Key Features

Product Details

Quality Details

Tissue culture flasks are engineered for the cultivation and maintenance of mammalian, microbial, or insect cell cultures. They are particularly well-suited for maintaining seed cultures, which can be used to inoculate tissue culture plates and dishes. This model is non-treated, suitable for suspension cell lines.

1. What does “TC treated” mean?

TC (Tissue Culture) treatment refers to a surface modification that enhances cell attachment. The flask surface is treated to make it more hydrophilic, allowing adherent cells to spread and grow more efficiently.

2. What is the difference between plug seal and vented caps?

Plug seal caps provide a tight, closed system when fully tightened, minimizing contamination and evaporation. Vented caps allow gas exchange (CO₂/O₂) without loosening the cap.

3. What types of cells can be cultured in a 25 cm² flask?

4. What is the recommended working volume?

This ensures proper nutrient availability and gas exchange.

5. Are these flasks sterile and ready to use?

Cell Culture Flask, 150cm2 U-Shaped Canted Neck, Plug Seal Cap, Non-Treated, Sterile 5/pk, 40/cs

NEST Cat. No.: 720011
Selling unit: Case of 40

Cell Culture Flask, 150cm2 U-Shaped Canted Neck, Plug Seal Cap, Non-Treated, Sterile (Cat. No. 720011)

Key Features

Product Details

The U-shaped, canted neck features an enlarged bottleneck that, without affecting normal use, allows pipettes or cell scrapers to easily and flexibly reach every corner of the flask The bottleneck is expanded to match the large-mouth design of the NEST BioFactory enabling compatibility with accessories, improving tube connections, and supporting secure closed transfers

Quality Details

Nest U-shaped flasks offer a modern upgrade to the classic tissue culture flask. Their rounded shoulders expand the usable growth area and allow easier access to all surfaces with a cell scraper. A wider mouth accommodates 50 mL serological pipettes and ensures compatibility with Nest aseptic transfer system accessories. These systems streamline cell passaging workflows while minimizing the risk of contamination.

What is a U-shaped (canted neck) cell culture flask?

A U-shaped or canted neck flask is designed with an angled neck that improves access to the growth surface. This design makes it easier to perform pipetting, media changes, and cell harvesting while reducing the risk of contamination.

What is the NEST equivalent to Corning 430825?

NEST offers a U-shaped (canted neck) cell culture flask that serves as a direct alternative to Corning 430825, with comparable dimensions, surface treatment, and performance.

Are NEST U-shaped flasks tissue culture treated?

Yes. NEST U-shaped flasks are available with tissue culture (TC) treatment, providing a hydrophilic surface that supports attachment and growth of adherent cells such as HEK293, CHO, and fibroblasts.

What are the advantages of a canted neck design?

What types of cells are best suited for these flasks?

Non-treated versions (if available) are suitable for suspension cells such as hybridomas and lymphocytes.

Are NEST flasks compatible with standard lab equipment?

What cap options are available?

Are NEST flasks sterile and ready to use?

How do NEST flasks compare in performance to Corning flasks?

This makes them a reliable, cost-effective alternative to Corning 430825.

When should I choose a U-shaped flask over a standard straight-neck flask?

Can these flasks be used for large-scale cell expansion?
