC)	Carboys, reusable containers
PETG	Media bottles, bioprocess containers
PTFE	Highly corrosive chemicals and specialty laboratory applications

Sterile plasticware is manufactured and packaged to minimize microbial contamination and is suitable for applications such as cell culture, microbiology, molecular biology, and clinical diagnostics.

Non-sterile plasticware is typically used for general laboratory work, chemical handling, storage, and educational applications where sterility is not required.

Many polypropylene products are designed for autoclaving, while other plastics may not tolerate repeated high-temperature sterilization. Always follow the manufacturer's published instructions for the specific product and material.

Products intended for molecular biology often include:

• DNase-free
• RNase-free
• Endotoxin-free (where required)
• Low-retention surfaces
• Certified sterile options

These features help reduce contamination and improve experimental reliability.

Low-retention plasticware is engineered to minimize sample adhesion to the surface of tubes and pipette tips. It is particularly useful when working with proteins, enzymes, nucleic acids, or low-volume samples where maximizing recovery is important.

Consider:

• Required sample volume
• Maximum centrifugal force (RCF)
• Material compatibility
• Closure type
• Sterility requirements
• Temperature range

Selecting the correct tube helps ensure safe centrifugation and protects sample integrity.

HDPE bottles provide excellent impact resistance and are widely used for chemical storage and transport.

Polypropylene bottles offer broader temperature resistance and are often selected for applications requiring repeated sterilization or autoclaving, when supported by the manufacturer's specifications.

Some laboratory plasticware is designed for repeated use, while many products are intended for single-use applications to reduce contamination risks. Always follow the manufacturer's guidance regarding reuse and cleaning.

Store laboratory plasticware:

• In a clean, dry environment
• Away from direct sunlight
• In original packaging until use
• At recommended storage temperatures
• Away from incompatible chemicals

Proper storage helps preserve sterility and product performance.

Depending on your application, look for products manufactured under recognized quality systems and supported by documentation such as:

• ISO-certified manufacturing
• Lot traceability
• Sterility validation (where applicable)
• DNase-/RNase-free certification (for molecular biology products)
• Endotoxin-free claims (where applicable)
• Certificates of Conformance or Analysis, if required

• Pharmaceutical manufacturing
• Biotechnology
• Clinical diagnostics
• Academic research
• Cell and gene therapy
• Food & beverage testing
• Environmental testing
• Chemical laboratories
• Veterinary laboratories
• Industrial quality control

Plasticware is often preferred when:

• Breakage resistance is important
• Disposable products help reduce contamination
• Lightweight handling is beneficial
• High-throughput workflows require convenience
• Automated laboratory systems are used

Glass may be preferred for certain high-temperature, solvent-intensive, or precision analytical applications.

Best practices include:

• Use sterile products when required.
• Open packaging only when needed.
• Wear appropriate PPE.
• Avoid touching critical surfaces.
• Dispose of single-use items after use.
• Store products correctly before use.
