TOPT-V Photoreactor Delivered For Lab UV–Vis Research

On Jan 13, 2026, we shipped a TOPTION TOPT-V photoreactor(8-position, 300 W xenon + 300 W mercury) to a university laboratory in Kazakhstan, which has UV-Vis light simulation and an eight-position screener in parallel. This article summarizes the delivered setup, QC checklist highlights, and the most important safety tips for the routine operation of labs.

Shipping Date: January 13, 2026

Destination: Kazakhstan

Item: Photoreactor, TOPT-V model

Highlights

• Light sources: 1 unit of 300 W xenon lamp with 1 unit of controller, 1 unit of 300 W Mercury lamp with 1 unit of controller.
• Capacity: 8-position parallel magnetic stirrer.
• Thermal Control: All-quartz cold trap (lamp heat removal) + 8 all-quartz reaction tubes.

"In the box" documents

Quality certificate (QC report), specification sheet, warranty card, certificate of conformity (CoC), and packing list.

Light source options (choose per experiment)

• 300 W xenon lamp + controller for simulating visible light. The xenon output profile matches visible light, and with the provided controller, it will run stably.
• 300 W mercury lamp + controller for strong UV presence. Mercury lamps provide a strong UV component. The exact UV/visible distribution depends on the lamp type and filters; refer to the spectral data included with the shipment. It requires about 5 mins of warm-up. If it has been powered off, wait ≥5 mins before turning it on again. Wear UV-rated protective goggles/face shield (e.g., UV400) when operating mercury lamps. Regular prescription glasses or non-rated sunglasses are not sufficient UV protection.

Parallel reaction productivity

• An 8-position magnetic stirrer + 8-quartz tubes allows for multi-sample screening and collection in a single operation.

Quartz protection & cooling stability

• The quartz cold trap helps stabilize reaction temperature during long runs by removing lamp heat while maintaining high UV/visible transmission.

Reaction vessels & sealing

• Set shipped: 8 pieces of 150 mL all-quartz test tubes with PTFE sealing plugs for reactions.
• Manual options: 100 mL quartz tubes in standard and air-inflation configurations, both with PTFE sealing plugs.

The TOPT-V accommodates photocatalyst evaluations, including TiO₂ photocatalyst, for gas, liquid, and solid-state photochemistry under simulated visible or UV light. Typical fields include chemical synthesis, environmental science, and life sciences.

1. "Peer-reviewed studies have reported using the TOPT-V / Toption-V 8-position batch photoreactor (300 W xenon, quartz cold trap) for simulated solar irradiation and photocatalytic experiments."
2. "Examples: Processes (2024) 10.3390/pr12061265; Foods (2024) 10.3390/foods13162643."

• Environment: Maintain ≤30 °C and ≤ 60 % RH. Operating outside these limits may reduce performance and increase safety risks.
• Power & grounding: AC 220 V / 50 Hz with adequate protective grounding. Use a grounded outlet and plug type compliant with local electrical standards.
• UV protection: Mercury lamps emit UV; Wear UV-rated protective goggles (UV400) or a face shield when operating mercury lamps. Regular sunglasses are not adequate unless they are UV-rated and fully sealed.
• Ventilation & placement: clear all of the heat-dissipating zones, and ensure no dust, heaters, or direct sunlight.
• Do Not Move the Unit When Filled: Once coolant/medium is added, do not move or tilt the system to avoid leaks and damage.
• Maintenance boundary: Do not open the instrument; Repairs other than fuses and condenser cleaning are to be done by certified personnel.

Before sealing the crate, our team confirms:

• Visual inspection + power-on checks regarding controllers, fans, and flow circulation, per the manual's operating/install steps.
• Lamp components on the packing list: xenon/mercury lamps, controllers, 8-position stirrer set, quartz cold trap and quartz tubes, protective dark box, trolley, and spare parts.
• Documents included: specification, warranty card, and quality/qualification certificate, all of which are in the carton, and the packing list (in the carton).

• Serial number recorded / QC pass label

• Lamp warm-up & restart interval verified
• Grounding continuity check performed

1. What are your absorption wavelengths? Do you need UV or UV-Vis (mercury vs xenon)?
2. How many samples will you measure? Just a single sample or an 8-position parallel?
3. Do you need to control the influence of temperature? Use the fully-quartz cold trap and connect to your cooling loop.
4. What type of vessels do you need? Sealed quartz tubes or air-inflation quartz tubes?
5. What's your power standard? Confirm 220 V/50 Hz and grounding.
6. Do you need flow circulation? Select a multi-port glass reactor with micro-circulation and a flowmeter.

Q1: Xenon vs mercury-how do I choose a photoreactor lamp?

A1: Use mercury lamps when you need a strong UV component. The UV/visible distribution depends on the lamp type and filters; refer to the spectral data provided with the shipment.

Q2: Why does the photoreactor use a quartz cold trap?

A2: The all-quartz cold trap removes heat from the lamp zone during long runs, helping stabilize reaction temperature while maintaining high UV/visible transmission.

Q3: What is the volume of each quartz tube?

A3: The manual states 100 mL for the standard and air-inflation tubes, and this shipment contains eight 150 mL quartz tubes that are sealed. Select volume based on your catalyst loading and analysis requirements.

Q4: What are the requirements for the room and power?

A4: The room temperature should be ≤ 30 °C, the relative humidity should be ≤ 60%, and the power supply should be AC 220 V / 50Hz and should have a grounded outlet.

Q5: What safety steps are in place to minimize exposure to UV light?

A5: Use the light-shielding dark box, never look directly at the lamp, and wear UV-rated protective goggles (UV400) or a face shield when operating mercury lamps. Non-rated sunglasses are not adequate.
