BT300-2J and BT600-2J Basic Peristaltic Pumps

DESCRIPTION

The BT300-2J and BT600-2J are variable-speed peristaltic pump drives for laboratories requiring more flow capacity than compact low-flow systems while retaining straightforward motor-speed control. The BT300-2J operates from 1 to 300 rpm, and the BT600-2J from 1 to 600 rpm. With appropriate heads and tubing, the manufacturer lists maximum single-channel reference flows of 1,500 and 3,000 mL/min respectively. Both support local operation and remote-control interfaces for research equipment integration.

Product Overview

These drives extend the basic-speed-control range beyond smaller benchtop pumps. The BT300-2J is suited to moderate laboratory transfer, while the BT600-2J increases the available rotational-speed and flow envelope for larger circulation tasks. The units are not volumetric feedback pumps: their LED display indicates rotational speed rather than an independently measured liquid delivery rate.

The same drive can be configured with different compatible heads, making the head-and-tubing selection central to the final system. For example, a high-flow configuration using a suitable YZII25 head will not have the same minimum controllable flow or tubing requirements as a smaller YZ1515x arrangement.

How It Works

Peristaltic rollers move a compression zone along flexible tubing, displacing fluid without routing it through the drive unit. The relationship between drive rpm and delivered volume varies with tube dimensions, pump-head geometry, fluid resistance and tubing condition. When a reproducible experimental flow rate is needed, measure and calibrate the assembled fluid path rather than relying solely on the nominal reference maximum.

Package / Configuration

Select a BT300-2J or BT600-2J drive together with its appropriate pump head, tubing and any required control hardware. Compatible head families include YZ1515x, YZ2515x, YZII15, YZII25 and specified DG15-24 configurations. Do not assume a head, tube set, footswitch or dispensing attachment is included unless identified in the quotation. An external dispenser attachment is an optional means of adding certain delivery functions; it does not turn the basic drive into a built-in calibrated dispensing system.

Applications

These pumps can serve laboratory liquid transport, reagent transfer, reservoir circulation, testing rigs and compatible electrochemical flow studies. In an MEA installation, one drive may circulate an electrolyte on one side of a cell, but anolyte and catholyte circuits generally require separately adjustable drives if independent flow control is necessary. Selection should be based on the actual target volumetric rate and pressure drop, not on the motor's maximum speed.

Compatibility and Selection Guidance

Confirm the selected head, tubing size, chemical compatibility and required number of channels. Some heads support multiple tubing tracks, but channels driven by the same motor normally share its rotational speed. Verify pressure restrictions and possible pulsation for the proposed electrochemical cell or analytical instrument. Customers requiring calibrated flow settings or detailed dosing sequences may prefer the flow-rate or dispensing categories instead of a basic drive.

Frequently Asked Questions

What is the difference between the two models?

The BT600-2J offers the higher speed ceiling and maximum listed single-channel flow; the basic control approach is similar.

Does a 3,000 mL/min specification apply to every head?

No. It is a maximum reference value associated with a particular compatible head/tubing arrangement. Other configurations provide different flow ranges.

Do these pumps display volumetric flow?

The built-in three-digit display reports rotational speed. Actual flow must be established for the assembled fluid path.

Can they be integrated with a laboratory controller?

Both list external-control inputs and RS485 communication. Confirm wiring, signal range and communications compatibility.

Can one drive independently control two electrolyte streams?

Not merely by mounting two heads. Shared-motor heads ordinarily run at the same speed; independent adjustment calls for separate drives or a specifically engineered independent-channel system.

Is tubing supplied with the drive?

Head and tubing provision depends on the ordered configuration. Confirm all included and separately priced items on the quotation.
