How to Collect Laboratory Waste Liquid Safely?

Time:2020-08-10

In the field of chromatographic analysis, we often use HPLC, UPLC, flow injection and other instruments with mobile phase, which will produce a variety of hazardous waste liquid. How to collect waste liquid in a reasonable way is very important to ensure laboratory safety and personnel health.


In order to solve this problem, Welch has launched a series of products about safety collection in laboratory as following.

          Connect-type safety collection device

This device can be connected with HPLC, UPLC, flow injection and other mobile phase instruments to directly discharge the hazardous waste liquid generated during analysis to a sealed container. The special feature is that the organic steam filter can remove the pressure inside the container and filter the harmful volatiles. Different types of liquid level indicators are provided inside the container to remind the analyst to deal with the waste liquid in time.

The standard version of this device includes one 20L certified HDPE waste liquid container, inside and outside caps, one liquid phase connector, one filter quick connector, one liquid level indicator, one inorganic or organic standard filter, and one leak-proof and topping-proof container. In addition, various types are available including high-efficiency, intelligent, desk type, more details are shown in ordering information.


Features of connect-type safety collection device 
◊ intelligent control panel can be installed
◊ can customize security collection kit based on customer waste liquid container specifications
◊ container comes with security labels: primary and secondary labels, full reminder

          Dump-type safety collection device

This is a waste liquid collection device which is not connected with the device. Its waste liquid container mouth is equipped with organic vapor filter which can remove the pressure inside the container and filter the harmful volatiles. Different types of liquid level indicators are provided inside the container to remind the analyst to deal with the waste liquid in time.

Standard dump-type safety collection device mainly includes one 20L certified HDPE waste liquid container,  inside and outside caps, one splash-proof filter net with cap, one waste liquid funnel, one liquid level indicator, one set of filter quick connector, one inorganic or organic standard filter, and one leak-proof and dump-proof container. In addition, various types are available including high-efficiency, intelligent, desk type, more details are shown in ordering information.


Features of standard collection device:
◊ PP funnel with splash-proof filter net set inside
◊ UN authenticated container
◊ funnel with valve switch
◊ liquid level indicator, acoustic and optical alarm, intelligent control panel are all available for various security mechanisms

◊ organic, inorganic and acidic filters are available to ensure safe collection of various waste fluids


Features of desk-type collection device:
◊ PP funnel with splash-proof filter net set inside
◊ install through the open hole on the experimental table, connected by the PFA hose, placed either under the experimental set or in the fume hood.
◊ intelligent control panel can be installed
◊ organic, inorganic and acidic filters are available to ensure safe collection of various waste fluids

          Centralized security collection system

More and more users choose to collect mobile phase waste liquid in a centralized way due to the consideration of environmental safety and personnel health in LC laboratory. Through the splint design, the waste liquid pipeline is hidden without destroying the laboratory table. It can transport waste liquid to the designated point in a centralized manner, which is convenient for management.


Features of centralized security collection system:
◊ lifting pipeline to ensure discharge completely
◊ design of outer tube and inter tube, resistant for corrosion and external force
◊ accessories such as inlet joint have longer life

◊ special cooling technology and accessories to ensure sealing

We can provide well pre-sales and after-sales service for centralized security collection system.

          Related accessories for consumables 


HPLC safe injection cap:
◊ equip with PP and PTFE one-way valve, 0.22 µm and 0.45 µm are optional
◊ can be used with either GL45 or GL32 reagent bottles to connect one to four injecting tubes.


Filter:
◊ brand new design of replacement inner core structure
◊ full absorption of harmful gas to avoid leakage
◊ A variety of filtration materials are combined to work better
◊ configuring time tag
◊ saturation indicator is optional 


Filter saturation indicator:
◊ unique material technology
◊ filter saturation, color changing from light to dark
◊ include three saturation indicators for acidic, alkaline and organic gases
Five types of filters including organic, inorganic, acidic, ammonia and methylamine, multi-functional.
◊ with CNAS and CMA laboratory testing reports
◊ unified standard interface
