Manufacturer: Bürkle Model: Gas-tight stainless steel barrel pump discharge hose/stopcock P/N: 5611- (more)1090 Description: Gas-tight barrel pump is a pump with flexible discharge hose for filling off into large canisters and containers. It provides convenient transfer because the canister can stay on the floor. The connection cone is held onto the container. The gas-tight barrel pump enables odour-free transfer. During transfer with normal pumps, it is impossible to prevent vapours escaping into the atmosphere. The gas-shuttle method avoids this. Any vapours produced are returned from the container which is to be filled to the original container via the gas-shuttle pipe. The gas pipe and the liquid pipe are additionally provided with stopcocks. Gas-tight pumps are used for substances that have a strong smell such as ammonia. Not suitable for acetone!Please note: When withdrawing flammable liquids, the barrel and pump has to be grounded! Use Anti-static set!Features: - Parts in contact with media: Stainless steel AISI 304 (1.4301), PTFE, nickel-plated brass, PA that can conduct electricity- Incl. gas-tight barrel screw joints with 2" fine thread- For bottle openings from 16–49 mm- Immersion tube Ø 32 mm- The pump can be hermetically sealed with two ball valves Specifications: - Immersion depth: 57 cm- Total length: 69 cm- Pump capacity: 350 ml per stroke Items delivered: - Bürkle Gas-tight stainless steel barrel pump discharge hose/stopcock Condition: The pump is in excellent like new cosmetic condition.

Edwards RV5 Vacuum PumpFeatures - The RV is a truly versatile pump for operation throughout for your (more) operations, perfect for wet applications, dusty applications and clean dry applications. - The RV series of pumps has the highest vapor handling capacity of any rotary vane pump. This is ideally suited for your wet pumping applications such as freeze drying, extraction, filtration and gel drying. - The best-in-class anti-suck back protection prevents dust or oil mist from entering your system. The fast-acting automatic inlet valve acts within 0.4 seconds. - The universal motor in the pump covers the widest possible voltage and frequency range from a single motor. - You can service and replace parts without dismantling the pump mechanism. All parts self-align, eliminating the need for special assembly. Pump valve has "controlled" opening on power startup so that the system vacuum will never see a pressure surge on startup The RV uses a high-quality "universal" motor to cover the widest possible voltage and frequency range. A one-size Allen key is used to dismantle all parts of the RV pump. All rotor and stator parts are completely interchangeable The RV series of small oil sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapour handling capabilities with quiet operation. With over 300,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. All RV pumps are approved to UL and CSA standards by an external test house and feature our unique mode selector switch, meaning one model is suitable for both high vacuum or high throughput applications.Click Here to View Product Video INCLUDED: The Edwards RV5 Rotary Vane Vacuum Pump includes: - Edwards Ultragrade 19 Oil - Power Cord - Manufacturer's Documentation - Operator's Manual - 1 Year Manufacturer's Warranty

PS.R2 series balances represent a new standard of precision balances. They feature a new, readable L (more)CD display which allows a clearer presentation of the weighing result. Besides, the display has a new text information line allowing to show additional messages and data, e.g. product name or tare value. Communication interfaces New PS.R2 balances, like previously designed PS series balances, have pans in two possible dimensions: 128x128 mm or 195x195 mm balances with a smaller pan have a draft shield. The balance precision and the measurement accuracy is assured by automatic internal adjustment, which takes into consideration temperature changes and time flow. PS.R2 balances feature several communication interfaces: 2 x RS 232, type A USB, type B USB and optional Wireless Connection. The balance may cooperate with computer by means of USB interface supposing a supplementary software has been installed (respective driver). The said driver may be downloaded from RADWAG website – SOFTWARE link or SUPPORT section. The housing is made of plastic, and the pan is made of stainless steel. The balances have a possibility to weigh products out of the pan (under-pan weighing) - the load hangs under the pan. Databases in R Series Balances The information system is based on 5 databases, which allows for several users to work with several products databases, and the registered weighing results can be subject to further analysis. The data is registered in 5 databases: users (up to 10 users), products (up to 1000 products), weighments (up to 5000 weighments), tares (up to 100 tares), ALIBI memory (up to 100 000 weighments). Quick access to information There is two directions data exchange within the system thanks to a quick USB interface. New balances allow to import and export databases using USB pen drives. Direct access to functions and databases is possible from the level of keyboard. Database - a direct access to databasis Function - a direct access to the basic functions F1 do F4 - programmable function and navigation keys on the menu ALIBI memory The used ALIBI memory is a data secure area and allows to record up to 100 000 weighment records. It ensures security of constant data register in the long time period. Under-pan weighing Weighing instruments purchased after 15th February 2023 will allow under-pan weighing at any time after the purchase. All you need to do is just to order a dedicated hook.
