Diamond Scribe

This precision, 90° wedge-style (1 mm-wide blade) diamond scribe is different from most diamond point scribes available elsewhere. It’s the tool of choice by our own production techs. With proper technique, this scribe can be used to cleave even thin-wall tubing without damage and with minimum particulate generation.


Part Number: SCRIBE

PicoFrit Packing Mount

Acrylic base for the inspection of fused-silica tips by light microscopy; especially useful for holding PicoFrit tips during packing. The 1″ x 3″ baseplate is designed to fit any conventional mechanical stage. Includes MicroTight union and ferrules for 360 µm OD fused-silica tubing. Ideal for use with the PIP-500 Injection Platform.

Part Number: MOUNT-FS1

Fused-Silica Tubing

Pre-Cut Tubing

Simplify and improve your analysis with pre-cut fused-silica tubing. No more cleaving and hoping for a clean connection. Pre-cut tubing is professionally cut and polished to guarantee the best possible connection. 360 µm OD tubing is available in four ID sizes and five lengths.

Machine Cut
Machine cut and polished ensures fast, no-fuss, clean connections everytime

Good Hand Cleave
Good technique with diamond scribe or using a rotary cutter produces relatively good cuts

Poor Cleave
Usually results from ineffective scoring of fused silica and/or bending the tubing to “snap” it

Poor Cleave
Crushed tubing results from too much pressure and poor technique or inappropriate cutting tool

Ordering Pre-Cut Tubing

More Information

Using the right tools for making fused-silica connections can mean the difference between frustration and success.

Cleave fused silica using the proper diamond-bladed tool and with proper technique to ensure particulate-free connections. Or use pre-cut emitters and tubing for trouble-free connections.
