Usage Guide of Fused Quartz Flow Cuvette
Handling & Installation
-
Handle with Care:
Quartz is relatively fragile. Always handle flow cells gently and avoid applying pressure to optical windows. -
Proper Tubing Connection:
Ensure tubing fits properly without excessive force. Over-tightening connections can crack the flow cell. -
Flow Rate Control:
Begin with low flow rates and gradually increase to operating conditions to prevent pressure spikes. -
Avoid Air Bubbles:
Ensure flow systems are properly primed to eliminate air bubbles that can disrupt measurements.
Cleaning Procedure
-
Regular Flushing:
After each use, flush with distilled water (3 times) to remove sample residue. -
Organic Contamination:
For organic residue, use a 50:50 mixture of ethanol and diethyl ether, followed by distilled water rinse. -
Stubborn Deposits:
For difficult contaminants, use specialized quartz cleaning solution for no more than 10 minutes, then rinse thoroughly. -
Avoid:
Never use alkaline solutions, detergents, abrasive cleaners, or brushes. Avoid prolonged exposure to hydrofluoric acid or high concentration fluoride solutions.
Storage & Maintenance
-
Dry Storage:
After cleaning, allow flow cells to dry completely by flushing with air or drying in a dust-free environment. Store in original protective case. -
Regular Inspection:
Periodically inspect flow cells for scratches, cracks, or deposits. Check optical clarity by running baseline measurements. -
Solvent Compatibility:
While quartz is resistant to most chemicals, verify compatibility with new solvents before extended use, especially with concentrated alkalis. -
Temperature Control:
Avoid rapid temperature changes that can stress the quartz material. Allow flow cells to gradually reach operating temperature.

FAQ
Q: What is the wavelength range for TOQUARTZ® quartz cuvette flow cells?
A: TOQUARTZ® high-purity quartz flow cells provide excellent transmission across a wide spectral range from 200nm in the deep UV to 2500nm in the infrared region. Unlike glass cuvettes that absorb below 320nm, quartz flow cells are essential for UV spectroscopy applications and offer no absorption peaks throughout their transmission range.
Q: What is the proper quartz cuvette cleaning procedure for quartz flow cell?
A: For routine cleaning, flush the flow cell with distilled water three times after use. For organic contaminants, use a 50:50 mixture of ethanol and diethyl ether followed by distilled water rinse. For stubborn deposits, specialized quartz cleaning solutions can be used briefly (less than 10 minutes) followed by thorough rinsing. Never use alkaline solutions, detergents, abrasive cleaners, or brushes that can damage the quartz surface.
Q: What is the solvent compatibility of quartz cuvette flow cells?
A: Quartz flow cells are compatible with most laboratory solvents including water, alcohols, acetone, acetonitrile, DMSO, THF, hexane, toluene, chloroform, and dilute acids. They resist most organic and inorganic compounds. However, hydrofluoric acid (HF) and concentrated fluoride solutions should be avoided as they can etch quartz. Concentrated alkaline solutions should also be used with caution for prolonged periods.
Q: What is the typical absorbance range for quartz flow cells?
A: The absorbance range depends on the flow cell path length and your instrument’s capabilities. With TOQUARTZ® flow cells, you can measure absorbances from as low as 0.001 AU to over 3.0 AU depending on your detector sensitivity. For high absorbance samples, shorter path lengths (0.1-1mm) are recommended, while low concentration samples benefit from longer path lengths (10-100mm) to enhance sensitivity.
Q: What is the difference between Z-path and linear flow cells?
A: Z-path flow cells feature inlet and outlet ports on opposite sides with a Z-shaped flow channel, offering better flow dynamics and reduced bubble trapping. Linear flow cells have a straight flow path with ports typically on the same side. Z-path designs are preferred for automated systems and continuous flow applications, while linear designs are often simpler and more economical for basic applications.
