TPP Syringe Filters, designed by scientists for scientists, improves the ease and rate of filtering small Vols of tissue culture media, aqueous solutions, additives, buffers and water.

Key Features:

• Designed for high flow rate of media or aqueous solutions
• 3 to 5 times faster than standard syringe filters
• Typical starting flow rate at 25°C for water at 2bar (~29psi) is 175mL/min
• 0.22µm or µm PES membrane
• Low protein binding
• Larger filter surface
• Low dead Vol Additional specifications
• Higher operating pressure
• Burst pressure 10bar (~145psi)
• Bubble point 3.7bar (~53psi)

• Standard luer-lock connection

• Housing diameter size 33 mm, Syringe filter rests perfectly on a 50mL centrifuge tube

• Gamma-sterilized, DNAse/RNAse-Free, and pyrogen-Free
• Individually wrapped in peel-off plastic wrapper in convenient card box dispenser

Typical applications:

Sterile filtration of protein solutions, tissue culture media, additives, buffers, and water.

Solutions can be filtered fast due to:

• Large filter surface area, that is increasing the flow rate and throuput
• High operating pressure: a maximum housing pressure of 10 bar (~145 psi).

Bi-directional
The syringe filter units bi-directional support of the filter membrane enables users to filter aqueous solutions in either direction (only ONE direction per use):

• Forward (from the syringe into the container)
• Backward (from the container into the syringe)

The filter unit removes micro organisms, particles, precipitates, and undissolved powders larger than 0.22 micron or 0.45 micron, depending on filter used.

TPP Cell Scrapers have a pivoting head that enables the blade angle to be changed effortlessly with a slight twist of the fingers while still in contact with the surface being scraped. This allows for easy and thorough cell retrieval from vessels of all shapes and sizes without having to constantly re-position the scraper or culture vessel.  The TPP exclusive raised knobs on the handle allow for a slip free and secure grip when wearing gloves.

Key features

• Scraper blade
• pivots for easy maneuvering without constant lifting and re-positioning
• Made from a specially soft and flexible polyethylene material
• maintains great contact but won't damage cells

• Small raised knobs on handle for a secure grip
• Scraper sizes provide superior access to all edges of culture vessels of all shapes and sizes
• Allows for 100%  cell retrieval

• Sterile, individually packaged in a paper/plastic peel-off wrapper
• Packed in stackable and user friendly TPP boxes
• Lint-free blistering packaging

We are sorry some of these products have been discontinued.
GREAT NEWS, we have replacements & TPP is working on new pipettes. 

TPP Serologicals were uniquely designed to be shorter and more ergonomic to permit access into vessels of all shapes and sizes, while providing the end user significant advantages in liquid handing and overall usage. The single piece construction of TPP serologicals 1-25mLs eliminate media drip post-aspiration.

Key features:
Standard serological pipettes: TPP 1mL, 2mL, 5mL, 10mL & 25mL Serologicals

• Accurate Vol 1 - 25 ml
• Highly visible, bidirectional (ascending, descending), and over-Vol graduations
• Single piece construction prevents "pipette drip"
• Smooth interiors, prevent cell hang-up or clumping inside the pipette
• Shorter length reduces arm/back strain of end user
• Excellent optical transparency
• Color coded cotton plugs and dispenser boxes for easy identification

• (25mL - Red, 10mL - Orange,  5mL - Blue, 2mL - Green, 1mL - Yellow)

Serological pipettes with reservoir: TPP 25/40mL & 50/70mL Serologicals

• Manufactured with highest grade PS, extremely break resistant and robust
• Reservoir offers large capacity Vols in a compact, ergonomic design. It augments the total Vol capacity without adding proportionate length to the pipette
• Slender and short form enables ergonomic working conditions in the sterile hood
• Small outside diameter of the tube at the tip results in an excellent accessibility of the large pipettes even in small tissue culture flasks

• 40mL and 70mL max Vols enable larger media aspiration

• Optimized form of the mouthpiece preserves the rubber of the pipette aid

The serological pipettes with reservoir from TPP are molded with highest grade polystyrene. They fit in all commercially available pipette aids with rubber inserts.

Convenient Packaging Design

• Individually wrapped in lint free paper / plastic blister
• Color coded, convenient stackable TPP dispenser box
• Single dispense or convenient opening for dispensing larger number of pipettes

Quality Assurance for all TPP Serologicals:

TPP's Packed Cell Vol (PCV) tube enables a quick and reproducible method of cell counting based on cell Vol. A quick centrifuge of the cell suspension pipetted into a PCV tube reveals a packed cell pellet in the PCV capillary, which can be easily read with the aid of an Easy read ruler. This non-subjective method is superior to old-fashioned and labor intensive hemacytometer based counting.

Functional Features:

• Cell suspension sample can be directly quantitated without dilution
• Multiple samples can be assayed simultaneously
• Load and spin as many PCV tubes as your centrifuge rotor holds
• Quick and reproducible
• Cells can be spun down in 1 minute at 2500xg

Ergonomic Features:

• Reproducible measurements
• Graduated capillary model offers immediate quantitation
• For finer quantitation: The Easy Read Ruler  is used with non-graduated PCV tubes
• Eliminates expensive automated counters / fragile slides
• Avoids subjective microscope counting

Quality Assurance:

• Gamma-sterilized, DNAse/RNAse-Free, and pyrogen-Free
• Individually wrapped in peel-off plastic wrapper

Protocol Example:

• Uniformly mix cell suspension collected from TPP  flask/dish/bioreactor
• Pipet 1000µL of cell suspension into a PCV tube
• Spin multiple samples for 1 minute at 2500xg in a standard microcentrifuge
• Record pellet Vol and compare to pre-generated standard curve of cell numbers to packed cell Vol.
• Standard curve needs to be set up only once per cell line
• Pipet pre-determined cell suspension Vols (dilutions) into a hemacytometer
• Calculate and record the number of live cells for each concentration
• Pipet the identical Vols into the PCV tube, centrifuge and record the numeric in the capillary that corresponds to pellet Vol
• Plot the hemacytometer readings vs. the PCV readings for each Vol
• This Standard Curve doesn't need to be redone for the same cell line and moving forward the cell suspension harvested from TPP flasks/dishes/plates only need to be centrifuged in PCV tubes and assayed for cell pellet measurements

High density of cells

• With a very high density of the cells, the samples must not be diluted. You might simply reduce the sample Vol. Samples from the same series should be treated accordingly. 
• For bacteria measurement the parameters have to be adjusted, for example higher g-force, smaller Vol, etc.
• Micro centrifuges with swing-out rotors are preferable.

• Transparent, nontoxic and inert
• Precise, uniform drop size
• Shatter-proof and unbreakable
• Can be used with LN2 (-196° C)
• Heat Sealable

These unbreakable, one-piece pipettes eliminate contaminated rubber bulbs, broken glass and exposure to infectious materials. They are made of ultra-clear, low density polyethylene (LDPE) and are ideal for microbiology, blood banking, hematology, immunology, and urinalysis. Sterile pipettes are excellent for tissue culture application. Their low-affinity surface reduces sample, cell or protein loss.
 
Whether you make your selection based on length, build draw, pipette capacity or number of drops per ml, one of these ten designs is likely to be suitable for your application. Some have ultra-fine extended tips (P4113, P4117,P4121, P4122, P4133) that allow for extremely precise dispensing and access into the narrowest vessels. They can also be heat sealed for airtight sample storage. Their uniform drop size can be used for reproducible spotting of gels & TLC plates, and for dispensing into test plates, ID strips, PCR tubes or 96 well plates.
