The importance of laboratory vacuum pumps for short-path distillation

Laboratory distillation system, short-path distillation equipment is a distillation technique involving a distillate that travels a small distance, only a few centimeters away, usually under reduced pressure. Therefore, vacuum pumps are an important device for short-path distillation.
Desktop circulating water vacuum pump, vertical circulating water vacuum pump, rotary vane vacuum pump, diaphragm pump, four vacuum pumps can be used as vacuum pumping equipment in short-path distillation system.

Remark

Can equipped with 2L, 5L glass reactor and rotary evaporator. The vacuum is better when the water temperature is between 4 ºC and 10 ºC.

Vertical circulating water vacuum pump

vertical circulating water vacuum pump

Features

1.One machine with multi-pipe operation, where three sets (five sets )of air exhauster are fixed and can be used independently or parallelly, compared with desktop pump, swept volume is bigger, applied to large swept volume vacuum needs.
2.Corrosion resistance, free-pollution, stable performance, low noise and durable.
3.The tank is made from Polyvinyl chloride plastics, free-pollution; The shell adopts stainless steel material or static spring plastic.
4.Host stainless steel movement and anti-corrosive movement models.
5.The water-line target, light shows high, medium and low.
6.4 trundles make the movement easily
7.The air exhaustor, three links, check valve, suction nozzle are made of PTFE, anti-acid and alkali.
8.Pump body and impeller are made of corrosion protection polypropylene.
9.Special customized motor by well-known manufacturers, fluorine rubber mechanical seal to keep no corrosive gas into the motor.
10.There are several sets pumping system inside the pump. Three or five sets taps are installed in this model, alone or in parallel. 
Compared with desktop pump, it has larger amount of exhaust, in particular suitable for big device’s demands.

Rotary vane vacuum pump

rotary vane vacuum pump

Features

1. The 2XZ series rotary vane vacuum pump belongs to two-stage direct connection structure rotary vane vacuum pump, which can be used for drying, sealing the container and other ancillary pumping air or net vacuum equipment.
2. It has the advantages of small size, light weight, low noise, convenient for using and more.
3. The 2XZ series Rotary Vane Vacuum Pump cannot be used as the compression type delivery pump.
4. 2XZ series rotary vane vacuum pump can be used independently, which also can be as the booster pump, diffusion pump, molecular pump, and titanium pump's pre-pump. Also used as electronic devices produce, vacuum drying, filtration, welding, metal smelting, etc.
