RCF (nisbiy markazdan qochma kuch) nima?

RCF is the effective force applied to the sample in a centrifuge, expressed as multiples of gravitational acceleration (×g). RCF = 1.118 × 10⁻⁶ × n² × R, where n is RPM and R is rotor radius in mm. Unlike RPM, RCF accounts for rotor size, making it comparable across different centrifuges.

Nega protokollarda RPM o'rniga RCF ishlatish kerak?

RPM o'z-o'zicha namunaga ta'sir etuvchi haqiqiy kuchni ko'rsatmaydi — u rotor radiusiga bog'liq. Bir xil RPMda ishlayotgan, lekin turli rotor o'lchamiga ega ikki sentrifuga turli g-kuch hosil qiladi. Ilmiy protokollar foydalanilayotgan sentrifuga modelidan qat'i nazar takrorlanadigan natijalarni ta'minlash uchun RCF (×g) ko'rsatadi.

Qaysi radiusni ishlatish kerak — maksimal, minimal yoki o'rtacha?

Hisoblanadigan RCF uchun maksimal radiusdan (r_max) foydalaning — bu aylanish o'qidan namuna naychasi tubigacha bo'lgan masofa. Bu namunaga ta'sir etuvchi maksimal g-kuchni beradi. Ba'zi protokollar cho'kish hisoblari uchun r_avg (o'rtacha) ko'rsatadi.

Turli sentrifugalar qanday g-kuchlarga erishadi?

Typical ranges: benchtop microcentrifuges up to 20,000 ×g, general lab centrifuges 3,000–15,000 ×g, high-speed centrifuges 25,000–100,000 ×g, ultracentrifuges up to 1,000,000 ×g. Industrial separators typically operate at 1,000–10,000 ×g.

G-kuchni RPMga qanday aylantiraman?

Use the reverse formula: n = √(RCF / (1.118 × 10⁻⁶ × R)), where RCF is the desired g-force and R is rotor radius in mm. This calculator supports both directions — toggle between 'RPM → RCF' and 'RCF → RPM' modes.

Nisbiy markazdan qochma kuch (RCF)

RCF — namunaga ta'sir etuvchi samarali kuch bo'lib, gravitatsion tezlanishning ko'pligi sifatida ifodalanadi:

n — speed (RPM)
R — rotor radiusi mm da (aylanish markazidan namuna joylashgan nuqtagacha)
1.118 × 10⁻⁶ — combined constant from (2π/60)²/(9.81×1000)

Odatdagi RCF qiymatlari

Application	Odatdagi RCF (×g)	Typical RPM
Qonni ajratish	1,000–3,000	2,000–5,000
Cell pelleting	300–500	1,000–2,000
Oqsillarni cho'ktirish	10,000–20,000	10,000–15,000

Amaliy Misol

Misol — Laboratoriya sentrifugasi

Given: R = 100 mm, Speed = 5000 RPM

RCF = 1.118 × 10⁻⁶ × 5000² × 100 = 2,795 ×g

ω = 2π × 5000 / 60 = 523.6 rad/s

Tip speed = 0.1 × 523.6 = 52.4 m/s

💡 Tip: Ilmiy protokollarda sentrifuga sharoitlari RPM emas, balki RCF (×g) sifatida ko'rsatilishi shart. Bu turli rotor o'lchamlariga ega har xil sentrifuga modellarida natijalarga takroriylikni ta'minlaydi.
