Polypropylene Plasteur® Pipets
Plastic pasteur pipets.
Polypropylene Plasteur® Pipets provide the precision of glass pipets with the added safety and durability of plastic construction. Designed with a fine tip, these pipets are ideal for precise aspirating.
Polypropylene pipets offer strong chemical resistance, making them suitable for many standard lab applications. Unlike traditional glass pipets, they are flexible, shatterproof, and more durable, helping to reduce breakage, product loss, and safety hazards.
Their non-shattering design eliminates the risks associated with broken glass, while the flexible material helps prevent glove or skin punctures. These pipets also simplify lab safety procedures by eliminating the need for sharps disposal and are autoclavable for added convenience.
Main Attributes
- Accurate aspiration with a fine tip design
- Durable polypropylene construction provides excellent chemical resistance
- Shatterproof design, no breakage or glass hazards
- Flexible material helps prevent punctures and injuries
- Eliminates glass waste handling concerns
- Autoclavable
With improved durability during shipping and handling, Polypropylene Plasteur® Pipets are a reliable and safer alternative to glass pipets for everyday laboratory use.

How to Choose the Right Scientific Dewar Containers
The ideal liquid nitrogen (LN2) storage dewar for your facility or project will depend on how you plan to use it.
Consider your needs regarding:
- Footprint and capacity: If you have limited space or require portability, opt for a smaller model. Larger models will increase your LN2 capacity and reduce refill frequency
- Static hold and evaporation rate: The less evaporation that occurs, the longer you can go without refilling LN2. However, especially sensitive materials may require a model that prioritizes hold time over evaporation rate
- Access: Smaller device necks can conserve more LN2 when dispensing, but may be more challenging to use and slow down operations that require frequent dispensing
- Portability: The more compact your laboratory dewar flask is, the easier it will be to transport and use in field research. If portability is not a concern, a larger model may offer more benefits
- Accessory compatibility: While IC Biomedical’s catalog usually aligns with standard accessories (e.g., canisters, racks, transfer lines), check the specifications of the models you are reviewing to make sure they will integrate with your existing workflow
Want help making a decision? Contact us. MIDSCI™ can recommend options based on your LN2 usage, refill frequency preference, and handling constraints.
