Cell Stretch Systems

• Ideal for piloting a stretch experiment to develop cell adhesion and stretch protocols before automating stretch.
• Single chamber capacity.
• Stretch cells manually at 0.8 mm per turn of the threaded manual stretch bolt.
• Apply uniaxial stretch with ST-0040 or ST-0100, or uni- or biaxial stretch with ST-0042.
• Compatible with microscope imaging after stretch. Simply affix the stretch chamber with the device upside-down to allow the chamber membrane to lie flat on your microscope stage. 
• Compatible with standard incubators.
• Former model #: STB-100-04 (ST-0040), STB-100-10 (ST-0100)

• Apply mechanical stress loads to in vitro cells in monolayer or culture.
• Eight (ST-1440) or six (ST-1400) parallel chambers capacity for easy comparison between different variables, conditions, or phenotypes.
  
  
  
  
• Apply automated cyclic (sine or square wave) uniaxial stretch with 64 preprogrammed patterns to get the project started right away.
• Stretch between 2% and 20% of relaxed chamber length to model in vivo conditions.
• A water pump cools the step motors for continuous, long-term stretch over the course of days or weeks.
• The stretch unit is compatible with standard incubators. Leave the control unit on the benchtop for remote operation.
• Transfer the stretch chamber mounting bracket to a clean bench for aseptic operations and an easier workflow.
• Former model #: STB-1400-04 (ST-1440), STB-1400-10 (ST-1400)

 Stretch cells effortlessly inside your incubator using PDMS chambers designed for monolayers, cultured cells, spheroids, and tissue. With 64 built-in stretch patterns, you can skip the hassle of programming from scratch and focus on your research.

Cyclic (sine wave) stretching

Stretch-and-hold (square wave) stretching

Static stretching

• Apply mechanical stress loads to in vitro cells in monolayer or culture while imaging with your microscope.
• Single chamber capacity.
• Apply automated cyclic, single, or incremental uniaxial stretch with 100 preprogrammed patterns to get the project started right away.
• Stretch between 2% and 20% of relaxed chamber length to model in vivo conditions.
• Stretch for up to 20 minutes at a time, imaging at up to a recommended 40x magnification (or at 60x or 100x with a water-immersion lens).
• Compatible with Nikon and Olympus microscopes, or with Zeiss, Leica, and other brands using a stage adapter.
• Compatible with standard incubators and incubator-mounted microscopes.

SP-1500 Cover Glass Applicator
The included SP-1500 Cover Glass Stage applies 2 glass slides to the bottom of the chamber to minimize friction when stretching and maintain the rigidity of the chambers. A 200 µm gap is
created between the slides where cells under observation are seeded.

The chamber is then positioned in the ST-1500 with pins that pierce the thick sides of the chamber from the top (glass slides are on the bottom).

Cells need to be observed within minutes of removing from the incubator to maintain activity before they enter a dormant state.

• Stress in vitro cultured or monolayer cells mechanically while imaging with your microscope.

• Single chamber capacity.

• Apply automated cyclic or single uni- or biaxial stretch and compression with 80 preprogrammed patterns to get the project started right away.

• Stretch biaxially between 2% and 20% of relaxed chamber length, or up to 30% uniaxially, to model in vivo conditions.

• Stretch for up to 20 minutes at a time, imaging at up to a recommended 40x magnification (or at 60x or 100x with a water-immersion lens).

• Compatible with Nikon and Olympus microscopes, or with Zeiss, Leica, and other brands using a stage adapter.

• Compatible with standard incubators and incubator -mounted microscopes.

• Former model #: STB-190-XY
