ULVAC DA-40S Diaphragm Dry Vacuum Pump for Laboratory and Industrial Use
Product Description
The ULVAC DA-40S is a diaphragm-type dry vacuum pump designed for reliable vacuum generation in laboratory and bioprocessing applications. Utilizing the reciprocating motion of a rubber diaphragm, the pump provides oil-free vacuum exhaust, making it ideal for sensitive environments such as molecular diagnostics and biomanufacturing pipelines.
Key features include:
- Oil-free dry pump design ensuring contamination-free operation critical in synthetic biology and fluorescence analysis workflows.
- Ultimate pressure of 19.9×10³ Pa (-81.4 kPa) delivers efficient vacuum suitable for applications in clinical diagnostics and cell imaging.
- 60 W motor power balancing effective performance with energy efficiency.
- Simple structure enables easy maintenance and minimal downtime in biopharmaceutical production settings.
- Compatibility with ambient atmospheric operation from 7 to 40 °C, supporting diverse laboratory environments.
- Compact dimensions (128×242×178 mm) and lightweight design (7.2 kg) facilitate benchtop use in confined lab spaces.
- Optional unloader valve improves pump starting characteristics by introducing atmospheric air during stop cycles, enhancing operational reliability in continuous bioprocess applications.
- Built-in automatic reset thermal protector ensures safe and durable operation under varied conditions.
Widely used in biotechnology and biomedical engineering, the DA-40S is essential for molecular cloning workflows and general laboratory vacuum tasks where clean, oil-free vacuum is required. This used unit is sold as-is; prior performance may vary, but warranty coverage is offered for initial defects within 10 days post-delivery.
