The NE-4000 SyringeTWO is a two-channel programmable syringe pump for a wide range of applications: the SyringeTWO can generate flow rates typically from 23.9 nL/min to 100.3 mL/min.
The SyringeTWO pump is fully programmable standalone or through a computer.
General
The SyringeTWO is a dual channel syringe pump for general microfluidic applications, covering a wide range of flows from less than 1 nL/min up to 125 mL/min. This pump can hold 2 syringes up to 60 mL (or a 140 mL syringe filled up to 120 mL). Built for automation, it contains numerous preset protocols, from simple infusion and dispensing to complex experiments. You can program up to 41 different steps:
- Change infusion/withdrawal rate
- Set dispensing volumes
- Insert pauses
- Control and respond to external signals through RS-232 and TTL logic control interfaces
The pump works standalone or can be programmed through a computer using the SyringPumpPro software. You can even daisy-chain up to 100 pumps via RS-232 and control them through a computer!
The main specifications for this version of the pump are:
- From 23.93 nL/min (with a 1 mL syringe) to 100.3 mL/min (with a 60 mL syringe), higher flow rates can be achieved using a 140 mL syringe.
- Accuracy of +/- 1%.
- Linear force of 6.8 kg (15 lbs) at top speed and about 45.4 kg (100 lbs) at slow speeds

In withdrawal mode, certain glass syringe barrel plungers may not be securely held by the pump's standard pusher block. For 50 and 100 mL glass syringes, the use of the New Era Pusher Block for 50 & 100 mL Glass Syringes is required.

Infusion and withdrawal
Dispense a set volume
Syringe purge mode will infuse or refill syringe at top speed to purge air from the line or to fill the syringe
Power failure mode restores all parameters on power up, even in case of a power failure while pumping
Pumping rate and direction can be changed while pumping
Stall detection stops the pump when the motor's operation is impeded

Pump programming
General
- One-click program upload from "Pumping Program Generator" spreadsheet
- Program up to 340 phases
- Data entry from keypad or computer
- Pumping programs can be uploaded/downloaded to/from the computer
- Pre-programmable dispensing volumes (each volume can be different)
- Pumping rates and direction are automatically changeable
- Time delays between dispenses can be set
- Automatically pause the program and wait for the user to continue the dispense
- The pump rate can be synchronized with other instruments (pumps, sensors, etc...)
- Send logic signals to other equipment. Change pumping rates in reaction to a sensor
- Program the audible alarm to beep at any time to alert the operator
Bi-directional RS-232 interface
- Network up to 100 pumps from a single communications port on a computer. Baud rates up to 19200.
- Free terminal emulator program allows communications with the syringe pump.
- Directly control one or more pumps from a computer, including setting the pumping rate, direction, and volume. Set the operational and setup configurations. Also, the TTL interface can be queried and the programmable output set.
- Each pump in the network can be individually controlled and monitored using a computer. Or, the computer can download a new pumping program to each pump, and automatically reconfigure the dispensing system for a new job.
- Downloading control programs to the pump would unload the computer overhead to the pump. computer resources could then be used elsewhere while the pumps operate independently.
- 2 modes of communication: Basic and Safe
-
Basic: Basic master-slave interface. Easy to implement. Can communicate from any terminal emulator.
-
Safe: A reliable interface for a real-world environment.
- High-quality interface which detects communication errors via a 16-bit CCITT CRC.
- The pump will automatically transmit an alarm packet when a pump alarm occurs. For instance, if the pump stalls or resets, a message is immediately sent to the computer.
- A configurable communications time-out will stop the pump and alarm if the communications link is broken.
- Packet inter-character time-out to recover packet synchronization after communication glitches.
- Software Developer friendly communications protocol.
- Consistent and well-defined communications packets.
- Constant start and end characters.
- Packets structured to be easily parsed
TTL Logic Contol Interface
- Control the pump from a foot switch or timer.
- Output signals can be used to switch a valve from an output to an input reservoir.
- Keypad Lockout: Prevent unauthorized or accidental changes to the settings by requiring a "Lockout Disable" key to be inserted to change settings.
- Pumping direction control
- Programmable output signal
- Programmable responses to input signals
- Configurable start and stop trigger:
- Start or stop the pump on each contact closure to the ground. For example, a foot switch.
- Start the pump on closure to ground and stop the pump on opening the connection. For example, a timer relay that starts the pump whenever closed and stops the pump whenever open.
- Only start the pump on each contact closure to ground. For example, a laboratory animal trained to press a lever can receive a drug dosage from the pump and the pump will not stop or deliver another dosage until it is permitted by the pumping program entered by the user
- Configurable trigger input:
- Edge trigger: Starts or stops the pump, such as from a foot switch
- Level trigger: Start or stops the pump, such as from a timer or relay control
- Start only trigger: Edge trigger will only start the pump, such as from a lab animal trained to press a lever to receive a dosage.
