KD Scientific Gemini 88 Dual Rate Infusion/Withdrawal Syringe Pump

KD Scientific offers the NEW Gemini 88 Plus Dual Rate Syringe Pump.This unique pump is really two pumps in one, by providing two independent pumping channels linked through hardware and software.The dual rate syringe pump can infuse simultaneously at different rates, or infuse with one syringe and withdraw with the other.When combined with a valve box, it provides the continuous delivery of a peristaltic or piston pump with the accuracy, absence of pulsation and low flow rates of a syringe pump. This functionality allows continuous infusion or withdrawal, 24 hours a day, 365 days a year with the accuracy and low flow of every KD Scientific syringe pump.

  • Two separate syringe pumps in one instrument
  • Large touch screen display allows quick and easy setup
  • High or low pressure operation
  • Compatible with a wide variety of syringes
  • Continuous fluid delivery
  • TTL, USB & RS-232 Communication

 

Graphical User Interface

The intuitive Gemini 88 Plus graphical user interface controlled with a large 7” LCD colour touch-screen display allows quick and easy set-up. The display run screen presents the user with all key dispensing parameters in real time. Syringe tables containing all major syringe manufacturers allow simple selection of any compatible syringe size. Audible Alarms, Adjustable Force and Screen Lock are all features that are available with a touch of the screen.

Connectivity & Communication

The Gemini 88 Plus comes standard with USB and RS-232 for PC communication and RS-485 for pump-to-pump
communication. An entire suite of ASCII commands is available to control the pump remotely with a PC. The
pump contains a footswitch input and digital input/output for each independent pumping channel.

Features, Benefits & Applications

The Gemini 88 Plus Dual Rate Syringe Pump opens up whole new pumping possibilities.
Three operating conditions named Independent, Reciprocating and Twin are available as standard features to
satisfy various applications in life science and industrial settings.

  • Continuous injection for long-term toxicology testing
  • The injection of dyes, perfumes and flavouring in industrial applications
  • Applications with liquids or viscous materials in micro-manufacturing
  • Continuous injections of reactants into reactor vessels
  • Simultaneous samplings from two sites

Various applications can benefit from the three operating conditions. All three conditions come with the Gemini 88 Plus.
No additional upgrades are required.

 

Independent Condition

Independent Condition allows the Gemini 88 Plus to operate as two separate syringe pumps named P1 and P2. Each syringe will operate independently with different syringe types, sizes, force, or target (volume or time, mode dependent).

Reciprocating Condition

In Reciprocating Condition, both syringe channels move in opposite directions at the same rate using the same syringe size and
type. When combined with a valve box, the Reciprocating Condition can provide the continuous fluidic delivery of a peristaltic
pump with the accurate, pulseless, low flow rates provided by a syringe pump.

Twin Condition

Twin Condition allows both syringes to operate in the same mode using the exact same syringe type, syringe size, force, target (volume or time) and flow rate settings. The pump also allows the user to combine both flows for higher speed and
volume infusion applications.
