Purchase and Import of Liquid Nitrogen Dewar

The Dr. Panjwani Center for Molecular Medicine and Drug Research at the International Center for Chemical and Biological Sciences, University of Karachi, is procuring a Liquid Nitrogen Dewar with a minimum capacity of 240 liters. This procurement is specifically for Karachi and involves the purchase and import of a high-quality vacuumed vessel designed for low pressure liquid nitrogen transfer. The Dewar must be equipped with outboard wheels and a handle made of stainless steel for easy maneuverability, and constructed with high strength 304 grade stainless steel inner and outer tanks. It should feature vacuumed insulation with a high vacuum range from 10^-3 mbar to 10^-5 mbar, comply with DOT 4L requirements, and have a normal evaporation rate of 2% or less per day. The equipment must include automatic and manual pressure relief valves, a differential pressure-type liquid level gauge, a decanting hose of 12 feet length, a standard vent fitting to avoid overfilling, and an adjustable regulator to maintain low pressure. A guarantee of at least two years is required. Eligible bidders must have a complete company profile, valid registration with tax authorities, and a minimum annual turnover at least equal to the bid amount for the last three financial years. Additionally, a minimum of three years relevant experience is mandatory. The bid security is set at 2% of the bid value, and the performance guarantee is 5% of the purchase order value. Bids must be submitted in English and comply with the Single Stage One Envelope procedure as per SPP Rules 2010 (updated 2013). The deadline for submission is strictly by 21st July 2026 at 12:00 PM, with bid opening immediately thereafter. Bidders should ensure their bids are complete with all required documents including the summary sheet, price schedule, and bid security to avoid rejection. A practical tip for bidders is to carefully prepare the bid security and performance guarantee documents as per the instructions, ensuring they remain valid beyond the bid validity period. This will prevent disqualification due to technicalities. Also, submitting bids well before the deadline is advisable to avoid last-minute issues. The procurement process emphasizes transparency and adherence to rules, so any conditional or incomplete bids will be rejected. This tender offers a significant opportunity for suppliers specializing in industrial equipment and cryogenic vessels to engage with a prestigious research institution in Karachi.
