Kofloc RK1250 Flow Meters and Controllers for Liquid: Efficient Superior Flow

Description

Kofloc RK1250 Flow Meters and Controllers for Liquid as a successor to the RK1200, the Kofloc Model RK1250 offers improved visibility and a more modular design. For liquid applications, it specializes in handling “trace flows”—from ultra-minute 0.5 mL/min up to 1 L/min. The core of the RK1250 is its non-rotating precision needle valve. Unlike standard valves that rotate against the seat (causing wear and drift), the RK1250 needle moves purely in a linear motion. This preserves the seat’s integrity and allows for highly repeatable, delicate adjustments. The block is typically made of SUS316 Stainless Steel for liquid use to ensure zero corrosion, and the glass tube is protected by a transparent acrylic cover for operator safety.

Kofloc RK1250 Flow Meters and Controllers for Liquid: Efficient Superior Flow are high-grade, precision-manufactured instruments designed for the accurate measurement and regulation of small liquid flow rates. Utilizing a high-visibility tapered tube and a precision-ground float, the Kofloc RK1250 Flow Meters and Controllers for Liquid provide an efficient and stable visual reference for liquid movement. Engineered by Kofloc in Japan, this model is a superior choice for researchers and engineers who require the utmost reliability in their fluid management systems.

Why the RK1250 Series is the Best Investment

Choosing the Kofloc RK1250 Flow Meters and Controllers for Liquid is an efficient move for any operation that cannot afford flow variance. In precision fluidics, the most superior way to ensure data integrity is to use a flow meter with a proven mechanical history. The Kofloc RK1250 Flow Meters and Controllers for Liquid offer a “physical truth” in flow measurement that electronic sensors often struggle to match in terms of long-term drift resistance.

The efficient synergy between the high-resolution tapered tube and the precision-ground needle valve ensures that your liquid flow remains locked. Backed by Kofloc’s global reputation for excellence, the Kofloc RK1250 Flow Meters and Controllers for Liquid are built to provide years of superior service in the most demanding laboratory environments. When your liquid process demands efficient management and the highest tier of visual accuracy, the RK1250 series is the most dependable solution available.
