The new SI-H Horizontal Tissue/Organ Bath system (SI-HTB) combines the ease of use and productivity of a traditional vertical organ bath with the more advantageous features of single tissue physiology platforms.

  • Two channel system for increased productivity, easily expanded to add channels
  • Fully independent heating and fluid control for each channel
  • Low profile/small footprint
  • Variable volume, chemically inert teflon bath with shape configurations from variable to fixed 1.5–10mL
  • Modular, space-saving, blade-style electronics (Control up to 4 channels with the electronics in one chassis)
  • Large variety of force transducers covering mN–N forces, all with lifetime warranty
  • Can be combined with automated fluid control systems
  • Add a linear motor and controller (SI-MOTTEST) to perform mechanical, electrophysiological and optical techniques, inculding isometric (standard), isotonic, eccentric and auxotonic
  • Add a photometer for Calcium, NOx, ROS
  • Add an electrometer like the WPI Duo773 or Electro705
  • COMING SOON­—Add a 3-channel, multi-purpose biofluorimeter for tissue Fluorescence (calcium, NO)

Multiple Bath Options

The SI-HTB system breaks through the (large) volume limitations of  the traditional organ bath, allowing volumes as low as 500µL in an inert, teflon-based bath.
The bath design allows multiple shape options for thick, long, flat and thin tissue. When pharmaceuticals are available in precious, small amounts, you will appreciate this standard feature. A wide range of transducers and tissue mounting supports complement this freedom of tissue shape, volume and size.
Low Profile

The low profile and small footprint of the bath system, combined with the modular, space-saving, chassis-mounted design of the electronics, reduces the bench space requirement up to 4-fold when compared with standard 4-channel organ baths.
Versatile System

The SI-HTB combines advanced physiological techniques with the throughput needed in pharmacological assays in one flexible platform. Upgrades to four or more channels are easy and economical.

The motor option (SI-MOTTEST) turns your system into a tissue work-out station with isotonic, auxotonic and eccentric force measurement capabilities. Nearly all established myo-mechnical tests from stretch-release to work-loops and muscle fatique are now possible in a single organ bath system. Some of these procedures require a length change solution (software/hardware) like WPI’s MDAC package.
Future is Now

The solid horizontal tissue bath design is ideal for combination with electrophysiology on the same platform. Intracellular measurements can share the stable solid base of the bath system.

WPI’s new fiber-optic based, multi-channel biofluorimeter, which is scheduled for release in the fourth quarter of 2012, will allow for tissue fluorescence measurements (calcium, NO, ROS) on the SI-HTB platform.  

Now, you can design a system to meet your needs and budget. And, it is fully upgradeable in the future.
