Customer Care

The design of HTL pipettes bases on decades of experience and reflects our deep understanding of end users needs and preferences. Within the years HTL representatives have paid hundreds of visits to all kinds of laboratories, on every continent in search for the most optimal characteristics of the manual liquid handling tools. This never ending research work of our dedicated distributors and our marketing crew allows us to find an ideal equilibrium between pipette weight, materials applied, forces necessary for smooth but precise pipetting as well as the pipette handle shape.

Extensive pipetting is a hard physical work which in some extreme cases may cause Repetitive Strain Injuries (RSI). While crafting our pipettes we made sure that their properties give the user the sensation of comfortable work with the most popular pipettes on the market, but at the same time they minimize strain and potential risk of RSI.

The most important pro ergonomic features of HTL pipetting systems are:

• Low pipetting forces
• Carefully designed handles
• Low tip ejection forces 
• Convenient volume setting system

Smooth Pipetting
The pipetting forces of all HTL pipettes belong to the lowest in the industry. Our research work of the last 3 years was aimed in particular at pipetting force reduction. The newest models of our pipettes (DISCOVERY Comfort Series, LABMATE Soft, and CLINIPET⁺) feature low tension springs as well as smoothly running plunger sealing system resulting in effortless pushbutton operation at both pipetting and blowout stages.

Handles Designed to Fit Every Palm
HTL LABMATE Soft pipettes are renowned for their convenience and the sensation of the "familiar feel". While the pipette feels in the hand as the most popular pipettes on the market it offers wide finger support allowing for convenient hanging of the pipette on the index finger and relaxed grip. The weight of the LABMATE Soft (lower than of the popular pipettes) gives the laboratory professional an optimal balance between low strain and secure pipette handling. 

The newest DISCOVERY Comfort Series Pipettes inherit all benefits of the LABMATE Soft, offering additionally slimmer pipette handle, fitting even for the smallest palms as well as new pipette and ejector pushbuttons. The diameters of the pushbuttons, together with their smoothly shaped edges ensure comfortable handling regardless of the thumb length and prevent squeezing the skin or the glove in between the pushbutton and pipette handle.

Anti - squeeze ejector button of DISCOVERY Comfort pipettes

The hollowed finger rest of the DISCOVERY, together with their slim handle were designed to get rid of spare grams of plastic which can mean so much after hours of intense pipetting.

The fixed volume CLINIPET⁺ pipettes were designed exclusively as the fixed volume Pipettes. Their handles carry only the components necessary for accurate work of the fixed volume pipette, thus they are slimmer and lighter than most fixed volume pipettes of other manufacturers. The CLINIPET⁺ pipettes are equipped with a unique tip ejector button. The ejection is performed by sliding the button to the left or right. This effortless movement offers relief to the tendons of the thumb worn out during ejection of the tips with other standard pipettes.

Retrievable shafts in DISCOVERY Comfort multichannel and CLINIPET⁺ pipettes

Low Tip Ejection Force
HTL pipettes are equipped with a number of systems aimed at reducing the force of tip ejection.

The revolutionary system applied by HTL for reduction of the tip sealing and ejection force bases on the concept of retrievable shafts and cones. During the sealing of the tip on the pipette the pipette is being pressed against the rack of the tips. When the pressing force applied to the pipette is sufficient for secure sealing the shaft starts to retrieve inside of the pipette body, preventing tip jamming. Thanks to this unique, patented system the tip is being sealed with the minimal force and the force necessary for tip ejection is respectively small. The system of retrievable shafts is applied in DISCOVERY Comfort multichannel pipettes as well as CLINIPET⁺ fixed volume pipettes.

The system of precise setting of the tip ejector stroke in other models of HTL pipettes allows ejecting the tip with minimal effort and only after the Minimal movement of the thumb on the ejector pushbutton.

Convenient Volume Setting System

While designing the volume setting system in our variable volume single channel and multi channel pipettes we wanted to make sure that the location of our volume setting knob is proper for convenient one handle operation and that the knob rotates smoothly allowing for precise volume adjustment.

DISCOVERY Comfort Series and LABMATE Soft pipettes feature dual volume setting system. Pipette volume can be set precisely with one hand, by the turn of the volume setting knob. The pushbutton can be used for fast rewinding of the volume counter. The top part of the button is rotational to prevent accidental volume change during pipetting. Additionally the volume setting knob of DISCOVERY Comfort pipettes can be locked by shifting up the locking ring.
