TPP Syringe Filters

TPP Syringe Filters are engineered by scientists for scientists, delivering superior performance in filtering small volumes of tissue culture media, aqueous solutions, buffers, additives, and water. Unlike standard syringe filters, TPP filters provide rapid throughput—3 to 5 times faster—thanks to their premium PES membrane and enlarged filter surface area. With low protein binding, high flow rates, and bi-directional functionality, these filters ensure reliable sterile filtration while preserving sample integrity.

Built with a robust 33 mm housing diameter, TPP Syringe Filters fit securely on 50 mL centrifuge tubes for ease of use in any laboratory workflow. Each unit is gamma-sterilized, DNAse/RNAse-free, and pyrogen-free, individually wrapped for sterility, and supplied in a convenient dispenser box. Ideal for sterile filtration of protein solutions, tissue culture media, additives, buffers, and water, TPP Syringe Filters combine speed, reliability, and ergonomic handling to optimize laboratory efficiency.

TPP Cell Scrapers

TPP Cell Scrapers are designed for efficient and gentle cell harvesting. The innovative pivoting blade head allows effortless angle adjustment with a simple twist of the fingers while maintaining continuous contact with the culture surface. This ensures maximum cell recovery from vessels of all shapes and sizes without the need to constantly reposition the scraper or vessel.

The ergonomically designed handle features raised knobs that provide a secure, slip-free grip even when wearing gloves. Made from flexible, cell-friendly polyethylene, the scraper blade maintains excellent contact with culture surfaces while preventing damage to delicate cells.

TPP Cell Scrapers are available in multiple sizes to provide complete access to all vessel edges, ensuring up to 100% cell retrieval. Each scraper is sterile, individually packaged in easy-to-open peel-off wrappers, and delivered in stackable TPP boxes for convenience and organization.

Key Features

• Pivoting scraper blade - easily adjusts angles without lifting or repositioning
• Gentle polyethylene blade - maximizes recovery without harming cells
• Ergonomic grip - raised knobs provide slip-free handling with gloves
• Optimized access - blade sizes designed to reach every edge of vessels
• High recovery - enables up to 100% cell retrieval
• Sterile packaging - individually wrapped in lint-free peel-off wrappers
• User-friendly storage - delivered in stackable, space-saving TPP boxes

TPP Serological Pipets

TPP Serological Pipets are engineered to deliver precise and reliable liquid handling for cell culture, media preparation, and general laboratory use. Manufactured from premium-grade polystyrene, these pipets provide excellent optical transparency, smooth interiors to prevent cell hang-up, and high durability. Each pipet features highly visible bidirectional graduations with over-volume markings to ensure accurate dispensing and measurement.

For enhanced convenience, TPP offers a patented serological pipet with reservoir (US Patent 8,113,067B). This unique design expands liquid capacity without adding unnecessary length, improving ergonomics inside sterile hoods. The slim tip diameter allows easy access to narrow culture vessels while maintaining drop-free precision and robust performance.

All TPP Serological Pipets are DNase/RNase-free, endotoxin-tested, gamma sterilized, and individually wrapped for sterile assurance. With color-coded cotton plugs, ergonomic dispenser boxes, and compatibility with all standard pipet aids, TPP delivers accuracy, safety, and efficiency for every lab workflow.

Key Features

• Accurate, easy-to-read graduations with over-volume precision
• Smooth, transparent design prevents clumping and ensures clarity
• Patented reservoir option expands capacity without added length
• Ergonomic, slim tips fit narrow flasks and sterile hoods
• Durable, break-resistant polystyrene with color-coded identification
• Individually wrapped, sterile, and ready to use

Convenient Packaging

• Individually wrapped in paper/plastic or plastic/plastic blisters
• Color-coded, stackable dispenser boxes
• Options for single dispensing or bulk dispensing

Quality Assurance

• Manufactured with premium polystyrene for break resistance
• DNase/RNase-free, endotoxin level <0.1 EU/ml
• Sterilized by gamma irradiation

TPP PCV Easy Read Cell Counting System

The TPP PCV Easy Read Cell Counting System provides a fast, reproducible, and cost-effective alternative to traditional hemacytometer counting and expensive automated counters. Using Packed Cell Volume (PCV) tubes, suspension cells can be quickly centrifuged to form a visible pellet that is measured directly in the tube. With either graduated PCV tubes or the Easy Read Ruler, researchers can achieve accurate, objective cell counts without the time, labor, or subjectivity of microscope-based methods.

Designed for versatility, the TPP PCV System supports mammalian, insect, and microbial cell cultures, offering consistent results across multiple cell lines. The method requires only a 1-minute spin at 2500×g in a standard centrifuge, enabling multiple samples to be processed in parallel with minimal effort. By establishing a one-time standard curve for each cell line, labs can streamline workflows and eliminate repetitive counting steps.

Key Advantages:

• Quick and reproducible results without dilution or subjective analysis
• Compatible with bacteria, yeast, mammalian, and insect cell suspensions
• Enables parallel processing of multiple samples for higher throughput
• Disposable, sterile PCV tubes eliminate cleaning and cross-contamination risks
• Cost-effective and reliable compared to automated cell counters
• Sterile, gamma-irradiated, and certified DNAse/RNAse- and pyrogen-free

The ergonomic design of the PCV tubes ensures precise measurement, while the soft polyethylene construction prevents sample damage. Whether using the graduated capillary model for direct readouts or the Easy Read Ruler for fine-scale quantitation, the PCV Cell Counting System offers unmatched accuracy and user convenience.

Ideal for academic, clinical, and industrial labs, the TPP PCV Easy Read System simplifies cell culture workflows, reduces waste, and enhances productivity—making it the modern replacement for outdated hemacytometer counting.

Functional Features

• Direct quantitation of suspension cells without dilution
• Assay multiple samples simultaneously in standard centrifuges
• Cells spun down in just 1 minute at 2500×g
• Quick, reproducible results for consistent workflows

Ergonomic Features

• Graduated PCV tubes for immediate volume-based quantitation
• Non-graduated tubes compatible with “Easy Read” Ruler for finer resolution
• Eliminates need for costly automated counters or fragile slides
• Removes subjective microscope-based counting
