3. General information
DNA/RNA UV-Cleaner boxes –UVC/T-AR, UVC/T-M-AR, UVT-B-AR and UVT-S-
AR –are designed for clean operations with DNA/RNA samples. They provide protection
against contamination.
All models are bench-top type, with metal framework, glass or acrylic walls and work-
ing surface painted with powder enamel or made of stainless steel. Box is equipped with
inlet for power cables and built-in power outlets for units inside the box. For availability of the
required characteristics, please clarify for each model separately (see 7.1 on page 11).
UV-Cleaner boxes are equipped with an open UV lamp installed in the upper hood.
UV radiation from the open lamps disinfects the working area inactivating DNA/RNA frag-
ments during 30 min of exposure. A digital timer controls duration of the direct UV irradiation.
A daylight lamp provides proper illumination of the working surface.
UV-Cleaner box is equipped with a flowing bactericidal UV-cleaner-recirculator AR,
which provides constant decontamination inside the box during operation. It is recommended
for operations with DNA/RNA amplicons.
UV recirculator consists of an UV lamp (fig. 1/1), a fan and dust filters (fig. 1/2) orga-
nized in a plastic case. Operator working in a UV-Cleaner box with a switched on UV recir-
culator is not exposed to UV radiation. It allows continuous treatment of the airflow with UV
light without interrupting working process. Air circulation at a short distance from the UV lamp
combined with reflective surfaces in the air duct results in increased density of UV rays lead-
ing to higher efficiency of disinfection. UV recirculator generates 100volumes ofPCR cabinet
per one hour of airflow exchange ensuring maximally aseptic conditions inside the cabinet.
Box for clean operations with DNA/RNA samples with built-in recirculator is a pa-
tented solution (patent LV13115 from 20/05/2004, Dr. biol. V. Bankovsky).
Microbiological studies at the R&D Department of Biosan led by Dr. biol. V. Bankov-
sky demonstrated a high level of biosafety and efficacy of UV-cleaner box (maximal level of
contamination is 1-3 cfu per 100 litres of air)
1
.
UV-Cleaner box is designed to biologically protect the product, but not the operator,
therefore, it is not recommended to use the UV-Cleaner box for working with pathogenic
microorganisms of biosafety level BSL-II and higher, without specialized protection.
Advantages:
•UV-recirculator;
•Ozone free high density UV decontamination;
•Open UV lamp is switched off automatically in case of opening the front screen;
•Long life UV lamps (9000 h);
•Low noise level and energy consumption;
•Compact tabletop model for personal laboratories;
•Shelves for pipettes and reagents (on request)
•Table with drawer T-4 / T-4L, laboratory chest of drawers LF-1 (on request).
