Highly Resistant Polypropylene ConstructionCrafted from medical-grade polypropylene, these L-shaped cell spreaders provide exceptional durability and resistance to common laboratory chemicals. The one-piece molded design ensures no joints or crevices, minimizing potential contamination and maximizing longevity under regular laboratory conditions.
Optimal Spreading Edge and Ergonomic DesignSmooth, rounded edges allow for gentle, uniform spreading of samples without damaging agar plates. The ergonomic, non-slip handle enables comfortable and controlled handling, even during lengthy procedures. This makes sample distribution more efficient and consistent throughout microbiological and cell culture studies.
Sterility and Packaging FlexibilityPre-sterilized and non-pyrogenic, each spreader is ready for direct use in sensitive laboratory environments. They are conveniently available as individually wrapped units or in sterile bulk packs, catering to various scales of laboratory operations and reducing risks of contamination.
FAQs of 148mm Long L-Shaped Plastic Polypropylene Cell Spreaders:
Q: How are these L-shaped cell spreaders used in laboratory settings?
A: These spreaders are designed to distribute bacteria or cells evenly over agar surfaces in microbiology and cell culture laboratories. The smooth, rounded edge allows for gentle and thorough sample spreading without causing damage to the medium.
Q: What are the benefits of polypropylene material in cell spreaders?
A: Polypropylene offers high resistance to commonly used laboratory chemicals, durability under autoclave temperatures (up to 121C), and ensures a lightweight design. This makes the spreader reliable for repeated laboratory exposure and safe to use in sensitive environments.
Q: When should I use sterile, individually wrapped cell spreaders versus bulk packs?
A: Individually wrapped, sterile spreaders are ideal for preventing cross-contamination and are preferred in high-precision or sensitive applications. Bulk sterile packs are more suitable for high-throughput labs where sterility is maintained during handling and usage.
Q: Where are these L-shaped cell spreaders commonly applied?
A: They are extensively used in bacteriology, microbiology, and cell culture laboratories for tasks involving uniform sample distribution on agar plates. Their design caters to practices requiring non-damaging, consistent spreading.
Q: What process ensures the sterility and safety of each cell spreader?
A: Each cell spreader is pre-sterilized and packaged either individually or in sterile bulk pouches under ISO-certified conditions, ensuring they are non-pyrogenic and safe for direct laboratory use.
Q: Can non-sterile versions be made sterile for reuse?
A: Yes, non-sterile polypropylene spreaders can be autoclaved at temperatures up to 121C, making them safe for use after sterilization. However, they are designed for single-use to minimize the risk of cross-contamination.
Q: Why is the L-shaped design significant for accurate sample spreading?
A: The L-shaped structure and smooth spreading edge facilitate uniform distribution of liquid samples across the entire agar plate surface. This promotes reliable and reproducible results in various microbiological applications.
