No, you can also work with Combitips that are not completely filled. Please note that the 1st dispensing must also be discarded in this case.

Can Combitips advanced be used in food analysis?

The materials used to produce Combitips advanced (50 mL, 25 mL, 10 mL, 5 mL, 2.5 mL, 1 mL, and 0.5 mL) are compliant with the requirements on materials used for articles or components of articles intended to come into contact with food.

Are Combitips advanced resistant to nonane and dodecane?

The Combitips advanced are resistant to nonane and dodecane to a limited extent. We recommend using these chemicals with extra caution and at your own risk. Do not dispense the chemical for a longer period than 10 minutes with the same Combitip advanced, and then change the tip to avoid loss of precision or damage to the piston inside the tip.

Are Combitips advanced resistant to acetonitrile?

Yes, however bleaching of the scale could occur in the long term.

Are Combitips advanced resistant to acids?

Combitips advanced are resistant to most moderate inorganic acids. For example, 10% nitric acid, 60% sulphuric acid, 40% hydrofluoric acid, and 35% hydrochloric acid can be taken up without damaging the Combitip and can be dispensed over a period of several weeks. We are not, however, able to give any information about dispensing accuracy or functionality of liquid dispensing. Also, we are not able to make any generally applicable statements for organic acids since the resistance varies considerably, depending on the acid. For example, the Combitip advanced is resistant to 50% acetic acid at room temperature, but not to butyric acid.

Are Combitips advanced resistant to trifluoroacetic acid?

This substance was tested separately. The test result for trifluoroacetic acid with a concentration below of 50% shows that Combitips can be used. Therefore higher concentrated trifluoroacetic acid (größer 50%) the resistant is dependent on the exposure time.

The primary components of petroleum spirit are pentane, hexane, and octane. Because the secondary components are unknown, we cannot guarantee that the Combitips advanced are suitable for your application. However, we would be pleased to send you a sample of the Combitips advanced to try out.

What are Combitip Racks made of?

The Combitip Rack is made of polypropylene (PP) and is autoclavable

When must the Combitips advanced advanced adapter for 25 ml and 50 ml be changed?

We recommend cleaning and disinfecting the adapter after each use. Then it can be used for up to 25 Combitips, since there is one new adapter in each package of Combitips advanced.

Yes, Combitips advanced are produced without using slip agents. There is a batch-independant certificate available.

Is there a certificate available regarding trace metals?

Yes, there is a lot-unspecific certificate regarding the absence of trace metals available.

Is there a certificate available regarding slip agents (including oleamide, erucamide, stearamide),biocides (including DiHEMDA), plasticizers (phthalates) and BSE/TSE free?

Yes, there is a lot-unspecific certificate regarding the absence of slip agents (including oleamide, erucamide, stearamide),biocides (including DiHEMDA), plasticizers (phthalates) and BSE/TSE available.

Can Combitips ® advanced be used for dispensing high-proof alcohols?

Yes, Combitips ® advanced can be used to dispense high-proof alcohols. Using the 5 mL and 10 mL Combitips ® advanced tip sizes with ≥70 % alcohol the dispenser tips have to be prewetted once with the solution. This volume has to be dispensed including the remaining stroke.

특징

Eppendorf의 Multipette^® 멀티 디스펜서 피펫을 이용할 때의 팁 선택

혁신적인 디자인이 적용된 Combitips advanced 디스펜서 팁은 실험실에서 작업할 때 많은 이점을 제공합니다. 통합 피스톤을 사용하면 직접 치환 방식으로 작동하며 작업하는 액체의 물리적 특성(예: 점도, 휘발성, 밀도, 온도)에 관계없이 정확한 양의 액체를 분주합니다. 따라서 액체의 특성에 관계없이 고정밀 분주를 할 수 있으며, 에어로졸 오염을 방지하는 밀봉된 피스톤 덕분에 방사성 또는 독성 물질을 안전하게 처리할 수 있습니다.

Eppendorf는 1978년에 Multipette/Combitips 멀티 디스펜서 시스템을 최초로 개발하여 지금까지 여러 차례 개선했습니다. 사용자가 팁을 한 번 채우고 여러 번 분주할 수 있는 최초의 피펫팅 시스템이었습니다. 이 시스템은 플레이트 또는 일련의 튜브를 이용하는 많은 실험실에서 반드시 필요한 고효율 액체 처리 기기로 사용되고 있습니다. Combitips advanced 피펫 팁 제품군은 2023년에 비영리 단체 My Green Lab^®의 ACT^® Environmental Impact Factor Label 인증을 받아 더욱 지속 가능한 제품을 원하는 실험실에 이상적인 선택이 되었습니다.

MultipetteM4 멀티 디스펜서 피펫을 이용한 분주 용량 조절

Eppendorf의 Multipette M4 및 Multipette E3/E3x 멀티 디스펜서 피펫은 모두 Combitips advanced 직접 치환 피펫 팁과 완벽하게 조화를 이룹니다. 사용하는 Combitips advanced 팁에 따라 1 µL~10 mL 범위에서 다양한 분주 용량을 손쉽게 선택할 수 있습니다. Combitips advanced 팁별로 20단계의 분주 용량을 설정할 수 있습니다. 최대 용량으로 채워진 Combitips advanced 팁으로 5~100단계 용량을 분주할 수 있습니다. 아래 "매뉴얼"에서 다운로드할 수 있는 기술 데이터시트를 통해 자세히 알아보세요.

여러 가지 용량과 Purity Grade 중에서 선택할 수 있어 다양한 작업에 적합

9가지 용량(0.1 mL~50 mL)과 4가지 Purity Grade(Eppendorf Quality, PCR clean, Biopur^®, Forensic DNA Grade) 중에서 선택할 수 있어 항상 작업에 맞는 완벽한 Combitips advanced를 찾을 수 있습니다!
