Their construction is entirely made of polypropylene making it resistant to most aggresive substances like acids or alkalis. Connecting the cabinet to the fume hood ventilation system guarantees safety for people working in the laboratory. The fronts of the cabinet move along a guide made of polypropylene, one shelf divide the interior of the cabinet into two levels. PVC cuvette is included in delivery. The cuvette protects from uncontrolled leachates which will make it easier to keep the inside of the cabinet clean.
