Dispensing the exact volume is one of the major concern amongst lab workers handling patient samples and macromolecules such as DNA/RNA, Proteins, Enzymes and other reagents. There are several factors that play an important role in the accuracy of the tests being performed in molecular diagnostics, drug discovery, biological research laboratories and academic institutions handling precious samples and costly reagents. A minor error can lead to a series of false results that may cost the consumer dearly.
Some of the problems that may be encountered due to the Tip Box designs are:
An ideal tip box design must allow easy & unhindered pipette access (especially multichannel pipettes) to all the 96 tips placed inside the box rack, a universal design to accommodate all different brands of pipettes and tips. The shape & dimension of the box along with the accuracy in Lid opening and closure play an important role in handling these steps with precision.
A sturdy Tip Box design solves half of these problems by allowing the personnel to access the tips without toppling the rack and by allowing them to exert enough pressure to uniformly pick the desired number of tips. The sturdiness of the Tip Box is due the robust design and the strength of the material that has been used. A good tip box design must enhance the stability of the rack, and provide equal weight distribution and thereby aid in uniform tip placement leading to equal & consistent aspiration each & every time.
Warping and Shrinkage of the Tip Box is another concern that is again due to the robustness in the design that causes air passage and thereby leads to contamination of the tips.
The new design of Generation 2 Pipette tip box of ABDOS Life Science addresses a few major concerns associated with warping and shrinkage of the box that may lead to contamination. The base of the tip box has also been designed to be sturdy with four ‘L-shaped’ feet at the corners that also enables stackability. The flange & the hinge design on the lid provides the strength to allow the lid to open fully to facilitate unhindered pipette access while picking up the tips from the rack, most importantly while handling a multi-channel pipette. The new tip box can accommodate all types of pipettes & tips according to a 96 well format.
