How can Brinkmann^TM Help ?

As a laboratory technician, pipetting is a routine laboratory technique that is performed everyday, for a good portion of the day. Pipetting work demands concentration, accuracy and precision. Due to the nature of the tests being conducted, only short breaks can be taken due to time restraints to achieve optimal test results (Friedriksson 1995). Cumulative trauma disorders have become a concern of laboratory technicians since the 1960s when plunger operated mechanical pipettors were first introduced. The switch from bulb operated glass pipettes to mechanical pipettes introduced a repetitive movement that was not used for liquid handling in the past. With the increased numbers of experiments that are required in a normal laboratory setting today, the reports of cumulative trauma disorders have also been increasing.

According to a study conducted in Sweden, technicians who were performing pipetting techniques for more than 300 hours a year had a higher prevalence of hand ailments (Bjrkstn, 1994). This equates to a daily routine of 12 hours a day of pipetting tasks. The features of the pipette, such as the design of the plunger, weight and length of the pipette, force needed to operate the pipette, and how the pipette fits into the hand, (Yltupa 1997) may also increase the risk of cumulative trauma disorder.

With the increased focus on reducing any types of repetitive stress injuries, many pipette manufacturers and health organizations have looked at this field and analyzed causes and possibly preven
