Milwaukee MI0001 10 mL Glass Cuvettes for Photometers

The Milwaukee MI0001 is a genuine replacement set of two 10 mL optical glass cuvettes for Milwaukee's Mi4XX Photometer Series. If your photometer is giving inconsistent readings, throwing calibration errors, or the glass on your original cuvette is scratched, chipped, or stained from reagents, this is the exact replacement part your instrument needs. Each cuvette is manufactured to fit precisely into the Mi4XX's indexing chamber, so the light path stays consistent from test to test, which is what keeps your absorbance readings accurate and repeatable.

Why Choose This Product?

• Precision optical glass: Photometric accuracy depends entirely on how cleanly light passes through the sample. The MI0001's glass is manufactured to consistent wall thickness so the light path isn't distorted, which is what keeps your absorbance readings, and the parameter concentrations calculated from them, accurate.
• Designed for the exact indexing fit: Mi4XX photometers use a built-in indexing indent that locks the cuvette into the same position every time. The MI0001 is sized to seat correctly in that chamber, so your path length doesn't shift between the blank and the sample reading.
• Two cuvettes per box: One kit gives you a working pair, enough to keep a calibration/blank cuvette and a sample cuvette on hand, or to replace a damaged one immediately without waiting on a reorder.
• Genuine Milwaukee part: Matched to the manufacturer's specification for the Mi4XX line, rather than a generic aftermarket cuvette that may not seat the same way in the chamber.

Common Applications

Technical Specifications

Compatible Accessories / Consumables

• MI0002: Plastic cuvette caps, precision-fit to the MI0001 to prevent leakage during testing
• MI0003: Plastic stopper caps for the MI0001, used for sample storage and transport

Care & Handling Tips

• Handle cuvettes by the top edge or cap, since fingerprints on the optical surface can scatter light and skew readings
• Clean with distilled water and a lint-free cloth; avoid paper towel, which can scratch the glass
• Replace when you notice visible scratches, permanent reagent staining, chips, cracks, or inconsistent duplicate readings
• Keep a spare set on hand so a damaged cuvette doesn't stop testing mid-run

FAQs

What is the Milwaukee MI0001 used for?
It's a replacement glass cuvette (sample vial) for Milwaukee's Mi4XX Photometer Series, used to hold the sample during colorimetric water quality testing.

Which Milwaukee photometers use the MI0001 cuvette?
Any Mi4XX Series chemistry photometer, for example the MI404, MI405, MI406, MI407, MI408, MI411, MI412, MI413, MI414, and MI490.

Does the MI0001 fit the Milwaukee MI415 Turbidity Meter?
No. The MI415 turbidity meter uses a different cuvette (MI0011), not the MI0001.

How many cuvettes come in one MI0001 kit?
Two glass cuvettes per box.

What caps fit the MI0001 cuvette?
The MI0002 plastic cuvette caps and MI0003 plastic stopper caps are both designed to fit the MI0001.

Do I need to buy caps separately?
Yes, the MI0001 is the glass cuvette only. Caps (MI0002 or MI0003) are sold separately.

When should I replace my cuvette?
Replace it if you see scratches, permanent staining, chips or cracks, or if you're getting inconsistent readings between duplicate samples. Any of these can distort the light path and skew results.

Is the MI0001 suitable for wastewater or food & beverage QA/QC testing?
Yes, it's used across drinking water, wastewater, environmental, and food & beverage testing wherever a compatible Mi4XX photometer is in use.

Is the Milwaukee MI0001 available in Canada?
Yes, through Cambridge Environmental Products, priced in CAD and shipped from Ontario.
