STREX Mechanical Cell Strain Instruments

STREX high-performance mechanical cell strain instruments and cell culture chambers allow researchers to explore the impact of mechanical cell strain on cells in culture. Mechanical stress applied to the cells better simulates a natural dynamic physiological environment.

Use STREX to investigate:

  • Bone, muscle, cartilage, ligaments & tendons
  • Cardiovascular system
  • Cell adhesion, division, growth & cytoskeletal rearrangement
  • Stem cell proliferation & differentiation

Benchtop Stretch Instruments

Automated instruments designed to hold multiple strain chambers with precise uniaxial mechanical strain. The robust and easy to use design ensures that cells grow over long periods of time with regular cyclic stretching. These units allow you to control the frequency and degree of the strain to produce 64 unique strain settings.

Specifications

  • Stretch multiple chambers simultaneously
  • Chamber size 4 cm2 (STB-140-04) or 10 cm2 (STB-140-10)
  • Unidirectional stretch patterns
  • Instrument includes standard patterns or design custom patterns

ShellPa Mechanical Cell Strain Instrument from Menicon Life Science

The mechanical stresses are closely related to cell proliferation and differentiation or tissue degeneration and development. Additionally, disease processes such as osteoporosis, cancer metastasis, skin disorders and muscle degeneration share a loss of tissue structure, integrity and mechanical transduction. ShellPa, the mechanical cell stretch system from Menicon Life Science, is an instrument for cell culturing that has been developed to replicate a dynamic environment inside the human body. This system is pneumatically driven by an air compressor. It is expected that cell culturing under the mechanical stress provided by this system can bring more biologically and physiologically realistic cell responses compared to a conventional static cell culturing without mechanical stress.

Features:

  • The stretch frequency and stretch ratio (stretch pattern) are easily controllable.
  • Stretch chambers are made with silicone (polydimethylsiloxane, or PDMS) and can be used with this system after being coated (e.g. fibronectin).
  • Lightweight and compact
  • Fits in standard laboratory incubator
  • Stretch frequency: 1-120 cycle(s)/min
  • Stretch ratio: 2, 4, 5, 6, 8, 10, 12, 15 and 20%
  • Use up to 6 stretch chamber simultaneously
  • Removable stretch chambers holder
  • Controller clearly indicates the accumulated operation time
