SELECTA GROUP is bound by three additional companies: JP SELECTA, our own brand, COMECTA, representations and AQUISEL, manufacturer of disposable material for single-use analysis. The commercial organisation of the group is channeled through distributors. Here we list a few of our most popular products our clients request. Alternatively view the full brochure below.
ASTM D445 - ASTM D446 - ISO 3104 - ISO 3105. Suitable for transparent liquids.
Complete with calibration certificate.
Total length 283 mm.
Permanent amber markings.
Steam distillation system Kjeldahl, complete with automated “ON-LINE” analysis (evaluation in real time). For systematic precise analysis, with minimum personnel intervention, simple and safe. Adequate for a laboratory with a medium to large throughput of samples.
The Kjeldahl steam distillation unit «PRO-NITRO A» evaluates the distillate at the sa-me time as it is produced ( evaluation «On-Line»), the evaluation and distillation are completed as one operation, reducing drastically the analysis time. This type of eva-luation offers the following additional advantages: detects the point where the sam-ple no longer produces Nitrogen, which means that, the distillation stops at the opti-mum maximum Nitrogen recovery and does not prolong the analysis longer than necessary.
The titration is a colorimetric method and is accepted by AOAC and does not require any periodic calibration.
FEATURES
Distillation by steam generation.
Automatic «On-line» colorimetric evaluation.
Steam generator with safety thermostat, over temperature and over pressure device. Safety, door closed, that prevents distillation if open.
Detects that a digestion/distillation tube is present. This prevents the dosing of NaOH if there is no tube located.
Universal adapter for MACRO (Ø 42 mm) and MICRO (Ø 26 mm)distillation tubes. Space saving in the laboratory: the reservoirs for the H2O, NaOH, Boric Acid and HCl are located inside the unit.
Empties the digestion/distillation tubes and the collector automatically. Automatic stop when distillation is complete.
Large LCD display of 20 x 4 characters.
RS232 output to results printer.
Main system made from stainless steel with an ABS plastic front.
Clinical, biochemical and chemical laboratories. Incubation of DNA, enzyme assays, residual testing in dairy, incubation and fusion of AGAR, cell culture. Thermo control to dry, boiling, evaporation, concentra-tion, hydrolysis, digestion etc.
COMMON FEATURES
Dry block systems have several advantages over wet contact methods such as: no risk of evaporation of he-ating liquid, higher working temperatures, better long term temperature stability and no sample cross conta-mination or germination of bacteria in the bath. Digital temperature calibration. Timer from 1 to 999 minutes or continuous operation. Over temperature alarm. Heating elements are distributed evenly across the con-tact surface maintaining an even distribution of heat.
Easy to use digital temperature and time control with a digital display (3 Digits).
Built in temperature sensor Pt 100.
Interchangeable blocks made of anodised DURAL alloy to accommodate a variety of tube diameters.
(Customer specific sizes also available.)
External case made of epoxy covered steel with an AISI 304 stainless steel top.
FAN ASSISTED CIRCULATION.
BACTERIOLOGICAL ASSAYS, DRYING PROCESSES AND STERILIZATION.
MICROPROCESSOR CONTROL WITH TFT TOUCH SCREEN.
ADJUSTABLE TEMPERATURES FROM AMBIENT +5 °C UP TO 250 °C.
STABILITY: ±0.3 °C, UP TO 100 °C. HOMOGENEITY: ±1 °C, UP TO 100 °C. GLASS DOOR ±2 UP TO 100 °C. SET ERROR: ±2% OF THE WORKING TEMPERATURE. RESOLUTION: 1 °C.
