The Waters® Total Recovery Vial is a proprietary, exclusive product of Waters Corporation and has unique design features intended for autosamplers that use side‑port injection needles. While we cannot offer that exact vial, we do provide a high‑performance alternative designed for the same autosampler platforms in most situations.
Our Alternative: MICROSOLV™ MRQ™ Vials
MICROSOLV's MRQ™ vials were engineered to function in the same autosamplers that accept the Waters Total Recovery Vial, but with important design differences to match different needle geometries.

Key Differences to Understand
-
Needle Compatibility
- Waters Total Recovery Vials are intended for autosamplers that use a side‑port injection needle.
- MRQ™ vials are optimized for autosamplers with bottom‑port or bottom‑inlet needles.
-
Volume & Headspace
- MRQ™ vials hold slightly more total volume and provide additional headspace, which can be beneficial for certain sample prep conditions.
-
Recovery Well Design
-
Both vial types feature a recovery well, but the geometries differ:
- MRQ™: smaller bottom well, designed for stability.
- Waters TRV: longer, deeper well that extends lower in the vial.
-
Both vial types feature a recovery well, but the geometries differ:
-
Dimensions
- Both vials share the same 12 × 32 mm external dimensions and 9‑425 screw threads, so they fit identically into standard autosampler trays.
-
Base Stability
- MRQ™ vials include a wider base platform, improving stability in racks and trays without affecting instrument compatibility.
Summary for Customers
If your autosampler uses a side‑port needle, you must use the Waters Total Recovery Vial, as it is uniquely designed for that mechanism.
If your autosampler uses a bottom‑inlet needle, the MICROSOLV™ MRQ™ vial is an excellent, high‑performance choice that fits seamlessly into the same platforms while offering greater volume and stability.
