Dissolution Testers

ERWEKA is a distinguished manufacturer offering an extensive range of both manual and automated dissolution‑testing systems, designed to accommodate every major pharmacopeia method. From traditional USP 1, 2, 5, 6 testers to advanced solutions like USP 3/7 (BioDis) and USP 4 flow‑through cells, ERWEKA supports the broad spectrum of dissolution testing requirements in pharmaceutical development, quality assurance and regulatory compliance.

USP 1, 2, 5, 6 – Automated Systems – Learn more

ERWEKA’s DT 950/9510‑based systems deliver 100 % USP‑conform dissolution testing in fully automated formats. Whether you need automated sampling and collection, UV‑Vis online analysis, or full integration with HPLC, ERWEKA offers:

• Digital Offline System (automated sampling + storage)
• Dissolution Online System (sampling + UV‑Vis analysis)
• HPLC On/Offline System (direct injection into HPLC)

All systems are controlled via ERWEKA’s Disso.NET software with method memory, audit‑trail functionality, Active Directory integration and full dataset management.

USP 1, 2, 5, 6 – Single Device Solutions – Learn more

For laboratories with smaller throughput or budget constraints, ERWEKA provides single‑device dissolution testers including the DT 950 and DT 9510 series (6‑14 test stations with TestAssist) and the DT Light series (6 or 8 stations) — all fully USP‑conform and upgradeable.

USP 3 / 7 – BioDis RRT 10 – Learn more

The BioDis RRT 10 is designed for extended and sustained‐release dosage forms. With programmable pH gradients, multiple media rows and automatic sample transport, it supports USP 3 and USP 7 testing standards (or a combination of both) and is 100 % USP/EP/JP‑compliant. Features include a touch display, automatic evaporation cover, external flow‑through heater and vessel options from 50 ml to 1000 ml.

USP 4 – Flow‑Through Cell DFZ II – Learn more

ERWEKA’s DFZ II flow‑through cell tester is ideal for products with low solubility, low dose forms or implants. Innovations like the “three‑part” standardized cell head, quick‑lock tubing, improved leak‑tightness and individual cell heating provide faster cell preparation and stable testing. The Disso.NET USP 4 software supports method editing, full reporting, XML output and GMP‑compliant data handling.

Media Preparation – MediPrep Series – Learn More

The MediPrep systems automate and accelerate the preparation of dissolution media:

• MediPrep 820 (up to 8 L in <15 min)
• MediPrep 1622 (up to 16 L in ~25 min)

Both ensure 100 % USP / EP / JP compliance, degassing, heating and gravimetric filling with high accuracy.

Chewing Gum Testers – DRT Series – Learn more

For chewing‑gum and similar dosage‑forms that require mastication, the DRT tester replicates jaw movement and agitation of medium, supporting multiple stations, sampling, cleaning, and advanced accessories for masticatory force, pH and temperature measurement.

Dissolution Tester Software – Disso.NET 4 – Learn more

Disso.NET 4 is ERWEKA’s comprehensive software platform for all dissolution systems. It supports multi‑user roles, audit‑trail logging (what/who/when/why), PDF/XML reporting, database backup & restore, method memory and FDA 21 CFR Part 11 compliance.
