Laboratory pumps

Laboratory pumps for precise transport and dosing

Precision liquid pumping is the domain of laboratory pumps, essential for scientific research and rigorous quality control. These devices provide exceptional accuracy, which is crucial in the production of medicines and cosmetics. Their main advantages are:

• measurement error of only 1%,
• repeatability of 0.2%,
• wide flow range - from microliters to 60 l/h,
• full compliance with GLP and GMP standards,
• No risk of contamination of samples.

Depending on the needs, specialists use peristaltic, vacuum, membrane or piston models. Systems such as CAT, FlexiPump or PL2, supported by standard SOP procedures, guarantee stable operation and the highest efficiency in any modern laboratory.

CAT DP200 Series Micro Dosing Pumps With Ceramic Heads

The CAT DP200 models guarantee the highest precision in dispensing even the most demanding liquids. Their design is based on durable ceramic heads (such as 20VCS and 200TCS), which ensures full resistance to corrosion and aggressive chemical reagents.

These devices are distinguished by the following features:

• high precision of liquid dispensing,
• resistance to corrosion and aggressive reagents,
• the ability to work with dense media,
• maintaining full sterility of the process,
• easy integration with laboratory reactors,
• work in pressure systems,
• exceptional repeatability of results.

Users can choose from three performance variants:

• from 1 μl to 50 ml (flow rate up to 4 ml/min),
• from 10 μl to 500 ml,
• from 20 μL to 1000 mL (flow rate up to 60 mL/min).

With the ability to feed substances directly into pressurized systems, this series is indispensable for complex syntheses and analyses where the margin of error must be kept to a minimum.

FlexiPump peristaltic pump for media and agar

FlexiPump from Interscience is an advanced system for precise dosing of media and agar, designed for the highest standards of work in the microbiological laboratory. The device significantly improves fermentation processes and bioreactor management, with particular emphasis on sterility and hygiene.

Thanks to its unique design, the fluid only comes into contact with flexible hoses, eliminating the risk of contamination of the pump mechanism. Its advantages include:

• high precision of dosing liquid media,
• complete elimination of the risk of contamination of the mechanism,
• self-priming function, making it easier to start work,
• safe dry operation, protecting against failures,
• Availability of models with one or two heads,
• Significantly accelerate routine research tasks.

Intuitive operation and the possibility of choosing the configuration of the heads make the FlexiPump an extremely flexible tool. It allows for rapid media pouring under controlled conditions, resulting in higher efficiency and repeatability in any modern laboratory.

3 and 6 roller heads and flow rates up to 2.5 l/min

FlexiPump systems guarantee high dosing precision thanks to two configurations available: a single head with three rollers or a double variant with six. The special design effectively minimizes liquid pulsation, which translates into a capacity of up to 2.5 liters per minute.

The device is based on durable cables - made of silicone or santoprene. These materials are characterized by exceptional abrasion resistance, which allows for trouble-free operation during many hours of laboratory sessions. The diameter of the hose directly affects the pumping speed, and the multi-channel option allows you to fill two vessels at the same time, which significantly improves testing processes.

The key to achieving reliable results is attention to technical details and regular maintenance of the device. The following factors facilitate the achievement of full optimization of work:

• precise calibration - taking into account the viscosity of the medium,
• the use of materials resistant to intense abrasion,
• the possibility of filling multiple vessels at the same time,
• maintaining full repeatability of each cycle,
• Systematic replacement of hoses for occupational hygiene.

Valveless design with minimal dead volume

The modern pump design, based on the abandonment of valves and seals, almost completely eliminates dead volume, which guarantees exceptional dosing precision. The use of PTFE elements ensures full chemical inertness, and the absence of mechanical valves effectively prevents the crystallization of reagents. This allows you to maintain the stability of the device even in a very demanding environment.

These solutions are perfect for many processes, such as:

• analytical chromatography,
• advanced flow systems,
• precise dosing of iron chloride,
• effective coagulation and flocculation,
• sedimentation processes,
• effective phosphate removal.

The biggest advantage of the device is the smooth, pulsation-free flow. High resistance to aggressive chemicals and reliable stability make this solution ideally suited to the needs of modern laboratories, ensuring the highest quality and repeatability of results.

Digital control, calibration and connection to a PC

Modern laboratory pumps - based on stepper and brushless motors - guarantee exceptional precision. With digital control and RS-232 and RS-485 connectors, these devices automate testing processes, reducing dispensing errors by 25%. This is crucial in environmental monitoring and precise pH regulation.

Other advantages include:

• advanced drives to ensure flow stability,
• intuitive touch panels for easy setup,
• direct communication with the computer and preview of parameters,
• external control pedal - frees the laboratory technician's hands,
• robust housing with a high IP tightness class,
• Regular calibration, saving costly reagents.

High resistance to harsh environments and remote monitoring of work increase the efficiency of tests. The robust design effectively protects sensitive systems from spillage, ensuring the reliability of the equipment.

PL2 Vacuum Pump for Laboratory Filtration

AGA LABOR's PL2 vacuum pumps are advanced devices that support dosing systems that significantly optimize sample preparation time. The membrane technology used completely eliminates the need for oil, which effectively protects the test substances from vapor contamination and ensures full reproducibility of results.

The devices are characterized by exemplary operational stability even during intensive, continuous gas pumping. Users can precisely select the equipment for the specifics of their research by choosing from four capacity variants: 9, 19, 20 or 36 l/min.

Their versatility makes them indispensable in chemical and pharmaceutical laboratories, where they support key processes:

• vacuum filtration,
• distillation under reduced pressure conditions,
• operation of rotary evaporators,
• drying and extraction processes,
• degassing samples,
• Safe phase separation.

A key advantage of the PL2 series is its exceptional durability. By choosing this solution, you focus on high efficiency and impeccable process cleanliness, which is essential in everyday research work.
