This instrument is designed for laboratory usage only. Please read this manual carefully before
installing and operating. The instrument shall not be modified in any way. Any modification
will void the warranty and may result in potential hazard. We are not responsible for any injury
or damage caused by any non-intended purposes and modifying the instrument without
authorization.
1. Check the voltage specified on the name plate and ensure it matches the line voltage in
your location.
2. Install the instrument in a clean, dust-less and ventilated area under 40°C.
3. Never use the instrument with any flammable or toxic material.
4. Never use instrument with chemical material, except for Lafil 300C.
5. The instrument is not designed to start against applied vacuum. To prevent damage, verify
that the pump inlet is at atmospheric pressure before each start. If necessary, the inlet can
be vented to atmosphere by partially unscrewing the vacuum regulator knob.
6. The pump has a thermal protection device that automatically shuts-off when it becomes
overheated.
7. Do not use any lubricant, which may damage the pump.
8. Filtration accessories, including overflow protection, are applicable to most of low
concentration acid, base, organic solution but not all solution. Please search for chemical
compatibility chart before using.
9. Please discard packing material according to local related regulations.
* Warning: The PTFE-coated diaphragm and chamber in Lal 300C can oer good resistance
to a wide range of chemicals except strong acid and alkali.

Vacuum Filtration System Operation
A. Turn on the pump, block the inlet and regulate the desired vacuum by vacuum regulator.
B. Put the installed filtration apparatus in Lafil series vacuum pump.
Insert the silicone adaptor onto bottom of laboratory glass bottle of LF 5a -500 or VF 12, then
install filtration apparatus into vacuum pump to stable the system.
C. Connect the inlet of pump and filtration apparatus with silicone tube as shown below.
D. Place the membrane in filter holder, pour sample liquid and turn on the pump to start
filtration.
E. After finishing filtration, turn off the pump and retrieve the membrane.

1. The vacuum pump is not autoclavable. Please clean the surface by pure water or 75%
ethanol.
2. After finishing the experiment, please keep pumping the air for at least 2 minutes to
withdraw the residual steam.
3. Filtration apparatus and accessories are autoclavable (121°C, 1 bar, 20 min).
4. Please make sure to rinse apparatus with pure water and separate each part before
autoclave.
5. DO NOT autoclave the plastic filter holder with aluminum foil. It is always recommended
to autoclave the funnels in autoclave bags.
6. Funnels, adaptors, and membrane supports of SF 10 are made of SS316 which can be fast
sterilized by flame or autoclaved.
7. O-ring(s) and silicone tube(s) are consumables, it is recommended to replace it on a yearly
basis or as needed to ensure good operation.
8. When replace fuse on Lafil 300 / 300C / 400, get the spare fuse from the fuse holder.
(4A fuse for 110V; 1.5A fuse for 220V)
