Characteristics of Precision Injection Pump PHD22:

• Stable accuracy and reproducibility accuracy

• Flow rate

• Liquidity and universality

Forty years ago, Harvard Instruments improved the principle of guided screw and manufactured an injection pump. Since then, tens of thousands of Harvard pumps have earned the honor of reliable research partners in every important laboratory worldwide. The precision injection pump PHD22 series can provide you with slow flow rate, high precision, smooth liquid flow, programmable operation performance from the keyboard, and the precision injection pump PHD22 is easy to use.

High stability accuracy and repeatability accuracy

Precision injection pump PHD22 welded steel chassis, machined Derlin ™ Components, reinforced guide rods, and electronic devices can provide a stable accuracy of 0.35% and a reproducibility accuracy of 0.05%.

Low flow rate

The new micro stepper motor and control software of precision injection pump PHD22 provide low speed, which can be reduced to 0.0001 microliters per hour. It is still quiet, so it will not interfere with your experimental project.

versatility

Having a precision injection pump PHD22 can meet the needs of simple injection, infusion and aspiration, or programmable operation.

1. Only for injection: This injection pump is suitable for situations that require high precision and low flow rate, but do not require liquid suction or programming operations. Do you still need suction and programmable operation in the future? This injection pump, which is only used for injection, can be upgraded.

2. Injection/suction: The precision injection pump PHD22 injection/suction type injection pump has the same performance as the injection only model (mentioned above) and can also suction (re inject).

3. Programmable operation: The Harvard Precision Injection Pump PHD22 Programmable Operation Injection Pump has programming functions and is also very easy to use. This infusion pump can store four programs, each with 10 steps of operation. The program is stored in non-volatile memory. No other infusion pump can provide you with this level of control and flexibility. Programmable operational infusion pumps can also be programmed using Symphony, which is Harvard's Windows ™ Injection pump management software.

easy to use

The bright and easy to read dual row fluorescent display of precision injection pump PHD22 can be conveniently read from outside the laboratory. The target injection volume button makes it easy to deliver the pre-set injection volume. Even with only a small number of personnel participating in the work, the ergonomic "self-locking" release mechanism can make the work easier and there will never be a situation where the syringe forgets to lock. The numeric keypad utilizes the familiar "telephone" layout scheme.

upgrade

What we offer is an upgradable infusion pump. If you purchase an injection/aspiration precision injection pump PHD22 and later find that you need a programmable operation type, you can upgrade it. You can save a lot of money compared to buying a brand new infusion pump.

Programming instructions

The programming function of this precision injection pump PHD22 provides great programming capability for the experiment. In programming operation mode or when the infusion pump is activated by a signal from an external device, this precision infusion pump PHD22 can perform the following tasks at a preset time:

-Start or stop infusion

-Change the infusion direction (injection suction)

-Change the flow rate

-Deliver precise delivery volume and stop the machine

-Suspend work

-Increase or decrease the flow rate
