Anwendungen der Schlauchpumpen im Labor

LAMBDA Schlauchpumpen kommen im Labor in der Fermentation, Biotransformation, technischen Mikrobiologie und in der Aufarbeitung zum Einsatz

  • Säure- und Basepumpen in der Fermentation (Bioreaktor, pH-Stat)
  • Fütterungspumpe / Aberntepumpe für kontinuierliche Zellkulturen
  • Auftragen der flüssigen Phase in der Säulenchromatographie

  • Dosierpumpen für Agar und Medium in der Versuchsvorbereitung
  • Pumpe für Autosampler

 

Die Probleme herkömmlicher Schlauchpumpen sind gelöst!

Die häufigsten Probleme herkömmlicher Schlauchpumpen sind:

  • Einzug des Schlauchs in Förderrichtung

Rollen mit kleinem Durchmesser setzen den Schlauch einer hohen Belastung aus und drücken ihn in Rotationsrichtung. Darum benötigen herkömmliche Schlauchpumpen oft spezielle Schläuche mit Stopper.

  • Abnutzung der Schlauchwand bis zur Leckage
  • Abnahme des Durchflusses beim Einsatz über mehrere Wochen
  • Massiver Geld- und Zeitverlust durch eine Pumpenstörung bei Langzeitversuchen

LAMBDA Schlauchpumpen hat genau diese Probleme gelöst:

 

Was macht die neue Schlauchpumpe von LAMBDA so effizient?

Die ausgeklügelte Mechanik macht LAMBDA Schlauchpumpen derart effizient: 

Rollen für eine niedrige Schlauchbeanspruchung und minimierte Pulasation

LAMBDA Schlauchpumpen fördern mit Rollen von grossem Durchmesser – damit wird die hohe Beanspruchung des Schlauchs eliminiert: Der Schlauch bewegt sich nicht in Förderrichtung und seine Elastizität bleibt erhalten.

Anstelle herkömmlicher Rollen setzt LAMBDA spezialgefertigte Plastikkugellager mit Glaskügelchen in den Pumpenkopf ein. Das Gleiten der korrosionsbeständigen Rollen benötigt nur eine minimale Kraft.

Ein exzentrischer Hebel und eine Feder aus korrosionsbeständigem Material komprimieren den Schlauch kontinuierlich und sanft.

Der resultierende Flüssigkeitsdruck liegt zwischen 0.1 und 0.2 MPa (je nach Schlauchbeschaffenheit). Der Druck steigt auch bei blockierter Linie nicht an.

Der grosse Pumpenkopf aus hartem, chemisch beständigem Material besitzt zwei asymmetrische Zentren, welche die Pulsation um ein Vielfaches verringern.

 

Motor für eine hohe Präzision

Der Schrittmotor oder BLDC Motor, betrieben durch eine quarzgesteuerte Elektronik, gewährt eine hohe Präzision der Fliessgeschwindigkeit.

 

Wichtige Vorteile für Ihr Labor

LAMBDA Schlauchpumpen bieten Ihnen die wichtigsten Vorteile für Ihr Labor:

Auch ohne Fixierung durch Stopper und Schlauchklemmen bewegt sich der Schlauch innerhalb des Pumpenkopfs nicht weiter.

  • Die Genauigkeit des Durchflusses bleibt Ihnen auch während Langzeitversuchen mit einer LAMBDA Schlauchpumpe gewährt.

Die Schlauchkompression wird im Bereich der Schlauchelastizität gehalten.

  • Eine höhere Lebensdauer der eingesetzten Schläuche

Sie können nicht nur kostengünstige Silikonschläuche einsetzen, sondern sparen auch an Ersatzmaterial.

What is the flow range?
Depending on the pump you select, our pumps offer a range of flow rates from 0.2 µl/min to 60,000 ml/hour.


Is the flow reversible?

Yes. The desired flow could achieved either by clock-wise or anticlock-wise rotation.


Could you please provide me information about the precision of dosing of a Lambda peristaltic pump? 
Accuracy of the pumps is about ±1% and the reproducibility is ±0.2% (electronics). Speed of rotation of the pump motor is regulated with a precision of quartz watch, which in-turn assures a high precision of the flow rate.


How would I calibrate the flow rate in peristaltic pumps?
The calibration of the pump flow rate with speed can be done to know the amount of the liquid pumped. It could be done in two ways: volumetric calibration of the peristaltic pump flow and pump flow calibration by weight. A short video of peristaltic pump flow calibration can be found at https://www.lambda-instruments.com/peristaltic-pumps/#video 


Can I get multi-channel pumps?
We do not manufacture multi-channel pumps. Because with the multi-channel pumps it is not possible to achieve the precise and reproducible flow rates with only one pump motor. For the high precision of flow rate, it is not advisable to use the multi-channel pumps.
If one channel gets blocked then your whole project will get spoiled totally. Instead, we recommend having individual pumps.


Why do I need to use LAMBDA individual pumps over multi-channel pump?
It has more advantages over the multi-channel pumps. The most important thing to take into account is the precise, reproducible and steady flow rate.
If one channel gets blocked then your whole project will get spoiled totally.
The bench space required for the needed channel equivalent to individual LAMBDA Pumps is same as that of a single multi-channel pump, because of the compact structure of the LAMBDA Pumps. 
The individual pumps can be used in other projects too.


Do you have pumps on stock?
Yes, we have the pumps in stock. We maintain a large stock of instruments, in order to be able to quickly set them up in the desired configuration and to dispatch them in shortest possible time, within few days!
