Explore Chell's precision needle valves for reliable gas flow control. Ranging from 0-20sccm to 0-3slpm, these stainless steel valves ensure the finest gas flow control for pressure or vacuum applications, ideal for gas analysers, chromatographs and mass spectrometers. With smooth opening characteristics and robust construction – including stainless steel and Perlast perfluoroelastomer seals – they're designed to maintain stability in critical environments like mass spectrometry inlet service. #GasFlowControl #NeedleValve #GasHandling

FAQ: What is the maximum operating temperature of a standard FlowSyn system? Answer: To achieve high yield chemical synthesis, precise control over temperature, is a critical factor in achieving the necessary activation energy. Flow synthesis facilitates safe, high temperature reaction conditions not possible in batch reactors. Our standard FlowSyn continuous flow reactor includes two separate heating modules. The coil reactor unit (homogeneous) can be heated to 260°C and the column reactor unit (heterogeneous) can be heated to 150°C. The temperature of each reactor has been calibrated so that the temperature of the solution is accurate to ±1°C. The maximum temperatures are achievable using the stainless-steel coil reactor (260°C). For Teflon and PFA coil reactors the system limits the maximum temperature to 150°C.This ensures that the tubing is not damaged by overheating.

Continuing our dive into the world of cryogenics, let's consider how cryogenic bulk storage tanks are filled. Unlike an atmospheric storage vessel, where you can fill the tank with liquid and any gas above the liquid level can vent away, cryogenic liquids are stored under pressure to prevent excess boil off. Cryogenic tanks come standard with a single inlet connection for a delivery truck, but valving to direct that inlet into the top and/or the bottom of the tank. Let's consider how these are used. 1. The Traditional Top Fill Method Filling into the head space of the tank is the fastest and most common method used. However, when fresh liquid comes into contact with the comparably warmer gaseous headspace, pressure in the headspace falls due to the rapid cooling. This can lead to a drop in gas supply pressures during the filling operation. 2. Simultaneous Top and Bottom Fill The solution to maintaining gas supply pressures and still having an expedient tank fill is simultaneous top and bottom filling. The operator will allow cryogen to flow into the bottom of the tank, which compresses the head space, and to flow into the top of the tank, which reduces pressure in the head space. This is accomplished normally with two manual globe valves at the tank filling connection, which the operator adjusts as needed to maintain tank pressure. Also, if you ever find yourself needing to fill these tanks, especially if they are empty, make sure you chill in your transfer equipment and the tank itself slowly. Occasionally, the tank supplier will have guidance on the target tank chill down rate. No need to have a very bad day because you were impatient. #cryogenics #processengineering #mechanicalengineering

Why use the Frontier Micro-Furnace Pyrolyzer? 1. Sample treatment at high temperatures when others cannot. 2. Allows multiple analyses on a single sample (liquids or solids) without the need for solvents and sample preparation; the sample is simply introduced into the GCMS by the Frontier Pyrolyzer, reducing the time and resources required before analysis. 3. By eliminating sample preparation steps, it enhances the precision of quantitative analysis, ensuring more accurate results. Furthermore, with no solvent extraction involved, it reduces the risk of sample contamination, maintaining data integrity and reliability. 4. Offers multiple configurations for analyzing samples using different techniques such as evolved gas analysis, thermal desorption, flash pyrolysis, and many more. #FrontierPyrolyzer #Pyrolyzer #LabEquipment #HighTemperatureAnalysis #SampleAnalysis #NoSolventNeeded #QuantitativeAnalysis #DataIntegrity #SampleContamination #MaterialAnalysis #GCMS #AnalyticalInstruments #EvolvedGasAnalysis #ThermalDesorption #FlashPyrolysis #PrecisionAnalysis #ReliableResults #LabEquipment #FrontierLab

When it comes to LNG service, it is imperative to select cryogenic ball valves of the double-isolation-bleed (DIB) type 1 or type 2. These valves are specifically designed to meet the demands of cryogenic applications. Liquid nitrogen cryogenic treatment is an integral component of the manufacturing process for cryogenic ball valves. To ensure optimal sealing performance of the packing box and the smooth operation of the #ballvalves, extended bonnets and drip trays are employed in our designs. In order to better understand the sealing structure of the valve seat, we at #BholaEngineers analyze the characteristics and sealing principles of both the single piston effect seat and the double piston effect seat. The differing sealing directions can be attributed to the distinct structural characteristics of the seal between the valve seat and the valve body. The key performance indicator for #cryogenicballvalves lies in their sealing performance at low temperatures. To ensure this, we subject our #valves to rigorous low temperature simulation tests. Additionally, the type testing of our valves is certified by authoritative organizations, further guaranteeing their reliability and quality.
