- T-slot design allows apparatus to be easily reconfigured and equipment added.
- Corrosion resistant materials used throughout
The 800A/805A were designed to enable physiology researchers to easily test intact muscle tissue with an ASI muscle lever system. The 800A and 805A in vitro test systems were designed for use with 300C and 305C muscle lever systems respectively.
The 800A and 805A consist of a vertical mounting plate, legs, motor mount, tissue bath, vertical translation stage for the bath, lower tissue clamp, electrode holder and a vertical translation stage for the lower tissue clamp. Also included are an oxygenating bubbler, tube clamp, motor cable clamp, screws to mount the motor to the motor mounting plate and a set of metric Allen keys.
All parts are manufactured from corrosion resistant materials (anodized aluminum, stainless steel and Delrin). The vertical mounting plate is an extrusion with vertical Tee slots that allow additional equipment to be mounted on the plate. The Tee slots permit simple repositioning of the apparatus on the mounting plate. This is accomplished by simply loosening a screw and sliding the apparatus to the new position. Extra Tee nuts and screws can be purchased from ASI.
The 800A and 805A provide flexibility to the researcher by including a vertical translation stage for the tissue bath that allows the bath to be easily raised or lowered for access to the tissue. The position of the bath with respect to the lever arm and with respect to the lower tissue clamp can be adjusted with stops located on the vertical mounting plate.
The location of the lower tissue clamp can be adjusted through a wide range by using the vertical translation stage connected to the lower tissue clamp assembly. This stage features dual fine/coarse controls that permit large movements during tissue installation and then fine position adjustment that allows the resting tension or resting length of the muscle tissue to be set.
The position of the electrode clamp can also be adjusted over a wide vertical range by simply loosening the clamp screw and repositioning the electrode clamp anywhere along the length of the lower tissue clamp support tube.
