PR1MA™ Signature Cell Strainers

Clean, reliable filtration with every use.

The PR1MA™ Cell Strainer system is a fast, efficient, and easy-to-use solution designed to streamline the process of cell isolation and filtration. Ideal for flow cytometry, this advanced straining system is perfect for detaching, isolating, and filtering cells from clusters and tissue samples.

Each cell strainer features a durable polypropylene frame supporting a nylon mesh, available in eight distinct, color-coded pore sizes ranging from 5 uM to
100 uM. Eight fine mesh options offer enhanced control for filtering cell aggregates and clumps, improving experimental precision.

The innovative frame design significantly improves filtration performance. By eliminating the “air-lock” effect, PR1MA™ Signature Cell Strainers promote faster flow-through and better aeration, reducing spillover and processing time.

Key Features

• Available in 8 color-coded pore sizes (5 uM to 100 uM) for precise cell sorting
• Fast flow-through thanks to advanced polypropylene frame design
• Includes universal adapter for tubes smaller than 50 mL
• Compatible with 6-well plates, flat-bottom plates, and culture dishes
• Interlocking and stackable design for improved lab workflow
• Built-in 1.5 mm feet for elevated straining into flat vessels
• Supplied sterile in individual blister packaging
• Certified RNase-, DNase-, pyrogen-, and cytotoxin-free

NEST High-Efficiency Erlenmeyer Flasks

High-efficiency, large-volume culture flasks allow cells to show strong viability with large expression amounts of proteins in the culture of mammalian cells and insect cells. During the culturing process, the use rate of the shaker is significantly increased, and the survival rate and viability of cells are both dramatically elevated.

NEST culture flasks also provide high repeatability, which allows high inter-batch consistency of cell growth and yield.
