Spritzenpumpen

Spritzenpumpen

Präzise, polyvalente und programmierbare Spritzenpumpen für das Labor

Heutzutage gibt es so viele verschiedene Spritzentypen und Volumen für Laboranwendungen:
Einige Anwender benutzen ausschliesslich Spritzen eines bestimmten Herstellers; andere verwenden für ihre Anwendungen nur Spritzen aus einem bestimmten Material, wie z.B. Glas, Metall oder Kunststoff. Zudem werden Spritzenvolumen ab wenigen Mikrolitern bis über 150 ml benötigt.

 

Ist es möglich mit nur einer der vielen angebotenen Spritzenpumpen alle Anwendungen im Labor zufrieden zu stellen?

 

 

Eine Spritzenpumpe für alle Anwendungen im Labor: LAMBDA VIT-FIT (HP)

Ja, es ist möglich mit nur einer Spritzenpumpe die unterschiedlichsten Anwendungen zufrieden zu stellen:

Spritzenfixiersystem von LAMBDA VIT-FIT bzw. LAMBDA VIT-FIT HP (für Hochdruckanwendungen) erlaubt beinahe jede Spritze einzusetzen, von Mikrospritzen bis hin zu Grossvolumenspritzen, ohne einen Adapter zu benötigen. Die Spritze ist fest in der Pumpe eingebettet und arbeitet in beiden Richtungen: Füllen und Entleeren.

 

Die klaren Vorteile unserer Spritzenpumpen für Ihr Labor
 

Besonders für langfristige Einsätze im Labor liefern LAMBDA VIT-FIT und LAMBDA VIT-FIT HP klare Vorteile gegenüber billigen Spritzenpumpen. Die Alleinstellungsmerkmale der LAMBDA Spritzenpumpe liegen in der exzellenten Konstruktion:

Zehnfach längere Lebensdauer

Für die Schubbewegung des Spritzenkolbens ist in der VIT-FIT Spritzenpumpen und VIT-FIT HP Hochdruck-Spritzenpumpen ein Schweizer Qualitäts-Motor eingebaut.

Die neue Technologie gewährleistet ein sehr hohes Drehmoment und eine zehnfach längere Lebensdauer.

Schwankungslose pulsationsfreie Linearität der Dosierung

Um die Rotation in eine lineare Schubbewegung umzuwandeln, ist eine Kugelgewindespindel mit höchster mechanischer Belastbarkeit in LAMBDA VIT-FIT & VIT-FIT HP Spritzenpumpen eingebaut.

Die Kugelgewindespindel gewährleistet zudem einen weiteren Vorteil der LAMBDA VIT-FIT (HP) Spritzenpumpen: Die hohen Schubsteifigkeit.
Die hohe Schubsteifigkeit ist entscheidend für die schwankungslose pulsationsfreie Linearität der Dosierung und für eine effiziente Kraftübertragung.

Damit sind LAMBDA VIT-FIT und LAMBDA VIT-FIT HP wohl die mechanisch robusteste und belastbarste Spritzenpumpe auf dem Markt.

 

Neue Hochdruckspritzenpumpen: LAMBDA VIT-FIT HP

Die robuste Konstruktion erlaubt auch die Meisterung von Hochdruckanwendungen:
Während die LAMBDA VIT-FIT Spritzenpumpen 300 N (umschaltbar auf 80 N) erbringen, meistern LAMBDA VIT-FIT HP Hochdruckspritzenpumpen Kräfte bis zu 600 N (umschaltbar auf 160 N)!

 

Sicherheit der Spritzenpumpen für Sie und Ihr Labor

Unsere Spritzenpumpen sind zu Ihrer Sicherheit ausgelegt:

Die Präzisionsmechanik der LAMBDA VIT-FIT (HP) Spritzenpumpen liegt geschützt im Pumpengehäuse. Das Gehäuse und der Hauptkörper sind aus Metall und lösungsmittelresistenter Beschichtung.

Der Kolbenvorschub mit dem Spritzenkolben ragt beim Füllen der Spritze NICHT aus dem Gehäuse heraus. Der Motor der Spritzenpumpe wird zudem automatisch ausgeschaltet, wenn die Spritze vollkommen geleert oder ganz aufgefüllt ist.

Hohe Sicherheit durch Niederspannung ist ebenfalls gewährleistet: Aufgrund der geringen mechanischen Verluste ist ein einfaches Stecker-Netzgerät mit Universaleingang (95 bis 240 V AC, 50/60 Hz) verwendbar.

 

Die Spritzenpumpen sind auch für Feldversuche einsetzbar:

Für Feldversuche kann die Spritzenpumpe auch mit einer 12 V Batterie oder einem Akku betrieben werden.

 

Einfache Bedienung der Spritzenpumpe

Jede LAMBDA VIT-FIT / LAMBDA VIT-FIT HP Spritzenpumpe ist einfach über das eingebaute Display bedienbar.

Die Bewegung des neuen bürstenlosen langlebigen BLDC Motors mit Neodym-Magneten ist andauernd unter der Kontrolle des Mikroprozessors. Die Elektronik korrigiert unverzüglich jede Abweichung von der Soll-Geschwindigkeit.

 

Schnelle Einstellungen direkt am Display der Spritzenpumpe

Für die schnelle Einstellung können Sie den Soll-Wert der Geschwindigkeit und die Richtung manuell am Display der LAMBDA Spritzenpumpen vorlegen bzw. auch während des Pumpens ändern.

 

Einfache Programmierung am Display

Bis zu 99 Programmschritte sind einfach am Display programmierbar und werden vom Prozessor er Spritzenpumpe gespeichert.

Die Spritzenpumpe ist in beide Richtungen programmierbar: Für das Füllen und Entleeren der Spritze (bzw. Entnahme und Infusion).

Das Programm kann in 1 bis 99 Zyklen oder in der Endlosschleife wiederholt werden.

 

Erleichterte Fernsteuerung der Spritzenpumpen im Labor

Analoge und digitale Möglichkeiten zur Fernsteuerung stehen Ihnen mit den LAMBDA VIT-FIT und LAMBDA VIT-FIT HP Spritzenpumpen im Labor zur Verfügung:

  • ON/OFF
    durch 3 bis 12 V DC oder einer höheren Spannung mit Vorwiderstand.

  • Progressive Geschwindigkeitskontrolle
    des gesamten Signalbereichs von 0 V DC bis 10 V DC
    (0 mA bis 20 mA   oder   4 mA bis 20 mA optional)

Der genaue Anschluss und die Buchsen finden Sie in der Bedienungsanleitung.

  • RS-485 oder RS-232 Schnittstelle (optional)
    für die Kommunikation mit einem PC oder einer ähnlichen Einrichtung.

Das RS-Kommunikationsprotokoll stellen wir Ihnen natürlich kostenlos zur Verfügung.

 

Anschluss an den PC, Datenspeicherung und Visualisierung

Um eine einfache Fernsteuerung ab PC / Laptop zu gewährleisten, empfehlen wir die optionale PNet Pumpensoftware. Sie können auch später weitere Spritzenpumpen (bis zu sechs Stück) an die erworbene PC-Software PNet anschliessen, dabei sind keine weiteren Lizenzen zu erwerben.

PNet erlaubt nebst der Fernsteuerung und Datenspeicherung auch die Visualisierung als real-time Diagramme, eine Option die besonders bei der Erstellung von Gradienten beliebt ist.

 

Anwendungsbeispiele der LAMBDA VIT-FIT Spritzenpumpen im Labor


Wie oben erwähnt, werden LAMBDA VIT-FIT (HP) Spritzenpumpen im Labor eingesetzt. Im Folgenden finden Sie typische Anwendungsbeispiele / Standardanwednungen:

  1. Konstanter Durchfluss:
    In dieser Standardanwendung der Spritzenpumpe bleibt der Durchfluss während der ausgewählten Dauer konstant.

    Anwendungsbeispiel: Lineare Edukt-Zugabe für die chemische Reaktion.

  2. Profil:
    Profil erlaubt die zuvor programmierte Änderung des Durchsatzes

    Beispiel 2.1 : Exponentiell zunehmender Durchsatz für den C-Feed einer Fedbatch-Fermentation in der Wachstumsphase.
    Beispiel 2.2: Linear erhöhter Durchsatz in der Chemie.

  3. Inkrement:
    Inkrement ist die stufenweise Erhöhung des Durchflusses als Funktion der Zeit.

    Anwendungsbeispiel: Herstellung von Flüssigkeitsgradienten in Auftrennungsverfahren.

  4. Dekrement:
    Dekrement ist die stufenweise Erniedrigung des Durchflusses.

  5. Pause:
    In der Pause stoppt die Spritzenpumpe für eine bestimmte Zeit, bevor sie zum nächsten Schritt übergeht

  6. Timer / Automatischer Start:
    Legen Sie den Zeitpunkt des Start der Dosierung ganz einfach über die Programmierung am Display oder die Fernsteuerung fest.

  7. Automatischer Stopp:
    Nachdem das Programm beendet ist, stoppt die Spritzenpumpe automatisch.

 

Als Hersteller und Händler von Laborspritzenpumpen stehen wir Ihnen für weitere Anwendungsmöglichkeiten gerne zur Verfügung.

  • Ansteuerung on / off: mit Kabel #4802
  • Ansteuerung on / off Umkehrsignal: mit Kabel #4824.

Bei der Fernsteuerung mit Kabel #4810-o (0 - 10 V) wird EIN Signal vom Fermenter kommen: Wenn 0 V der Spritzenpumpe anliegen, steht die Pumpe oder fördert die Pumpe mit einer minimalen Rate?

Wenn 0 V der LAMBDA VIT-FIT Spritzenpumpe anliegen, schaltet die Pumpe auf die Geschwindigkeit 000 (null). 000 = kein Fluss. Die Pumpe ist dabei nicht ganz abgestellt, nur fördert die Pumpe nicht mehr.


Wie speichere ich unterschiedliche Pumpprofile (Programme) für 2 ml, 5 ml, 10 ml Spritzen?

Zur Speicherung von unterschiedlichen Pumpprofilen bietet LAMBDA die PC-Software PNet an. PNet ermöglicht unterschiedliche Grundeinstellungen für die unterschiedlichsten Spritzen. 


Wann brauche ich den INTEGRATOR meiner Pumpe?

LAMBDA INTEGRATOR brauchen Sie, um die geförderten Mengen im Echtzeit-Diagramm darzustellen.
