The NOWPak Solvent Dispense Module provides convenient and inert sealed dispensing from NOWPak containers. The Solvent Dispense Module (1230H12) contains a gas pressure regulator that delivers adjustable, on-demand inert gas through a cap connector (1230H13 or H14) to the NOWPak or NOWPak II container. Incoming regulated gas pressure of 15 to 55 psig can be used with this system. A manual regulator on the Solvent Dispense Module controls the pressure applied to the inside of the container so that it does not exceed 10 psig for HDPE NOWPak containers or 15 psig for stainless steel NOWPak II containers. Only inert gases such as nitrogen, helium and argon should be used. Pressurized air is not recommended.
As the outside of the liner is compressed, solvent flows through inert tubing to the dispenser valve. Flow rates can be varied from zero to four liters per minute by changing the amount of pressure applied to the container. When pressed, a toggle valve on the Solvent Dispense Module simultaneously opens the gas valve to pressurize the NOWPak container and the chemical valve to initiate solvent flow. Pressure is applied to the container only during dispensing. When the toggle valve is not engaged, solvent flow is stopped and the container automatically depressurizes. The manual regulator also acts as an overnight shut-off valve. As an additional safety feature, a pressure relief valve on the 1230H13 or H14 cap connector ensures the NOWPak container cannot become overpressurized.
Solvent Dispense Module (SDM)
The Solvent Dispense Module regulates flow as well as gas pressurization and venting of the NOWPak container. The 1230H13 or H14 Pressure Dispense Connector is required to complete the Solvent Dispense Module dispensing system.
The Solvent Dispense Module Flexible Extension Nozzle is an The 18” flexible FEP extension nozzle that fits over the Solvent Dispense Module dispenser spout to facilitate filling tall or non-standard glassware.
Solvent Dispense Module Pressure Connectors
The solvent and inert gas tubing and cap assembly connects the NOWPak container to the SolventDispense Module. Each consists of:
• A cap connector with a 3/8” PFA elbow solvent fitting, a 1/4 ” inert gas pressure fitting and a 10 psig (1230H13) or 15 psig (1230H14) pressure relief valve
• An FEP diptube sized for either the HDPE B&J NOWPak or stainless steel NOWPak II container
• A 10’ harness of 3/8” FEP solvent tubing and 1/4” nylon pressure tubing
Four-Place Mounting Bracket Kit
This bracket and hardware kit allows up to four Solvent Dispense Module units or bottletop dispensers to be mounted on a fume hood wall.
Metal Stand and Adapter Plate for SDM
This portable stand and adapter plate holds up to two Solvent Dispense Modules and does not require drilling holes to mount a bracket. When mounted on the stand, the dispenser spout is 19” above the base.
