Custom Made Systems

The LOGAN SYSTEM 7000 is a fully automated test system for UPS Method 7 dissolution testing. This easy-to-operate (24-tubes per carrousel) Fully Automated Release Rate Test System utilizes the most modern technology and is designed to operate trouble-free and continuously.

In operation, the solid dosage samples (Transdermal patches, pellets, tablets, etc) are placed in the sample holders, after attaching the samples onto the sample holders, the shaft assembly automatically lines up with the test tubes down below. The carrousel temperature is controlled to a target set point ± .1ºC throughout the assembly, and the media is preheated in the test tubes.

The dip speed, dip time, hold time, drain time, and temperature are controlled by the unit’s microprocessor. The SYP-24 Syringe Pump takes samples at programmed time intervals and transfers them to the SCT-480 Sample Collector. At the end of each test cycle, the carrousal rotates 180º a new set of test tubes for the next test, the ATC-1200/MDS-1200 removes and raises the test tubes and refill the fresh media into the test tubes for the next test.

The Logan SYSTEM 7000 is fully automated, it can be controlled either by a stand alone system controller or by PC. The Logan SYSTEM 7000 is made of high quality metal which fully meets GLP requirements.

The LOGAN SYSTEM SUS-4000 is designed to test the release rate of suspension drug by flow-thru method, the DRY HEAT temperature controlling system ensures all test are performed at the programmed temperature. The membrane is mounted between the suspension cell (donor) and the Flow-Thru chamber (receptor). Temperature is maintained at 37°C by thermostatically controlled heater blocks, which surround the Suspension cells. Homogenous distribution is accomplished by the agitating motion of a Teflon-covered magnetic stirring bar, driven by an external magnet mounted on a timing motor.

 

This system saves valuable time by automating sample collection. The SYP Series Syringe Pump Module withdraws & measures pre-heated media volume from the DRY HEAT reservoir at selectable speeds (1, 2, 4, 8, 16, 24, or 32 ml/min). Media are pushed to the flow-thru chamber, mixed with the released suspension drug, and then remixed again in the delivering loop. The precise volume samples are then automatically delivered into HPLC vials or glass tubes.

 

The samples can be run as close loop or open loop. At each time interval samples are dispensed simultaneously into HPLC vials or glass tubes that are stored in the SCT Series Sample Collectors. For more information please contact Logan Instruments.
