What Is a Peristaltic Pump Used For? Labs, Factories, Devices?

What is a peristaltic pump used for? It works on a lab bench and on a filling line. It can also sit inside a machine. This article uses facts from Innofluid Co., Ltd. The company makes peristaltic pumps.

A peristaltic pump is used to move, dose, and fill liquids. Labs use it to move cell fluid, dispense chemicals, and run liquid chromatography. Factories use it to fill and dispense. Machine makers build it into test equipment.

Labs, factories, and device makers all use these pumps. The jobs differ. The pump stays the same.

What Is a Peristaltic Pump Used For in Real Work?

A peristaltic pump does five main jobs. It moves liquid, feeds it, takes samples, adds exact doses, and fills containers.

The five main jobs

Liquid transfer: moves cell fluid and chemicals from one place to another.

Media feeding: adds food for the cells to a bioreactor.

Sampling: takes a small bit of liquid to test.

Chemical dosing: adds a tiny, exact amount of a chemical.

Filling: puts liquid into bottles, vials, or plates.

In labs, the pump moves cell fluid, dispenses chemicals, and runs liquid chromatography. In factories, it fills and dispenses. This work covers medicine, cosmetics, food and drinks, and diagnostic tests.

Where Are Peristaltic Pumps Used? A Quick Map by Setting

Peristaltic pumps are used in labs, bioreactors, filling lines, reagent plants, and instruments.

The same pump type shows up in every row. Only the size, the control, and the tubing change.

Why Does the Liquid Stay Clean? Fluid Isolation in the Hose

Fluid isolation means the liquid only touches the hose. Innofluid says the liquid passes through the hose alone, so nothing pollutes it. That keeps the liquid clean.

What the website says about clean transfer

The bioreactor page lists three good points. They are non-pollution, low shear, and high precision.

The fermentation page says fluids must not affect each other. Its KT15 series has four peristaltic pumps. They move acid and alkali solution, nutrient solution, and defoaming solution. Each one has no cross influence on the others.

How Do Labs Use Liquid Transfer Every Day?

Labs use a peristaltic pump to move cell fluid and chemicals. The Laboratory application page names three tasks. They are moving cell fluid, dispensing chemicals, and liquid chromatography.

The same page lists four fields. They are chemical reagents, water treatment, culture medium, and filtering.

Moving cell fluid

Dispensing chemicals

Liquid chromatography

Water treatment

Filtering liquid

How much can a lab pump handle?

The LabV6 pump is one example. Its flow rate is 0.0053–2580 mL/min. Its speed range is 0.1–600 rpm. These numbers are for the LabV6 only.

How Do Bioreactors Use Media Feeding, pH Control, and Sampling?

Bioreactors use peristaltic pumps to feed liquids, hold pH, and take samples.

What fermentation equipment needs

The Biological Fermentation Field page lists four needs:

1. Moving media, and taking and collecting set amounts of samples

2. Control of the pH level

3. Feeding nutrient solution, defoaming solution, and other liquids

4. Pulling out and separating fermentation products

Small and large bioreactors

In small lab bioreactors, acid and alkali liquids keep the pH balanced. Defoamer is added to remove bubbles. The OEM-Minipump, OEM-UD15, and OEM-Micro series need only a tube change. Popular models are OEM-B01, OEM-UB01, and OEM-STAB06.

Bigger pilot-scale bioreactors need more flow. The site names a gear pump or a large flow rate peristaltic pump. For large volume (3L–24L) dosing, it lists a 304ss and 316ss shell peristaltic pump. Popular types are the N6 series and the LabGV series.

The KT15 pump head is small. You flip it to open the upper block. The flexible upper block helps the tubing last longer.

How Do Factories Use Filling and Chemical Dosing?

Factories use peristaltic pumps for aseptic filling and exact dosing. The Industry application page covers medicine, biotech, cosmetics, food and drinks, and diagnostic work.

Example 1: E-liquid filling

The LabF6-III/EasyPump is on the E Liquid Filling Pump page. It has a 4.3" LCD touch screen. You can set the fill amount, fill time, and pause time ahead of time.

It also has a back suction function and online calibration. Its flow accuracy is ±0.5%. It saves 60 common data sheets. It can handle all kinds of fluid, even thick or corrosive ones.

The page also lists oral liquid and diagnostic reagents for chemical dispensing. For cosmetics, it lists perfume and lip gloss.

Example 2: Plate filling

One Innofluid pump is made to fill a 96 deep well plate. Its filling efficiency is up to 5 seconds per board.

Example 3: Reagent dispensing

The nucleic acid detection reagent system dispenses 8 different reagents. Its dispensing accuracy is 0.5%. Batch dispensing is 30 times more efficient than hand dispensing.

It has a 7-inch industrial-grade LCD touch screen. Two-way quick filling makes it easy to clean the hose.

The site also lists IP66, IP67, and IP68 industrial pumps. It lists an explosion-proof pump range too.

Are Peristaltic Pumps Used Inside Instruments and Medical Devices?

Peristaltic pumps are built into instruments as OEM parts. The OEM Supporting page says OEM peristaltic pumps are widely used in water quality and bio-chemistry analytical instruments.

Innofluid supplies complete peristaltic pumps, pump heads, and OEM peristaltic pumps. It also offers ODM service and complete fluid solutions.

The home page lists OEM supporting solutions for medical devices and in vitro diagnostic instruments. The heading is "medical fluid precision control." That is only a headline. Ask the company for details before you plan a device.

How Do You Match a Pump to the Job?

Check five things: accuracy, flow, speed, fluid type, and tube change. Each spec is for one model only.
