Furthermore, the outlet water flow from the water aspirator can be channeled to provide a source of cold water flow for condensers and other apparatuses. The 1.5 segment of tubing was attached onto the outlet barb of the water pump followed by the nylon 3/8 hose barb x 3/8 hose barb elbow, and both were secured with a hose clamp. Integral check valve will also prevent backflow of water into the vacuum line. Also, the water pump will get relatively warm after about an hour of use and it is advised to turn off the power after this time to let the pump cool down. (Sample Photo Shown. A PCB, two 10 ohm resistors, and an aluminum heat sink were soldered together to provide the correct power requirements for the water pump. Meeting the needs of the scientific and engineering communities since 1955. The water reservoir can be modified with specific chemicals to neutralize any noxious vapors or chemicals brought into the water reservoir, depending on the procedure being carried out. The pumps feature a ball-type, positive-action valve in the suction tube which prevents water backflow if the pressure is reduced. bayite 12V DC Fresh Water Pump with 2 Hose Clamps 12 Volt Diaphragm Pump Self Priming Sprayer Pump with Pressure Switch 4.5 L/Min 1.2 GPM 80 PSI Adjustable for RV Camper Marine Boat Lawn (can choose any similar pump that will work, but note voltage, amperage, wattage, and flow rate to correctly assemble the circuit)-purchased from Amazon.com, Nalgene 6140-0010 Faucet Aspirator Vacuum Pump (or any suitable water aspirator), ProLine Brass 3/8 barb x 3/8 FIP adapter, 1 x Nylon 3/8 barb x 3/8 FIP adapter, 1 x Nylon 3/8 hose barb x 3/8 hose barb elbow, 4 x Hex Cap Screws, Class 8.8, M6-1.00 x 20, 4 x Insert Lock Nuts, Nylon Class 8, M6-1.00, 10 Air Hose, 3/8 ID, 5/8 OD (purchased extra just in case), 20 PVC Tubing, 3/8 ID, 1/2 OD (purchased extra just in case), miscellaneous electronics to create a circuit for the power supply, corresponding to the electronic requirements of the water pump (switch, wires, heat sink, blank circuit board, resistors, project box, etc.).

A 6 piece of 3/8 ID, 1/2 OD PVC tubing was placed over the water pump outlet and secured with a hose clamp. It comes with an integral check valve that prevents loss of vacuum when water source is disrupted and prevents backflow. Something went wrong. The tubing was fed into the water outlet hole in the lid of the bucket. The ultimate vacuum is obtained at 28-1/2 inches (723.9 mm) Hg. Initial test and final changes to the tubing configuration: A 5 piece of 3/8 ID, 1/2 OD PVC tubing was placed onto the outlet of the water aspirator and secured with a hose clamp. The 10 length of 3/8 ID, 5/8 OD air hose was secured to the vacuum inlet of the water aspirator. Typically, water aspirators are connected directly to a laboratory faucet (or any faucet) with running water going through the aspirator to create a vacuum. Attach the Nalgene 6140 Polypropylene Faucet Aspirator Vacuum Pump directly to sink faucets for vacuum draw. 4x Nalgene 6140-0010 Faucet Aspirator Vacuum Pump, Polypropylene, 3/8" NPT {"modules":["unloadOptimization","bandwidthDetection"],"unloadOptimization":{"browsers":{"Firefox":true,"Chrome":true}},"bandwidthDetection":{"url":"https://ir.ebaystatic.com/cr/v/c1/thirtysevens.jpg","maxViews":4,"imgSize":37,"expiry":300000,"timeout":250}}. Place the tubing over the water pump inlet and place the hose clamp on the barb and tighten it to secure the connection. This polypropylene aspirator pump attaches to any standard lab faucet to provide maximum free air pumping capacity of 11.5 liters per minute at a water flow rate of 6.5 liters per minute.

Third parties use cookies for their purposes of displaying and measuring personalised ads, generating audience insights, and developing and improving products. The main problem is that using long lengths of tubing connected to a condenser significantly slows the water flow, lowering the vacuum strength. Maximum free air pumping capacity: 11.5L/min. This was placed into the second hole drilled for the water outlet. Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them. The 4.5 segment of tubing was connected to the other end of the nylon 3/8 hose barb x 3/8 hose barb elbow followed by the barb of the nylon 3/8 barb x 3/8 FIP adapter connected to water aspirator. Pump is supplied with an integral check valve 3/8 inch NPT connecting thread and 4.75 inch length of polyethylene tubing for insertion in discharge end. Note: initially a brass barb adapter was installed on the water aspirator, but was changed to nylon to prevent stripping of the threading of the water aspirator. Humboldt Aspirator Filter Pumps offer excellent performance for vacuum filtrations under both high and low water pressure conditions. Please try again. Sorry, there was a problem saving your cookie preferences. This will be used as the inlet filter to prevent particles in the water reservoir from harming the water pump. The opening in the hobby box was covered with micro-pore tape to prevent water from contacting the electronic parts and to allow air exchange for cooling. Integral check valve resists corrosive filtrates and fumes Quick-disconnect hose fitting accepts 6.4 to 9.5mm (1/4 to 3/8") I.D. Don't have an account ? The link to the publication can be found below. Use as a dual water aspirator vacuum pump/circulating water pump: The circulating water of the water aspirator vacuum pump can be utilized to provide circulating cold water to a condenser or other apparatus. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. Attach the Thermo Scientific Nalgene Aspirator Vacuum Pump directly to sink faucets for vacuum draw. It is also important to empty the water reservoir when not in use, as even a few days of keeping the stagnant water in the reservoir led to the formation of mold. Simply put, we can recycle the water and utilize the system for multiple purposes at once. Begin by wrapping the water aspirator threading with 2-3 layers of Teflon tape to ensure a proper seal. We also use these cookies to understand how customers use our services (for example, by measuring site visits) so we can make improvements. However, it worked perfectly for vacuum filtration and small scale vacuum distillation procedures where the apparatus had minimal inner surface area to evacuate with vacuum. In this case, a smaller bucket was chosen for portability. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. Once the circuit was assembled and housed in the hobby box, it was placed on the top of the bucket and hot glued in the chosen location. ALL SIZES. The water aspirator was added to the other end of the 6 tubing and secured with a hose clamp to temporarily test if the vacuum pump worked. Water flow rate: 6.5L/min. This project utilizes two main devices: a water aspirator and a 12V DC diaphragm water pump. Metal aspirator that fits most standard laboratory faucets, Short metal aspirator with " NPT tapered thread, Metal aspirator adapter for 3/8" NPT to standard faucet, Polypropylene plastic aspirator with polyethylene tubing.

After the electronics were mounted to the lid of the bucket, a second hole for the water outlet was drilled in the lid, right next to the water inlet hole. 50/pack, Bada Medical Mask01-D Disposable Face Masks, BrandTech Dispensette S Bottletop Dispenser with Analog Adjustable Volume. The hex cap screws, flat washers, and insert lock nuts were assembled with two washers on each screw. Next, cut an 18 long section of the 3/8 ID, 1/2 OD PVC tubing (change length depending on water reservoir chosen) and ensure that the tubing is long enough to reach the bottom of the reservoir from the the inlet of the water pump where it will be mounted. Nalgene #: 6140-0010. The water outlet was disassembled to change the configuration of the tubing. The apparatus is now complete. ALL MODELS.

Cookies help us deliver our services. It can only be used as a circulating water pump in a small number of applications. Using the circulating water to cool a condenser will lower the vacuum strength somewhat, as the water pressure will be lowered. When configured solely as a water aspirator vacuum pump, an average vacuum strength of 460 mm Hg (+/- 2% error) was achieved with a maximum vacuum strength of 480 mm Hg (+/- 2% error). It also analyses reviews to verify trustworthiness. Upon testing, this 3-D printed aspirator failed to function properly. 2022 Cole-Parmer Instrument Company, LLC.
