Handling liquids in laboratory or during industrial tests, chemical contamination hazards are unavoidable, meanwhile workers suffer repetitive strain in manual liquid handling and samples can easily be contamination hazards through the manipulation of laboratory workers during Pipetting. By implementing cutting-edge design and high-end automation in developing Pipette Dispenser systems to relieve working stress of technicians and reduce the risks for experiment accuracy. Hangzhou Zhongwang Technology Co., Ltd, a National High-tech Enterprise with 80 independent intellectual property rights, focuses on technological breakthrough of liquid handling solutions and provides you lab equipment with safety guaranteed for users and test samples.
Minimizing Chemical and Biological Exposure
Common practices involving manual pipetting often include manipulating dangerous substances. Whether it is exposure to corrosive solutions, poisonous solvents, or biohazards, the dangers are manifold to lab workers who come into close contact, can get splashed with the hazardous chemical, or are aerosolized while working manually.
An advanced pipette dispensing device substantially mitigates the dangers associated with manual methods. The operation of automated dispensers is almost entirely closed loop; this significantly reduces a person’s potential to interact with the chemicals they work with. Some innovative dispensers have entirely sealed liquid paths that protect personnel from coming into contact with the liquid – or anything in the immediate vicinity!
Additionally, the use of some modern noncontact dispense functions means there’s no need for tip submerge and less need for risk of splashing or generating tiny droplet aerosols on draw/eject stages. Pipette automation allows individuals to carry out liquid handling tasks electronically from touchscreen or computer so there is virtually no risk. For applications, like the in synthesis and pharmaceuticals industries or diagnostic and medical labs, this is ideal, since exposure to any hazards has to be minimize.
Reducing Repetitive Strain Injuries
It is well-documented that repetitive manual pipetting poses risks for laboratory workers, in the form of musculoskeletal disorders. Carpal tunnel syndrome, tendonitis and chronic hand pain are all commonly reported as consequences of the thumb movement, static grip and wrist flexion involved in repetitive pipetting actions. Automated pipette dispensers reduce these health risks to a considerable extent.
Their automated nature and ergonomic design are essential to mitigating the risks: Electronic dispensers remove repetitive manual plunger work, substituting them with operation via buttons or touch screen and minimizing mechanical work and force.
The design of the grip on automatic dispensers is also more ergonomic than the standard pipette. Reducing manual and force-intensive activities can, in the case of both High-Throughput Screening and increased volume work, prevent laboratory employees’ pain and also result in lower medical expenses.
Preventing Cross-Contamination and Sample Integrity
Contamination is a prevalent concern in both diagnostic and research environments and since sample fidelity directly correlates to patient’s health and overall data integrity, this is a critical issue to manage effectively. The latest pipette dispensers and automatic liquid handling instruments now come standard with a number of innovations for safeguarding both samples and individuals against potential contaminants. These new liquid dispensing devices have added several layers of defense for preventing cross contamination.
First is a range of filter pipetting tips which act as a barrier to the aerosols and prevent samples carrying over into the rest of the system thereby keeping the inside of the pipette or system uncontaminated.
A further preventative measure on several instruments include the automation to switch pipetting tips in between the liquids, eliminating the chance of contamination in a multi sample system.
