Product Introduction:

The oil-free vacuum pump has the characteristics of simple structure, convenient operation, high vacuum degree, and long service life. And with good durability, it is a dual-purpose vacuum pump for vacuuming and compression. Wide range of applications; with corresponding equipment, it can be used for aerators, nitrogen blowing instruments, solid-phase extraction instruments, thin-layer color sprays, solvent filters, atmospheric samplers, and other vacuum needs. According to the needs of different operators, filter membranes with different materials and different filter pore sizes are selected. It can remove impurities, purification, and bacteria in the solvent.

Features:

1. Electromagnetic motor and diaphragm seal the gas chamber to ensure one-way gas flow and high vacuum.

2. Non-oil pump design, relatively isolated gas flow in the air chamber, no pollution, safe explosion-proof.

3. The cylinder piston adopts new wear-resistant materials and has a longer service life.

4. The bag shape design makes it easier to use and better heat dissipation. 5. Surface electrostatic spraying, stronger adhesion, resistance to chipping, and discoloration.

Precautions:

  • Do not start with pressure, and it is forbidden to pump liquid into the pump. It is recommended to add a buffer bottle.
  • When using a positive/negative pressure dual-purpose pump, it cannot be used for both suction and inflation.
  • Do not continue to power on for more than 30 minutes.
  • No dust can enter the connecting pipe, and keep the suction pipe clean.
  • Connect the short tube of the connecting tube to the vacuum pump, connect the suction tube to the suction port, and connect the inflation tube to the inflation port. Do not connect the tube reversely.
  • The pump is not suitable for pumping gas that is corrosive to ferrous metals, chemically reacts to the pump, contains particulate dust, and contains too high oxygen and explosive toxic gas. It cannot be used as a transfer pump (that is, pumping from one container to another)

Holy Grail Micellar Water
Size: 13.52 Fl Oz
This is my holy grail micellar water! My skin can be sensitive and reactive at times, and this product has never let me down. It has never irritated my eyes or skin. I use it to double cleanse, although sometimes I use only this micellar water followed by a quick splash of water. It does not leave a film and leaves my skin feeling nourished and happy.

but takes quiet a good amount of cotton balls
Size: 6.8 Fl Oz (Pack of 1)
It removes makeup alright, but takes quiet a good amount of cotton balls. Haven't try it on waterproof makeup yet, but it does make make skin feels clean and isn't harsh. Edit: Tried it for a couple of days, and here's the verdict: It can remove makeup, but you'll need a good amount of it on a cotton pad, and likely you'll use more than one. It feels nice while it is on the face, though it clean best with light makeup, and it takes me a couple of cotton balls to clean eyeliner and mascara. I needed to use moisturizer after it, because it make my skin feels dry. It doesn't take long, and definitely save more time than washing with soap and water, but it's a little bit of a hassle, too. Oh well, at least it's very convenient.

THE Best facial toner period!!!
Size: 6.8 Fl Oz (Pack of 1)
This review is for the 200ml bottle I am one of those few but very fortunate people that isn't allergic to anything, or sensitive to most soaps, cleansers and toners. Unfortunately now that I'm in my fifties my face isn't as fuss free as it once was and soaps and cleansers that were once okay, are now either too harsh for my skin or dry it out. Worse than that are those products that irritate my eyes, especially if they're meant to be used around that area. What gives with these manufacturers whose products are supposed to cleanse your face, but irritate your eyes? Of course sooner or later you're going to get some in your eyes regardless of how careful you are. Which brings me to this amazingly excellent cleanser. A more accurate description of this cleanser would a "cleansing toner" as it's not really a face wash i.e. it doesn't soap or foam up like other facial cleansers. As I'm a guy and don't wear any make up I can't vouch for its efficacy in that department. But I can vouch most enthusiastically for its ability to strip your face clean of excess oil and grime picked up during the day without leaving your face feeling dry or tight. I do use it around both my upper and lower eyelids with zero eye irritation at all. It leaves my face feeling clean and refreshed with only the slightest hint of a clean refreshing smell, so it won't interfere with your perfume or cologne. I use it twice a day as an in between facial cleanser/refresher to eliminate that grimy oily look between my daily showers. Highly recommended for doing an excellent job without irritating or drying out my skin. Try it out yourself as this could be the only skin toner that you'll ever need, and it's reasonably priced too. :)
