8 best lab vacuum traps

Lab vacuum traps are important components in laboratory settings, particularly when working with vacuum pumps or other vacuum systems. These traps are designed to capture and prevent the entry of unwanted materials, such as liquid contaminants or particles, into the vacuum pump or vacuum system. They play a crucial role in maintaining the integrity and efficiency of vacuum operations. Here is what you should know about lab vacuum traps:

  1. Purpose: The primary purpose of a lab vacuum trap is to protect vacuum pumps and vacuum systems from damage caused by liquid or solid contaminants. It does this by capturing these contaminants before they can enter the pump or the vacuum system.

  2. Design: Vacuum traps typically consist of a glass or stainless steel container connected to the vacuum line.They are equipped with a removable or replaceable collection container (trap body) and a condenser coil or cold finger. The trap body is filled with an appropriate trapping medium, such as a cold solvent or dry ice/acetone mixture, which helps condense and capture contaminants.

  3. Operation: When the vacuum system is in operation, the trap collects any volatile or condensable substances, preventing them from progressing further into the vacuum pump. The cold finger or condenser coil cools down the trapped substances, causing them to condense and form droplets that collect in the trap body.

  4. Types of Vacuum Traps: There are various types of vacuum traps, including dry traps and wet traps. Dry traps use desiccants or absorbent materials to trap moisture and other contaminants. Wet traps use cold traps to condense and trap vapors. The choice of trap type depends on the specific application and the nature of the contaminants.

  5. Applications: Vacuum traps are commonly used in a wide range of laboratory applications, such as rotary evaporation, freeze-drying, distillation, and vacuum filtration. They are essential when working with volatile or hazardous substances that may contaminate or damage the vacuum pump.

  6. Maintenance: Regular maintenance is important for vacuum traps to ensure their proper functioning. This includes emptying and cleaning the trap body, replenishing trapping medium (if applicable), and checking for any leaks or blockages.

  7. Safety: Vacuum traps contribute to laboratory safety by preventing the release of hazardous substances into the environment or the vacuum pump. They also protect the vacuum pump from damage, extending its lifespan.

  8. Compatibility: When selecting a vacuum trap, it is important to ensure compatibility with the specific vacuum pump or system being used. Proper connections and fittings are essential to prevent leaks.

  9. Sizing: The size and capacity of the vacuum trap should be chosen based on the expected volume of contaminants and the type of experiment being conducted.

Overall, lab vacuum traps are critical components in laboratories where vacuum operations are performed, helping to protect equipment, maintain experimental integrity, and ensure the safety of researchers and the environment.

User questions & answers

Question: can I replace the tube with a std test tube
Answer: Qualified Yes. As long as the glass can withstand the vacuum and the temperature of the cooling bath, and the the inlet and outlet tubes can be arranged with no air leak so the vacuum is maintained, the cold trap can be cylindrical like a test tube or conical (not comical!) like an erlenmeyer flask, etc.

User questions & answers

Question: How do you clean the fitting the resin passes through? why arnt there any instructions anywhere on their practical use
Answer: For any of the metal components on this item you can clean the resin off with alcohol. We recommend anything 99% so Isopropyl Alcohol works best. As for the gasket and any other non-metal item D-limonene works to clean the resin off these components. I hope this helps!
Question: i need to know asap. Will this fit on a 1\4 tube
Answer: I answered incompletely because you said ASAP. The true answer is that 1/4 = ~6mm. A hose that has been advertised as 1/4 will probably accept a 10mm fitting given proper conditions. (gentle heating, etc)
Question: What is the approximate amount of volume required to bring the solvent level above the inner tube of the trap
Answer: It's about 25 ml
Question: Could these fit in a test tube holder or do they have to be clamped
Answer: I have always used these with a clamp and I have never seen one in a test tube rack, but I suppose they would fit in a particularly large rack, possibly one for 50mL Falcon tubes. Remember that this trap is over 1 inch in diameter. I would personally recommend a clamp unless there is a specific reason for using a test tube rack - a cheap clamp and stand are less expensive than this trap.

User questions & answers

Question: vacuum connection size
Answer: It looks like it will fit. I checked the numbers against the one I purchased and it said that the B1172-06 would fit your Gms80804bn furnace. They are pretty standard, it just depends on whether the old one is bent or straight and how long the rod is.
Question: What else would I need other than material to get started with this system
Answer: Will not work on all Goodman models. Bought for GUA100A model and will not match to screw hole or length of original.

BACOENG 1.2 QT Stainless Steel Resin Trap Vacuum Degassing Chamber (3 Gallon/1.2 QT/2 QT Available) …

BACO ENGINEERING

Based on 15 reviews Check latest price

Product description

Protect your equipment! These vacuum-sealed tanks are installed in the vacuum bagging process between the mold and the vacuum pump to capture excess resin that enters the vacuum line before it can damage your equipment. Resin traps are an integral part of all vacuum infusion and vacuum bagging processes. Our Stainless Steel resin traps come equipped with clear lids that allow you to easily monitor resin accumulation.

Safety Information:

If large amounts of mixed resin remain in the feed pot or accumulate in the catch pot, the resin can become very hot indeed. In extreme circumstances, the resin can actually start smoking as it reaches very high temperatures.  

Keep an eye of the catch pot and wait for the exotherm to die down. 

TIPS:

Apply mold release to all interior surfaces of the resin trap prior to lay-up for easy clean-up once the vacuum process is complete.

Additional containers can be placed in the large 3 gallon tank to collect the resin.

This Kit Includes:

  • 1 × Stainless Steel Pot
  • 1 × Clear Lid
  • 1 × Glycerin-filled Gauge
  • 1 × Air Manifold
  • 1 × Resin Catch Hose
  • 1 × Vacuum Hose

Chamber Size:

  • 3 Gallon 9.8"(ID) × 9.8"(H)
  • 1.2 QT, 4.3"(ID)× 3.9" (H) 
  • 2 QT, 5.1"(ID)× 4.3" (H)

  • Resin Traps come complete with glycerin-filled vacuum gauge, fittings for use with 1/4" vacuum tubing,brass ball valve and instruction manual.
  • Capture excess resin and protect your pump! Measuring range of vacuum gauge：0-29.25inHg
  • Unique Catch Port Design: An additional hose can be installed at the port inside the tank to facilitate accurate collection of resin.
  • 5 Feet Reinforced Vacuum Hosing Connect Directly To Vacuum Pump 1/4" SAE.
