General description:
The Roxtec RS PPS back-to-back seal has been developed specifically to address the challenges of plastic pipes passing through pressurised and fire rated areas. The seal consists of two Roxtec seals that protect against water and gas leakage. An intumescent sealing strip in the middle expands when the plastic pipe burns through, and fills the empty space to stop any fire from passing through.

General description:
Roxtec regular frames are available in different designs and materials. The depth of the frames and modules is 60 millimetres (2.362").
The choice of frame depends primarily on the material used in the construction and the method of attachment. The frames can either be cast, bolted, welded or fitted into sleeves. Frames are also available for use in EMC and EEx applications.

|
General description:
EMC installations are used for shielded transits against electromagnetic disturbances. When using Roxtec B, G, S and SF frames we recommend choosing galvanized versions. If mild steel versions are used, make sure to remove any priming on the inside surfaces of the frames to achieve good electrical conductivity. For casting with B and G frames make sure the frames are properly connected to earth. See casting instructions. Roxtec EMC installations are made together with Roxtec RM ES, PE, ES B or PE B modules.

Junior LB 9509 Portable Tube Luminometer
The Junior is a small portable tube luminometer designed for all common applications using glow-type bioluminescent and chemiluminescent reagents. Excellent performance, its small size and low weight paired with battery operation make the Junior a highly versatile instrument which can be used in any location – the laboratory, on site or outdoors.
Sensitive
The detection unit of the Junior consists of a state-of-the art ultra fast single photon counting photomultiplier with low noise. For demanding applications a “high sensitivity” model with a specifically selected ultra low noise detector is avialable driving the detection limit down to less than 50 amol ATP.
Dynamic
Berthold Technologies single photon counting electronics and selected photomultiplier tubes with low noise and high saturation level ensure a wide dynamic range. The user will benefit by being able to measure low signals as well as high ones without the need to change any settings.
Versatile
The unique design of the measuring chamber allows the use of a variety of different sample tubes and sizes.
Easy-to-use
The lean and dedicated software is operated through a membrane keypad. The well arranged graphical display shows selected protocol, sample locatioon and number and the RLU value of the measurement. In addition a set consisting of a red, a yellow and a green LED unmistakably indicates whether a signal and thus a sample is above an upper limit (red), below a lower limit (green) or in between (yellow).
Applications
Reporter Gene Assays
ATP Monitoring
Hygiene Monitoring
Toxicity of Water Samples
Mycoplasma Detection

Extruded finned tubes
At the heart of most Thermofin heat exchangers’ technology lies Thermofin’s aluminium extruded finned tubes, they are the lead actors on which rests the efficiency and longevity of our units. Their particular design (mono or bimetal) provides great resistance (fin stiffness) as well as exceptional heat transfer characteristics (longevity, temperature range). The mechanical bond joining liner tubes and aluminium wall insures no corrosion occurs between fin and tube, a key factor in permitting the delivery of the specified duty by your heat exchanger, it also offers superior durability.
Heat pipes
Based on Thermofin’s extruded fin tube technology, our selection of heat pipes is designed to suit the need of the Original Equipment Manufacturer. Whether they be bent in ‘U’ shape or equipped with end fitting to facilitate their filling, Thermofin’s heat pipe designs are devoted to match your thermal and geometrical requirements. Their superior thermal performance is partly linked to the fintube inside capillary surface, created during the tube manufacture, this surface promotes the refrigerant migration.
