Lemari Asam Polypropelene PT LAB Technologi Indonesia: Your Trusted Partner for Laboratory Design and Engineering
PT Lab Technology Indonesia makes materials the main thing in the fume cupboard body. Polypropylene fume hoods are designed to work with heavy chemicals and have been independently tested, and have test material certification. Test density (DIN EN ISO 1183-1), Flammability ((UL 94), Therman conductivity (DIN 52612-1).
Thus, the description that we have conveyed, hopefully can be a reference for fathers or mothers to have a fume hood or fume hood that is safe and functional.
One of the functions of the Polypropylene Fume hood is to suck harmful gases in the work area. This is useful for protecting laboratory personnel.
The fume hood work area is divided into 2 areas, namely the working process area and the post-working area. The working process area is where laboratory personnel carry out work to prepare analysis, samples and test equipment/preparation in a series of analyses in the fume hood work area.
The post working area is an area where after doing clean work, such as after finishing work there is washing, cooling samples, and so on. The wind speed of the fume hood, or the flow of the Polypropylene fume hood is influenced by these two areas. So as personnel, it is mandatory to understand good laboratory practice and laboratory safety, so that it can be safe and comfortable to work.
How a fume hood works safely
Fume hoods work by sucking air from the fume hood and expelling it out of the fume hood.
The air sucked in comes from the room where the fume hood is stored.
Kemampuan hisapan dihitung dengan prinsip keamanan bagi personel laboratorium, kenyamanan bekerja dalam ruangan, kebersihan area kerja fume hood dan terhindar dari kontaminasi terhadap sampel.
The suction capacity of the fume hood, one of which is regulated in ASHRAE regulation 110 :
2017 in order to protect and maintain the safety of laboratory personnel. In the regulation, the velocity of the fume hood is 0.3 – 0.6 m/s.
Face velocity on the fume hood is influenced by the opening system, buffle, power blower, ducting and others. In working, laboratory personnel need to understand deeply so that it is not detrimental and comfortable in working.
When working with a fume hood, the height of the fume hood door when working needs to be used as a guideline, namely:
1. Tahap preparasi alat, pada tahap ini pintu fume hood dibuka lebih lebar dari tahap bekerja dan stand by.
2. Working stage, this stage is a critical stage, the height of the fume hood door is opened 40-50% of the total height of the door space.
3.Standby reaction stage, at this stage usually the heating temperature, optimal reaction time works, the height of the fume hood door is max 10% of the total height of the door space.
By performing these procedures, it is hoped that laboratory personnel will be safer, more comfortable and more productive.
