Peristaltic Pumps - Lambda - Description

Description of the PRECIFLOW — peristaltic pump
reliable, modern peristaltic pump, low price, flowrates 0.01 to 600 ml/hr *


Peristaltic Pump LAMBDA PRECIFLOW

The saving of costs between a tubing with stopper and the standard meter ware is so big that our peristaltic pump is paid after consumption of only 80 m of tubing.


  • • Rate settings from 0.01 to 600 ml/hr

  • • 5 years of warranty







Description of the MULTIFLOW — peristaltic pump
programming up to 99 steps of flow rates and time, flow rates 0.01 to 600 ml/hr *


Peristaltic Pump LAMBDA MULTIFLOW

The successful design and well-proved mechanics of our PRECIFLOW peristaltic pump has been extended by a flow rate programming. Up to 99 steps of time and flow rate can be easy programmed allowing any flow rate profile.



  • • Rate settings from 0.01 to 600 ml/hr

  • • 5 years of warranty

  • • The most compact programmable peristaltic pump on the market which weighs only 1 kg.




Description of the HIFLOW — peristaltic pump
programming up to 99 steps of flow rates and time, with flow rates up to 3000 ml/hr *


Peristaltic Pump LAMBDA HIFLOW

The development of this peristaltic pump was based on over forty years of laboratory experience and the systematic elimination of imperfections found in other pumps on the market. The result is a practical, precise and reliable pump which is the most compact in its class.



  • • Flow rates from 0.05 to 3000 ml/hr

  • • 2 years of warranty



Description of the MAXIFLOW — peristaltic pump
programming up to 99 steps of flow rates and time, with flow-rates up to 10 000 ml/hr *


Peristaltic Pump LAMBDA MAXIFLOW

The maximum flow rate has been increased to up to 10 000 ml/hr (10 lph). To achieve such a high flow rate in such a small instrument new motor technology has been used.





  • • Rate settings from 0.16 to 10 000 ml/hr *

  • • 2 years of warranty

  • •The most compact programmable peristaltic pump on the market which weighs only 1.2 kg.

Description of the MEGAFLOW — peristaltic pump
programming up to 99 steps of flow rates and time, with flow-rates up to 60 000 ml/hr *


Peristaltic Pump LAMBDA MEGAFLOW

MEGAFLOW is a specially designed laboratory peristaltic pump for long term continuous processes with increased flow rates of up to 60’ 000 ml/hour. High precision, reproducible and long term stable flow rates are achieved with the quartz driven BLDC motor and unique tubing compression technique in the large pump head

  • • Rate settings from 1.2 to 60 000 ml/hr *

  • • 2 years of warranty

  • • The stackable and extremely compact peristaltic pump saves valuable bench - space in your laboratory

* Tubing made of silicone or other material with similar elasticity (internal diameter 0.5 to 4 mm, wall thickness ~1 mm)

Common features:

  • • Digital set point extending over three orders of magnitude

  • Greatly extended tubing life and decreased pulsation

  • • Low voltage plug-in power supply for maximal safety

  • • The Pump Flow INTEGRATOR allows the exact recording of the amount of liquid delivered by the pump

  • Very economic in use while using low cost tubings without stoppers

  • The most compact programmable peristaltic pump on the market

  • Remote controls (analog and digital via RS-232 or RS-485 interface)

  • By programming zero flow rates the pump can be switched on and off without using a timer (for MULTIFLOW, HIFLOW and PRECIFLOW)

  • CE and IEC 1010/1 for laboratory instruments

  • Available plugs: US, UK, EU, CH

  • 90–240 V/AC, 50–60 Hz, 12 V/DC

Peristaltic pumps

The mechanics used in our peristaltic pumps is so gentle to the tubing that no clamps, fixings or stoppers are required. Therefore:

  • • A much better flow rate stability in time is obtained

  • • Low cost tubing can be used

  • • The saving of costs between a tubing with stopper and the standard meter ware is so big that our peristaltic pump is paid after consumption of only 80 m of tubing

    You should never buy peristaltic pumps using tubings with stoppers.


We know how expensive laboratory space is. Our peristaltic pumps are several times more compact than other peristaltic pumps. The same is true for all LAMBDA instruments.


Interesting construction features:

  • • Instead of small rollers, which are used by most pump producers, we use bearings of a larger diameter with glass beads. This reduces pulsations, friction and mechanical strain on the tubing leading to better pump performance.

  • • The bearings glide over the tubing so gently, that unlike other pumps, it is unnecessary to prevent movement of the tubing by a special fixation. In this manner the life time of the tubing is considerably increased.

  • • The pressure on the tubing is delivered individually through an off-center lever and spring made of stainless steel. This assures that a minimal pressure is applied to the tubing which still guarantees good functioning of the pump without unnecessary deformation of the tubing.

  • • The spring also reduces the liquid pressure to approx. 1 bar. This is useful when for any reason the line is blocked.

  • • The asymmetric pump head reduces pulsation.

  • • A high quality stepping motor together with integrated microprocessor electronics assure a high precision of flow rate with no inertia while turning the pump on and off.

  • • The pump head is made from hard, chemically stable epoxide.

  • • The pump dimensions have been minimized. Therefore the HIFLOW pump is considerably smaller than other products of similar performance. The pump is easy to use and saves space in the laboratory.

  • • Remote control and the possibility of flow integration increases the scope of use of the pump in automatically controlled systems (eg. fermentation, chemical synthesis, fraction collection, etc.)


Economical:

high quality/price ratio, low use-costs, easy handling

Remote control:

Remote control of the speed by external voltage 0—10 V (0—20 or 4—20 mA); ON/OFF control by external contact or 3—12 V voltage; compatible with other LAMBDA instruments (Pump-Flow Integrator and Omnicoll fraction collector); RS 485 as option

Pump-Flow Integrator:

Simple but precise integration of the amount of liquid which has been transported by the HiFlow peristaltic pump can be obtained by means of integrator.

The electric impulses which move the stepping motor are registered and transformed into a direct current. The voltage can be measured or recorded by common recorders or voltmeters.

In processes where the pump is controlled eg. by a pH-stat during a fermentation to keep the pH of the medium constant, it is frequently important to know when and how much acid or base were added. This data yields important information about the process, its kinetics and time of completion. The Integrator can also be used for measuring enzyme activity (eg. esterases, amidases, lactamases and other enzymes). The The Pump-Flow Integrator can be placed under the HiFlow pump.
