Durability

HTL equipment is built to last. Our company was one of the first in the industry to introduce 3 years warranty covering the pipettes. We did this years ago because we were confident of the performance of our products even after long and extensive usage. In fact if HTL pipette is used and maintained in accordance with its manual it would last a lot longer than declared 3 years*.

Solid components

HTL pipettes base on well proven constructional concept of the most popular pipettes on the market. The application of solid, but light plastic handle combined with highest grade steel components (calibration screw, springs and low volume pistons) results in high mechanical and chemical durability of our products. There is no pipette which would withstand all chemical and mechanical hazards, but the experience of our dedicated users show that in the most severe environment HTL pipettes shall last longer than plastic or aluminum products of most of other manufacturers.

Robust Shafts

– breaking shafts is the most common problem faced by all professionals working with the pipettes. When pipette is dropped or swung during tip sealing, the breakage may occur. All newest versions of HTL pipettes (LAB MATE⁺, MULTI MATE⁺, CLINIPET⁺, DISCOVERY⁺, EPA PLUS^®, V3) are equipped with the shafts manufactured of PVDF. This space age material guarantees highest mechanical durability of the shaft and and lowest durability deterioration under the influence of commonly used aggressive substances. In order to make sure tha only shafts of the highest robustness parameters are assembled with our pipettes we introduced a frequent shaft durability test to the range of tests applied during our quality control procedure.

UV resistance

HTL pipettes are designed to withstand numerous sterilizing cycles. All HTL pipettes can be sterilized with UV beams. Neither reproducibility nor durability of the components deteriorate even after intense and lengthy UV exposure.

Autoclavability

Most of HTL pipettes are resistant to autoclave sterilization. LAB MATE⁺, V3 Series and EPA PLUS^® pipettes are equipped with autoclavable shaft assays. All components (shafts, tip ejectors) of these pipettes which might come in contact with potentially hazardous liquids or vapors can be autoclaved at 121°C 1Bar. It is just enough to unscrew the pipette shaft and put it with all inner components in to the autoclave. Disassembling of the pipette and autoclaving of the shaft assay does not require post assembly calibration.

The DISCOVERY⁺ Series pipettes are designed to be fully autoclavable. Effective autoclaving requires the user only to loosen the shaft nut and put the pipette as a whole to the autoclave. Unlike other pipettes claimed to be “fully autoclavable”, HTL pipettes do not require the calibration check after autoclaving. They would aspirate within declared range after autoclave sterilization without re-calibration. We recommend however that the random checks (every 10 cycles) are performed if the pipette is autoclaved frequently.
