The Pump 11 Elite Series of syringe pumps expands its capabilities to satisfy your experimental requirements. These compact syringe pumps carry on the tradition as the premiere workhorse infusion pump, offering unparalleled ease of use with a high resolution touch screen with intuitive icon interface. The Pump 11 Elite Series allows you to create, save and run simple to complex methods without a PC. 

These syringe pumps have a new mechanism that includes a tight gripping, more secure syringe clamp for syringes ranging from 0.5ul to 60ml (single syringe) and 0.5ul to 10 ml (dual syringe). The Pump 11 Elite Series offers enhanced flow performance with high accuracy and smooth flow from 1.28 pl/min to 88.28 ml/min. 

The Pump 11 Elite Series is available in Infusion Only or Infusion/Withdrawal Programmable Models with single or dual syringe racks. These pumps have advanced connectivity with a USB serial port for computer control, RS-485 (or optional RJ-ll) ports for daisy chaining pumps and Digital I/O for remote control. 

Since 1901 Harvard Apparatus has been supporting bioresearch fluidics requirements with the culmination being the introduction of the first commercial syringe pump for bioresearch in 1956. Since 1956, over 70,000 satisfied syringe pump users around the world have made Harvard Apparatus syringe pumps the worlds #1 choice. 

The Pump 11 Elite Series is a family of accurate, low flow syringe pumps designed for use in applications including: mass spec calibration, drug and nutritional studies, reactor dosing, and electrospinning. 

Advanced Programming Features: 
? Constant Rate 
? Ramp 
? Gradients 
? % composition (up to two solvents) 
? Autofill 
? I/O — dedicated and user defined I/O 

Easy-to-Use Interface 
The Pump 11 Elite color LCD touch screen with graphic user interface is divided into three basic areas: Operations Display, Message Area, and Navigation. This configuration allows you to easily move through all menu selections and data entry by gently touching the onscreen buttons with a finger or the tip of a soft, non-sharp object such as a pencil eraser. 

The Method Main or Quick Start screens are the primary "home" for the pumps. From those screens you can access all the commands needed to operate the Pump 11 Elite, as well as access the main system settings. 

The Message Area of the touch screen is used to display helpful instructions for the currently displayed screen. It is also used to display error or warning messages to indicate problem conditions in a Method or error conditions during pump operation. 

The software is organized into three main navigational branches, the quick start Methods, user-defined Methods, and system settings. You can control operations directly with the touch screen or remoy from an independent computer or device via the external I/O interface. 

Program Description 
To operate the Pump 11 Elite, the user defines all the required parameters for infusing or withdrawing liquids through a Pump Control Method. The basic operation is a simple 4-step procedure: 

1. Select a method 
2. Enter operating parameters 
3. Preview your method 
4. Run your method 

Advanced GLP Documentation Features: 
? Download experimental parameter information to PC 
? Alpha/numeric keypad for method naming 

Pump Models 
The 11 Elite Syringe Pumps are available in two configurations designed for different operating environments and varying degrees of operational flexibility. 

1. Infusion Only (single and dual syringe models): These models support infusion operations at user-defined flow rates and with selectable target volume or time values to control the total infusion volume. The Infusion Only models do not include programmable, user-defined methods. 

2. Infusion/Withdrawal Programmable (single and dual syringe models): The models support both infusion and withdrawal operations and can use both simplified pumping profiles or the more advanced pumping profiles and I/O settings that permit interactions with external devices. In addition to supporting all of the advanced programming tools available on the Pump 11 Elite, this model also allows users to create and store up to two user-defined methods of 50 steps each on the pump. 

Accessories 
A full range of accessories are compatible with the Pump 11 Elite including syringe heaters, in-line heaters and coolers, nanofluidic circuits, connectors, tubing, syringes and more.
