VEE GEE 4600P-SC100 is a replacement glass sample cell with bubble trap for the VEE GEE C25L Manual Polarimeter (4601P). The cell measures 100 mm in path length and holds 11 mL of sample, constructed from clear glass. The integrated bubble trap allows air bubbles to migrate out of the optical path, ensuring a clear, bubble-free light path through the sample and accurate polarimetric readings.
Features & Benefits
- Integrated Bubble Trap: The bubble trap reservoir allows air bubbles introduced during filling to migrate away from the optical path — eliminating the most common source of measurement error when loading viscous or freshly prepared samples into polarimeter cells.
- 100 mm Path Length: The standard 100 mm cell length is the internationally accepted path length for polarimetry in the pharmaceutical (USP/BP), food, and chemical industries — providing direct readings in degrees of optical rotation (°) per the standard convention.
- 11 mL Sample Volume: The 11 mL capacity accommodates typical lab sample sizes for sugar, pharmaceutical, and chemical optical rotation testing without requiring unusually large sample volumes.
- Clear Borosilicate Glass: Glass construction provides chemical compatibility with a wide range of aqueous and organic solvents used in polarimetry — including sucrose solutions, pharmaceutical actives, and essential oils — unlike plastic cells that can be degraded by organic solvents.
- Direct OEM Replacement: Factory-matched fit and optical alignment for the VEE GEE C25L Manual Polarimeter (SKU 4601P). One 100 mm cell is included with every new C25L polarimeter purchase — this SKU provides a direct replacement when the original cell is broken or needs to be retired.
- 1-Year Warranty: Backed by VEE GEE Scientific's standard accessory warranty.

Laboratory Applications
The 4600P-SC100 is the standard replacement cell for labs operating a VEE GEE C25L polarimeter. The 100 mm cell is the default measurement cell for polarimetry across pharmaceutical QC (USP optical rotation testing), food and beverage sugar analysis (sucrose concentration in syrups, juices, and confectionery), essential oil authentication, and academic teaching labs. The bubble trap is particularly valuable when measuring honey, viscous syrups, or other samples with a tendency to entrain air during filling — eliminating the need to wait for bubbles to clear before reading. For labs that require longer path length sensitivity with more dilute samples or higher precision, a 200 mm cell provides doubled sensitivity. For the complete C25L polarimeter instrument, see the VEE GEE 4601P Manual Polarimeter.
Frequently Asked Questions
Does the 4600P-SC100 come with the C25L polarimeter, or is it sold separately?
A 100 mm sample cell is included with each new VEE GEE C25L polarimeter (4601P) purchase. The 4600P-SC100 is the replacement part — sold separately for when the original cell is broken or needs to be replaced. If you are purchasing a new polarimeter, the 4601P already includes this cell.
What is the purpose of the bubble trap on this sample cell?
When filling a polarimeter sample cell, air bubbles can become trapped in the optical path, causing light scattering that produces inaccurate or unreadable rotation values. The bubble trap is a small side reservoir adjacent to the main tube — when the cell is filled and slightly tilted, bubbles migrate into the trap and out of the light path, giving a clear, bubble-free column for measurement. This is especially helpful with viscous samples like honey, sugar solutions, and pharmaceutical suspensions.
Can I use the 4600P-SC100 with other polarimeters, or only the VEE GEE C25L?
The 4600P-SC100 is designed and specified as a replacement for the VEE GEE C25L (4601P). Standard 100 mm glass polarimeter cells with bubble traps share a common general format across many polarimeter brands, but physical fit and seal integrity vary by instrument model. Compatibility with other brands cannot be guaranteed — verify dimensions and end-cap sealing requirements against your specific instrument before purchasing for non-VEE GEE applications.
What solvents are compatible with the glass 4600P-SC100 cell?
Glass cells are compatible with most aqueous solutions, dilute acids, dilute bases, alcohols, and common organic solvents used in polarimetry (ethanol, acetone, chloroform, DMSO, and similar). Glass is significantly more chemically resistant than plastic cells for solvent-based samples. Check that end-cap seals and any gasket materials are also compatible with your specific solvent system before use.
