Description
Valve control box for LA-xx pumps is a laboratory accessory that links valve actuation to pump direction for coordinated fluid handling. Depending on the pumping direction, up to two valves can be opened or closed, supporting automated path switching in research and analytical setups. The unit includes a 12 V DC power supply for the valves; the valves themselves are not included in the scope of delivery. Intended for use with LA-xx series pumps, this control box from manufacturer Landgraf HLL helps integrate directional valve control into existing laboratory pumping configurations. Supplied as one piece, it is suited to workflows that require synchronized open/close behaviour without manual valve intervention at each direction change. By tying valve state to pump direction, the accessory simplifies multi-valve arrangements and supports consistent fluid routing during dispensing or transfer steps. It is designed for laboratory environments where reliable accessory control complements programmable or continuous pump operation. Country of origin is the USA. Choose this valve control box when LA-xx pumps need compact, direction-dependent valve management with dedicated low-voltage supply for the actuators.

Questions about Valve control box for LA-xx pumps
What is this article?
Valve control box for LA-xx pumps is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
