stimulation Pt. electrodes, for various
types and sizes of tissues and organs, in baths as small as 2ml.

system.
Much
lower system ($1K to $3K less for a 4-ch.) & drug costs than competitions.
Suitable
for studies of vascular rings (as small as 200¦Ìm), smooth/skeletal
tissue strips, cardiac tissues (atria, papillary,
sinus node, etc.) , and other isolated tissues and organs, on
one or multiple channels.
The EZ-Bath, the most
user friendly, cost-effective 4-channel tissue/organ bath systems
in the market. The state-of-the-art tissue bath is designed, based
on many years of combined experiences of various scientists. The EZ-Bath
can be used for studies of vascular or non-vascular tissues, skeletal
or smooth muscles, cardiac tissues/organs (e.g. atria, papillary,
sinus node), and other isolated biological tissue or organ preparations.
The EZ-Bath features
multiple innovative, proprietary functions that ease the tissue/organ
studies, efficiently producing more consistent data than any other
systems in the market. At the heart of the system is a versatile
mounting platform, on a mounting/control (M/C) bracket, for studying
distinct types and sizes of tissue or organ samples with ease. Among
the innovative functions are consistent point-of-force application,
reliable contractile signal transduction even for mini-contractile,
tissue tension micro-adjustment (as fine as 5 microns, see McPherson,
1992), modular tissue holders with or without embedded miniature
stimulation electrodes, and a multi-function adjustment feature.
The multi-function adjustment is designed to ease tissue mounting
and to accommodate different types and sizes of tissue preparations.
The micro-adjustment features, along with other innovations, improve
experimental consistency among different tissue channels and across
different experiments, which is essential for statistical data analyses
for bio-tissues/organs.
THE EZ-BATH ADVANTAGES:
Consistency, Versatility, Efficiency & Low Cost
1. The Proprietary,
High Consistency
Fixed Point-of-Force Application on Transducer & Solid Connection
onto Transducer For Reliable
Contractile Relay, in stead of competitors·¯
hanging hook or suture strings which can not sense
mini contractile;
2-D
Micro Adjustments for Presetting Tension and Easing Tissue Mounting
and Consistent Tissue
Positioning, in stead of competitors'1-D
rough adjustment;
Embedded
Mini Electrodes On Tissue Holders for Consistent Stimulation, in stead of competitors'
externally positioned electrodes or in-efficient electrodes fabricated
on glass chamber, introducing in-consistency among different tissue
channels or across experiments.
2. Versatility and Miniature Tissue
Holders
The EZ-Bath features
a series of proprietary, compact, exchangeable tissue mounting devices,
the MV, LV, TSS and TSC series tissue holders.
These holders relay accurately the mechanical tension, contractility,
and mobility of tissues under study, have embedded stimulation electrodes
that generate consistent stimulation actions, and are suitable,
in a single platform of exchangeable mounting, for studying various
bio-tissue preparations ranging from large/small/micro diameter
vessel rings (as small as 200µm in i.d.), skeletal muscle
spindles, smooth muscle strips, to atria and other organ/tissue
preparations, in our jacketed tissue baths as small 2ml in volume.

GlobalTown provides a very cost-effective
solution to the need for computerized data recording and transducer
amplification in a "one-box" solution, BRAMDA-4.
The 4-channel system, along with the powerful DAQChart
software, integrates bridge amplifiers, data acquisition system and
analysis, and is well suited for tissue/organ bath researches.
Alternatively, our portable, versatile data
acquisition systems,i-DAQ4
and i-DAQ8, can
be added as a separate system as needed for 4- or 8-channel EZ-Bath-4/8TBD
with one BRAM4 or 2xBRAM4 bridge amplifiers.
In either configuration, all you need
is a computer to start with highly efficient and consistent experiments,
recording and data analyses!
