SciLog - AccuTec

The ACCUTec TFF System is perfect for starting volumes of 50 ml to 5000 ml and has very low hold-up volumes. All wetted surfaces are low protein binding, chemically resistant materials.

Dimension:		5.75 Width x 6.25 Height x 11 Depth
Weight:		11 lbs.
Enclosure:		16 Ga, aluminum baked epoxy blue
ACCUTec Motor:		Variable speed, 8 RPM, 160 RPM, 450 RPM, 600RPM and 3400 RPM motors at 28 VDC, 3.8 Amps; optically encoded, servo - controlled.
Power:		110 / 220 VAC , 60 / 50 Hz, 75 Watts; double fused
Encoder:		120 lines per motor revolution.
Use Range:		4 to 40 C, 100% Humidity
Motor:		Choice of five (5) motors: 8, 160, 600, 450 and 3400 RPM at 30VDC, 3.8 Amperes, Variable Pump Speed, optically encoded servo-controlled motors.
I/O Ports: DB 15 (Back Panel)		RS-232 Serial port, DB15 connector, pin 2 (Transmit), pin 3 (Receive) & pin 5 (Ground) 4-20 mA input signal, DB 15 connector, pin 6 (Ground) & pin 13, with selection switch (back panel) at 4-20 mA 0-5VDC input signal, DB 15 connector, pin 6 (Ground) & pin 13, with selection switch (back panel) at 0-5VDC Pump Speed output signal, DB 15 connector, pulsed output between pins 7 (Ground) & pin 9, pulse rate is proportional to pump speed, ~5940 pulses/sec at 99% pump speed, ~3000 pulses/sec at 50% pump speed. Remote Start/Stop (Remote), closed contact closure (RUN), open contact closure (STOP) between pin 8 (Ground) & pin 15 of the DB 15 connector. This function is active when REMOTE has been selected from the front panel. Remote CW/CCW Motor Direction (Remote), closed contact closure (CCW), open contact closure (CW) between pin 7 (Ground) & pin 14. This function is active when the REMOTE mode has been selected from the front panel. Remote Start/Stop (Local), closed contact closure (RUN), open contact closure (STOP) between pin 8 (Ground) & pin 15 of the DB 15 connector. This function is active when the LOCAL mode has been selected from the front panel and the external contact closures (CC across pin 8 & 15) has been exercised, i.e. opening and closing the connected contact closures (CC). The front panel "RUN/STOP" key will be disabled at that point, however, the pump speed selection and the "CW/CCW" keys are still functional. The front panel "RUN/STOP" key function can be re-established by twice pressing the "LOCAL/REMOTE" key. NOTE: This operational mode should only be used when the ACCUTec pump is to be controlled (Stop/Start) by a SciLog Smart Pump, i.e. UltraTec or ChemTec. Foot Switch Start/Stop (Local), foot switch acts as an external contact closure, pump runs at the selected pump speed as long as the foot switch contact is closed, i.e. as long as you step on the foot switch. The pump stops when the foot switch contact is open.
Data Entry:		Membrane keyboard, 2 LED's with auditory feedback.

Compact, High-Precision ACCU peristaltic pump. Choice of three different motor sizes and multiple different tubing sizes can be used. Can add a second Tandem peristaltic head (piggy-back) to increase flow or eliminate pulsation.

Gentle Sample Processing — low-shear pumping action with Tandem™ peristaltic 4-roller pump head.

Aseptic Reservoir Vessel — Closed system creates vacuum in reservoir to draw process solution in as solution is being drawn out of the reservoir by the pump. Graduated 500 ml vessel made of FDA approved polysulfone is compatible with disinfectant, e.g.: isopropyl alcohol or sodium hydroxide. Seals do not make contact with your process solution. All fluid connections are 316 SS Female Luer with SS tubing lining all fluid channels; no exposed connector threads to contaminate. Optional 50 ml vessel is also available (#090-012).

Magnetic Stirrer — powerful, variable speed stirrer with LED in stainless steel enclosure. Use with either 50 ml or 500 ml graduated vessel.

Filter Holder — to hold/organize your Minimate or Pellicon filter cartridge and gauges.

Two Pressure Gauges — to monitor your feed and retentate pressure. If you require monitoring a third pressure, this can also be added. Stainless steel with Luer connectors.

Fittings/Tubing Start-up Kit — includes Male and Female Luer fittings, adapters, barbs, multiple plastic valves, stirrer magnet, tees, clamps reservoir air filters, tubing lengths.

Easy Clean-up and Maintenance — sent to you ready to use. Eliminate cleaning/ cross-contamination issues by using low-cost replacement components/tubing.
