Our Inoculating Loops and Needles are smooth and flexible to facilitate uniform, smooth streaking without damage to media/gel surfaces. The needles are straight and suitable for removal of single colony specimens. The loops are extra-smooth and constructed of polypropylene and rubber. Both the loops and needles are packed sterile in safe, tamper-proof, zip-seal resealable bags. Cross contamination due to improper sterilization is eliminated. They can be used under hoods without danger, are color coded for ease of size identification, and are extra long to reduce the risk of contamination. Certificate of conformity is available upon request.

Incu-Shaker™ - Stackable Shaking Incubator

Innovative features and outstanding cell growth properties make the TPP Tissue Culture Flasks the ideal choice for adherent cell culture in academia and industry.
 

• Cell growth surface

• Uniform flat growth surface promotes cell growth without clumping

• Growth area is opto-mechanically treated to promote cell adhesion and growth

• Lifted base
• Stable, slip-free stacking of multiple TPP flasks
• Allows for air flow between flasks to prevent condensation buildup
• Resulting in uniform temperature and CO2 distribution

• Crystal clear transparency for great microscopy images!

• Geometry of the neck reduces risk of media slop over

• Geometry of the neck guarantees total access of TPP pipettes, TPP scrappers and the TPP spatula. No dead corners = 100% cell retrieval.

• White and accurate Vol graduations for optic control of the filling Vol.

• Highly visible bilateral marking area

• Vented cap settings for "on" at 12 o'clock position and "off" at 3 o'clock position.

Additional Advantages

Flasks are available in either filter cap or vented cap:

The TPP Click

1. A click and the <> screw cap is in the <> aeration-position.
Visual control: the slightly raised rectangle is at 12 o'clock.
2. Turn <> screw cap clockwise 90° to close the flask gas-tight closed.
Visual control: the slightly raised rectangle is at 3 o'clock.

Filter Membrane in Filter Screw Cap
The filter screw caps feature a hydrophobic PTFE membrane with a pore size of 0.22 µm. This offers protection - as the hydrophobic characteristics repel any fluid - with optimal gas exchange at the same time.

Quality Assurance:

• Made from optically clear polystyrene for excellent viewing
• Sterile, packaged in gamma irradiated, sterile sleeves
• Certified DNAse/RNAse, nucleic acid, and pyrogen-free

Key Features:

• Vents provide airflow between stacked dishes for consistent growth conditions and prevention of Condensation
• Surface treatment of the growth area developed by TPP optimally enhances the proliferation of the cells
• Serrated grip ring on lid prevents accidental drops or lid lift offs in unsterile conditions.
• Double marking areas - yellow and frosted marking spots for easy labeling.
• Stacking ring on the lid and corresponding ridge on the base provide an extremely secure stacking feature
• Numeric "clock" markings (12, 3, 6, 9) for quick orientation during microscopy.
• Crystal clear clarity for great microscopy images.

Consistent Growth Conditions

• Air vents in the dish base allow airflow between stacked dishes for consistent air flow, temperature distribution, and prevention of condensation.
• Both features provide consistent growth conditions even when dishes are stacked.
• Outstanding flatness of surface promotes uniform cell growth without clumping.

Notable extra features

• Tissue culture dishes are designed for manual handling.
• The yellow inscription field on the lid and the frosted inscription field on the base enable a defined positioning of the lid.
• The side walls of the dish are not treated for tissue growth

Quality Assurance:

TPP TubeSpin® Bioreactors

Suspension cells ranging from immune cells to insect cells and microorganisms like E.coli to yeast can be cultured and centrifuged in TubeSpin® Bioreactors, eliminating the need for transferring before spinning down.
 
Features:

• working Vol 1-35mL
• easy to start small suspension cell cultures from frozen
• ergonomic use of bacterial and yeast cultures -- static and shaking
• conical bottom
• 0.2µM filter membrane
• Sterile gas exchange
• 5 openings
  • (A, B, C, D, E) of different size above the gas permeable, sterile PTFE filter of the screw cap
• Openings can be sealed to adjust gas exchange according to need
• Fits in standard 15ml centrifuge rotors
• Saves costs of culture start-ups in erlenmyer flasks and then transfer to conical tubes
• Culture and spin in a single tube

Advantages:

• Great gas exchange throughout the culture
• Defined ventilation
• Flexible working Vol with one type of tube
• No transfer stage - Spin down in the same tube
• Large-scale parallel experiments
• Rapid sampling following centrifugation, and the tube is disposable
• No internal stirring mechanism to damage cells or produce foam
• Less incubator or hood space needed; when compared to a T75
• Less plastic usage and less plastic waste
• Easier withdrawal from tube than a flask

Bacterial and Microbiological Cultures
TPP TubeSpin Bioreactors are ideally suited for the culture of bacteria, yeast, and other microbiological organisms in suspension.  The simple, disposable format offers convenience and time-savings over traditional glass vessels such as test tubes which must be washed and autoclaved before each use.  Both aerobic and anaerobic cultures can be grown by selectively covering the holes in the 0.22um filter cap.  1-35mL of culture can be grown in each TubeSpin bioreactor, offering the flexibility to perform mini plasmid preps, small-scale candidate screens, or other downstream applications.

The simple 50mL tube design contains no internal mixing or stirring mechanism which minimizes cell shearing and foam formation, and agitation is provided by shaking in a CO2 shaking incubator. In this manner, hundreds of cell cultivations can be performed quickly and efficiently in parallel.

Water loss
If small culture Vols are incubated over a longer period of time, the loss of water influences the growth of cells.

By the closure of one or several openings above the gas permeable and sterile PTFE membrane, this water loss can be minimized.

Sterile gas exchange is guaranteed through the 0.22 µm pore size PTFE filter membrane.
