Baris 4: == Penggunaan dan keanekaragaman == [[Berkas:RIAN archive 407191 Volgodonsk Nuclear Power Station.jpg\|kiri\|jempol\|~~Para ilmuwan~~Ilmuwan menggunakan pipet di sebuah laboratorium di Rusia.]] <!--▼ Pipettes are commonly used in [[molecular biology]], [[analytical chemistry]] as well as [[medical]] tests. Pipettes come in several designs for various purposes with differing levels of [[accuracy and precision]], from single piece glass pipettes to more complex adjustable or electronic pipettes. Many pipette types work by creating a partial [[vacuum]] above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense. Pipet biasa digunakan dalam pengujian-pengujian [[biologi molekular]], [[kimia analitik]], juga [[kedokteran]]. Pipet dibikin dalam berbagai macam jenis untuk tujuan yang berbeda-beda dengan tingkat ketelitian dan ketepatan yang berbeda-beda pula, mulai dari pipet beling tunggal sampai ke pipet yang dapat ditala secara kompleks, atau juga pipet elektronik. Banyak jenis pipet bekerja dengan membuat [[hampa udara\|ruang hampa]] sebagian di atas ruang tampung cairan dan secara selektif melepaskan ruang hampa ini untuk menghentikan dan melepaskan cairan. ▲<!-- Pipettes that dispense between 1 and 1000 [[microlitre\|μl]] are termed [[micropipette]]s, while ''macropipettes'' dispense a greater volume of liquid. Two types of micropipettes are generally used: air-displacement pipettes and positive-displacement pipettes. In particular, piston-driven air-displacement pipettes are micropipettes which dispense an adjustable volume of liquid from a disposable tip. The pipette body contains a plunger, which provides the suction to pull liquid into the tip when the piston is compressed and released. The maximum displacement of the plunger is set by a dial on the pipette body, allowing the delivery volume to be changed. Larger capacity tubular pipettes, such as volumetric or graduated pipettes, are used by temporarily attaching a pipetting dispenser.
