Silicone tubing is the softest and most flexible tubing. It is translucent white. Unlike vinyl tubing, there is no plasticizer dissolved in the tubing material. The tubing is pure polymerized silicones with nothing to leach out. This makes silicone tubing suitable for use with most solvents, especially when used at room temperature and with short ( Temperature range – 60 degree C to +200 degree C, odourless, tasteless, inert, resilient, stretchable and resistant to compression set, good electrical and weather ability properties, resists U.V, Ozone, gases and moisture. It`s Applications is peristaltic pumps, hot water feeds, laboratory, food service, beverage service. Silicone rubber tubing sizes start from 0.2mm ID up to 50mm OD and can be supplied in quantities of 10meter.

We deals in double distillation unit In view of calcium & magnesium deposits occurring in primary boiler and the difficulty involved in cleaning these deposits, made us to think of designing the apparatus, so that the primary boiler could be easily dismantled for easy cleaning of calcium & magnesium deposits.

Aqua therm heat exchanger can be used with distillation units. The hot water released from the Condenser outlet is usually let into the Sink, thereby wasting precious water. However, Aqua therm heat exchanger is equipped with cooling coils and fan that cool the hot water as it comes out and then pump it back into the Condenser inlet, thus saving water.   ADVANTAGES It can be mounted on a table to occupy less space. The power consumption is minimal. It takes only 15 liters of water to run the distillation unit(single or double).

The unit consist of a primary boiler with built-in heater. The primary boiler has a ‘O’ ring groove at the top, on which a silicone ‘O’ ring sits. The secondary boiler with condenser is mounted on the primary boiler. A double wall condenser ensures separate condensation of vapor coming from the two boilers using a single cooling circuit. The whole unit is mounted on powder coated stand with electrical terminals for easy connection either to the mains or DAPS (Distillation Apparatus Power Supply) The bottom outlet is connected to a ‘T’ joint of which one limb is connected by a rubber tubing & pinch cock for cleaning sediments in primary boiler by acid wash and other limb to the water leveller of ‘DAPS’.

We offer a wide variety of membrane filter support glassware for most scientific applications that require vacuum filtration. 1. Choose the appropriate support glassware that fits the diameter of the filter membrane you are using (25, 47 or 90mm). 2. Choose the appropriate connection for the flask or bottle you will collect the filtrate in. The following information will help you select the most appropriate glassware for your specific application.   FILTER SIZE 25mm Support glassware is designed for filtering small volumes of liquids in particulate or biological contamination studies. 47mm Support Glassware is recommended when analyzing up to 500 ml. of liquids for particulate or biological contamination, water/waste water analysis (reference: standards methods for the examination of water and waste water, 18th Edition, 1992), sterility testing of pharmaceuticals by the bacteria retentive filter method (reference: U.S. Pharmacopeia XXIII), and for preparing particulate free or sterile filtrates. 90mm Support glassware is recommended for filtering large sample volumes, liquids with a heavy particulate load and viscous liquids when a high flow rate is required. The larger filter area can provide filtration rates up to four times faster than 47 mm assemblies.   SUPPORT STYLE Fritted Glass Supports . Filtration assemblies with fritted glass supports are recommended for general membrane filtration analysis of samples for microbiological or particulate contamination. This support style is recommended when using gridded filters because the glass frit provides the most even distribution of the sample through the filter membrane. All of the fritted glass support bases have a coarse (40-60μm) porosity.   CONNECTION TO FLASK/BOTTLE Silicone Stopper Connections . Silicone or neoprene stoppers are the most common connector from the filtration assembly to a Erlenmeyer style flask and are recommended for most routine filtration studies of aqueous solutions. Stoppers are not recommended when filtering organic or most corrosive solutions or when preparing HPLC mobile phase. Ts 40/35 Glass Joint Connections . Filtration assemblies with Ts 40/38 outer joint connections are recommended when filtering corrosive solutions and organic solvents. This connection style is also recommended when preparing HPLC mobile phase, since the “all-glass” connection eliminates phthalate contamination that can occur when using silicone or neoprene stoppers. 47 mm All Glass Filtration Assemblies with GL45 Thread Connection   Designed to collect the filtrate directly into a media-type bottle.    

A supply of pyrogen free distilled water is basic requisite for many research, analytical & industrial laboratories. Moreover, the materials of the distillation apparatus and storage vessels, should be chosen so as to avoid diffusion of contamination into the distillate. Quartz distillation units are manufactured from imported fused quartz tubes. The exceptionally high chemical purity and very low solubility of this material enables the production of very high performance system. The greatest possible attention has been taken for technical performance, simplicity of use and efficiency.
