Purpose

To identify the location of various features of the laboratory and commonly used glassware

Expected Learning Outcomes

• Identify and describe the purpose of different pieces of glassware and laboratory features. (aligns with course learning outcomes 1, 3)

Textbook Reference

In conjunction with this section, you should read the section of the manual on Using Standard Laboratory Equipment.

Introduction

Throughout this course, you will be called upon to use and identify a range of different types of glassware, and you will be expected to be able to complete lab procedures by following the laboratory manual. This includes the ability to identify glassware and locate important parts of the laboratory.

To facilitate this, we have provided a range of activities that need to be completed during the first laboratory period.

Procedure

Grading and Logistics

For the purpose of grading, this experiment counts as a notebook only.  This report will be turned in at the end of the lab.  No lab notebook entry is required for this exercise.

For all future experiments, you are expected to keep and maintain a laboratory notebook and use the notes in your notebook to answer the questions in the short report for that experiment outside of class. The laboratory notebook (not your report) serves as the primary record of what you have done in the experiment.  Beginning next week, you will bring your lab notebook and prepared your pre-lab write up as described under Keeping a Laboratory Notebook.

For this week only, you will fill out the lab report form as you go along.  When you have completed this exercise, turn in your report form to your instructor.

Laboratory Drawer Check-In and Glassware Identification

Each pair of students will be assigned by your instructor to a drawer near your assigned lab space.

• Ensure that there are no loose chemicals or trash in the locker.
• Check that the list of items in your locker matches the list provided on the report form.  Be sure you can identify each piece of glassware.
• For some of the pieces of glassware (as identified by your instructor), you are required to:
  • Sketch the piece of glassware.
  • Show your instructor the piece of glassware in the laboratory.  Your instructor will indicate this by signing the appropriate space on the report form.

If any of the locker contents are missing, please be sure to inform your instructor. When you have completed the check-in process, please turn in your check-in sheet to your instructor.

Burets and Pipets

Burets and pipets are often used to measure out quantities of liquids. You will use this later in quite a few experiments, beginning with The Density of Water.

At the front of the room, you will be shown a buret, a volumetric pipet, a graduated pipet, and a P1000 micropipet. Sketch each of these and answer the questions provided on the report form.

Laboratory Layout

It is important that you are able to locate different items in the lab. Draw a plan (map) of the lab, including:

• Door(s) to the laboratory.
• Your lab bench.
• The location of the distilled water tap.
• Location of the balances.
• Location of the first aid kit.
• Location(s) of the clean, broken glass box(es).
• Location of the fire extinguisher.
• Location of the eyewash
• Location of the first aid kit.
• Location of the safety shower.
• Location of the fumehoods.
• Where the chemical waste beaker will be located.

Next Week: Safety and Glassware Identification Quizzes

• You are required to complete the Online Safety Check on Canvas.  Per department policy, you must obtain a perfect score on this quiz before entering the lab beginning the second week of the class.  You must take this once for each class held in a lab room (even if you have already taken the same quiz before in this semester or another semester).
• You will watch the safety video and complete the embedded questions in that video.
• At the beginning of your next lab period, you will have a closed-book, closed-note safety and glassware identification quiz covering:
  • The safety rules promulgated in the manual and the safety video.
  • Laboratory procedures as presented and given in your syllabus and this lab manual.
  • Identifying glassware as presented in this experiment.
