Pumps and Dosing Systems for Laboratories and Pilot Plant
Precise. Reproducible. Automatable.
Accurately convey, dose and feed liquids and solids: HITEC ZANG offers the right dosing technology for laboratories, pilot plants and process engineering test rigs.
- Syringe pumps: Precise dosing of the smallest volumes, without pulsation
- Peristaltic pumps: Continuous delivery of liquids with no contact between pump and medium
- Solid dosing devices: Dosing of powders and granules with adjustable feed rate
- Autosampler: Automated, time- or event-controlled sampling

Frequently Asked Questions
When is a syringe pump the right choice, and when a peristaltic pump?
Our SyrDos syringe pumps are the right choice when flow rates are in the ml/min range, when low-pulsation delivery is required, when high media resistance is needed and when higher pressures are to be reached.
The LabDos peristaltic pumps offer very good value for money and excel with demanding media: the pump tubing is the only wetted part and is also suitable for aggressive, highly viscous or shear-sensitive media. When changing substances, simply switching to new tubing is enough. This saves time and rules out residues, which is particularly important for purity requirements in the biotech and medical fields.
Which materials and applications are solids dosers suitable for?
Solids dosers deliver powders, granules and other free-flowing solids reproducibly in exactly specified amounts, from a few milligrams up to the gram and kilogram range.
Typical fields of use are laboratory and process automation, formulation development, pharmaceutical and chemical applications, and materials research.
Die passende Dosiertechnik hängt von Eigenschaften wie Rieselfähigkeit oder Partikelgröße ab. Bei der Auswahl beraten wir Sie gerne auf Wunsch mit einem Test Ihrer Originalsubstanz.
Can the devices be combined and integrated into existing laboratory workflows?
Yes, all our devices can be integrated into automated workflows. The SyrDos syringe pumps, LabDos peristaltic pumps and LabDos Solid solids dosers take care of dosing liquids and solids. The AutoSam sampling systems automatically fill samples into defined containers or provide starting materials for reaction batches.
Via interfaces such as RS-232, RS-485 (Modbus) and analog and digital inputs and outputs, the systems can be linked into a seamless workflow with the LabVision Software, the LabManager or your own control system.
