AI3151 LabSen 241-3SP Glass-body Micro pH Electrode for Micro-Volume Solutions Containing Proteins by Apera

Backed by proprietary Swiss sensor technology and premium materials, LabSen 241-3SP Glass Micro pH Electrode is designed for micro-volume samples (≥30 microliters) containing proteins such as serum and microbiological samples. With the ultra-micro container (sold separately), it can test as low as 15 microliters.

Unique Glass Membrane – LabSen 241-3SP pH electrode adopts a micro cylindrical sensor tip (top end ø3mm, stainless steel ø4mm), making micro-sample pH testing easier than ever, and can be tested in high-temperature samples (up to 212°F). The stainless steel protective shaft ø4mm) ensures the durability of the slim glass tube.

Protelyte electrolyte – A specialized oily reference solution made for protein solutions and viscous samples.

Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to achieve temperature compensation.

18004-14 Traceable ONE Single-Use USB Temperature Data Logger, 10 Day, 1 Minute Interval, 12 to 14°C; 10/pk by Digi-Sense

These data loggers can be used for monitoring and recording temperatures during shipments, storage, or experiments. They are ideal for food, pharmaceutical, or laboratory use any application where a small accurate datalogger is required.

The data logger features a time delay of 30 minutes so the logger will not alert when the temperature is within the alarm zone, until the delay time elapses. Protective plastic pouch keeps logger dry, eliminating concerns when shipping materials with cold packs, ice, or in damp environments. To maintain IP67 waterproof rating, do not tear open pouch before data download.

Products have an individually-numbered Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• LED alarm indicator for visual status indication
• Time delay of 30 minutes before logging begins for enhanced logging accuracy
• Protective plastic pouch maintains waterproof IP67 rating
• Bar code for in-house scanning
• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Compact, single-use datalogger with 10 day logging duration in 1 minute intervals
• Low to High alarm parameter range of 12 to 14°C

Includes

Battery (3.0 V CR2450 lithium) and NIST-Traceable calibration certificate with data.

MA882BOX Digital Refractometer For Wine & Grape Juice / Must Measurments by Milwaukee

Thousands of food and beverage professionals and hobbyists, from chefs and food quality professionals to brewers and wine makers, have moved to digital BRIX measurement from less accurate and less precise optical refractometers.

WHAT PEOPLE ARE SAYING

"Anyone who produces wine, grape juice or craft beer should find this product one of the best investments they make on any piece of equipment."

"I am in love with this instrument. No more large samples. No more phony readings from badly made refractometers."

"Dramatically improved my commercial brewing consistency & efficiency. Now I can quickly stop my sparge when I get to to my OG."

"I used this for finishing Maple Syrup. I had been trying to determine sugar content using temperature and a hydrometer. I found both very difficult to use. The refractometer was much easier."

SUMMARY

The Milwaukee digital BRIX refractometer is temperature compensated with a 0 to 50 percent BRIX range and +/- 0.2 percent accuracy. It is easy to use with simple two button operation and fast with a response time under 2 seconds. Maintenance is a breeze also with an easy-to-clean sealed flint glass prism and stainless steel well. The MA882 eliminates the uncertainty of optical refractometers by providing and accurate digital readout.

DESIGN FEATURES

• Fast, accurate results with digital dual level LCD readout.
• Easy measurement with just 2-3 drops of sample needed and results less than 2 seconds.
• Simple one-point calibration using distilled or deionized water.
