Pioneer Scientific Instrument Corporation

PIONEER SCIENTIFIC INSTRUMENT CORPORATION providing Vacuum filtration of Tissue Culture media, components, Biological Fluids, HPLC and other aqueous solutions. Filter units contain an integrally sealed fritted glass support bed (perfectly ground to match a funnel) for holding a 25 mm. /37 mm. /47 mm. dia. Filter membrane (not suitable for Ceramic Membranes). The unit is designed to maximize flow and reduce foaming and protein denaturation. The filter funnel support bed and receiver flask are fitted with interchangeable ground joint and one Aluminium Clamp is provided to hold the filter funnel and support bed properly. One dust cover made of polypropylene is also provided.

The total unit is autoclavable
Another model is available with silicone rubber stopper (which can withstand repeated autoclaving) fitting in place of ground joint fitting.

Pisco Screw Capped Glasswares are ideal for laboratory culture work. Free interchange between the atmosphere inside and outside the mouth of the glassware, completely satisfying the gas requirements for aerobic culture, is easily attained by slightly loosening the caps. Can withstand repeated autoclaving since the liner used in it is made of pure silicone rubber with PTFE facing.

Available in 3 models with different sizes :

• Culture Tubes, R.B./ F.B., Cat. No. T-80 : 5 ml., 10 ml., 15 ml., 30 ml. and 60 ml.
• Conical Flask, Cat. No. T-40 and 575b : 10 ml., 25 ml., 50 ml., 100 ml., 150 ml. and 250 ml.
• Bottles, Cat. No. T-10 and 442c. : 10 ml., 25 ml., 30 ml., 50 ml., 60 ml., 100 ml., 125 ml. and 250 ml.

PIONEER SCIENTIFIC INSTRUMENT CORPORATION is a highly renowned name involved in the exporting and fabrication of superlative quality Sintered Filter Discs.

The glass fiber structure of PISCO sintered filters and results in a more abrasion resistant surface. Being fused together on a greater surface area, the particles do not detach from the filter body as easily as spheroid granules. Being made entirely of heat resistant borosilicate glass, resistance to thermal shock and chemical attack is unimpaired. PISCO sintered filters are manufactured from 100% low expansion borosilicate glass grains, cleaned, and 100% chemically pure. PISCO sintered filters are extensively used for the filtration of both liquids and gases.

Features :

• 100% chemically pure
• Extensively used for the filtration of both liquids and gases
• Customized designs and specifications are welcome
• Available in a host of sizes and dimensions

Applications :

• Medium filtration & washing of gases
• Analytical work
• Collection of fine precipitates
• Gas dispersion.
