How do you choose a pump that can run multiple syringes at once? This is a question that many labs and production teams ask. A reputable multichannel syringe pump manufacturer should respond with explicit specifications.

DK INFUSETEK makes the SP60-nA series in 2, 4, 6, and 8 channel models. Each pump has a rated stroke of 60 mm. All the channels may operate simultaneously. A microprocessor or computer controls the pump.

This guide discusses channel count, shared specifications, valves, and control. It also tells you what to inquire about before you purchase.

What Is a Multichannel Syringe Pump?

A multichannel syringe pump is a device that moves liquid via multiple syringes at the same time. One glass syringe in each channel. Liquid flows in and out of a rotary valve. One device may thus handle many liquid lines simultaneously. 

This design saves time and bench space. One unit replaces a line of single pumps. This makes it very suitable for labs and production lines. Typical tasks include automated pipetting, dispensing, and dilutions.

How Does One Controller Run Several Channels?

A computer or microprocessor transmits each command. The setup screen for the SP60-nA is absent. The steps are established by your program, and the pump follows them. This makes the industrial syringe pump an excellent choice for automated systems.

Inside a Multichannel Syringe Pump Manufacturer

Shanghai R&D With a Northern China Production Base

DK INFUSETEK has its head office and R&D center in Shanghai. Its production base is in northern China. The full company name is Duko Industrial Technology (Shanghai) Co., Ltd. You can learn more in the DK INFUSETEK company profile.

The company specializes in one field: handling microfluids. It creates, customizes, and manufactures devices for this field. It claims to deliver high-end items at a reasonable price.

Where Does the Multichannel Line Fit in the Range?

The company has five product groups. These are laboratory, continuous flow, modular, and industrial syringe pumps and accessories. Industrial groups may be divided into three types: OEM Syringe Pump, Multichannel Syringe Pump, and Dispensing/Dilution Pump.

This is useful for buyers. A multichannel syringe pump manufacturer that also makes OEM modules knows how pumps fit into other machines. See the full group on this multichannel syringe pump manufacturer page.

Two, Four, Six or Eight: How Many Channels Do You Need?

You need as many channels as the liquid lines you run at once. All SP60-nA models share the same core specs. Only the channel count and size change. This makes the choice easy.

SP60-nA Channel and Size Comparison

Only the first size number increases with additional channels. The last two are at 153 mm and 254 mm. So you just have to check for space on one side of your bench.

SP60-2A for Small Two-Channel Work

The SP60-2A is the smallest pump in the series. It still has every shared spec. The two-channel SP60-2A pump page has the full datasheet.

Two channels often work well for one sample and one reagent. They also suit early tests before a project grows.

SP60-4A for Four Liquid Lines

The SP60-4A is a 4 channel syringe pump. It suits jobs with four reagents or four samples at once. See the full specs on the SP60-4A rotary valve pump page.

SP60-6A When Four Channels Are Not Enough

The SP60-6A has six channels. Many buyers miss it because most searches jump from four to eight. But six channels may suit your work best. It is also smaller than the eight-channel model.

SP60-8A for the Most Channels

The SP60-8A is an 8 channel syringe pump. It is the largest pump in the series. It runs the most liquid lines from one unit. Its page also has videos on liquid transfer, setup and accuracy. Watch them on the SP60-8A eight-channel pump page.

Which Specs Are the Same on Every SP60-nA Model?

Every SP60-nA model has the same stroke, resolution, accuracy, syringe sizes and control. So a method that works on one model works on the others too.

Stroke, Resolution and Run Time

Rated stroke: 60 mm

Resolution: 6,000 steps per stroke (standard mode)

Running time per stroke: 1.45 s to 100 min

Here is what this means. A 60 mm stroke split into 6,000 steps gives 0.01 mm of movement per step.

How Accurate Is Each SP60-nA Pump?

The accuracy error is below 1.0%. The repeatability error is below 0.2%. Both results come from a full stroke with deionized water. Other liquids or shorter strokes may give different results. So test with your own liquid.

Syringe size and calibration also affect accuracy. Read the guide on syringe pump flow rate accuracy to learn more.

Glass Syringe Sizes From 50 μL to 10 mL

The pump works with eight syringe sizes. These are 50 μL, 100 μL, 250 μL, 500 μL, 1 mL, 2.5 mL, 5 mL and 10 mL. Each syringe has a high borosilicate glass barrel. The push rod is stainless steel, and its seal is PTFE.

The syringes work from -20℃ to 65℃. The pump itself works from 15℃ to 40℃. Keep the pump within this range.

Why Choose a Syringe Pump With Valve?

A syringe pump with valve can change the liquid path on its own. No one needs to move the tubes. The syringe pulls liquid from one port. Then the valve turns, and the syringe pushes liquid out another port.

The site calls each SP60-nA model a "Multi-channel Pump with Rotary Valve." It also lists a separate line with solenoid valves, from SP60-2B to SP60-8B.

Rotary Valve Specifications

How Does a Programmable Syringe Pump Work With Automation?

A programmable syringe pump takes commands from your own controller. All the logic stays in your system. The pump simply does the work.

RS232, RS485 and Up to 15 Pumps

The pump connects through RS232 or RS485. The speed is 9600 bps or 38400 bps. A BCD DIP switch can set up to 15 addresses. This means up to 15 SP60-nA pumps can connect at the same time.

The pump has two TTL inputs and three TTL outputs. These help it work in step with other devices. It needs a DC24V ±10% power supply, with a 5 A peak.

Lost-Step Checks and Planned Care

A photoelectric sensor checks for lost steps. You can set the speed and acceleration. The pump also counts how often the syringe and valve move. These counts help you plan care before parts wear out.

Where Is an Industrial Syringe Pump Most Useful?

An industrial syringe pump is most useful when small amounts of liquid must move the same way many times. The SP60-nA series is made for pipetting, dilution, and dispensing.
