PR1MA™ Microcentrifuge Tubes

PR1MA™ Microcentrifuge Tubes are engineered for durability, clarity, and performance in high-demand laboratory environments. Choose from two cap styles to suit your workflow - the boil-proof cap (MCT15) for high-temperature applications or the large boil-resistant cap (MCT17) for enhanced labeling and easy handling.

Constructed from crystal-clear polymer, each tube allows effortless sample visualization while ensuring maximum integrity during centrifugation up to 20,000 × g. The optional NoStick® low-retention resin prevents sample loss and ensures reliable recovery of precious materials.

Designed to endure extreme temperatures from –80°C to +121°C, PR1MA™ tubes are ideal for both cryogenic storage and autoclaving. Every tube is certified free of RNase, DNase, DNA, PCR inhibitors, and pyrogens — ensuring the highest standard of purity for molecular biology, PCR, and diagnostic research.

PR1MA™ Microcentrifuge Tubes deliver the clarity, performance, and confidence your lab depends on - from prep to preservation.

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.

Main Attributes

• 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

TPP Tissue Culture Test Plates

TPP Tissue Culture Test Plates are designed for consistent, high-quality cell culture and microscopy. Air vents in the base of each plate allow uniform airflow between stacked plates, ensuring even temperature distribution and preventing condensation. The absolutely flat, well-only treated growth surface promotes uniform cell growth without clumping, while crystal-clear transparency delivers excellent imaging quality.

Alpha-numerical labeling between wells and color-coded markings on the lids ensure correct orientation and easy identification during experiments. Available in 6, 12, 24, 48, and 96-well formats, TPP plates stack securely, feature textured grips to prevent accidental lid removal, and offer F-base (flat) or U-base (U-bottom) geometries for 96-well plates. Perfect for reproducible tissue culture, microscopy, and high-throughput applications in research and industry.

Key Features

• Air vents in the base provide consistent airflow between stacked plates.
• Flat growth surface promotes uniform cell growth without clumping.
• Crystal-clear transparency ensures high-quality microscopy images.
• Treated only on well bottoms to enhance cell attachment and proliferation.
• Yellow marking areas on lid and plate ensure correct lid orientation.
• Ridged and textured grip areas allow secure handling and prevent accidental lid removal.
• Alpha-numerical labeling between wells supports easy orientation during microscopy.
• Secure stacking across all plate sizes (6, 12, 24, 48, 96 wells).
• 96-well plates available in F-base (flat) or U-base (U-bottom) geometries.
• Sloped edges ensure lids fit in one correct position only.

Quality Assurance

• Made from optically clear polystyrene for excellent viewing.
• Sterile, packaged individually or in convenient multipacks.
• Lids feature anti-contamination rings that line up with each well.
• Certified DNAse/RNAse, nucleic acid, and pyrogen-free.
