Temperature-regulating Manifolds
Temperature-regulating manifolds (thermoelectric or recirculated water type) are available for the LPMR-series modified Robbins devices and other TACT Tools. Thermoelectric modules consist of a resistive array or a Peltier heat pump embedded in an anodized aluminum ingot machined to accept one or two specific biofilm devices. A low-voltage, high-current DC circuit under microprocessor control drives the heat pump or resistive array. Solid-state sensors embedded in the aluminum ingot provide feedback to the microprocessor, which functions as a proportional integrating controller. The desired temperature is programmed by means of a front panel keypad, indexing the setpoint in one-degree increments up or down. The setpoint is displayed on an LCD display, along with the actual temperature and the power consumption of the driver circuit.
We also produce liquid-regulated thermal manifolds for use in laboratories that have a recirculating water bath available. These consist of an anodized aluminum ingot as above, machined with a serpentine pattern for fluid flow. In these manifolds temperature is regulated and maintained by the recirculating water bath.

Chemostat Culture Systems
The Tyler Research 500ml chemostat is intended for the growth and maintenance of bacterial cultures for input into laboratory-scale TACT Tools and other modified Robbins device systems. The device consists of a glass vessel (with or without water jacket), a Teflon and glass rotor assembly, and a polysulfone ported cover. There are 5 locking ports on the cover, each of which is capable of accepting and sealing a cylindrical object (plug, probe, tube or thermometer, for example) with diameters of 6mm or ¼”. The cover holds two O-rings to provide a sterile seal with the glass reservoir. Agitation and circulation is provided by indirect drive of the rotor via placement on a standard magnetic stirrer.
A 500ml chemostat is available in a standard (single wall) or water-jacketed (double wall) format for culturing bacteria prior to their infusion into modified Robbins devices.
