Base Unit:

Compact, all componenting integrated into a single housing
Heating block (with cooling) for temperature control
Top drive motor with mechanical sliprings seal, located behind the vessel for easier access to the top plate
Easy handling of single jacket glass vesel - light, cheap, replacement, no connections
Performance similar to heater pads but no fitting after autoclaving
Removable, autoclavable pump heads (minimum of 2, maximum of 4)
One or two (cell culture version) rotameters for gas supply

Control:

The direct digital control (DDC) system used in Minifors is a modern and reliable micro-processor based system used in INFORS HT shakers and bioreactors. The splashproof operating panel is integrated into the base unit and allows easy setting of key parameter values such as set points along with calibration and various control options. Multiple LED’s and icons display information.

Standard Measuring and Control Parameters:

Stirrer speed
Temperature
pH (with CO₂ valve on cell versions)
pO₂ (option on standard bacterial version)
Antifoam/Level (option)
Oxygen supplementation (option)
Feed (option)

Autoclavable Vessels:

The vessels consist of borosilicate glass covered by a stainless steel top plate with an optimal arrangement of port fittings and inlets. An intermediate aspect ratio of 2.5:1 is used to allow use for both bacterial and cell culture applications. Vessels, bottles and pump heads are all supported in a special holder for easy handling when autoclaving. All vessels are round bottomed.

Minifors systems are supplied as packages:

Package 2.5 L TV bacterial
Package 5.0 L TV bacterial
Package 2.5 L TV cells
Package 2.5 L TV cells

Vessels are complete with a 3-way inlet, exit gas cooler, inoculation port, sample device and pH electrode for the bacterial units. The cell culture systems have O₂ and CO₂ gas inlets as standard. Reagent bottles and sampling device come complete with tubing pre-assembled. Inlet/outlet filters are pre-fitted. A tubing kit, some consumables and data logging software are common to all packages.
