The 802D permeabilized fiber test apparatus was designed to enable physiology researchers to easily test permeabilized fibers with an ASI model 315C or 322C high-speed length controller and an ASI series 400A force transducer.

The apparatus consists of a temperature controlled 8-well bath plate, indexing system, microprocessor based controller, and XYZ micrometer translation stages that include mounts for a lever system and force transducer. All parts are manufactured from corrosion resistant materials (anodized aluminum, stainless steel and Delrin).

Simple Push Button Control
The 802D works by moving the bath plate relative to the fiber. The fiber is clamped between the output tube of the force transducer and the lever arm of the high-speed length controller. In operation the researcher selects the desired bath by either clicking a button on the 802D PC Software, or by running a protocol from our ASI600A software. When a new bath is selected the bath moves downwards and then indexes to the desired bath. When it arrives at the new position the plate automatically rises to the operating position. The on-screen software includes a digital display that shows the current bath position. Bath-to-bath index time is approximately 1.2 seconds. This includes the time required to lower the bath, move to the new position and then raise it. Indexing, bath-to-bath, positional accuracy is better than +/- 0.05mm.

Eight Well Stainless Steel Bath Plate
The bath plate is manufactured from aluminum which is coated with Tufram to prevent any corrosion. The plate has eight baths machined in its upper surface. This number allows for test protocols involving multiple solutions without the need to empty and re-fill baths. All baths have a glass bottom to allow for microscope observation of the fiber or laser-based sarcomere length measurement. Bath 1 is larger than the rest as it was designed to be the bath in which the fiber is attached to the force transducer and length controller. Bath 1 also includes right angle prisms on both sides of the bath to allow the fiber to be viewed from the side as well as from the top.

Includes Mounts and XYZ Translation Stages
Both the high-speed length controller and the force transducer are mounted on XYZ micrometer translation stages to allow them to be positioned relative to the bath plate. 

Software Programmable Motion Sequencer
The 802D Bath Controller features a software programmable motion control sequencer. This sequencer allows the researcher to automate the movement of the bath plate.
