The APELEX PS 304 XL is a precision benchtop DC power supply designed for controlled voltage and current output in laboratory environments. It provides a voltage range of 1 to 300 V with a resolution of 1 V per step, and a current range from 1 to 400 mA with 1 mA step increments, delivering a maximum power output of 100 W. This electronic power source features minimum regulation thresholds of 1 V, 15 µA, and 0.3 W, ensuring fine control essential for sensitive molecular diagnostics, synthetic biology, and biotechnology experiments requiring stable electrical conditions.
Key technical specifications include:
This laboratory power supply is widely used in precision biopharmaceutical production pipelines, molecular cloning workflows, and biomedical engineering applications where reliable and adjustable DC voltage and current sources are critical. Its compact size and accurate control make it suitable for research settings focusing on gene editing and bioprocessing tasks, offering dependable performance for sensitive instrumentation and experimental setups.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
